How to use the config service to configure other modules?

Great library, but I’m having issues using the ConfigService to configure other modules. Can you provide some example?

For anyone here from google like me this is what I needed:

Documentation: https://docs.nestjs.com/techniques/mongodb#async-configuration

@Module({
  imports: [
    MongooseModule.forRootAsync({
      imports: [ConfigModule],
      useFactory: async (configService: ConfigService) => ({
        uri: configService.get<string>('MONGODB_URI'),
      }),
      inject: [ConfigService],
    }),
  ],
})
export class AppModule {}

… that requires the configservice to be passed in rather than loaded within the module itself therefore loading the config before all modules

I was thinking about the a few days ago. Ugly solution IMHO.

I hope that the issue on nestjs will be solved. In the end, it’s all about modules depending on services (@marcus-sa solution):

@Module({
  imports: [{
    useModule: (config: ConfigService) => MongooseModule.forRoot(config.mongoUri),
    inject: [ConfigService]
  }],
  providers: [ConfigService],
})
export class AppModule { }
