@mikilian/nest-rabbitmq v1.0.2

@mikilian/nest-rabbitmq

A wrapper of the AMQP library for NestJS to provide fast communication between services. The idea behind it is to provide possible ways of communication with a message system without having to write a lot of code.

Installation

Consider adding @types/amqplib as development dependency when using TypeScript

# using yarn
yarn install @mikilian/nest-rabbitmq

# using npm
npm install --save @mikilian/nest-rabbitmq

Usage

import { Module } from '@nestjs/common';
import { RabbitMQModule } from '@mikilian/nest-rabbitmq'

@Module({
    imports: [
        RabbitMQModule.forRoot({
            hostname: 'localhost',
            username: 'admin',
            password: 'pw'
        }),
    ]
})
export class AppModule {}

You can also use a factory to create the configuration file.

import { Module } from '@nestjs/common';
import { ConfigModule, ConfigService } from '@nestjs/config';
import { RabbitMQModule } from '@mikilian/nest-rabbitmq'

@Module({
    imports: [
        RabbitMQModule.forRootAsync({
            imports: [ConfigModule],
            useFactory: (config: ConfigService) => ({
                hostname: config.get('ENV_FOR_HOSTNAME') as string,
                username: config.get('ENV_FOR_USERNAME') as string,
                password: config.get('ENV_FOR_PASSWORD') as string,
            }),
            inject: [ConfigService]
        })
    ]
})
export class AppModule {}

Examples

To run the examples, a RabbitMQ server is required. Afterwards three environment variables are needed, so it is recommended to export them in the terminal.

export AMQP_HOSTNAME=''
export AMQP_USERNAME=''
export AMQP_PASSWORD=''

Now any example can be executed using yarn run example:<ID>. The code can be found in the examples directory.
