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.

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 or your business use oidc-provider, please consider becoming a Patron so I can continue maintaining it and adding new features carefree. You may also donate one-time via PayPal.

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

The examples bundled in this repo's codebase are available for you to experiment with . 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).

Also be sure to check the available configuration docs section.

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);

let server;
(async () => {
  await oidc.initialize({ clients });
  // 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
  server = oidc.listen(3000, () => {
    console.log('oidc-provider listening on port 3000, check http://localhost:3000/.well-known/openid-configuration');
  });
})().catch((err) => {
  if (server && server.listening) server.close();
  console.error(err);
  process.exitCode = 1;
});

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.

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.
