Log4js

Log4js - The Logging Framework for JavaScript with no runtime dependencies | Since 2005

Usage

  • Download the most current release and unzip the archive.
  • Copy the file js/log4js.min.js to your project.
  • Add the JavaScript file to head of HTML page: 
    <head>
  <script src="log4js.min.js" type="text/javascript"></script>
</head>
  • Add script for instantiation of Logger: 
    let consoleLog = new Log4js.Logger("consoleTest");
consoleLog.setLevel(Log4js.Level.ALL);
let consoleAppender = new Log4js.ConsoleAppender(true);
consoleLog.addAppender(consoleAppender);
  • Then you are able to add logging event: 
    consoleLog.trace('I was traced!')

Within sources there is a more detailed example.
