**Try it online!** you can experiment with the Owl framework in an online [playground](https://odoo.github.io/owl/playground).
## Project Overview
The Odoo Web Library (Owl) is a smallish (~<20kb gzipped) UI framework built by
[Odoo](https://www.odoo.com/) for its products. Owl is a modern
framework, written in Typescript, taking the best ideas from React and Vue in a
simple and consistent way. Owl's main features are:- a declarative component system,
- a fine grained reactivity system similar to Vue,
- hooks
- fragments
- asynchronous renderingOwl components are defined with ES6 classes and xml templates, uses an
underlying virtual DOM, integrates beautifully with hooks, and the rendering is
asynchronous.Quick links:
- [documentation](#documentation),
- [changelog](CHANGELOG.md) (from Owl 1.x to 2.x),
- [playground](https://odoo.github.io/owl/playground)## Example
Here is a short example to illustrate interactive components:
```javascript
const { Component, useState, mount, xml } = owl;class Counter extends Component {
static template = xml`
Click Me! []
`;state = useState({ value: 0 });
}class Root extends Component {
static template = xml`
Hello Owl
`;static components = { Counter };
}mount(Root, document.body);
```Note that the counter component is made reactive with the [`useState` hook](doc/reference/hooks.md#usestate).
Also, all examples here uses the [`xml` helper](doc/reference/templates.md#inline-templates) to define inline templates.
But this is not mandatory, many applications will load templates separately.More interesting examples can be found on the
[playground](https://odoo.github.io/owl/playground) application.## Documentation
