core/snapshot

Utilities to facilitate integration with v8 snapshot builds

Import Usage

import snapshot from '@enact/core/snapshot';

Members

isWindowReady   Function

isWindowReady(  ) → Boolean

Determines if the window is available

0 Params

Returns

 Boolean

true when window is ready

onWindowReady   Function

onWindowReady( callback ) → undefined

Executes a callback, such as registering event handlers, when a valid window is available.

During normal operation, the callback will be executed immediately. During a pre-rendering pass, the callback is not be executed at all. When using snapshot, the callback is added to a queue and is executed in order once the window is available.

Important Notes

• The callback should not alter the initial HTML state. If it does, it will invalidate the pre-render state and interfere with React rehydration.

• The callback should be limited to module-scoped actions and not component instance actions. If the action is tied to a component, it should be invoked from within the component's lifecycle methods.
