Auth0 Express Middleware

Express middleware to validate Javascript Web Tokens.

When building an API, it may be necessary to prevent unauthorized access. The easiest way to do this is to secure the API behind a third-party authentication system, such as Auth0.

Before you install

See Auth0's docs on creating a Server Application + API architecture. This document explains the OAuth2 workflow necessary for full-featured logins to a server-side application and JWT authentication on the API. This middleware is intended as a drop-in middleware for Express-based APIs.

Installing

$ npm install git+https://github.com/pantheon-systems/pantheon-auth0-express-middleware

Note that this package is NOT published on npm.org and must be installed using the git url.

API

var express = require('express');
var jwt = require('@pantheon-systems/auth0-express-middleware');

var app = express();
var router = express.Router();

router.use(jwt({
    domain: "<YOUR_AUTH0_DOMAIN>",
    audience: "<YOUR_AUTH0_AUDIENCE>"
}));

app.use('/', router);

In this example, all the JWT middleware is applied as a router middleware and is enforced for all routes in the application.

Options

The middleware function takes the following options:

Name	Description	Required?	Default
domain	The Auth0 domain from your configuration	Y	n/a
audience	The Auth0 audience from your configuration	Y	n/a
cache	Whether or not to cache the JWT	N	true
rateLimit	Whether or not to rate-limit JWT requests	N	true
rpm	The rate limit for new token requests, in seconds	N	12
