In this article, we will see how to expire the session after 1 min of inactivity in express-session of Express.js.
Prerequisites
- Installation of Node.js on Windows
- To set up Node Project in Editor see here.
Requires Modules:
npm install express npm install express-session
Call API:
var session = require('express-session')
To expire the session after 1 min of inactivity in the express-session of Express.js we use expires: 60000 in the middleware function.
Project Structure:
The below example illustrates the above approach:
Example:
Filename: app.js
// Call Express Api. const express = require( 'express' ),
// Call express Session Api.
session = require( 'express-session' ),
app = express();
// Session Setup app.use( session({
// It holds the secret key for session
secret: "I am girl" ,
// Forces the session to be saved
// back to the session store
resave: true ,
// Forces a session that is "uninitialized"
// to be saved to the store
saveUninitialized: false ,
cookie: {
// Session expires after 1 min of inactivity.
expires: 60000
}
})
); // Get function in which send session as routes. app.get( '/session' , function (req, res, next) {
if (req.session.views) {
// Increment the number of views.
req.session.views++
// Session will expires after 1 min
// of in activity
res.write(
' <p> Session expires after 1 min of in activity: ' + (req.session.cookie.expires) + '</p>
' )
res.end()
} else {
req.session.views = 1
res.end( ' New session is started' )
}
}) // The server object listens on port 3000. app.listen(3000, function () {
console.log( "Express Started on Port 3000" );
}); |
Steps to run the program:
Run the index.js file using the below command:
node app.js
Now to set your session, just open the browser and type this URL :
http://localhost:3000/session
Output: After 1 min of inactivity it will start the new session, old session is expired.
