Description

oidc-provider module for Nest framework (node.js)

Installation

$ npm i --save nest-oidc-provider oidc-provider

OR

$ yarn add nest-oidc-provider oidc-provider

Setup

Basic configuration

@Module({
  imports: [
    OidcModule.forRoot({
      issuer: 'http://localhost:3000',
      path: '/oidc',
      oidc: ... // oidc-provider configuration
    })
  ],
})
export class AppModule {}

Custom factory function

You can pass a factory function to customize the provider instantiation.

@Module({
  imports: [
    OidcModule.forRoot({
      issuer: 'http://localhost:3000',
      path: '/oidc',
      factory: (issuer, config) => {
        const provider = new oidc.Provider(issuer, config);
        provider.on('server_error', (ctx, err) => {...})
        return provider;
      },
      oidc: ... // oidc-provider configuration
    })
  ],
})
export class AppModule {}

Trusting TLS offloading proxies

You can set the proxy option to true to trust TLS offloading proxies.
For more info visit the oidc-provider documentation: Trusting TLS offloading proxies

@Module({
  imports: [
    OidcModule.forRoot({
      issuer: 'http://localhost:3000',
      path: '/oidc',
      proxy: true, // <= trust TLS offloading proxies
      oidc: {...}
    })
  ],
})
export class AppModule {}

Async configuration

useFactory

@Module({
  imports: [
    OidcModule.forRootAsync({
      imports: [ConfigModule],
      useFactory: async (configService: ConfigService) => ({
        issuer: configService.get<string>('ISSUER'),
        path: configService.get<string>('OIDC_PATH'),
        oidc: ... // oidc-provider configuration
      }),
      inject: [ConfigService],
    }),
  ],
})
export class AppModule {}

useClass

@Module({
  imports: [
    OidcModule.forRootAsync({
      useClass: OidcConfigService,
    }),
  ],
})
export class AppModule {}

Note that in this example, the OidcConfigService has to implement the OidcModuleOptionsFactory interface, as shown below.

@Injectable()
export class OidcConfigService implements OidcModuleOptionsFactory {
  constructor(private readonly @InjectConnection() conn: Connection) {}

  createModuleOptions(): OidcModuleOptions {
    return {
      issuer: 'http://localhost:3001',
      path: '/oidc',
      oidc: ..., // oidc-provider configuration
    };
  }

  createAdapterFactory?(): AdapterFactory {
    return (modelName: string) => new MyAdapter(modelName, this.conn);
  }
}

You can omit the Adapter option of oidc-provider configuration if you implement the createAdapterFactory method.

useExisting

@Module({
  imports: [
    OidcModule.forRootAsync({
      imports: [OidcConfigModule],
      useExisting: OidcConfigService,
    }),
  ],
})
export class AppModule {}

Custom param decorators

@Oidc.Interaction()

Returns an instance of InteractionHelper class.

@Get(':uid')
@Render('login')
async login(
  @Oidc.Interaction() interaction: InteractionHelper
) {
  const { prompt, params, uid } = await interaction.details();

  const client = await this.provider.Client.find(params.client_id as string);

  return { prompt, client, params, uid, ...};
}

The InteractionHelper class is just a helper that omits the req and res parameters from the existing interaction methods in oidc-provider.

interface InteractionHelper {
  details(): Promise<InteractionDetails>;

  finished(
    result: InteractionResults,
    options?: { mergeWithLastSubmission?: boolean },
  ): Promise<void>;

  result(
    result: InteractionResults,
    options?: { mergeWithLastSubmission?: boolean },
  ): Promise<string>;
}

@Oidc.Context()

Returns an instance of KoaContextWithOIDC.

@Get()
async index(@Oidc.Context() ctx: KoaContextWithOIDC) {
  const { oidc: { provider } } = ctx;
  const session = await provider.Session.get(ctx);
  //...
}
