Auth0

To enable OAuth logins with Auth0, we need the following settings after creating an application:

This should be added in your configuration (usually config/default.json) as follows:

"authentication": {
  "oauth": {
    "redirect": "/",
    "auth0": {
      "key": "<Client ID>",
      "secret": "<Client Secret>",
      "subdomain": "<Domain without auth0.com",
      "scope": ["openid", "profile", "email"]
    }
  }
}

Important: subdomain should be the "Domain" from the application settings without the auth0.com part. So, in the screenshot above, the subdomain for dev-6gqkmpt6.auth0.com would be dev-6gqkmpt6. If the subdomain includes a region, it needs to be included as well so the subdomain for dev-6gqkmpt6.us.auth0.com would be dev-6gqkmpt6.us

Strategy

To use Auth0 in the chat application from the Feathers guide we have to do the same modifications as already shown for the GitHub login in the authentication guide.

In src/authentication.ts like this:

import { ServiceAddons, Params } from '@feathersjs/feathers';
import { AuthenticationService, JWTStrategy } from '@feathersjs/authentication';
import { LocalStrategy } from '@feathersjs/authentication-local';
import { expressOauth, OAuthStrategy, OAuthProfile } from '@feathersjs/authentication-oauth';

import { Application } from './declarations';

declare module './declarations' {
  interface ServiceTypes {
    'authentication': AuthenticationService & ServiceAddons<any>;
  }
}

class Auth0Strategy extends OAuthStrategy {
  async getEntityData(profile: OAuthProfile, existing: any, params: Params) {
    const baseData = await super.getEntityData(profile, existing, params);

    return {
      ...baseData,
      email: profile.email
    };
  }
}

export default function(app: Application) {
  const authentication = new AuthenticationService(app);

  authentication.register('jwt', new JWTStrategy());
  authentication.register('local', new LocalStrategy());
  authentication.register('auth0', new Auth0Strategy());

  app.use('/authentication', authentication);
  app.configure(expressOauth());
}

In src/authentication.js like this:

const { AuthenticationService, JWTStrategy } = require('@feathersjs/authentication');
const { LocalStrategy } = require('@feathersjs/authentication-local');
const { expressOauth, OAuthStrategy } = require('@feathersjs/authentication-oauth');

class Auth0Strategy extends OAuthStrategy {
  async getEntityData(profile) {
    const baseData = await super.getEntityData(profile);

    return {
      ...baseData,
      email: profile.email
    };
  }
}

module.exports = app => {
  const authentication = new AuthenticationService(app);

  authentication.register('jwt', new JWTStrategy());
  authentication.register('local', new LocalStrategy());
  authentication.register('auth0', new Auth0Strategy());

  app.use('/authentication', authentication);
  app.configure(expressOauth());
};

Additionally, auth0Id needs to be included in the data in the users service class.
