Description
I'm new to nest.js. I don't know why Nest cant resolve dependencies. And there is nothing in README. I had found something similar in closed issues but it didn't help. Here is an error
Error: Nest can't resolve dependencies of the AlertProvider (?). Please make sure that the argument at index [0] is available in the AlertModule context.
Here is my files (cleaned up a little bit):
// app/app.module.ts
import { Module } from '@nestjs/common';
@Module({
imports: [
ConfigModule.load(
path.resolve(process.cwd(), 'config', '**/!(*.d).{ts,js}'),
),
AmqpModule.forRootAsync({
inject: [ConfigService],
useFactory: (config: ConfigService) => config.get('amqp'),
}),
//...
})
export class AppModule implements NestModule// config/amqp.ts
export default {
name: 'default',
hostname: process.env.AMQP_HOST || 'mq-service',
port: process.env.AMQP_PORT || 5672,
username: process.env.USERNAME || 'guest',
password: process.env.PASSWORD || 'guest',
};// alert/alert.module.ts
import { Module } from '@nestjs/common';
import { AmqpModule } from 'nestjs-amqp';
import { AlertService } from './alert.service';
import { AlertProvider } from './alert.provider';
@Module({
imports: [
AmqpModule.forFeature(), // The error also occurs without this line
],
providers: [
AlertService,
AlertProvider,
],
})
export class AlertModule {}// alert/alert.provider.ts
import { InjectAmqpConnection } from 'nestjs-amqp';
const QUEUE = 'alerts';
export class AlertProvider {
constructor(
@InjectAmqpConnection('default') private readonly amqp,
) {
this.setupListeners();
}
async setupListeners() {
const channel = await this.amqp.createChannel();
await channel.assertQueue(QUEUE);
channel.consume(QUEUE, (msg) => {
if (msg === null) {
return;
}
console.log(msg.content.toString());
});
}
}Maybe you can suggest me something.
I use nest@v6 and latest version of nestjs-amqp
