<h1 align="center">🦉 <a href="https://odoo.github.io/owl/">Odoo Web Library</a> 🦉</h1>
|
|
|
|
_A web framework for structured, dynamic and maintainable applications_
|
|
|
|
## Project Overview
|
|
|
|
The Odoo Web Library (OWL) is a small
|
|
UI framework intended to be the basis for the [Odoo](https://www.odoo.com/) Web Client, and hopefully many
|
|
other Odoo related projects. OWL's main feature is a _declarative component system_, with QWeb as a template engine, asynchronous rendering, and an underlying virtual dom.
|
|
|
|
**Try it online!** An online playground is available at [https://odoo.github.io/owl/playground](https://odoo.github.io/owl/playground) to let you experiment with the OWL framework.
|
|
|
|
## OWL's Design Principles
|
|
|
|
OWL is designed to be used in highly dynamic applications where changing
|
|
requirements are common, code needs to be maintained by large teams.
|
|
|
|
- **XML based**: templates are based on the XML format, which allows interesting
|
|
applications. For example, they could be stored in a database and modified
|
|
dynamically with `xpaths`.
|
|
- **templates compilation in the browser**: this may not be a good fit for all
|
|
applications, but if you need to generate dynamically user interfaces in the
|
|
browser, this is very powerful. For example, a generic form view component
|
|
could generate a specific form user interface for each various models, from a XML view.
|
|
- **no toolchain required**: this is extremely useful for some applications, if,
|
|
for various reasons (security/deployment/dynamic modules/specific assets tools),
|
|
it is not ok to use standard web tools based on `npm`.
|
|
|
|
Owl is not designed to be fast or small (even though it is quite good on those
|
|
two topics). If you are interested in a comparison with React or Vue, you will
|
|
find some more information [here](doc/comparison.md).
|
|
|
|
## Example
|
|
|
|
Here is a short example to illustrate interactive components:
|
|
|
|
```xml
|
|
<templates>
|
|
<button t-name="Counter" t-on-click="increment">
|
|
Click Me! [<t t-esc="state.value"/>]
|
|
</button>
|
|
</templates>
|
|
```
|
|
|
|
```javascript
|
|
class Counter extends owl.Component {
|
|
state = { value: 0 };
|
|
|
|
increment() {
|
|
this.state.value++;
|
|
}
|
|
}
|
|
|
|
const qweb = new owl.QWeb(TEMPLATES);
|
|
const counter = new Counter({ qweb });
|
|
counter.mount(document.body);
|
|
```
|
|
|
|
Note that we assume here that the xml templates are available in the `TEMPLATES`
|
|
string. More interesting examples can be found on the
|
|
[playground](https://odoo.github.io/owl/playground) application.
|
|
|
|
## Installing/Building
|
|
|
|
If you want to use a simple `<script>` tag, the last release can be downloaded here:
|
|
|
|
- [owl-0.16.0.js](https://github.com/odoo/owl/releases/download/v0.16.0/owl.js)
|
|
- [owl-0.16.0.min.js](https://github.com/odoo/owl/releases/download/v0.16.0/owl.min.js)
|
|
|
|
Some npm scripts are available:
|
|
|
|
| Command | Description |
|
|
| --------------------- | ---------------------------------------------------------------------------- |
|
|
| `npm install` | install every dependency required for this project |
|
|
| `npm run build` | build a bundle of _owl_ in the _/dist/_ folder |
|
|
| `npm run minify` | minify the prebuilt owl.js file |
|
|
| `npm run test` | run all tests |
|
|
| `npm run test:watch` | run all tests, and keep a watcher |
|
|
| `npm run tools` | build tools applications, start a static server (see [here](doc/tooling.md)) |
|
|
| `npm run tools:watch` | same as `tools`, but with a watcher to rebuild owl |
|
