Middleware that validates JsonWebTokens and set req.user.

This module lets you authenticate HTTP requests using JWT tokens, in your Node.js applications. JWT tokens are typically used protect API endpoints, and are often issued using OpenID Connect.


$ npm install express-jwt


The JWT authentication middleware authenticates callers using a JWT token. If the token is valid, req.user will be set with the JSON object decoded to be used by later middleware for authorization and access control.

For example,

var jwt = require('express-jwt');

  jwt({secret: 'shhhhhhared-secret'}),
  function(req, res) {
    if (!req.user.admin) return res.send(401);

You can specify audience and/or issuer as well

jwt({ secret: 'shhhhhhared-secret',
      audience: 'http://myapi/protected',
      issuer: 'http://issuer' })

If the JWT has an expiration (exp), it will be checked.

Optionally you can add paths for the middleware to skip

app.use(jwt({ secret: 'shhhhhhared-secret', skip: ['/token']}));

This is especially useful when applying to multiple routes.

This module also support tokens signed with public/private key pairs. Instead of a secret, you can specify a Buffer with the public key

var publicKey = fs.readFileSync('/pat/to/');
jwt({ secret: publicKey });
