SVG library for transitioning numbers with motion blur

JavaScript odometer or slot machine effect library for smoothly transitioning numbers with motion blur. Library uses functional approach and ES7 Function Bind Syntax. Internally based on SVG.

See the live version.

Installation

To install the stable version:

npm install --save bounty

Examples

The API is really simple and straigthforward:

importbountyfrom`bounty`;bounty({el: '.js-bounty',value: '£42,000,000'});

You can use it with other options:

importbountyfrom`bounty`;bounty({el: '.js-bounty',value: '£42,000,000',initialValue: '£900,000',lineHeight: 1.35,letterSpacing: 1,animationDelay: 100,letterAnimationDelay: 100,duration: 3000});

If you want to control ongoing animation just use methods from returned object:

importbountyfrom`bounty`;const{ cancel, pause, resume }=bounty({el: '.js-bounty',value: '£42,000,000'});constwait=(delay)=>newPromise((resolve)=>setTimeout(resolve,delay));constpasueAndRun=async()=>{awaitwait(1500);pause();awaitwait(2000);resume();awaitwait(2000);cancel();};pasueAndRun();

Library is built using UMD thus the following usage in HTML is possible.

<divclass="js-bounty"></div><scriptsrc="/bounty.js"></script><script>bounty.default({el: ".js-bounty",value: "£42,000,000"});</script>

The UMD build is also available on unpkg:

<scriptsrc="https://unpkg.com/bounty@1.1.6/lib/bounty.js"></script>

You can find the library on window.bounty.

That's it?

Yea! That's it. Other options like font-family and font-size are taken from computed styles so you can just style it like the other layers.

.js-bounty {
font-size:60px;
font-family: Roboto;
fill:#fff;
text-shadow:1px1px5pxrgba(0,0,0,0.5);
}

How?

If you're interested how it's made, see the presentation.

Roadmap

There is a work in progress to implement additional features:

• fromto API.
