nestjs-mongolog

Description

This package was created with the intention of facilitating and standardizing the writing of nestjs application logs in mongodb databases.

Instalation

npm i --save nestjs-mongolog

Quick Start

Import MongodbLogModule and use forRoot or forRootAsync static methods on your Module for initial configuration:

MongodbLogModule.forRootAsync({
  imports: [ConfigModule],

  useFactory: async (configService: ConfigService) => ({
    connectionString: configService.get<string>('DATABASE_URI'),
    databaseName: configService.get<string>('DATABASE_NAME'),
    collectionName: configService.get<string>('LOGS_COLLECTION_NAME'),
  }),

  inject: [ConfigService],
});

The fields to be passed in the configuration are as follows:

Import MongodbLogService on your service or controller and use the logging methods provided.

import { Controller, Get } from '@nestjs/common';

@Controller('cats')
export class CatsController {
  constructor(private readonly logger: MongodbLogService) {}

  @Get()
  findAll(): string {
    this.logger.info('listing all cats.', this.findAll.name);
    return 'This action returns all cats';
  }
}

Usage:

await this.logger.info('MESSAGE');
await this.logger.info({ fo: bar, ov: av });
await this.logger.info({ fo: bar, ov: av }, 'currentFunctionName ou any ContextData');
await this.logger.error('MESSAGE');
await this.logger.warn('MESSAGE');
await this.logger.debug('MESSAGE');
await this.logger.silly('MESSAGE');
await this.logger.fatal('MESSAGE');

You don't need to await writing logs if you don't want to.
