NestJS Rollbar package allows you to extend standard Logger to send errors directly to Rollbar. Usage if quite simple. Get Rollbar Token from your project page and install nestjs-rollbar package:
npm i nestjs-rollbar
Then register module in your root app.module
import { LoggerModule } from 'nestjs-rollbar';
@Module({
imports: [
// ...
LoggerModule.forRoot({
accessToken: configService.get('ROLLBAR_TOKEN'),
environment: configService.get('ENVIRONMENT'),
}),
],
})
export class AppModule {}
forRoot
method uses RollBar NodeJS configuration interface
Or, using forRootAsync
:
import { ConfigModule, ConfigService } from '@nestjs/config';
import { LoggerModule } from 'nestjs-rollbar';
@Module({
imports: [
// ...
LoggerModule.forRootAsync({
imports: [ConfigModule],
inject: [ConfigService],
useFactory: (configService: ConfigService) => ({
accessToken: configService.get('ROLLBAR_TOKEN'),
environment: configService.get('ENVIRONMENT'),
}),
}),
],
})
export class AppModule {}

To use RollbarLogger in any service or controller just inject it in constructor:
import { RollbarLogger } from 'nestjs-rollbar';
constructor(
private readonly rollbarLogger: RollbarLogger
) {}
To log an error to Rollbar just call error()
method:
try {
throw new Error('Test error');
} catch (error) {
this.rollbarLogger.error(error, 'myMethod');
}
First parameter is an error object and the second - name of your method to show in logs.
If you want to automatically log error in controller or services method you can use RollbarHandler decorator.
@Injectable()
export class AppService {
@RollbarHandler()
getHello() {
throw new Error('asda');
}
}
It will catch all errors in method and send them directly to Rollbar and print them in console. If you want to customize error name, pass it to decorator:
@RollbarHandler({
errorName: 'My error name',
})
To rethrow error to another decorator:
@RollbarHandler({
rethrow: true,
})
