v0.22.0

0.22.0

The hooks release.

This release contains a few breaking changes necessary to improve the API. It is
actually very nice to work with hooks in Owl.

The main breaking change is that now components do not have a special state
key, which is observed. If a component needs reactive state, it has to explicitely
import the useState hook:

class C extends Component {
    state = useState({some: 'value'});
    ...
}

Changes

• component: reorganize the rendering system with the notion of fiber
• component: support fully dynamic t-component directives
• component tags: allow injecting values in xml tag string
• qweb fix: properly support svg
• components: add hooks mechanism (breaking change)
• hooks: implement useRef hook (breaking change)

v0.21.0

v0.21.0

Not many changes, but they will significantly improve the developer experience. The main idea is that we are getting closer to having nice single file components.

Changes

• fix: qweb crash in some cases involving t-call, multiple sub nodes and one text node
• component: the components key is now static (breaking change)
• component: support dynamic root nodes (either subcomponent or dom nodes) and switching between them
• component: add support for dynamic props with t-props
• router: replace the t-routecomponent directive with RouterComponent (breaking change)
• component: make the template key static (breaking change)
• qweb: add QWeb.registerTemplate method
• qweb: rename register method to registerComponent (breaking change)
• tags: introduce the xml tag
