Express.js boilerplate cheatsheet

islamabad50 profile image -FA ・1 min read

This is the bare minimum cheatsheet to get express.js up and running.

  • Download and install node.js from https://nodejs.org/en/download/
  • Open terminal or commandline
  • Creat a project directory and change to it
  • Run terminal command: npm init (accept all defaults by pressing enter)
    • This will create package.json file, which has basic project configuration
  • Run terminal command: npm i express
    • This installs express.js
  • Run terminal command: npm i -g nodemon
    • Installs node monitor, which will make sure server is restared on file saves
  • Create new file index.js (which is referenced in the package.json file created above)
  • Add the following starter code to index.js, which is the bare minimum to get it going:
    const express = require('express')
    const app = express()
    const port = 3000

    app.get('/', (req, res) => res.send('Hello World!'))

    app.listen(port, () => console.log(`Example app listening on port ${port}!`))
  • Run terminal command: node index.js to run it
  • or run terminal command: nodemon index.js to run it via nodemon - this will ensure that server is restarted automatically whenever there is a file change
  • Open localhost:3000 to view in browser - should show: Hello World!
