oidc-provider

oidc-provider is an OpenID Provider implementation of OpenID Connect. It allows to export a complete mountable or standalone OpenID Provider implementation. This implementation does not dictate a fixed data model or persistence store, instead, you must provide adapters for these. A generic in-memory adapter is available to get you started as well as feature-less dev-only views to be able to get off the ground.

NOTICE: oidc-provider ^4.0.0 drops support for Node.js versions less than lts/carbon(8.9.0) and introduces various breaking changes. See the CHANGELOG for a complete list of deprecations and changes.

The following drafts/experimental specifications are implemented by oidc-provider.

• OpenID Connect Session Management 1.0 - draft 28
• OpenID Connect Back-Channel Logout 1.0 - draft 04
• OpenID Connect Front-Channel Logout 1.0 - draft 02

Certification

Filip Skokan has certified that oidc-provider conforms to the OP Basic, OP Implicit, OP Hybrid, OP Config, OP Dynamic and OP Form Post profiles of the OpenID Connect™ protocol.

If you want to quickly add OpenID Connect authentication to Node.js apps, feel free to check out Auth0's Node.js SDK and free plan at auth0.com/overview.

Get started

You may follow an example step by step setup (recommended), or run and experiment with an example server that's part of the repo (if you can follow the structure, if not check the step by step).

The example bundled in this repo's codebase is available for you to experiment with here. Dynamic Registration is open, you can literally register any client you want there.
An example client using this provider is available here (uses openid-client).

Configuration and Initialization

oidc-provider allows to be extended and configured in various ways to fit a variety of uses. See the available configuration.

const Provider = require('oidc-provider');
const configuration = {
  // ... see available options /docs/configuration.md
};
const clients = [{
  client_id: 'foo',
  client_secret: 'bar',
  redirect_uris: ['http://lvh.me:8080/cb'],
  // + other client properties
}];

const oidc = new Provider('http://localhost:3000', configuration);

(async () => {
  await oidc.initialize({ clients });
  // oidc.callback => express/nodejs style application callback (req, res)
  // oidc.app => koa2.x application
  oidc.listen(3000);
  console.log('oidc-provider listening on port 3000, check http://localhost:3000/.well-known/openid-configuration');
})().catch((err) => {
  console.error(err);
  process.exitCode = 1;
});

Debugging

oidc-provider uses the debug module internally to log information about various states of authentication requests, errors and grants. To see all these set the DEBUG environment variable to oidc-provider:* when launching your app.

There is no filter on what is included in the debug output, since it may end-user Personally identifiable information or client credentials it's use is only advised for debugging, not regular logging. Use emitted events to cherry pick the one's of interest to your flows and form your own logs aware of what should and should not be a part of a logged message.

Events

Your oidc-provider instance is an event emitter, using event handlers you can hook into the various actions and i.e. emit metrics or that react to specific triggers. In some scenarios you can even change the defined behavior.
See the list of available emitted event names and their description.
