Create a basic web server using express js

September 25, 2021

Easiest way to create a basic webserver using express js.

We can use node js to create a web server using node js will a long time to create a server so we use express js for these types of thing.

First of all we are gonna create a new file named server.js or you can use any name you want.

Coding Time

const express = require("express") // npm install express
const app = express()
const port = 3000

// Send text
app.get("/", (req, res) => {
  res.send("Hello World!")
})

// Send HTML File
app.get("/", (req, res) => {
  res.sendFile("./index.html")
})

app.listen(port, () => {
  console.log(`Your app is listening to port ${port}`)
})

Now run your code but how? lemme tell you open terminal in visual studio code or or open command promt in your folder then write down these commands in terminal.

First command

npm install express

Second command

npm install --save-dev nodemon
# To run our code we use this package.

Last command

nodemon server.js
# make sure to replace server.js with your file name

And thats for this post see you in another one
