TmOdometer is inspired by and built on top of HubSpot's Odometer library. It enhances the original functionality by introducing modern TypeScript and ES Module support, along with precise decimal handling to ensure numbers with decimal places retain their accuracy during and after animations (e.g., 1200
with a precision of 2 will display as 1200.00
). Designed for seamless integration into any JavaScript or TypeScript project, it works effortlessly with modern module systems and bundlers.
While TmOdometer is a fully standalone library, it is also used as the foundation for the Angular version, TmNgOdometer, which provides seamless integration with Angular applications.
- Lightweight: Minimal dependencies and optimized for performance.
- TypeScript Support: Fully rewritten in TypeScript, the library provides type safety, an enhanced developer experience, and automatically generated type definitions.
- Flexible Integration: Works natively with ES Modules, CommonJS, AMD, and UMD bundles.
- Decimal Precision: Preserves decimal precision during animations.
- Customizable Themes: Supports various themes and animation styles.
- Dynamic Updates: Easily update values programmatically to trigger animations.

-
Install the library via npm:
npm install tm-odometer --save
-
Include one or more themes
<link rel="stylesheet" href="node_modules/tm-odometer/themes/odometer-theme-default.css" />
Tip: Replace
'default'
in the file path with any of the available themes:'car'
,'digital'
,'minimal'
,'plaza'
,'slot-machine'
,'train-station'
.
- Import the library using one of the following methods:
-
ES Modules:
import TmOdometer from 'tm-odometer';
Tip: If using TypeScript, types are directly provided with the library bundle.
-
CommonJS:
const TmOdometer = require('tm-odometer');
-
AMD:
require.config({ baseUrl: './src', paths: { 'tm-odometer': 'node_modules/tm-odometer/umd/tm-odometer', }, }); define(['tm-odometer'], function (TmOdometer) {});
-
Direct Inclusion
<script src="node_modules/tm-odometer/umd/tm-odometer.min.js"></script>
Once the library is imported, you can use it as follows:
const odometer = new TmOdometer({
el: document.getElementById('odometer-element'),
value: 1000,
animation: 'count',
duration: 2000,
format: '(,ddd).dd',
theme: 'default',
});
// Update the value programmatically
odometer.update(2000);
Tip: When included directly, the legacy
Odometer
constructor is also available for backward compatibility with older versions.
Another way to use the library is to add the odometer
class to any element in your HTML:
<div class="odometer">123</div>
Update the value programmatically:
document.querySelector('.odometer').innerHTML = 456;
// or
document.querySelector('.odometer').odometer.update(456);
The library supports the following configuration options:
Option | Type | Default | Description |
---|---|---|---|
el |
HTMLElement |
null |
The DOM element where the odometer will be rendered. |
value |
number |
0 |
The initial value of the odometer. |
animation |
string |
'slide' |
Animation effect type. Options: 'slide' , 'count' . |
duration |
number |
2000 (ms) |
Duration of the animation in milliseconds. |
format |
string |
'(,ddd).dd' |
Number format. Examples: '(,ddd)' → 12,345 , '(,ddd).dd' → 12,345.67 , (.ddd),dd → 12.345,67 . |
theme |
string |
'default' |
Theme for the odometer. Options: 'default' , 'car' , 'digital' , 'minimal' , 'plaza' , 'slot-machine' , 'train-station' . |
You can configure all odometer instances globally by defining the window.odometerOptions
object before including or importing the tm-odometer
library:
<script>
window.odometerOptions = {
animation: 'count', // Animation type ('slide' or 'count')
duration: 3000, // Animation duration in milliseconds
format: '(,ddd).dd', // Number format
theme: 'car', // Theme for all instances
};
</script>
<script src="tm-odometer/umd/tm-odometer.min.js"></script>
If you need to configure a single odometer instance differently from the global configuration, you can initialize it programmatically using the TmOdometer
constructor:
<div id="custom-odometer"></div>
<script>
const customOdometer = new TmOdometer({
el: document.getElementById('custom-odometer'),
value: 123,
animation: 'count', // Animation type ('slide' or 'count')
duration: 3000, // Animation duration in milliseconds
format: '(,ddd).dd', // Number format
theme: 'minimal', // Theme for this instance
});
// Update the value programmatically
setTimeout(() => {
customOdometer.update(4567.89);
}, 1000);
</script>
To help you get started, TmOdometer includes a comprehensive set of demos showcasing its usage with different module formats (CJS, ESM, UMD, AMD, and legacy). Each demo is a self-contained project that you can run locally.
Demo | Description |
---|---|
ESM | Demonstrates usage with native ES Modules in modern browsers. |
CJS | Demonstrates usage with CommonJS in bundlers such as Webpack or ESBuild. |
UMD Browser | Demonstrates usage with UMD bundles directly in the browser via <script> . |
UMD AMD | Demonstrates usage with AMD Modules in environments like RequireJS. |
Legacy | Demonstrates usage with the legacy version for older browsers. |
