【NestJs】日志模块重构

上一篇文章 我写了 【NestJs】日志收集，当然 那么些 在企业开发中会比较乱，也不是很符合开发规范，接下来的这一篇 调整一下文件结构。
借助cli功能开始重构：

日志模块

1. 创建文件

nest g mo logs 

logs.module.ts

import { Module } from '@nestjs/common';
import { utilities, WinstonModule, WinstonModuleOptions } from 'nest-winston';
import { ConfigService } from '@nestjs/config';
import * as winston from 'winston';
import { Console, DailyRotateFile } from 'winston/lib/winston/transports';
import 'winston-daily-rotate-file';
import { LogEnum } from '../enum/config.enum';

@Module({
  imports: [
    WinstonModule.forRootAsync({
      inject: [ConfigService],
      useFactory: (configService: ConfigService) => {
        const consoleTransPorts = new Console({
          level: 'info',
          format: winston.format.combine(
            winston.format.timestamp(),
            utilities.format.nestLike(),
          ),
        });
        const dailyRotateFile = new DailyRotateFile({
          level: 'warn',
          dirname: 'logs',
          filename: 'application-%DATE%.log',
          datePattern: 'YYYY-MM-DD-HH',
          zippedArchive: true,
          maxSize: '20m',
          maxFiles: '14d',
          format: winston.format.combine(
            winston.format.timestamp(),
            winston.format.simple(),
          ),
        });

        const dailyInfoRotateFile = new DailyRotateFile({
          level: configService.get(LogEnum.LOG_LEVEL),
          dirname: 'logs',
          filename: 'info-%DATE%.log',
          datePattern: 'YYYY-MM-DD-HH',
          zippedArchive: true,
          maxSize: '20m',
          maxFiles: '14d',
          format: winston.format.combine(
            winston.format.timestamp(),
            winston.format.simple(),
          ),
        });
        return {
          transports: [
            consoleTransPorts,
            ...(configService.get(LogEnum.LOG_ON)
              ? [dailyRotateFile, dailyInfoRotateFile]
              : []),
          ],
        };
      },
    }),
  ],
})
export class LogsModule {}

.ENV

DB_TYPE=mysql
DB_HOST=127.0.0.1
DB_PORT=3306

DB_SYNC=false

LOG_ON=true
LOG_LEVEL=info

main.ts

// import { Logger } from '@nestjs/common';
import { NestFactory } from '@nestjs/core';
import { WINSTON_MODULE_NEST_PROVIDER } from 'nest-winston';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule, {
  });
  app.useLogger(app.get(WINSTON_MODULE_NEST_PROVIDER));
  app.setGlobalPrefix('api/v1');
  const port = 3000;
  await app.listen(port);
}
bootstrap();

user.control.ts

import {
  Controller,
  Delete,
  Get,
  Patch,
  Post,
  Inject,
  LoggerService,
} from '@nestjs/common';
import { UserService } from './user.service';
import { ConfigService } from '@nestjs/config';
import { User } from './user.entity';
import { WINSTON_MODULE_NEST_PROVIDER } from 'nest-winston';

@Controller('user')
export class UserController {
  // private logger = new Logger(UserController.name);

  constructor(
    private userService: UserService,
    private configService: ConfigService,
    @Inject(WINSTON_MODULE_NEST_PROVIDER)
    private readonly logger: LoggerService,
  ) {
    this.logger.log('UserController init');
  }

  @Get()
  getUsers(): any {
    this.logger.log(`请求getUsers成功`);
    this.logger.warn(`请求getUsers成功`);
    this.logger.error(`请求getUsers成功`);
    return this.userService.findAll();
    // return this.userService.getUsers();
  }

}
