The Best Node.js Framework: Koa VS Express VS Hapi [Detailed Comparison]

Since its launch in 2009, Node.js has become one of the fastest-growing open-source, cross-platform Javascript run-time environment and therefore, many Node.js web frameworks were created. Each framework is catered to the demands of users and developers, such as to improve productivity, scalability, enhance the speed of applications and performance capability. With the advantages of being lightweight, scalable and many others, no wonder Node.js web frameworks are rapidly gaining attention and becoming the go-to option for developers at the present.

In this article, we will introduce the three most popular web frameworks in Node.js (Express, Koa and Hapi) and how to differentiate them to pick the right one for your project.

Today you’ll learn: 

  • Full faces of Express, Hapi and Koa frameworks.
  • The differences among them.
  • Why they form a squad of biggest popularity.
  • The best framework for your business strategy.

Heat up yet? Let’s start the learning journey!
The Best Node.js Framework: Koa VS Express VS Hapi [Detailed Comparison]

1. What are Express, Hapi and Koa?

To keep you from dropping dead before the mind-boggling information later in this blog, I’ll flash through the basics of each of the 3 frameworks as following:

1.1. Express

Express is a code-centric web application framework that aims to provide developers with a simple, performant, and unopinionated toolset for creating web application servers. The API is kept lightweight and maintains a high degree of consistency with the NodeJS core API. Because of its minimalist nature, many common tasks require outside modules.

Having been in development since 2009, Express is a mature project with a strong community backing. With +43000 stars on GitHub and about 8 millions npm weekly download, Express has proved its reign as the most loved and widely used Node.js web application framework. The latest version of Express is 4.17.1 published in May 2019. The publisher also announced on its 5.0 version, which is currently in the alpha stage, promising the upcoming dawn of Express 5 universe.

1.2. Hapi

Hapi is a feature-rich framework that favours configuration over code and attempts to cover a wider range of use cases out of the box. It was originally created by a member of WalmartLabs, and it is intended for large teams and large projects. Because of this, it can be a bit boilerplate-heavy for small projects.

While Hapi is less widely used and slightly newer than Express (Hapi started development in 2011), Hapi is used by a variety of large companies such as Walmart, Disney, and Macy’s. It has more than 11000 stars on GitHub and over 250000 npm downloads each week.

1.3. Koa

Koa is a new web framework designed by the team behind Express, which aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. By leveraging async functions, Koa allows you to ditch callbacks and greatly increase error-handling.

Koa does not bundle any middleware within its core, and it provides an elegant suite of methods that make writing servers fast and enjoyable. It scores quite impressive stars on GitHub: +25000, earning approximately 300000 npm weekly downloads as of today despite its being one of the newborns in the Node.js game.

2. KOA vs EXPRESS vs HAPI: A Detailed Comparison

Let’s differentiate the three most popular Node.js frameworks to find which is the best for your project. Here are some of the criteria that we think you should take into consideration:

  • Basic Setup
  • Middleware
  • Installation
  • Performance
  • PROs and CONs
  • Community

2.1. Basic Setup

Here comes the start of the complicated part. Because Express, Happi and Koa are all unique in each’s own way, with several distinctive traits and functionalities. The basic set up is not an exception. To start off, let’s make a new server, tell it to start listening to port 3000, and have it log a message when it has done so.

Express

The basic setup in Express is pretty straightforward. The express module returns a function (with some helper methods attached) which will return a new Express app. The return value of app.listen is an instance of HTTP.server.

Just look at these codes as an example:

const express = require('express');
const app = express();
const PORT = process.env.PORT || 3000;
const server = app.listen(PORT, () => {
console.log(`Express is listening to http://localhost:${PORT}`);
});

Hapi

The basic setup for Hapi looks very similar to that of Express, although Hapi’s focus on configuration over code is already beginning to make an appearance. After instantiating a new Hapi server, we add a connection, providing it with the port via a configuration object. Then, we simply start the server.

For example:

const Hapi = require('hapi');
const PORT = process.env.PORT || 3000;
const server = new Hapi.Server(PORT);
server.start(() => {
console.log(`Hapi is listening to http://localhost:${PORT}`);
});

Koa

Because Koa was given birth by the same team as Express, the basic setup of those two can be quite confusing at first glance.

const koa = require('koa');
const app = koa();
const PORT = process.env.PORT || 3000;
const server = app.listen(PORT, () => {
console.log(`Koa is listening to http://localhost:${PORT}`);
});

Right away you can see the similarities., but essentially you just required Koa instead of Express. We even have the same app.listen() wrapper function. Still, what makes Koa really separates from Express, as introduced in the first part, is its way to ditch callback completely by either using ES6 function generators or the newer async/await control flow. It also eliminates much of the middleware that Express uses, which at some points become even more dominant than Express.

2.2. Middleware

One of the major concepts Node developers are used to is working with middleware. Middleware functions are functions that sit in between requests and responses. They have access to the request and response objects and can run the next middleware after they’re processed.

To understand the competency of each, let’s take a look at how they’re defined in the different frameworks by implementing a simple function that logs the time a request is made to the server.

Express

Registering middleware in Express is as simple as binding the middleware to the app object by using the app.use() function.

For instance:

app.use((req, res, next) => {
console.log(`Time: ${Date.now()}`);
next();
})

Hapi

In Hapi there are certain extension points in the request lifecyle. The server.ext() method registers an extension function to be called at a certain point in the request life cycle.

We make use of the onRequest extension point in the example below to register a middleware (or extension) function:

server.ext('onRequest', (request, h) => {
console.log(`Time: ${Date.now()}`);
return h.continue;
});

Koa

Middleware registration in Koa is similar to Express. The major differences are that the context object (ctx) is used in place of the request and response objects in Express and Koa embraces the modern async/await paradigm for defining the middleware function.

Take this as an example:

app.use(async (ctx, next) => {
console.log(`Time: ${Date.now()}`);
await next();
});

2.3. Installation

The installations of Express, Koa and Hapi are also differentiated as below:

Express

For installing Express, you need to have already installed Node.js. If you want to install Express in a specific directory and save it in the dependencies list:

$ npm install express --save

However, if you want to install Express temporarily and not add it to the dependencies list, you can use:

$ npm install express --no-save

Hapi

To install Hapi, you need to have Node.js installed and then:
$npm install Hapi
to save it to your package.js on dependencies.

Koa

Koa requires node v7.6.0 or higher for ES2015 and async function support. You need to have already installed Node.js. You can quickly install a supported version of Node.js with your favourite version manager:

$ nvm install 7
$ npm i koa
$ node my-koa-app.js

2.4. The “Hello World” Example

To dig even deeper, let’s take a “Hello World!” example, put it as listening on port 3000 and responds “Hello World”.

Express

This is the most basic example of how to create an express app that listens on port 3000 and responds “Hello World”. For every other path, the server will respond with 404 Not Found.

const express = require('express')
const app = express()
const port = 3000app.get('/', (req, res) => res.send('Hello World!'))app.listen(port, () => console.log(`Example app listening on port ${port}!`))

Hapi

The following example is the most basic hello world app using Hapi. Then you just launch the application by running npm start and open localhost: 8000/hello in your browser.

'use strict';const Hapi=require('hapi');
// Create a server with a host and port
const server=Hapi.server({
host:'localhost',
port:8000
});
// Add the route
server.route({
method:'GET',
path:'/hello',
handler:function(request,h) {
return'hello world';
}
});
// Start the server
const start = async function() {
try {
await server.start();
}
catch (err) {
console.log(err);
process.exit(1);
}
console.log('Server running at:', server.info.uri);
};
start();

Koa

This is the most basic example of a “Hello World!” app on Koa that listens on the port 3000. For every other path, the server will respond with 404 Not Found.

const Koa = require('koa');
const app = new Koa();app.use(async ctx => {
ctx.body = 'Hello World';
});app.listen(3000);

2.5. Performance

The performance is, for the most parts, one of the most important parameters for you to evaluate its quality as well as the suitability of it to your business model. In this part, we are going to elaborate on the performance of each of them so that you could have a thought on the framework you think the best you should choose.

Express

Express provides a thin layer of fundamental web application features, without obscuring Node.js features that are familiar.

The best practices for improving express performance includes:

  • Use gzip compression.
  • Don’t use synchronous functions.
  • Do logging correctly (for debugging, use a special module like debug, for app activity use winston or bunyan).
  • Handle exceptions properly, using try-catch or promises.
  • Ensure your app automatically restarts by using a process manager or use an init system like systemd or upstart.
  • Run your app in a cluster. You can increase the performance of a Node.js app greatly by launching a cluster of processes (a cluster runs multiple instances of the app, distributing the load and tasks among the instances).
  • Cache request results, so that your app does not repeat the operation to serve the same request repeatedly.
  • Use a load balancer to run multiple instances of it and distribute the traffic, like Nginx or HAProxy.
  • Use a reverse proxy that performs supporting operations on the requests. It can handle error pages, compression, caching, serving files, and load balancing among other things.

A simple “Hello World” app has the following performance request per second:

As we can see in the following graph compared to Express.

The Best Node.js Framework: Koa VS Express VS Hapi [Detailed Comparison]

  • Express continues to maintain a performance edge over Hapi.
  • Applications with significant performance requirements should consider the advantage Express has over Hapi.

A simple “Hello World” app has the following performance request per second:
The Best Node.js Framework: Koa VS Express VS Hapi [Detailed Comparison]

Koa

With Koa, you can build web apps with great performance. This is because you can stop using callbacks, deal with errors faster, and because Koa itself is a very lightweight framework. As well as that, it makes the code management process easier.

It’s important to take into account the best practices for having a better performance in Node.js like running things in parallel, use asynchronous APIs in your code, keeping code small and light, and using gzip compression.

2.6. Pros & Cons of Each Framework

Understanding that you might be tired after reading the wall of text I’ve just written above and because it is too long of information for you to swallow, you probably missed out somewhere; I will summarise the upper and lower hands of each so that you’re easier to compare among three of them.

Express

The Best Node.js Framework: Koa VS Express VS Hapi [Detailed Comparison]

  • Advantages

Express has the biggest community of users out of all existed web application frameworks for Node.js, with a history of over 9 years of development behind it. Many of its members praise that Express is a good and powerful tool, and it does do a good job.
Because of its simplicity, Express is very user-friendly and can be applied successfully by inexperienced people. It also helps simplify the testing process and improve application performance.
Despite that, with a powerful rooted API, various tasks can be performed including building an Express RESTful API server and routes for simple web applications. Additionally, it’s extremely easy to integrate with third-party services and middleware as Express makes use of the Node.js manager package node.

  • Disadvantages

While it is a convenient and easy-to-use tool, Express does have some drawbacks. One of those is the lack of a recommended method of organisation, which can be a problem for developers as they’re unable to repair the projects if needed.
Therefore, it is important to be very clear about the approach when maintaining the code. Furthermore, Express required a lot of manual labour-intensive tasks since you need to create all endpoints. Unless it’s handled professionally, the problem can affect a great deal to your memory usage.

  • Recommendation

For small and middle-size projects, Express would be a suitable option. Some of the examples that can be named are MySpace, PayPal and Klout sites, which all use the Express web framework as a middleware framework.
However, if you’re going to develop a complex project with a large development team, Express may not be the best tool to use.

Hapi

The Best Node.js Framework: Koa VS Express VS Hapi [Detailed Comparison]

  • Advantages

Hapi is Node.js framework with a powerful provided plugin system, therefore developers can add new features or fix bugs at a fast pace. As well as that, Hapi can assist you to manage the whole development process easier.

As Hapi allows developers to have deeper control over request handling, building large scale or enterprise-sized applications is a piece of cake. On top of that, as this framework is based on configuration rather than code, Hapi adds consistency and reusability to the developing process.

  • Disadvantages

Apart from being a useful tool in creating customized construction blocks, Hapi does have a considerable minus. This framework relies heavily on manual labour, which means you’re on your own to figure out how to use them.

There are a lot fewer samples or open-source applications that use Hapi, so the project may involve developers more than when using third-party middleware.

  • Recommendation

As Hapi is tailored towards big and complex web applications, if you’re in the process of building one app like that, you should definitely go for this framework. With the back-up of WalmartLabs and many other large companies that have already used Hapi, you can rest assured that this web framework has been tested and ready for any heavy tasks.

Koa

The Best Node.js Framework: Koa VS Express VS Hapi [Detailed Comparison]

  • Advantages

By taking advantage of ES6 generator feature, using Koa will help you avoid callbacks and build web applications with great performance. Besides, it makes the coding management process easier. Hence, you can easily handle errors faster.

Moreover, with just over 500 lines of code, Koa is an extremely lightweight framework, making it a special point of this tool. Overall, Koa brings a faster and easier experience when picking (or writing) middleware for first-timers, rather than compromising with middleware like Express or Hapi.

  • Disadvantages

Despite its pros, Koa still presents some hindrances. As it is the newest out of three frameworks (Express, Koa and Hapi), the open-source community revolving around Koa is relatively small. Therefore, it suffers a shortage of support from its web framework community.

In addition, Koa is still unstable. Using the ES6 generator, which is way above of the game, means that Koa framework is not compatible with any types of Node.js framework middleware existed.

  • Recommendation

As Koa is a lightweight and modular framework, you can create a web application from scratch, upon request and without tonnes of unwanted materials.

Conclusion

There is no “best” framework among Express, Hapi and Koa. They are equally distinctive, remarkably unique and constantly innovative while keeping the nature of Node.js as being light-weight, scalable and performant. They are all excellent framework, in their own different ways.

That being said,  it’s a battle with all three of them co-awarding the first prize, with each of them comes with both pros and cons, advantage and drawbacks as well as various distinctions in core competency, basic setup, middleware, installation and community.

What really matters is you choose “the one” for your business – the framework that matches your products, your business goals, strategy and organisation. Otherwise, it means nothing even if you pick out the most popular or the fastest performing one.

To do that, you shall:

  • Make a list of core traits of your business (such as your company structure, business goals, development strategy, product competency, target market, etc).
  • Read carefully the above information to pinpoint the nature of each framework, which can be optimised by the below bullet points:

– Express: Lightweight and minimalist, supported by most middleware, seems to be the defacto standard.

– Koa: Great async/await support for asynchronous flow. Seems to be ‘the new hotness’.

– Hapi: Great for larger-scale projects out of the box, but has some extra middleware to deal with.

  • Analyse the information about your company in comparison with those above bullet points to strategically decide on the most suitable for your business. Remember, just because it is popular doesn’t mean it is going to make you “happy” – sometimes a “less impressive” one is all you need for a long, healthy relationship.

Make sure you fully understand the differences and carefully collate your business to it, so that you won’t regret choosing a dull one later! If you are still confused about which framework you shall apply for the best business efficiency, feel free to contact us for professional consultations! We would be happy to help you make a leap in the industry.

Node.js in Web Development – Key benefits

Thanks to Node.js Development Service, websites now can be scalable network applications that work properly with various operation systems threads. With the chance to open up the vast amount of open source libraries of technology, Node.js is no doubt to be one of the best choices at present.

node js web development, node js benefits

And this choice was affirmed by Walmart, Intel, NASA, IBM, Paypal, LinkedIn, and many more big cooperations. Being curious about the reason why Node.js is so appealing? Let’s take a further step into the world of Node.js in web development.

Why Node.js Web Development is faster than others?

Non-blocking Input/Output operation (I/O operation) is the main reason that makes people say: “Node.js in web development is faster than others’. In other words, Node.js runs on callback-based asynchronous IO: requests can be automatically queued and served by a thread; once the first request has been finished, it gives call back to the thread and the next request is ready to be in the process. Therefore, the time between requests is optimization saved, in contrast to the Apache server, when there is waiting time between.

It is more noteworthy that Node.js is an excellent platform for the data-intensive real-time application that runs across distributed devices. It is also specifically designed for writing scalable Internet applications, prominently in developing web servers. Its remarkable performance is proved based on the architecture of many Internet applications.

Other outstanding features of Node.js Web Development

  • Scalability

Node.js assists IT programming developers to scale the application in both horizontal and vertical ways. Hence, the performance of the application is improved; crashes and other risk issues is significantly mitigated.

  • Testing now is easier with Node.js

With the assistance of Node.js in web development, unit testing is not a big obstacle anymore. Getting access to the vast amount of good testing libraries of Node.js, developers now can spend less time in this task to have more time to do other important tasks.

  • Node.js is one of the most extensive package ecosystem ever!

At the end of 2016, there are about 400,000 packages and steadily go way higher up to this day. Is this statistics impressive enough for you?
And it gets updated every day! Npm (Node.js package manager), considered to be the world’s largest Software Registry. According to ‘State of the Union: npm’ published in January 2017, “4,685 packages were published in the registry” in a week. It seems to be “never be outdated” with Node.js ecosystem, right?
In 2018 Node.js User Survey Report by Node.js Foundation, Node.js is the most popular package manager, which takes up to 60% of the overall package manager usage.

  • Network application development

With its built-in Application Programming Interface (API), apparently, Node.js Development Company can easily be able to develop different sorts of a web server, chat server and other network application such as DNS Server, Jigsaw servers, TCP servers, HTTPS Server, etc.
Or with your diligence and persistence, you can build a simple web server with Node.js in your own way. There are many detailed instructions and steps out there on the Internet, also in the book “Get programming with Node.js”.
Or you can contact Savvycom to book a FREE consultation about building network application development.

Key benefits that Node.js Web Development offers us

There are some things you might know: JavaScript is an IT programming language running in web browsers. Node.js is the running environment for JavaScript which holds a variety of libraries. And the V8 JavaScript engine is the one executing JavaScript codes.
Now, let’s come back to the benefits. What are these things?

  • Lightweight and scalable

Thanks to V8 JavaScript engine, Node.js Web Development process is more efficient along with its assurance about quality and security. As I mentioned before, non-blocking I/O operation of Node.js application is the main factor that makes ‘lightweight and scalable’ to be the character of your application.

  • Microservices are perfect for Node.js Web Development projects!

Clients tend to choose Node.js for their microservices over others, to optimise the performance of an application. With the support of Node.js platform, you are able to process your application while still using it, scale the parts that are not available yet in your application. Moreover, some unproductive modules can be cancelled at the same time you do below things. This kind of separation of many tasks is the “easily done” factor in microservices operation on a Node.js application.
Mentioned by Stephen Commisso (Senior Software Engineer of GoDaddy) in Node Summit 2015, by rightly utilizing microservices and Node.js, it’s totally capable of handling the same load with only 10% of the hardware.

  • Shorter Time to market

Compared to Java Development Companies, Node.js counterparts are able to meet your requests and give you a full server or application in a shorter time. Node.js’s advantages over other platforms I can list is the modular structure, few lines of codes, agile development and collaborative development approach of Node.js framework.

  • The more striking performance capability of Node.js Web Development

The node.js application can work flawlessly in the fast pace due to Non-blocking event-driven I/O. More detailed, Node.js Development Services optimize the data by reducing its occupied storage space, therefore its speed is boosted 20 times faster!
In the case of Paypal experiment, compared to the previous version of the Java-based application, Node.js Mobile application development manages to cut the response time by 35%. That’s the reason why Node.js Web Development is more preferred to create the high-performance application.
Currently, Node.js framework has passed by many functional characteristics of Java and .Net platform in the field of business app development.

  • Node.js Web Development is constantly innovated

Improvement and improvisation in Node.js Web Development are always taken into consideration. That’s why they have a good intention to find their way to launch new releases and enhances the standards of its codes and features. With ES6 Spec for JavaScript and the support of an open source community, Node.js technology will develop more and become more innovative in the future.
And if you are still wondering how the development focus of Node.js Web Development has changed, let’s look into the statistics of 2018 Node.js User Survey Report by Node.js Foundation

PHP vs Python in Web Development: Core Strengths and Functions

There are so many languages in the world when people communicate with each other, and so do IT programming languages. With their own function, the way of usage and variation, each IT language has proved its strength and advantage in their particular main field. Among them, PHP and Python are the 2 most prominent candidates for your choice.

php vs python in web development

So, how can you choose between PHP and Python? Let’s check out some comparisons to figure out!

Purpose and core strengths of PHP

First, with PHP, what do we have? It is said that the intention of creating a PHP language is to produce dynamic web pages in web development. More specifically, server-side scripting is one typical advantage of PHP to ‘win over’ Python if we still doubt about our selection. What CGI (Common Gateway Interface) program can do, PHP can too. From generating dynamic page content, collecting form data to sending or receiving cookies, nothing can be difficult when you have PHP in your hand!

Back to its main core strength of PHP, server-side scripting, we need to provide 3 things to make it run properly: the PHP parser (CGI or server module), a web server and a web browser. Once you install PHP connection, run the web server, now you can access to the PHP program output with a web browser, therefore you are able to view the PHP page through the server.

The second advantage of PHP you can’t miss is command line scripting. One good point to run it compared to server-side scripting is that you only need the PHP parser. A web server and a web browser, in this case, are not necessary. And how can we use this convenient and minimal type of scripting? Well, it’s dedicated to scripts regularly executed using cron (on *nix or Linux) or Task Scheduler (on Windows). Simple text processing tasks can be applicable to this case, because of the convenience of command line scripting.

Last but not least, writing desktop applications cannot be excluded in the core strength list of PHP language. Maybe it’s not the most optimal language to build a desktop application, but if you are an expert in PHP language, it did pay off and you can manage to do it. Some advanced PHP features like PHP-GTK can support you in improving graphical user interface in your website, as well as writing cross-platform applications.

Purpose and core strengths of Python

If the main purpose of PHP is to produce dynamic web pages, Python finds its own ‘life purpose’ to shine. With the intention to emphasize productivity and code readability, Mr Guido Van Rossum invented the Python language to assist programmers to complete their tasks faster.

Specifically, on web development, you can develop a web application with the eminent assistance from Python. There are libraries for internet protocols in Python language like HTML and XML, JSON, email processing, FTP, IMAP, and easy-to-use socket interface, which is definitely helpful for programmers.

Being one of the most diverse IT languages, Python has quite many prominent features that outshine PHP in their niche field.

In the ‘battle’ of how easy to learn, Python totally defeats PHP. Python is an easy language. ‘Very friendly welcome’ to beginners. It is recommended by programmers due to the simplicity of its syntax, and it seems to have no barrier for beginners to learn and understand Python language. In contrast, PHP is more difficult, requiring you some basic knowledge about the C program. It is not necessary that you have to learn C program first, but there will be some obstacles of understanding if you are not familiar with the C program at the beginning of learning PHP.

As you may know, Python is executed line by line. That’s why it is much easier to test and debug during the web development process.

One of the most remarkable features of Python, in my opinion, is Free and open source. It is totally FREE to have access to the language and its source code. A costly license doesn’t exist with Python, and it is such a great way to save budget in doing other improvements. What can be more amazing than this wonderful free language?

And if you use PHP-GTK to develop the Graphical User Interface (GUI), Python has its own ‘weapon to fight’: Tkinter to solve this challenge.

Last but not least, the large standard library Python provides is the truly convenient core strength of the language. With the support of the library, you now can implement a quite amount of functions without reinventing the wheel every time. So simple, just pick the code you need and continue.

Which operating system and web server PHP and Python can run on?

Two words I can say about that: ‘So many!’. Because the creator of PHP language, Mr Rasmus Lerdorf, don’t want to have any limit of the language to any operating system. That’s why PHP can be applicable on Linux, Microsoft Windows, Mac OS X, RISC OS, numerous Unix variants (including HP-UX, Solaris and OpenBSD) and so on.

In this operating system match, Python is very competitive too. As I mentioned above, Python is an open source, so basically, it can run on Windows, Linux, Mac and any other platform. You don’t need to change for every machine to make your program work. So, I guess this round is drawn.

Which web server does PHP support? The same answer as ‘Which operating systems’: a wide variety: Apache, IIS, any web server utilizing the FastCGI PHP binary (such as Lighttpd and Nginx). Don’t be so surprised if I told you PHP can work as a CGI processor. Such a versatile IT language!

So, PHP open whole new, almost-unlimited choices, not only operating systems and web server I mentioned above, but also procedural programming and object-oriented programming (OOP), and even a mixture of both. Amazing!

Remind you, Python is also an object-oriented language. Considering this object-oriented field, I’m not sure which one is the winner.

But, PHP has another advantage. The limitation to output HTML with PHP broke off. Now, we can output images, PDF files, Flash movies and of course, any text as well. With the ability to auto-generating these files, save them in the system, PHP can form server-side cache for your dynamic content.

Top 8 Enlightening Web Design Trends for Your Business in 2019

Several years ahead and web design trends have developed exponentially along with a flow of creativity. Abandoning grids, simple stock photos for lively illustrations, bold colour schemes and asymmetrical layouts…

Otherwise, technological advancements have optimized websites to be more friendly and convenient, with machine learning and subtle interactions. Web design trends 2019 are the integration of aesthetics and technology – 2 crucial factors accelerating websites interface.

Many creative innovations have been discovered so far, yet we can expect it will go much further and beyond in the future. While waiting for new development, let’s look at some outstanding case studies below to predict web design trends 2019

top web design trends 2019 by savvycom

1. Serifs on screen – is it true?

Maybe we heard somewhere a common rule that we print with serifs fonts and sans serifs are for the screen. Several years going by, has anything changed? Whether or not web design trends can break the rule like a rebellious student?

Because of its clean readability, Sans is more favourable in various website interface. Yet, more and more brands are shifting towards bold serifs including in their designs such as headers and callouts. Things you may know, serifs were designed to be a decorative font, and making them emphasis is a good choice.

Serifs may surprise you with lots of character and its adaptability to use in creative ways. Rounded serifs in Mailchimp’s funny image contribute to depict positive brand outlook. Or you can reference wedge serifs and bold strokes that make Medium look modern and professional.

2. Simple but Subtle Black-and-white palettes

black and white style in web design trends 2019

Colour is one of the first things attracting your eyes when you visit a website. It understates but stimulates our mood, defines a brand and creates visual landmarks in support to guide users through an interface. In 2019, simple but excellent black-and-white web design can make a strong statement sending out to the world.

Physically, colour is the way reflecting light particles to our eyes, like a lively filter to see the world. When colour disappears, textures and shapes become more obvious, and the world seems to be prominently sharper, slower and edgier.

White represents cleanliness, purity or softness. On the contrary, black is powerful and assertive. Those two combination impresses us a completely striking look.

Not so surprising that the most apparent effect of black-and-white designs is in their combination with minimal amounts of colour. To make your design more impressive, add an emphatic colour. Not only the new colour in the sea of monochrome is embellished and highlighted, but eventually, points of interest and calls-to-action stand out.

3. Natural, organic shapes

Most of the time, systematic grids have been used to build up a website as a basic element. Yet, natural shapes and smooth lines tend to be a favourable design trend in the upcoming time. Geometric shapes such as squares, rectangles and triangles with sharp corners to create a sense of firmness and stability, but web design trends 2019 focus on customer experiences with a feeling of accessibility and comfort.

Naturally flexible and asymmetrical, organic shapes can make your web design eye-catching and noticeable. Free-drawn strokes with alike natural cubes can capture the spontaneity of man-made accidents such as paint splatter. Efforts to create those things for the main goal here is to make web designs friendly and alive through the illusion of movement.

4. Glitch art

Trends list wouldn’t be perfect without the presence of retro design. Since the time computers have become pervasive, glitch arts go along with this development to imprint their mark in design fields.

If you want to create motion into your design (like cinemagraphs), glitch effect is one tool to make it happen! Depending on your purpose and which motions you want to add, glitch effect is ready to shine the light into your work. Old-tech feel or a futuristic curiosity – make the most of its versatile use of this effect is a good strategy.

5. Micro-interactions

micro interaction take important role in web design trends 2019

To surprise the user and create an event that is inviting and human, micro-interactions is created. In detail, it means: “Every time you take a small action on a website or app and there is a specific response to it”.

And you stumble upon these every day in case you still don’t know what it is. Every time you refresh a Twitter page and hear a beep, there it is. Or the time you scroll through Facebook pages and suddenly, a red icon displaying you have a new notification. And what is it? Of course, it’s a micro-interaction.

It can be applied more than a social media foundation. In 2019, feature more these micro-interactions on websites will be more popular and common. This is an effective way to interact with your audience and your potential customer on the website, to subtly transmit core information to the users based on their actions and usage, overall make web pages have a better user experience.

6. Chatbots and how AI elevate it

If you offer a product/service to end-user, chatbots are already familiar to you. Along with AI and machine learning development, chatbots at present are more intelligent and efficient in understanding customer’s need.

Don’t so surprised that more and more chat boxes will show up on every web pages you click through. Bright colours shine your page in customer’s eyes. Moreover, friendly mascots representing brands can appear as a chatbox with a personable face.

7. Can’t exclude Video content!

video content is important in web design trends 2019

Since content marketing has become one of the key tools to draw the attention of the target audience, video content is much appealing than ever before. For example, it users to go through all long-texted instructions and save their time. And you don’t want to read a boring only-texted article, right?

What’s new is Google has widened its preferred search results to mixed content, featuring video content above standard web pages. Therefore, websites now are initiating to prioritize video production so as to make theirs easily searchable and bringing out content in the most efficient, shareable way.

8. Minimalism

Minimalism – One of the web design trends will never be outdated. The fewer elements and content on a website, the less your audience will have to think. If a website is designed and optimized in the proper way, it will show the user exactly what they are looking for.

We can say that Minimalism will keep dominating web design trends 2019. Not only interesting to see animations and fade-in effects, but web pages have more space for their focused content. Thus, we have more whitespace, contrast and clear typography, leaving out many distracting elements to have wonderful websites

Back-end development supports for front-end stability

Hiring a back end web developer to expand your capabilities on the world wide web can provide a more unique presence tailored to your needs. Outsourcing an expert back end web developer could be the ticket. Sure, there are many out of the box solutions that you might consider. However, in a world of copy paste, monkey sees monkey do websites, a totally new experience could enhance your chances of success.

When the internet was relatively new, websites were made by hand-coding HTML and similar languages. You pretty much had to know what you were doing. It was several years before services like Angelfire and Geocities became available. Any company wanting to build a presence on the internet had to hire savvy (no pun intended) developers with expertise that was learned through hours of studying and trial and error late-night programming attempts.

backend development supports for front end

After a while, there were many applications built to make it easier for the normal person to create content and share it on the internet. Besides the examples already mentioned, CMS apps like WordPress and Joomla were created to make it so that anyone could start their own website on their own host. This had positive and negative effects, some intended, some not.

Script Kiddies

Back in the day, (yes I said that), hackers created tons of scripts that could be used by either tricking victims into downloading it or direct injection by the user. Viruses meant to steal information could be loaded via the 1.44-inch floppy drive. On network aware machines, often times the virus had hidden code meant to send the stolen information back to the original creators’ storage location of choice. So you get what you wanted, but at what cost? Any information the junior hacker thought he had that was worth something is now worthless because the other guy has it too. The point is that creating your own code gives you peace of mind. No one will have scripts ready to demolish your pitiful WordPress security, because you have a totally unique data structure that has never had scripts written for it.

Not everyone has the time to become a programmer, however. You might already have a great idea for a website or mobile app, but you aren’t a backend web developer and don’t want to be. What to do?

In house or Outsourcing software development to a company like Savvycom?

web backend development by savvycom

Of course, Savvycom being a software outsourcing cooperative, we almost always recommend letting professionals such as ourselves handle the dirty work for you. We have a team of backend web developers with extensive combined experience, so we are confident we can help you. But is hiring an outsourcing company right for you? If you were to hire your own employee, you’d have to deal with a host of complications and expenses that wouldn’t be of any concern if you outsourced. The only occasion we recommend using your own employee is if you know and trust them and they have years of verifiable track record. Your project is small and you don’t require any promise to follow up or updates. We are fairly confident that in any case, teamwork is always better. You can pay for all of the expenses associated with an employee, or you can spend the same amount and receive the care and attention of an entire team of dedicated backend developers.

If you are skilled in basic web design and creating apps already, this could enhance your ability to showcase your front end offerings faster. While you work on front end interface ideas and infrastructure, Savvycom has your back on back end support. We can work with you and your team to create the perfect solution. If, however, you desire full-stack service and support, we can help you with that as well. Whatever you desire, front end user friendliness and usability are deeply integrated with back end technologies, so you will have to decide if it is in your best interest to do half of your work in house or to let a team of professionals who are passionate about their work take care of the whole thing for you!

front-end development, back-end development, server side

How back-end will support front-end development

It is the writer’s personal opinion that trust is the number one issue when considering who to handle your entire investments basic functionality. Savvycom has a long track record of satisfied customers. We’ve seen plenty of good looking apps that didn’t function correctly. A pretty front end doesn’t help if the website or app crashes every time someone wants to use it. Front end stability, compatibility, and versatility are all achieved through patience and understanding of the task given and the needs stated.

Outsourcing a backend developer allows you to focus on that pretty front end (which we can help you with as well!) without worrying about failure right off the bat, or worse, a glitch unseen until a customer finds it while trying to make a transaction! Even huge teams of developers can miss small details. Just look at major games like World of Warcraft. The Corrupted Blood incident was a lesson for them and programmers around the world. Savvycom has a moderately sized team that is neither too small or big, allowing free-flowing communication in a comfortable environment. We believe that team happiness is absolutely vital to end productiveness.

So, if you would rather not wait because you have a million-dollar idea, or perhaps you have been on the fence about leaping into a project where you have to deal with every gruesome detail of app development, you might want to look into outsourcing backend web development… hopefully with Savvycom!

When and Why should we use Node.js technology in software development?

Nowadays, JavaScript is the most popular programming language and one of the foremost widespread software development technologies. With its popularity, it has dramatically changed the face of web development. A few years ago, it was magical what we could do with JavaScript, for instance easily running in the browser as well as on the server. If there is a web application project in mind, developers might think about building stack around JavaScript and other tools. After that, they will surely come across Node.js technology for the back-end development platform. Node.js is a tool that fueled the buzz around the use of JavaScript for server-side programming.

node.js technology for software development reasons

What is Node.js?

Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine for easily building fast and scalable network applications. Due to its event-driven and non-blocking, I/O model makes it very efficient and lightweight. Node.js is a cross-platform runtime environment for developing server-side and can work within the Node.js runtime on OS X, Linux and Microsoft Windows. Moreover, it opens new opportunities for developers because it uses JavaScript on the front-end and back-end. For the last few years, Node.js technology became a trend and provides lots of off-the-shelf solutions. Additionally, it was used for variety mid-sized projects, however, a few years ago its capabilities took a major leap forward. As a consequence, Node.js takes advantage of a good ratio between product performance, developer effort and exceptional scalabilities. Overall, Node.js technology has become the most favoured JS framework for almost all web developers.

How is Node.js technology different from web JavaScript?

In terms of language, there is no difference between web Node.js technology and JavaScript technology. To be specific, Node.js has a different set of APIs. In browsers, you have a variety of Web APIs uncovered that assist users to connect with UI. Also, it offers some supports such as file systems or HTTP request, however, they are limited due to security concerns. Meanwhile, Node.js assists with different APIs suitable for back-end development.

What is Node.js technology used for?

realtime application using nodejs

To achieve the best application performance in web development, Node.js is used for real-time applications, collaborative tools and data streaming applications. Firstly, Node.js ensures great speed and performance. Also, it can support intense traffic of multiple short messages, or chatrooms when messages are displayed to many users at the same time. Secondly, the ability to process real-time flows are extremely good. Trello is a project management application that is rather popular with software development companies. This application was developed on the basis of Node.js and benefited from its event-driven, non-blocking model. Node.js is great for applications requiring immediate updates, such as various collaboration tools and online documentation suites. Lastly, Node.js is great for data streaming applications. It is critical for audio and video streaming applications. Netflix is an example of how Node.js is powerful in this environment. NodeJS can send large amounts of data in smaller packages instead of a single batch.

Why is it worth developing your project in Node.js?

node js benefits

First of all, using Node.js as your server technology gives your team a great boost that comes from using the same language on both the front-end and back-end. This means that your team is more efficient and cross-functional, which in turn leads to lower development costs. In addition to that, it is worth mentioning that JavaScript is the most popular programming language, so your application’s codebase will be easier to understand for more developers. You can also reuse and share the code between the front-end and back-end parts of your application, which speeds up the development process. On top of that, the Node.js community is constantly growing – the number of StackOverflow questions is steadily increasing, so the knowledge base for the technology is widely available. The fact that the whole Node.js technology stack is open-source and free is also great news. Finally, Node.js offers a great package manager, NPM and the amount of available open-source tools in NPM’s registry is massive and growing fast. These are just a few of the many advantages of Node.js that you should consider when choosing the technology for your next project.

Where Node.js technology can be used?

node js in web app development

Node.js can be used as a server-side web application. Node.js with ExpressJS can also be used to create classic web applications on the server-side. However, while possible, this request-response paradigm in which Node.js technology would be carrying around rendered HTML as not the most typical use-case. There are arguments to be made for and against this approach.

  • Pros:

If your application doesn’t have any CPU intensive computation, you can build it in Javascript top-to-bottom, even down to the database level if you use JSON storage Object DB like MongoDB. This eases development (including hiring) significantly.

Crawlers receive a fully-rendered HTML response, which is far more SEO-friendly than, say, a Single Page Application or a WebSocket app run on top of Node.js.

  • Cons:

Any CPU intensive computation will block Node.js responsiveness, so a threaded platform is a better approach. Alternatively, you could try scaling out the computation.

Using Node.js with a relational database is still quite a pain. Do yourself a favour and pick up any other environment like Rails, Django, or ASP.Net MVC if you’re trying to perform relational operations.

Conclusion

Overall, Node.js development services can be involved in any business sphere with a couple of exceptions mentioned above. Over the last few years, it rapidly advanced from a specific solution for runtime communications to a full-fledged back-end technology with a number of powerful high-level frameworks (e.g. Express, Koa, Next or Nuxt). This evolution made it even more attractive for businesses and any Node.js development company there is; software developers speak highly of it. And if you would like to know what companies are using Node.js in production, the list will be impressive, including such giants as PayPal, Netflix, Uber, LinkedIn, eBay, Walmart, Medium, NASA, Mozilla, and Trello.

Savvycom uses Node.js technology to touch the techniques of the future

At Savvycom, we use Node.js to stay updated with the latest technologies. Also, by using Node.js we can satisfy our great customers. There are some applications that we have developed applying Node.js technology such as Milky Chat and Shopping App.

milky chat, an app using nodejs by savvycom

Have you ever thought what your child is doing at kindergarten? Milky Chat is a communication platform for parents to connect with kindergarten teachers to get the latest images and information about their kids. Teachers use the mobile app to take photos, add notes and information about the kids in their classes such as how many diapers/clothes changed or how much water/milk drunk. Once there are new activities of the kids, their parents got notified on the mobile so that they can open the app to view and interact.

Why choose .Net development over other platforms?

If you’re looking for an established method of running applications on both mobile and desktop platforms, ASP.NET and .Net development could bring your project in focus. With multiple frameworks to choose from that all work with each other seamlessly, your imagination is the limit. Running your website or mobile application using .Net software development gives you resources other systems don’t. With a wide range of coding and knowledge repositories, as well as server side compatibility, .Net development could be the way to go for your next venture.

Feel Secure with .Net Development

secure with net development by savvycom

There are many systems in place to build web applications, but Microsoft is an obviously well-established software developer and has decades of experience. With most of their now open source code available to all, developers worldwide have been able to take advantage of the standardization and cross-platform framework that .Net development provides. Additionally, their combined knowledge has helped evolve .Net into what it is today. As one of Savvycom’s software development strengths, we would love to share with you our real-world experience in these frameworks.

Organization and Cross-Platform Compatibility

net technology opt for crossplatform app based by savvycom

Computers and the World Wide Web are not the only fields which benefit from the same type of organization. If there weren’t any standards for automotive parts, batteries and tires would be proprietary to the maker. Speakers wouldn’t be interchangeable. Safety standards would wildly vary, as would the inventory in parts stores. With the advent of a framework with which factories knew they could produce certain items, it became faster and more cost-effective to follow a set of rules when it came to building what otherwise is a completely unique vehicle. This also reduces inventory on the shelf of the stores. For years, it was possible to use the starter from a Chevy Truck in any number of Chevrolet cars and some other brands owned by GM as well. They did this to save cost and boost efficiency. This is why you are considering .Net web development. You want a standardized web platform that has extensive compatibility capabilities with enormous potential.

So what would happen if programming had evolved to the point to where every single language was proprietary? Well, compare it to actual human speech. There are hundreds of languages, and most of them are so dissimilar that it takes years of study to become fluent in them if you ever can. But what if someone from a remote, small jungle type country in South America could use Google to translate content he or she might want to see? Google has created a framework of sorts where almost anyone of any language can consume content from any other country on the planet. This allows communication that never before might have happened, had there not been a common ground for everyone to contribute to.

The Logical Thing to Do

This is all an analogy of the type of challenges faced by programmers and companies trying to create applications on multiple platforms. In the beginning, everyone had to scramble to find resources. While we definitely encourage people to read books, it can be frustrating piling through documentation looking for a way to make your code compatible with every platform that exists. While we would like to say that manufacturers and computer languages have always had some sort of standard architecture, they really haven’t. Therefore, something was needed to help organize everything and create that standard. When it comes to web development, .Net was happy to step in.

microsoft dot net platform by savvycom

Microsoft developed .Net with the aim to standardize application compatibility on all browsers and all hardware connected to the web. This framework allowed the cross coding of several languages and frameworks, giving .Net developers a key to creating web and desktop content that was highly compatible across all platforms.

Why is .Net development outsourcing your best choice?

So, you’ve already decided that you want your project to take advantage of .Net development. You’ve considered operating the project in-house, but the costs of hiring a new .Net software developer that you don’t know is risky, and a team is out of the question. You’re trying to minimize liability for time lost and keep the bankers happy. What to do? .Net development outsourcing is the way to go. Time is money, and it’s best to have a team of skilled .Net developers on your side. Just as Microsoft grabbed an opportunity when they saw one, so has Savvycom. We specialize in all of the following fields;

  • Customised .Net Software development
  • Specialized, Customer Oriented .Net Development Outsourcing
  • Universally Compatible .Net Application Development
  • Team Oriented .Net Web Development
  • Customised .Net Web Application Development
  • Customised Asp.Net Web Development
  • Last but not least, Compatibility Focused Server Side Asp.Net Web Application Development

At Savvycom, we carried out a project of creating a social network measurement based on .Net platform. With the composition of web application frameworks such as C#, ASP.Net, ADO.Net, Web/Win services, we created a web application which gives marketers the knowledge of their community in the form of social profiles (LinkedIn, Facebook, Twitter, …). It analyses the communities participate and interact with the brand and its marketing messages. This knowledge gives marketers and community managers the tool to deliver more relevant and valuable product and information for their community.
