Enhance Web Performance with the Scheduler API
The Scheduler API is a new web API that allows developers to schedule tasks with different priority levels, improving performance by preventing heavy tasks from blocking the main thread.
How the Scheduler API Works:
With scheduler.postTask(), developers can assign priority levels to tasks:
• "user-blocking" – Tasks that directly impact user interactions.
• "user-visible" – Tasks that update UI but are not critical.
• "background" – Low-priority tasks that run when the main thread is idle.
This approach prevents long-running tasks from freezing the UI.
Examples:
💡
The Scheduler API isn’t just about running tasks asynchronously—it’s about prioritizing execution on the main thread in a more controlled and efficient way. And, still is limited availability, so, is not yet available in all browsers.
