screen-wake-lock

screen-wake-lock.js

React library to prevent device from entering sleep mode when app is in active tab.

Installation

# Install using npm
npm install screen-wake-lock

# Install using yarn
yarn add screen-wake-lock

Usage

Prevent device from entering sleep app-wide using WakeLock component

import React from 'react';
import ReactDOM from 'react-dom';
import WakeLock from 'screen-wake-lock';
import App from './App';

ReactDOM.render(
  <React.StrictMode>
    <WakeLock />
    <App />
  </React.StrictMode>,
  document.getElementById('root'),
);

Prevent device from entering sleep mode when a specific component is rendered using WakeLock component

import React from 'react';
import WakeLock from 'screen-wake-lock';

const SpecificComponent = () => {
  return (
    <>
      <WakeLock />
      <div>Sleepless in Seattle</div>
    </>
  );
};

export default SpecificComponent;

Prevent device from entering sleep mode when a specific component is rendered using useWakeLock hook

import React from 'react';
import { useWakeLock } from 'screen-wake-lock';

const SpecificComponent = () => {
  useWakeLock();
  return <div>Sleepless in Seattle</div>;
};

export default SpecificComponent;

Use useWakeLock in debug mode

useWakeLock takes an optional parameter debug. When passed true it will print the status of the wake lock to the console whenever it gets locked or released. for instance when navigating away from the browser tab where the app is running and back. This can be a convenient way to test that the hook is working.

import React from 'react';
import { useWakeLock } from 'screen-wake-lock';

const SpecificComponent = () => {
  useWakeLock(true);
  return <div>Sleepless in Seattle</div>;
};

export default SpecificComponent;

// Screen Wake Lock released: true
// Screen Wake Lock released: false
