Fast, unopinionated, minimalist web framework for node.
var express = require('express');
var app = express();
app.get('/', function(req, res){
res.send('Hello World');
});
app.listen(3000);
$ npm install -g express
The quickest way to get started with express is to utilize the executable express(1) to generate an application as shown below:
Create the app:
$ npm install -g express
$ express /tmp/foo && cd /tmp/foo
Install dependencies:
$ npm install
Start the server:
$ node app
The Express philosophy is to provide small, robust tooling for HTTP servers, making it a great solution for single page applications, web sites, hybrids, or public HTTP APIs.
Built on Connect, you can use only what you need, and nothing more. Applications can be as big or as small as you like, even a single file. Express does not force you to use any specific ORM or template engine. With support for over 14 template engines via Consolidate.js, you can quickly craft your perfect framework.
Clone the Express repo, then install the dev dependencies to install all the example / test suite dependencies:
$ git clone git://github.com/strongloop/express.git --depth 1
$ cd express
$ npm install
Then run whichever tests you want:
$ node examples/content-negotiation
You can also view live examples here:
To run the test suite, first invoke the following command within the repo, installing the development dependencies:
$ npm install
Then run the tests:
$ npm test

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. Koa uses async functions to eliminate callback hell and simplify error handling. It does not bundle any middleware within its core, and it provides an elegant suite of methods that make writing servers fast and enjoyable.
Hapi is a rich framework for building applications and services. It enables developers to focus on writing reusable application logic instead of spending time building infrastructure. Hapi is known for its powerful plugin system and comprehensive API. Compared to Express, Hapi has a more rigid and structured approach, which can be beneficial for larger teams and projects.
Fastify is a web framework highly focused on providing the best performance out of the box. It is inspired by Express and Hapi but is built with a focus on speed and low overhead. Fastify is designed to be as fast as possible, and it achieves this by leveraging Node.js features and asynchronous patterns.
Sails.js is a modern MVC framework for Node.js that is built on top of Express. It is designed to emulate the familiar MVC pattern of frameworks like Ruby on Rails but with support for the requirements of modern apps: data-driven APIs with scalable, service-oriented architecture. Sails is especially good for building data-heavy enterprise-grade apps.
