Simple Example 一个简单的示例

//a simple example for AvenirLog 
//本程序提供一个简单的示例
const AvenirLog = require('avenir-log');
async function main() {
    let log = new AvenirLog('test','./log');   //logFileName,logOutPath,1-日志文件名，2-日志文件的存放目录
    log.noDebug()
    log.noConsoleLog();
    global.log = log;       //For direct use 这样之后可以在其他文件直接使用

    //5 log types 五种日志记录类型
    log.debug('write log');
    log.error('write error');
    log.warn("write warn");
    log.log('write object',{code:200,data:'error'}); 
    log.info('write info');       
}

main();

Results

in ./log/test_20201127.log

[debug] 2020-11-27 11:58:43 : write log
[error] 2020-11-27 11:58:43 : write error
[warn] 2020-11-27 11:58:43 : write warn
[log] 2020-11-27 11:58:43 : write object {"code":200,"data":"error"}

APIS

• 1.debug(...args) usage same as console.log() 和console.log()一样，逗号分隔参数
• 2.error(...args) omited
• 3.info(...args) omited
• 4.log(...args) omited
• 5.warn(...args) omited
• 6.init(fileName,filePath) same as constructor let log = new Logger('test','./log'); 和构造函数的用法一样
• 7.noDebug() use this function once to avoid log debugs to file，Just like a switch调用一次这个函数，就不会写入debug到日志里面了，和开关一样。
• 8.noConsoleLog use this function once to avoid console.log("your logs")，Just like a switch调用一次这个函数，就不会把日志同时输出一遍了，和开关一样。
