@sentry/nestjs

Official Sentry SDK for NestJS

Installation

npm install @sentry/nestjs

# Or yarn
yarn add @sentry/nestjs

Usage

Add an instrument.ts file:

import * as Sentry from '@sentry/nestjs';

Sentry.init({
  dsn: '__DSN__',
  // ...
});

You need to require or import the instrument.ts file before requiring any other modules in your application. This is necessary to ensure that Sentry can automatically instrument all modules in your application:

// Import this first!
import './instrument';

// Now import other modules
import * as Sentry from '@sentry/nestjs';
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(3000);
}

bootstrap();

Afterwards, add the SentryModule as a root module to your main module:

import { Module } from '@nestjs/common';
import { SentryModule } from '@sentry/nestjs/setup';

@Module({
  imports: [
    SentryModule.forRoot(),
    // ...other modules
  ],
})
export class AppModule {}

In case you are using a global catch-all exception filter (which is either a filter registered with app.useGlobalFilters() or a filter registered in your app module providers annotated with an empty @Catch() decorator), add a @SentryExceptionCaptured() decorator to the catch() method of this global error filter. This decorator will report all unexpected errors that are received by your global error filter to Sentry:

import { Catch, ExceptionFilter } from '@nestjs/common';
import { SentryExceptionCaptured } from '@sentry/nestjs';

@Catch()
export class YourCatchAllExceptionFilter implements ExceptionFilter {
  @SentryExceptionCaptured()
  catch(exception, host): void {
    // your implementation here
  }
}

In case you do not have a global catch-all exception filter, add the SentryGlobalFilter to the providers of your main module. This filter will report all unhandled errors that are not caught by any other error filter to Sentry. Important: The SentryGlobalFilter needs to be registered before any other exception filters.

import { Module } from '@nestjs/common';
import { APP_FILTER } from '@nestjs/core';
import { SentryGlobalFilter } from '@sentry/nestjs/setup';

@Module({
  providers: [
    {
      provide: APP_FILTER,
      useClass: SentryGlobalFilter,
    },
    // ..other providers
  ],
})
export class AppModule {}

Note: In NestJS + GraphQL applications replace the SentryGlobalFilter with the SentryGlobalGraphQLFilter.

SentryTraced

Use the @SentryTraced() decorator to gain additional performance insights for any function within your NestJS applications.

import { Injectable } from '@nestjs/common';
import { SentryTraced } from '@sentry/nestjs';

@Injectable()
export class ExampleService {
  @SentryTraced('example function')
  async performTask() {
    // Your business logic here
  }
}

SentryCron

Use the @SentryCron() decorator to augment the native NestJS @Cron decorator to send check-ins to Sentry before and after each cron job run.

import { Cron } from '@nestjs/schedule';
import { SentryCron, MonitorConfig } from '@sentry/nestjs';
import type { MonitorConfig } from '@sentry/core';

const monitorConfig: MonitorConfig = {
  schedule: {
    type: 'crontab',
    value: '* * * * *',
  },
  checkinMargin: 2, // In minutes. Optional.
  maxRuntime: 10, // In minutes. Optional.
  timezone: 'America/Los_Angeles', // Optional.
};

export class MyCronService {
  @Cron('* * * * *')
  @SentryCron('my-monitor-slug', monitorConfig)
  handleCron() {
    // Your cron job logic here
  }
}
