To make our development process a lot easier, we will install a tool from npm, nodemon. This tool restarts our server as soon as we make a change in any of our files, otherwise we need to restart the server manually after each file modification. To install nodemon, use the following command − ... Once express set up is complete, we can start developing our first app using Express.

Single page apps: Node.js is an excellent choice for SPAs because of its capability to efficiently handle asynchronous calls and heavy input/output(I/O) workloads. Data driven SPAs built with Express.js are fast, efficient and robust.

const http = require('http'); const express = require('express'); const bodyParser = require('body-parser'); const app = express(); app.use(bodyParser.urlencoded({extended: false})); the use(0 function shown above uses next() function by default so http request gets passed to next middleware without any trouble. The above parser is useful for parsing simple form data like input text etc. but for parsing files, json we will use different parsers.

express.text() is a built-in middleware function in Express. It parses the incoming request payloads into a string and it is based upon the body-parser. This method returns the middleware that parses all the bodies as strings.

Node.jsServer Side ProgrammingProgramming · For handling different routes, use() function is used. use() function has multiple overloaded version, one of version also takes url path as a argument. Based on the url path, the requests will be filtered out for respective middleware. const http = require('http'); const express = require('express'); const app = express(); app.use('/', (req, res,next)=>{ console.log('first middleware'); res.send('<h1> first midleware: Hello Tutorials Point </h1>'); }); const server = http.createServer(app); server.listen(3000); in above example we used ‘/’ as url path, it’s a default.

In this first Express article we answer the questions "What is Node?" and "What is Express?", and give you an overview of what makes the Express web framework special. We'll outline the main features, and show you some of the main building blocks of an Express application (although at this point you won't yet have a development environment in which to test it).
