NestJS 8 Support

Version 3.x.x will support NestJS 8+. If you need support for NestJS 7 please continue to use Version 2.x.x. Thanks for you support!

About

@sunsave/nestjs-sentry implements a module, SentryModule, which when imported into your nestjs project provides a Sentry.io client to any class that injects it. This lets Sentry.io be worked into your dependency injection workflow without having to do any extra work outside of the initial setup.

Installation

npm install --save @sunsave/nestjs-sentry @sentry/node

Github Sample Project using @sunsave/nestjs-sentry

The following project was created as a sample starter project to get you going... (if needed...).

• @ntegral/nestjs-sentry sample

Getting Started

The simplest way to use @sunsave/nestjs-sentry is to use SentryModule.forRoot

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

@Module({
  imports: [
    SentryModule.forRoot({
      dsn: 'sentry_io_dsn',
      debug: true | false,
      environment: 'dev' | 'production' | 'some_environment',
      release: 'some_release', | null, // must create a release in sentry.io dashboard
      logLevels: ['debug'] //based on sentry.io loglevel //
    }),
  ],
})
export class AppModule {}

The async way @sunsave/nestjs-sentry is to use SentryModule.forRootAsync

import { Module } from '@nestjs-common';
import { SentryModule } from '@sunsave/nestjs-sentry';
import { ConfigModule } from '@sunsave/nestjs-config';
import { ConfigService } from '@sunsave/nestjs-config';

@Module({
  imports: [
    SentryModule.forRootAsync({
      imports: [ConfigModule],
      useFactory: async (cfg:ConfigService) => ({
        dsn: cfg.get('SENTRY_DSN'),
        debug: true | false,
        environment: 'dev' | 'production' | 'some_environment',
        release: 'some_release', | null, // must create a release in sentry.io dashboard
        logLevels: ['debug'] //based on sentry.io loglevel //
      }),
      inject: [ConfigService],
    })
  ]
})

export class AppModule {}

You can then inject the Sentry client into any of your injectables by using a custom decorator

import { Injectable } from '@nestjs/common';
import { InjectSentry, SentryService } from '@sunsave/nestjs-sentry';

@Injectable()
export class AppService {
  public constructor(@InjectSentry() private readonly client: SentryService) {
      client.instance().captureMessage(message, Sentry.Severity.Log);
      client.instance().captureException(exception);
      ... and more
  }
}

You can instruct Nest to use the SentryService as the default logger:

async function bootstrap() {
  const app = await NestFactory.create(AppModule, { logger: false });

  app.useLogger(SentryService.SentryServiceInstance());
  await app.listen(3000);
}
bootstrap();

You can instuct use the SentryService to log non-error messages as breadcrumbs or use the native Sentry.addBreadcrumb method.

import { Injectable } from '@nestjs/common';
import { InjectSentry, SentryService } from '@sunsave/nestjs-sentry';

@Injectable()
export class AppService {
  constructor(@InjectSentry() private readonly client: SentryService) {
    client.log('AppSevice Loaded', 'test', true); // creates log asBreadcrumb //
    client.instance().addBreadcrumb({
      level: 'debug',
      message: 'How to use native breadcrumb',
      data: { context: 'WhatEver' },
    });
    client.debug('AppService Debug', 'context');
  }
  getHello(): string {
    return 'Hello World!';
  }
}

Interceptors

BREAKING CHANGES: The SentryInterceptor can be used in projects that don't require GraphQL. If you will be needed GraphQL support, use the GraphqlInterceptor. Using the GraphqlInterceptor will create a dependancy for the @nestjs/graphql package.

npm install --save @nestjs/graphql

Using graphql interceptor globally

import { Module } from '@nestjs/common';
import { APP_INTERCEPTOR } from '@nestjs/core';
import { GraphqlInterceptor } from '@sunsave/nestjs-sentry';

@Module({
  ....
  providers: [
    {
      provide: APP_INTERCEPTOR,
      useFactory: () => new GraphqlInterceptor(),
    },
  ],
})
export class AppModule {}

Using the sentry interceptor globally

import { Module } from '@nestjs/common';
import { APP_INTERCEPTOR } from '@nestjs/core';
import { SentryInterceptor } from '@sunsave/nestjs-sentry';

@Module({
  ....
  providers: [
    {
      provide: APP_INTERCEPTOR,
      useFactory: () => new SentryInterceptor({
        filters: [{
          type: HttpException,
          filter: (exception: HttpException) => 500 > exception.getStatus() // Only report 500 errors
        }]
      }),
    }
  ],
})
export class AppModule {}

Flushing sentry

Sentry does not flush all the errors by itself, it does it in background so that it doesn't block the main thread. If you kill the nestjs app forcefully some exceptions have to be flushed and logged successfully.

If you want to force that behaviour use the close flag in your options. That is handy if using nestjs as a console runner. Keep in mind that you need to have app.enableShutdownHooks(); enabled in order for closing (flushing) to work.

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

@Module({
  imports: [
    SentryModule.forRoot({
      dsn: 'sentry_io_dsn',
      debug: true | false,
      environment: 'dev' | 'production' | 'some_environment',
      release: 'some_release', | null, // must create a release in sentry.io dashboard
      logLevels: ['debug'] //based on sentry.io loglevel //
      close: {
        enabled: true,
        // Time in milliseconds to forcefully quit the application
        timeout?: number,
      }
    }),
  ],
})
export class AppModule {}
