Get started

You may check the example folder or follow a step by step example to see which of those fits your desired application setup.

A feature-rich example configuration of oidc-provider is available for you to experiment with here. Dynamic Client Registration is open, you can literally register any client you want there. An example client using this provider is available here (uses openid-client).

Also be sure to check the available configuration docs section.

Documentation & Configuration

oidc-provider can be mounted to existing connect, express, fastify, hapi, or koa applications, see how. The provider allows to be extended and configured in various ways to fit a variety of uses. See the documentation.

const { Provider } = require('oidc-provider');
const configuration = {
  // ... see available options /docs
  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);

// express/nodejs style application callback (req, res, next) for use with express apps, see /examples/express.js
oidc.callback

// koa application for use with koa apps, see /examples/koa.js
oidc.app

// or just expose a server standalone, see /examples/standalone.js
const server = oidc.listen(3000, () => {
  console.log('oidc-provider listening on port 3000, check http://localhost:3000/.well-known/openid-configuration');
});

Recipes

Collection of useful configurations use cases are available over at recipes.

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 its 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.
