Info Monitor

JavaScript Performance Monitor

A typescript implementation similar to a awesome tool from mrdoob/stats.js.

This class provides a simple info box that will help you monitor your code performance.

• FPS Frames rendered in the last second. The higher the number the better.
• MS Milliseconds needed to render a frame. The lower the number the better.
• MB MBytes of allocated memory. (Run Chrome with --enable-precise-memory-info)
• User-defined panel support too.

Get Started

via <script> Tag

1. Get the info.min.js

You can find it in git repo release/info.min.js

git clone https://github.com/kiochan/info-monitor

2. Move info.min.js into your project, then link script into your html files before </body> tag:

<!-- ... some code -->

    <script src="<path-to-js>/info.min.js" charset="utf-8"></script>
    <script type="text/javascript">
      !function() {
        var monitor = new Info()
        document.body.appendChild(monitor.getElement())
        monitor.displayPanel(0)

        function animate() {

          monitor.begin();

          // monitored code goes here

          monitor.end();

          requestAnimationFrame(animate)
        }
        requestAnimationFrame(animate)
      }()
    </script>

  </body>
</html>

via npm

1. Install

npm install --save info-monitor

2. Just import (javascript and typescript both are fine)

import Info from 'info'

!function() {
  let monitor = new Info()
  document.body.appendChild(monitor.getElement())
  monitor.displayPanel(0)

  function animate() {

    monitor.begin();

    // monitored code goes here

    monitor.end();

    requestAnimationFrame(animate)
  }
  requestAnimationFrame(animate)
}()

Bookmarklet You can add this code to any page using the following bookmarklet:

javascript:(function(){var script=document.createElement('script');script.onload=function(){var m=new Info();document.body.appendChild(m.getElement());requestAnimationFrame(function loop(){m.update();requestAnimationFrame(loop)});};script.src='//rawgit.com/kiochan/info-monitor/master/release/info.min.js';document.head.appendChild(script);})()

User-Defined Panel

Create your own classes and extend it with my Info or InfoProto class

InfoProto dosen't contain any panel.

import {Info, Panel} from 'info'

class MyInfo extends Info {
  constructor() {
    super()
    this.addPanel(new Panel({
      name: 'MauseMove',
      fgColor: '#f00',
      bgColor: '#200'
    }
    this.on('begin', (event) => {
      // some code here
    })
    this.on('end', (event) => {
      // some code here
    })
  }
}
