React wake-lock component
Introduction
This is an invisible React component that tries to keep the browser/client awake - especially for mobile devices.
Installation
npm i --save react-wakelock-react16
How to use (READ THIS! IMPORTANT!)
import WakeLock from 'react-wakelock-react16';
render() {
return (
<div>
...
<WakeLock />
...
</div>
);
}
Just add the component to your application. By default it is immediately "enabled".
WARNING: Due to browser limitations the wake-lock is not effective until the user first clicks/touches somewhere in the document. So, after adding/enabling the component, it will not prevent sleep until the user interacts with the page in some way (scrolling not being an interaction).
This limitation does not apply to iOS devices.
How this works
The component uses two methods, depending on the operating system.
On Android, a invisible dummy-video is played in the background.
On iOS, an (hopefully unnoticeable) dummy navigation is performed every 15 seconds.
Props
-
preventSleep
- (true
by default). You can use this property to control the component behavior. Sleep is prevented only inpreventSleep===true
state.
Credits
The component is based on NoSleep.js by Rich Tibbett. However, it is implemented differently and also uses different dummy videos that do not unnecessarily use CPU power.
