Description

This module contains integrated healthchecks for Nest.

Installation

@nestjs/terminus integrates with a lot of cool technologies, such as typeorm, grpc, mongodb, and many more! In case you have missed a dependency, @nestjs/terminus will throw an error and prompt you to install the required dependency. So you will only install what is actually required!

npm install --save @nestjs/terminus

Usage

  1. Import the Terminus module
  2. Make sure the additionally needed modules are available to (e.g. TypeOrmModule), in case you want to do Database Health Checks.
// app.module.ts

@Module({
  controllers: [HealthController],
  imports:[
    // Make sure TypeOrmModule is available in the module context
    TypeOrmModule.forRoot({ ... }),
    TerminusModule
  ],
})
export class HealthModule { }
  1. Setup your HealthController which executes your Health Check.
// health.controller.ts

@Controller('health')
export class HealthController {
  constructor(
    private health: HealthCheckService,
    private db: TypeOrmHealthIndicator,
  ) {}

  @Get()
  @HealthCheck()
  readiness() {
    return this.health.check([
      async () => this.db.pingCheck('database', { timeout: 300 }),
    ]);
  }
}

If everything is set up correctly, you can access the healthcheck on http://localhost:3000/health.

{
  "status": "ok",
  "info": {
    "database": {
      "status": "up"
    }
  },
  "details": {
    "database": {
      "status": "up"
    }
  }
}
