: Ports are the endpoints of communication which helps to communicate with the client and the server.. IP : IPs represent IPv4 or IPv6 address of a host or a device.. Callback : It accepts a function.. Koa does not use callbacks hence facilitating upstream and downstream flow of controls. Let’s see a code example. This article will give a comparison between the three major Node.js frameworks, Express, Hapi, and Koa. It is the most important thing to take best practices to have a better performance in Node.Js to run all the things parallel, you can use asynchronous API in your code and keep your code small and lightweight also you can use gzip compression. Koa is a more evolved form of Express whose main feature is the elimination of callbacks. Koa has a small footprint (about 600 lines of code) therefore making it very light weight. koa vs express. Koa concentrates its efforts on core middleware functionality. The most important reason people chose Express.js is: Express' extremely powerful routing API allows developers to do tasks ranging from building a REST API to building the routes for a simple web app and then take it to the next level by using route parameters and query strings. It can contain many helpful methods and functions and that is too lightweight and it does not bundle any middleware which can allow you to customize. Then use its listen method to start a server at a certain port. "Setting up is very easy" is the primary reason people pick Express.js over the competition. In Hapi, we import the hapi module, then, instead of instantiating the module, we use its server method to create a server by passing an object containing the port and host name. Express VPN constantly causes me to lose my internet connection on my Dell XPS Laptop, Windows 10 especially when booting the computer or waking the computer. Koa eases code management process, is lightweight, and makes use of asynchronous API’s in the code, keeping the code small, light, making use of GZip compression. However, he's speaking specifically to the middleware framework. Express. The framework was built by the team behind express with the aim of making it smaller, more expressive, and robust. Express. It is easy to integrate third party services and middleware. We have gone through their histories, popularity, advantages and disadvantages, performance and created a server with each one. As well as it can make the code management systems easier. Koa uses promises and async functions to rid apps of callback hell and simplify error handling. Hapi framework has a unique feature that is the ability to create a server on a different IP with features like OnPreHandler. The main reason that Koa got any real traction was during a period when Express wasn't receiving regular updates, and there were some ownership issues. Express is closer to Node. With that, a developer can now choose the framework which best satisfies his/her needs for their application. Refer to my introduction to Hapi.js framework for a detailed look at Hapi.js. Hapi.js’s GitHub repository has 12.7k stars, 205 contributors, 1.3k forks, and 332 releases. The two main contributors at the time of its first release were TJ Holowaychuk and Ciaron Jessup. The Express framework is the oldest of the three. From our performance test, we saw that Koa performs the best since it can handle more requests per second. Here we compare between connect, express, fastify, hapi and koa.In this comparison we will focus on the latest versions of those packages. Express.js, Koa, and NestJS are probably your best bets out of the 5 options considered. Hapi’s initial commit was made on August 5th, 2011 and after 5,619 commits, it is currently at version 20.0.0. Express requires a lot of manual labor since endpoints, middleware, etc. Use a load balancer to run multiple instances.

For more background on the frameworks, check out the following articles to get a more in depth look before we begin: Before we start our in-depth comparison of each framework, let’s take a look at how they got started. Topics: Node.js; Node.js has various frameworks, each of which is catered to the varying demands of users and developers. Philosophically, Koa aims to "fix and replace node", whereas Express "augments node". The reality is, both of these frameworks are used to glue together middleware, which does the actual work (body parsers, etc.). How Koa Compares to Express. Koa is not compatible with Express style middleware. app.listen(PORT, IP, Callback); Parameter: This method accepts three parameters as mentioned above and described below: PORT : Ports are the endpoints of communication which helps to communicate with the client and the server.. IP : IPs represent IPv4 or IPv6 address of a host or a device.. Callback : It accepts a function.. Koa does not use callbacks hence facilitating upstream and downstream flow of controls. Let’s see a code example. This article will give a comparison between the three major Node.js frameworks, Express, Hapi, and Koa. It is the most important thing to take best practices to have a better performance in Node.Js to run all the things parallel, you can use asynchronous API in your code and keep your code small and lightweight also you can use gzip compression.
