NoSleep.js is a small JavaScript library that prevents the display from sleeping and enables wake lock in Android and iOS web browsers. It wraps the Wake Lock API with fallbacks so web apps can keep the screen on during playback or other long-running interactions.

Use cases

• keep the screen on while a web app plays video or audio
• prevent display sleep during a mobile web game
• hold wake lock while showing a recipe or workout in the browser
• stop the screen dimming during a long-running web-based presentation
• enable wake lock after a user tap in a mobile web app

When to choose

• you need to keep a mobile browser screen awake on Android or iOS
• you want a tiny dependency with a simple enable/disable API
• you need fallback behavior for browsers without the native Wake Lock API

When to avoid

• you are building a native mobile app rather than a web app
• you only target desktop browsers where screen sleep is managed differently
• you need a maintained solution with active development and frequent releases
