  fileLogger: {
    // ...

日志打印

使用 Logger 类，不推荐

import { Logger } from '@nestjs/common'

export class MyService {
  private readonly logger = new Logger(MyService.name)
  foo() {
    this.logger.verbose({ foo: 'bar' }, 'baz %s', 'qux')
    this.logger.debug('foo %s %o', 'bar', { baz: 'qux' })
    this.logger.log('foo')
  }
}

使用 InjectLogger 装饰器，推荐

import { InjectLogger, NestLogger } from '@142vip/nest-logger'

export class MyService {
  constructor(
    private readonly logger: PinoLogger
  ) {
    this.logger.setContext(MyService.name)
  }

  constructor(
    @InjectLogger(MyService.name)
    private readonly logger: NestLogger
  ) {}

  foo() {
    // PinoLogger has same methods as pino instance
    this.logger.trace({ foo: 'bar' }, 'baz %s', 'qux')
    this.logger.debug('foo %s %o', 'bar', { baz: 'qux' })
    this.logger.info('foo')
  }
}

构造函数初始化

import { InjectLogger, NestLogger } from '@142vip/nest-logger'

export class MyService {
  constructor(
    private readonly logger: NestLogger
  ) {
    this.logger.setContext(MyService.name)
  }

  foo() {
    this.logger.trace({ foo: 'bar' }, 'baz %s', 'qux')
    this.logger.debug('foo %s %o', 'bar', { baz: 'qux' })
    this.logger.info('foo')
  }
}
