Express.js - add cookie

In this short article, we would like to add cookie in Express.js.

1. Install cookie-parser package:

xxxxxxxxxx

npm install cookie-parser

2. Use response.cookie() method to add cookies with specified cookie name and value.

In this example, we use response.cookie() method to create username cookie wich stores john value.

xxxxxxxxxx

const express = require('express')

const cookieParser = require('cookie-parser')

const app = express()

​

app.use(cookieParser())

​

app.get('/', (request, response){

    response.cookie('username', 'john').send('Cookie set');  // username=john

});

​

app.listen(3000);

 After running the code and entering localhost:3000, we will see the window below.
