TouchPoint.js

A tiny (3.86 kb minified) vanilla JavaScript library made for in-browser HTML prototyping (as part of the UX process) that visually shows where the user clicks/taps on-screen using CSS3 transforms and transitions. TouchPoint is highly customizable, mobile ready and great for screencasting, screen recording, user testing and presentations. Library now built for ES6 and ES5.

Installation

ES5

Download and include touchpoint.js or touchpoint.min.js in the <head> or at the end of the <body> (recommended) in your HTML document. There are no dependencies:

<script src="touchpoint-es5.min.js"></script>

ES6

Same instructions as above, but you will need a polyfill to run in-browser. I use babel-polyfill which can be installed on your machine by using NPM from your command line.

<script src="node_modules/babel-polyfill/dist/polyfill.min.js"></script>
<script src="touchpoint.min.js"></script>

Quick Start/How to Use

After you load the script you simply initialize TouchPoint and add an event listener to whichever DOM element you want TouchPoint to show over:

<script>
	TouchPoint.init();
</script>

That's it!

Start clicking away on the page to see it in action.

Options

TouchPoint is customizable. There are a number of options that you have access to to customize the look for your needs. It's important that these options be defined before you initialize TouchPoint with TouchPoint.init(). Otherwise, your updates won't show.

Color

Change the default color of TouchPoint. Any valid CSS color can be used.

Default value: '#FFF'

TouchPoint.color = 'red';

DOM

Change the default DOM element that TouchPoint will be active over. Any valid selector can be used: element name, CSS class or ID. If you want TouchPoint to only show on a specific element, make sure that that element is set to overflow: visible, otherwise TouchPoint will get clipped.

Default value: window

TouchPoint.dom = elementVarId;

or (recommended)

TouchPoint.init(elementVarId);

Opacity

Change the opacity of the TouchPoint. You can use any value between 0 and 1.

Default value: 0.8

TouchPoint.opacity = 0.5;

Scale

Change the final scale of the TouchPoint. This value can range from 0 and beyond.

Default value: 8

TouchPoint.scale = 14;

Size

Change the initial size of the TouchPoint. This value is px.

Default value: 20

TouchPoint.size = 5;

Performance

Performance should not be an issue because each individual TouchPoint element is dynamically created and then automatically removed from the DOM after being used.

The animation is handled via the requestAnimationFrame function that is available in all current browsers. This has better overall performance than using setTimeout, which doesn't redraw consistently.
