Documentation

• Our Express Quickstart is the quickest way to get up and running from scratch.
• Use the Examples for common configurations for use cases beyond the basics.
• The API documentation details all configuration options, methods, and data that this library provides.
• You can run the sample application to see how this SDK functions without writing your own integration.

Installation

This library is installed with npm:

npm i express-openid-connect --save

Getting Started

The library needs the following values to request and accept authentication:

• Issuer Base URL: The base URL of the authorization server. If you're using Auth0, this is your tenant Domain pre-pended with https:// (like https://tenant.auth0.com) found on the Settings tab for your Application in the Auth0 dashboard.
• Client ID: The identifier for your Application. If you're using Auth0, this value can also be found on the Settings tab for your Application.
• Base URL: The root URL for your application.

These can be configured in a .env file in the root of your application:

# .env

ISSUER_BASE_URL=https://YOUR_DOMAIN
CLIENT_ID=YOUR_CLIENT_ID
BASE_URL=https://YOUR_APPLICATION_ROOT_URL

... or in the library initialization:

// index.js

app.use(auth({
  required: true,
  issuerBaseURL: 'https://YOUR_DOMAIN',
  baseURL: 'https://YOUR_APPLICATION_ROOT_URL',
  clientID: 'YOUR_CLIENT_ID'
}));

See Examples for how to get started authenticating users.

What is Auth0?

Auth0 helps you to easily:

• implement authentication with multiple identity providers, including social (e.g., Google, Facebook, Microsoft, LinkedIn, GitHub, Twitter, etc), or enterprise (e.g., Windows Azure AD, Google Apps, Active Directory, ADFS, SAML, etc.)
• log in users with username/password databases, passwordless, or multi-factor authentication
• link multiple user accounts together
• generate signed JSON Web Tokens to authorize your API calls and flow the user identity securely
• access demographics and analytics detailing how, when, and where users are logging in
• enrich user profiles from other data sources using customizable JavaScript rules
