Package Exports

better-loger
better-loger/console_appender

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 (better-loger) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

node logger

import Logger from 'better-loger';
import FileAppender from 'better-loger/file_appender';
import ConsoleAppender from 'better-loger/console_appender';

// 日志输出到文件,配置logrotate:
const fileAppender = new FileAppender({
  // 标准输出目标
  locate: 'access.log',
  // 错误输出目标
  errorLocate: 'error.log',
  // rotate保留最多3个文件
  keepLogNum: 3,
  // 每天做一次rotate
  rotateInterval: 24 * 60 * 60 * 1000,
  // 当使用级别>=info时候,才输出到文件
  threshold: 'info',
  // 做rotate的最小大小:200Mb
  thresholdSize: 200 * 1024 * 1024,
});

// 输出到console
const consoleAppender = new ConsoleAppender({
  threshold: 'debug'
});

// 获取logger对象,唯一key,默认集成了consoleAppender
const logger = Logger.get('uniqId');
// 设置日志等级,当方法等级超过设置的等级且超过了appender等级,才会输出
logger.setLevel('debug')
// 设置appender为console
logger.setAppender(consoleAppender);
// 添加文件appender
logger.addAppender(fileAppender);

// 使用默认模板
logger.debug('这是一条debug消息');
// 自定义模板,用来记录访问日志
// %e表示logger实例化时候时间,%i表示实例化时候生成的6位随机id,n表示从实例化到当前过了多少毫秒
// 全部定义见formatter.help(方法)
logger.info(`%e|%i|%4m|%60m|%7m|%5n`, [
  'GET',
  'http://www.yourdomain.com/path',
  'success',
]);
