    express-aad-jwt

    Build

    Middleware that validates JsonWebTokens issued from Azure Active Directory and sets req.user.

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

    Install

    $ npm install express-aad-jwt
    

    Usage

    The JWT authentication middleware authenticates callers using a JWT. 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-aad-jwt');
     
    app.get('/protected',
      jwt(),
      function(req, res) {
        if (!req.user.admin) return res.send(401);
        res.send(200);
      });

    You can specify audience as well:

    jwt(audience: 'https://graph.windows.net'})

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

    Optionally you can make some paths unprotected as follows:

    app.use(jwt().unless({path: ['/token']}));

    This is especially useful when applying to multiple routes.

    By default, the decoded token is attached to req.user but can be configured with the requestProperty option.

    jwt({ requestProperty: 'auth' });

    Error handling

    The default behavior is to throw an error when the token is invalid, so you can add your custom logic to manage unauthorized access as follows:

    app.use(function (err, req, res, next) {
      if (err.name === 'UnauthorizedError') {
        res.send(401, 'invalid token...');
      }
    });

    You might want to use this module to identify registered users without preventing unregistered clients to access to some data, you can do it using the option credentialsRequired:

    app.use(jwt({
      credentialsRequired: false
    }));
