NoSleep.js

Prevent display sleep and enable wake lock in all Android and iOS web browsers.

Check out the live demo in any Android or iOS web browser.

Installation

This library is available on Bower as nosleep.

bower install nosleep

This package is published to npm as nosleep.js and can be installed with:

npm install nosleep.js

Alternatively, you can manually add NoSleep.js to your project (or the minified version).

Build from source

Install all development dependencies with:

npm install

To build this library run:

npm run build

A new build of NoSleep.js and NoSleep.min.js will now be available in the /dist directory.

Usage

Create a new NoSleep object and then enable or disable it when needed.

To create a new NoSleep object:

var noSleep = new NoSleep();

To enable wake lock:

NOTE: This function call must be wrapped in a user input event handler e.g. a mouse or touch handler

// Enable wake lock.
// (must be wrapped in a user input event handler e.g. a mouse or touch handler)
document.addEventListener('click', function enableNoSleep() {
  document.removeEventListener('click', enableNoSleep, false);
  noSleep.enable();
}, false);

To disable wake lock:

// Disable wake lock at some point in the future.
// (does not need to be wrapped in any user input event handler)
noSleep.disable();

See example/index.html (and the live demo) for more information.
