nestjs-dynamic-queue v0.1.0

Introduction

The nestjs-dynamic-queue package is a NestJS module that allows you to create queues at runtime and send messages to them. It provides a wrapper around the bull package, which is a powerful Redis-based queue library. With nestjs-dynamic-queue, you can easily integrate queue functionality into your NestJS application and leverage the features provided by bull, such as job scheduling, retries, and prioritization.

Installation

yarn add nestjs-dynamic-queue

or

npm i nestjs-dynamic-queue

Usage

Importing module Async

import { DynamicQueueModule, DynamicQueueConnectOptions } from 'nestjs-dynamic-queue';
@Module({
  imports: [
		DynamicQueueModule.forRootAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: async (configService): Promise<DynamicQueueConnectOptions> => ({
				queueNamePrefix: 'prefix',
				redis: {
					host: configService.get('REDIS_HOST'),
					port: configService.get('REDIS_PORT'),
					password: configService.get('REDIS_PASSWORD'),
				},
				defaultJobOptions: {
					attempts: 4,
				},
				initialQueueNames: ['someInitialQueue'],
			})
		})
  ],
  providers: [],
  exports: [],

Add queue and create task

import { DynamicQueueService } from 'nestjs-dynamic-queue';

@Injectable()
export class YourService {
  constructor(private dynamicQueueService: DynamicQueueService) {}

	async method() {
		await this.dynamicQueueService.addTask('queue', 'type task', payload);
    return;
	}
}

Create processor and processes

import { Processor, Process } from from 'nestjs-dynamic-queue';

@Processor()
export class WebhookProcessor {
  constructor(private readonly yourService: YourService) {}

  @Process({ name: 'type task', concurrency: 1 })
