NestJS + TypeORM: Use two or more databases?

Question

I\'m trying since 2 days to solve this, perhaps I\'m simply missing the point here.

My goal was to write a NestJS app (with TypeORM included) which serves a RestAPI

You need to explicitly pass the connection name at the same level inside TypeOrmModule.forRoot({ name: 'db1Connection' }) incase you are using multiple database connections.

TypeOrmModule.forRootAsync({
  name: DB1_CONNECTION,
  imports: [ConfigModule],
  useClass: TypeormDb1ConfigService,
}),

TypeOrmModule.forRootAsync({
  name: DB2_CONNECTION,
  imports: [ConfigModule],
  useClass: TypeormDb2ConfigService,
})
