In this section we are going to highlight some of the advantages and disadvantages of each framework. Then once we call server.start() we start the server on port 3000 which then returns a callback. Hapi provides input/output validation, routing and caching, hence making it a good choice for building REST APIs. With more points in favor and in common, both frameworks share very few differences. Hapi.js handles 29,998 requests per second while Express handles 38,510 requests per second. The basic hello world app will look like this in koa: We import the Koa module, instantiate, store it in a variable, and then use its listen method to start the server. Koa framework can improve robustness and that can make writing middleware more enjoyable and better for all user experience. Express requires a lot of manual labor since endpoints, middleware, etc. Chalking out major differences: Express vs. Koa Hapi uses plugins which breaks applications in to smaller pieces thus helping with scaling. Node.js has various frameworks, each of which is catered to the varying demands of users and developers. Peer Review Contributions by: Louise Findlay. need to be created and tested manually. 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. It exposes its own ctx.request and ctx.response objects instead of node's req and res objects. Koa relies heavily on the use of middleware, while Micro doesn't. Express is somewhat less opinionated than Hapi, in the sense that it is less abstracted from Node. Here's a brief summary on how fastify overhead performed against the some other well known Node.js web frameworks: 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. Node.Js has first introduced 10 years ago, in this period Node.Js has become the fastest growing open source project on the earth, with +59000 stars on GitHub and the main reason is that it has a… Koa is built by the same team behind the Express, and it aims to be smaller and more expressive, and that is a more robust foundation for web applications and APIs. Koa is a pretty large departure from what people know about Express, the design is fundamentally much different, so the migration from Express 3.0 to this Express 4.0 would effectively mean rewriting the entire application, so we thought it would be more appropriate to create a new library. 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. Hapi’s initial commit was made on August 5th, 2011 and after 5,619 commits, it is currently at version 20.0.0. This was just because you can stop using callbacks, you can deal with errors faster, that is just because of Koa itself, a very lightweight framework. Hapi can enable developers to write reusable code in application logic instead of spending a lot of time to build infrastructure. Koa provides a Response object as the response property of the Context. Express is simple, flexible, and scalable. What is the Hype Around Hapi vs Express in 2020? Hey man, I'm relatively new to Node.js and I've built some small apps in Express.js and Koa.js. Node.Js has first introduced 10 years ago, in this period Node.Js has become the fastest growing open source project on the earth, with +59000 stars on GitHub and the main reason is that it has a… Express is also easy to test due to its middleware and routes that modularize projects. It was originally built using the Express framework before challenges arose that drove Walmart to make Hapi, its stand-alone framework.

In this comparison, we will look at the differences between the three frameworks, their histories, advantages and disadvantages, popularity, support and performance. We all know that Express can play a major role in MEAN stack development. Koa has a small footprint (about 600 lines of code) therefore making it very light weight. These routines are called before route handlers, so they live in the … Unlike Hapi, both Koa and Express use a similar logic to create a server. Koa is more lightweight and more modular than express. Then use its listen method to start a server at a certain port. Web development with node and express and Koa is built on a similar philosophy. If you are deciding between Koa and Express, ask these questions: Is it a greenfield application? Criterion #8:Popularity. 1. It is not compatible with Express middleware. Refer to my introduction to koa.js framework for a detailed look at Koa.js. In the question "What are the best Express.js alternatives?" Hapi provides a deeper control over request handling through the use of context. With that, a developer can now choose the framework which best satisfies his/her needs for their application. 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. Express.js is ranked 3rd while Meteor is ranked 36th. This page is powered by a knowledgeable community that helps you make an informed decision.

"Setting up is very easy" is the primary reason people pick Express.js over the competition. While KOA is more lightweight there are tons of additional modules that make it do everything Express can. 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. Here we compare between connect, express, fastify, hapi and koa.In this comparison we will focus on the latest versions of those packages. After reading all of the rave reviews, I signed up for ExpressVPN. How Koa Compares to Express. In this section, we will compare the frameworks based on the number of requests that a hello world server can handle in one second. Hapi has a wide variety of plugins that make it a little bit easier to build APIs with since almost every common task such as routing, logging, caching, and authentication etc. NodeJS middleware are routines that have access to the Request object (req) and Response object (res). Refactoring larger code bases is very challenging. Koa. Micro vs Koa vs Express I have only used Express & I can be quickly productive with Express, but Koa & Micro seems to be a good option. Koa.js was created to be better than Express, therefore, it can do all that Express can do and more. Peter Kayere is a first-year undergraduate student at Jomo Kenyatta University of Agriculture and Technology studying Computer Technology. 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.

When it comes to rivalry Koa and Express, both have their unique way of doing things. This article will give a comparison between the three major Node.js frameworks, Express, Hapi, and Koa. The reality is, both of these frameworks are used to glue together middleware, which does the actual work (body parsers, etc.). The framework was built by the team behind express with the aim of making it smaller, more expressive, and robust. Hapi is one rich framework to build applications and services. 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.. Below are some other points that would help when choosing the right framework for a project: In this article we have done a comparison of the three major Node.js frameworks. This page is powered by a knowledgeable community that helps you make an informed decision. These modules exist independently and can be incorporated later. Express is closer to Node. From our performance test, we saw that Koa performs the best since it can handle more requests per second. Express, by contrast, needs the body-parser middleware to offer the same functionality. OK So just like angular vs react it's about accepting an opinionated framework or not Nest is extremely opinionated and it forces an architecture which is legtiamte and solid. Therefore, you will see a lot of similarities in the way code is written in Express vs Koa.
