super-log

Node.js程序的简单日志记录器

使用方法

var SuperLog = require('super-log');
 
// 初始化
var mylogger = SuperLog.create({
  interval: 2000, // 自动保存时间间隔，ms，默认2000
  path: '/tmp/logs', // 文件存储根目录
  formatInput: function (data) {
    // 格式化输入的数据，并返回新的数据，默认直接返回
    return data;
  },
  formatOutput: function (data) {
    // 格式化输出的数据，并返回新的数据，默认直接返回
    return data;
  },
  dataStringify: function (data) {
    // 将数据转换成字符串，默认如下：
    return JSON.stringify(data);
  },
  dataParse: function (data) {
    // 将字符串还原回原始数据，默认如下：
    return JSON.parse(data);
  },
  getFileName: function () {
    // 返回当前文件名，比如：：
    return date('Ymd/Ymd-H') + '.log';
  },
  sort: function (a, b) {
    // 对两条记录进行排序，默认如下：
    return a.timestamp - b.timestamp;
  },
  query: {
    // 使用时执行 mylogger.queryByDay()
    day: function (day, callback) {
      // 调用 queryPath() 来查询某个目录下的所以文件
      this.queryPath(day, callback);
    }
  }
});
 
// 记录日志
mylogger.log('这里是logs');
 
// 马上把当前日志写到文件
mylogger.flush();
 
// 退出
mylogger.destroy();
