@bull-board/nestjs

NestJS for bull-board.

Installation

Install both @bull-board/api and this module.

$ npm install --save @bull-board/nestjs @bull-board/api

Install the Express or Fastify adapter depending on what you use in NestJS (default is Express)

$ npm install --save @bull-board/express
//or 
$ npm install --save @bull-board/fastify

Register the root module

Once the installation is completed, we can import the BullBoardModule into your rootmodule e.g. AppModule.

import { Module } from '@nestjs/common';
import { BullBoardModule } from "@bull-board/nestjs";
import { ExpressAdapter } from "@bull-board/express";

@Module({
  imports: [
    BullModule.forRoot({
      // your bull module config here.
    }),

    BullBoardModule.forRoot({
      route: '/queues',
      adapter: ExpressAdapter // Or FastifyAdapter from `@bull-board/fastify`
    }),
  ],
})
export class AppModule {
}

The forRoot() method registers the bull-board instance and allows you to pass several options to both the instance and module. The following options are available.

route the base route for the bull-board instance adapter.
adapter The routing adapter to be used, either the Express Adapter or Fastify Adapter provided by bull-board.
boardOptions options as provided by the bull-board package, such as uiBasePath and uiConfig
middleware optional middleware for the express adapter (e.g. basic authentication)

Register your queues

To register a new queue, you need to register BullBoardModule.forFeature in the same module as where your queues are registered.

import { Module } from '@nestjs/common';
import { BullBoardModule } from "@bull-board/nestjs";
import { BullModule } from "@nestjs/bullmq";

@Module({
  imports: [
    BullModule.registerQueue(
      {
        name: 'my_awesome_queue'
      }
    ),
    
    BullBoardModule.forFeature({
      name: 'my_awesome_queue',
      adapter: BullMQAdapter, //or use BullAdapter if you're using bull instead of bullMQ
    }),
  ],
})
export class FeatureModule {}

The forFeature method registers the given queues to the bull-board instance. The following options are available.

name the queue name to register
adapter either BullAdapter or BullMQAdapter depending on which package you use.
options queue adapter options as found in the bull-board package, such as readOnlyMode, description etc.

Using the bull-board instance in your controllers and/or services.

The created bull-board instance is available via the @InjectBullBoard() decorator. For example in a controller:

import { Controller, Get } from "@nestjs/common";
import { BullBoardInstance, InjectBullBoard } from "@bull-board/nestjs";

@Controller('my-feature')
export class FeatureController {

  constructor(
    @InjectBullBoard() private readonly boardInstance: BullBoardInstance
  ) {
  }
  
  //controller methods
}
