The W3C Service Workers specification repository, defining event-driven browser scripts that run independently of web pages and enable offline-capable web applications. It contains the living Editor's Draft (Nightly) and the Service Workers 1 spec advancing toward W3C Recommendation, written in Bikeshed.

Use cases

• understand how service workers enable offline web apps
• look up the fetch event and Cache API semantics
• implement service worker support in a browser engine
• file spec issues or contribute edits to the service worker standard
• learn how service workers replace HTML5 AppCache
• find use cases and examples for service worker features

When to choose

• you need the authoritative normative definition of the Service Worker API
• you are a browser implementer or spec contributor
• you want to track the latest nightly features or v1 recommendation status

When to avoid

• you want a ready-to-use JavaScript library or polyfill for service workers
• you need beginner tutorials rather than formal specification text
• you are looking for runnable application code
