NestJS + Auth0 = ❤️

Description

A template for using Auth0 with the Nest framework. To start, either fork this repository or run

$ git clone --depth 1 https://github.com/jajaperson/nestjs-auth0.git

Setup

You'll need to populate a .env file with Auth0 configuration environemt details. This file should never be committed for obvious reasons (hence the reason it's .gitignore-d).

AUTH0_DOMAIN={your Auth0 domain}
AUTH0_CLIENT_ID={the Auth0 client ID for your app}
AUTH0_CLIENT_SECRET={the Auth0 client secret for your app}
AUTH0_AUDIENCE={http://localhost:3000 or your production domain accordingly}

A template .env file can be found at .env.example.

You may also like to remove all the irrelevant metadata from the package.json, suck as the repository, homepage, bugs, and description fields.

Explanation

Authentication logic

This template nest app uses the jwks-rsa package along with passport-jwt and @nestjs/passport for authentication. All authentication logic is in the /src/auth/ submodule.

src/auth/
├── auth.module.ts
├── interfaces
│   └── jwt-payload.interface.ts
├── jwt.strategy.spec.ts
└── jwt.strategy.ts

The JwtStrategy injectable contains all the core functionality, where the constructor sets up core token validation using the jwks-rsa library. All the Auth0 configuration for this is done in the .env file using @nestjs/config (see above). On any request with authentication, the decoded JSON web token (which should follow JwtPayload) is passed to the validate, which checks the token for the required scopes.

The AuthModule itself exports both PassportModule and the JwtStrategy injectable, and registers JwtStrategy as default.

AuthModule is imported by AppModule, and protected routes are decorated with @UseGuards(AuthGuard()) in AppController.
