NestJS Azure Service Bus
A dynamic module for NestJS that provides integration with Azure Service Bus.
Installation
npm install nestjs-azure-service-bus
Description
The NestJS Azure Service Bus package allows you to easily integrate Azure Service Bus into your NestJS applications. It provides decorators for injecting Azure Service Bus senders and receivers, as well as a dynamic module for configuring the Azure Service Bus client.
Usage
AzureServiceBusModule - Importing the module
To use the Azure Service Bus module, import it into your NestJS application's root module:
import { Module } from '@nestjs/common';
import { AzureServiceBusModule } from 'nestjs-azure-service-bus';
@Module({
imports: [
AzureServiceBusModule.forRoot({
connectionString: '<your-connection-string>',
}),
],
})
export class AppModule {}
Replace <your-connection-string>
with your Azure Service Bus connection string.
AzureServiceBusModule - Injecting Senders and Receivers
You can use the Sender
and Receiver
decorators provided by the module to inject Azure Service Bus senders and receivers into your classes:
import { Injectable } from '@nestjs/common';
import { Sender, Receiver } from 'nestjs-azure-service-bus';
@Injectable()
export class MyService {
constructor(
@Sender('my-queue') private readonly sender: ServiceBusSender,
@Receiver('my-queue') private readonly receiver: ServiceBusReceiver,
) {}
// Use the sender and receiver in your methods
}
Replace 'my-queue'
with the name of your Azure Service Bus queue.
AzureServiceBusModule - Configuration Options
The forRoot
method of the AzureServiceBusModule
accepts a configuration object with two possible options:
connectionString
: The connection string for your Azure Service Bus namespace.fullyQualifiedNamespace
: The fully qualified namespace of your Azure Service Bus namespace.
You can provide either the connectionString
or the fullyQualifiedNamespace
, but not both.
AzureServiceBusModule - Dynamic Module Options
The forFeature
method of the AzureServiceBusModule
allows you to configure senders and receivers dynamically. It accepts an options object with two properties:
senders
: An array of sender names.receivers
: An array of receiver names.
import { Module } from '@nestjs/common';
import { AzureServiceBusModule } from 'nestjs-azure-service-bus';
@Module({
imports: [
AzureServiceBusModule.forFeature({
senders: ['queue-example'],
receivers: ['queue-example'],
}),
],
})
export class QueueModule {}
This will create senders and receivers for the specified queues.
import { ServiceBusSender } from '@azure/service-bus';
import { Injectable } from '@nestjs/common';
import { Sender } from 'nestjs-azure-service-bus';
@Injectable()
export class QueueSenderService {
constructor(
@Sender('test-queue') private readonly sender: ServiceBusSender,
) {}
async sendMessage(body: string) {
await this.sender.sendMessages({ body });
}
}
import { ServiceBusReceiver } from '@azure/service-bus';
import { Injectable, OnModuleInit } from '@nestjs/common';
import { Receiver } from 'nestjs-azure-service-bus';
@Injectable()
export class QueueReceiverService implements OnModuleInit {
constructor(
@Receiver('test-queue') private readonly receiver: ServiceBusReceiver,
) {}
onModuleInit() {
this.receiver.subscribe({
processMessage: async (message) => {
console.log(`message.body: ${message.body}`);
},
processError: async (args) => {
console.log(
`Error occurred with ${args.entityPath} within ${args.fullyQualifiedNamespace}: `,
args.error,
);
},
});
}
}
import { Module } from '@nestjs/common';
import { QueueSenderService } from './queue-sender.service';
import { AzureServiceBusModule } from 'nestjs-azure-service-bus';
import { QueueReceiverService } from './queue-receiver.service';
@Module({
imports: [
AzureServiceBusModule.forFeature({
receivers: ['test-queue'],
senders: ['test-queue'],
}),
],
providers: [QueueSenderService, QueueReceiverService],
exports: [QueueSenderService],
})
export class QueueModule {}
for another method the ServiceBusReceiver
and ServiceBusSender
see the azure sdk
AzureServiceBusAdminModule - Importing the module
To use the Azure Service Bus Admin module, import it into your NestJS application's root module:
import { Module } from '@nestjs/common';
import { AzureServiceBusAdminModule } from 'nestjs-azure-service-bus';
@Module({
imports: [
AzureServiceBusAdminModule.forRoot({
connectionString: '<your-connection-string>',
}),
],
})
export class AppModule {}
Replace <your-connection-string>
with your Azure Service Bus connection string.
AzureServiceBusAdminModule - Injecting Admin decorator
You can use the Admin
decorator provided by the module to inject Azure Service Bus admin client into your classes:
import { Injectable } from '@nestjs/common';
import { Admin } from 'nestjs-azure-service-bus';
@Injectable()
export class MyService {
constructor(
@Admin() private readonly admin: ServiceBusAdministrationClient,
) {}
async createQueue(queue: string){
return this.admin.createQueue(queue)
}
async createTopic(topic: string){
return this.admin.createTopic(topic)
}
async queueRuntimeProperties(queue: string){
return this.admin.getQueueRuntimeProperties(queue)
}
async deleteQueue(){
await this.admin.deleteQueue(queue)
}
//...
}
for another method the ServiceBusAdministrationClient
