5. Wire the module

// backend/src/tasks/tasks.module.ts
import { Module } from '@nestjs/common';

import { AuthModule } from 'src/auth/auth.module';
import { TasksController } from './tasks.controller';
import { TasksService } from './tasks.service';

@Module({
  imports: [AuthModule],
  controllers: [TasksController],
  providers: [TasksService],
  exports: [TasksService],
})
export class TasksModule {}

KNEX_CONNECTION is provided globally by KnexModule, so no extra imports are needed for data access.

Register in the root module:

// backend/src/app.module.ts
import { TasksModule } from './tasks/tasks.module';

@Module({
  imports: [
    // ... existing modules ...
    TasksModule,
  ],
})
export class AppModule {}
