It is common in Owl components to have anonymous function as props. However, since each rendering create a different (but equivalent) closure, Owl will consider the props different, so will update the child component, but this is (often) not necessary. This commit will help reduce the problem by introducing a new `.alike` prop suffix, that will let Owl know that each version of that specific prop should be considered the same, so, will be ignored by the props comparison code. closes #1360
🦉 Owl overview 🦉
Here is a list of everything exported by the Owl library:
Main entities:
App: represent an Owl application (mainly a root component,a set of templates, and a config)Component: the main class to define a concrete Owl componentmount: main entry point for most application: mount a component to a targetxml: helper to define an inline template
Reactivity
useState: create a reactive object (hook, linked to a specific component)reactive: create a reactive object (not linked to any component)markRaw: mark an object or array so that it is ignored by the reactivity systemtoRaw: given a reactive objet, return the raw (non reactive) underlying object
Lifecycle hooks:
onWillStart: hook to define asynchronous code that should be executed before component is renderedonMounted: hook to define code that should be executed when component is mountedonWillPatch: hook to define code that should be executed before component is patchedonWillUpdateProps: hook to define code that should be executed before component is updatedonPatched: hook to define code that should be executed when component is patchedonWillRender: hook to define code that should be executed before component is renderedonRendered: hook to define code that should be executed after component is renderedonWillUnmount: hook to define code that should be executed before component is unmountedonWillDestroy: hook to define code that should be executed before component is destroyedonError: hook to define a Owl error handler
Other hooks:
useComponent: return a reference to the current component (useful to create derived hooks)useEffect: define an effect with its dependenciesuseEnv: return a reference to the current envuseExternalListener: add a listener outside of a component DOMuseRef: get an object representing a reference (t-ref)useChildSubEnv: extend the current env with additional information (for child components)useSubEnv: extend the current env with additional information (for current component and child components)
Utility/helpers:
EventBus: a simple event busloadFile: an helper to load a file from the servermarkup: utility function to define strings that represent html (should not be escaped)status: utility function to get the status of a component (new, mounted or destroyed)validate: validates if an object satisfies a specified schemawhenReady: utility function to execute code when DOM is ready
