使用

######1.默认使用

var logger = require("snx-logger").logger;
var log  = logger.createLogger();
log.debug("test");
// [2014-11-27T08:36:36.886Z][default][debug][test]

默认设定

"default": {
  CustomConsole: {
    level: "debug",
    output: "string",
    layout: "timestamp:category:level:message"
  }
}

######2.指定category

var logger = require("snx-logger").logger;
var log  = logger.createLogger(“sample”);
log.debug("test");
// [2014-11-27T08:36:36.886Z][sample][debug][test]

默认设定

"default": {
  CustomConsole: {
    level: "debug",
    output: "string",
    layout: "timestamp:category:level:message"
  }
}

######3.自定义布局

var config = {
 "application": {
    "CustomConsole": {
      "level": "debug"
    , "output": "string"
    , "layout": "category:level:time:hostname:file:function:line:message"
    },
    "CustomFile": {
      "level": "debug"
    , "output": "json"
    , "filename": "logs/application.log"
    , "layout": "category:level:time:hostname:file:function:line:message"
    , "maxsize": 20480
    }
  }
};
var logger = require("snx-logger").logger;
var log  = logger.createLogger("application", config);
log.debug("test");
// [application][debug][time][xxx][xxxx][xxx][xx][test]

######4.使用配置文件，定义全局布局

var logger = require("snx-logger").logger;
logger.configure("/path/../configLog.js");
var log  = logger.createLogger("application");
log.debug("test");
//

######5.使用express的场合

var logger = require("snx-logger").logger;
var express = require('express')
var app = express()

var configSample = {
  "accessSample": {
    "CustomConsole": {
      "level": "debug"
      , "output": "string"
      , "layout": "category:level:timestamp:requestURL:requestIP:responseCode:responseTime"
    },
    "CustomFile": {
      "level": "debug"
      , "output": "json"
      , "filename": "logs/accessSample.log"
      , "layout": "category:level:timestamp:requestURL:requestIP:responseCode:responseTime"
      , "maxsize": 20480
    }
  }
};
app.use(logger.use("accessSample", configSample));
// [accessSample][info][2014-11-27T08:25:04.760Z][GET /][127.0.0.1][200][0.464ms]
