JSPM – @djeka07/nestjs-loki-logger@1.2.0

Package Exports

@djeka07/nestjs-loki-logger
@djeka07/nestjs-loki-logger/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@djeka07/nestjs-loki-logger) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

NestJS Loki Logger

Introduction

A logger that logs to Grafana Loki.

Installation

yarn add @djeka07/nestjs-loki-logger

Usage

Importing module

import { LokiLoggerModule } from '@djeka07/nestjs-loki-logger';
@Module({
  imports: [
    LokiLoggerModule.forRoot({
      app: 'app-name',
      host: 'host',
      userId: 'user id',
      password: 'password',
      environment: 'development' | 'production', // Optional, defaults to production
      logDev: false, // Optional, default to false
      minLogLevel: LogLevel.verbose, // Optional, defaults to LogLevel.verbose
    }),
  ],
  providers: [],
  exports: [],
})
export class AModule {}

Importing module Async

import { LokiLoggerModule } from '@djeka07/nestjs-loki-logger';
@Module({
  imports: [
    LokiLoggerModule.forRootAsync({
      useFactory: async () => {
        return {
          app: 'app-name',
          host: 'host',
          userId: 'user id',
          password: 'password',
          environment: 'development' | 'production', // Optional, defaults to production
          logDev: false, // Optional, default to false
          minLogLevel: LogLevel.verbose, // Optional, defaults to LogLevel.verbose
        };
      },
    }),
  ],
  providers: [],
  exports: [],
})
export class AModule {}

Use logger for nest logging

import { NestFactory } from '@nestjs/core';
import { MainModule } from './main.module';
import { LokiLoggerService } from '@djeka07/nestjs-loki-logger';


async function bootstrap() {
  const app = await NestFactory.create(MainModule, {
    bufferLogs: true,
  });
  app.useLogger(app.get(LokiLoggerService));
  await app.listen(3000, '0.0.0.0');
}
bootstrap();

Use request logging interceptor

import { LokiLoggerModule, LokiRequestLoggingInterceptor } from '@djeka07/nestjs-loki-logger';
@Module({
  imports: [
    LokiLoggerModule.forRootAsync({
      useFactory: async () => {
        return {
          app: 'app-name',
          host: 'host',
          userId: 'user id',
          password: 'password',
          environment: 'development' | 'production', // Optional, defaults to production
          logDev: false, // Optional, default to false
          minLogLevel: LogLevel.verbose, // Optional, defaults to LogLevel.verbose
        };
      },
    }),
  ],
  providers: [LokiRequestLoggerInterceptorProvider],
  exports: [],
})
export class AModule {}

Use the log service

import { LokiLoggerService } from '@djeka07/nestjs-loki-logger';

@Injectable()
export class AService {
  constructor(private readonly loggerService: LokiLoggerService) {
    this.loggerService.verbose('message', [{ optionalProps: 'optionalProps' }])
  }
}
