Service worker

Meaning in software engineering, with examples

nounAdvanced term

In software engineering, service worker means: A browser-managed script that runs separately from a page and can handle events such as network requests for controlled pages.

In Turkish: servis işçisi

How it is used

Used for offline behavior, caching and background events. It does not have direct access to the page's DOM.

Example sentences

  1. The service worker returned a cached article when the phone lost its connection.

    The request can be answered locally rather than failing with the network.

  2. An outdated service worker kept serving the previous stylesheet until its cache was refreshed.

    Cached responses need an update strategy to avoid retaining obsolete assets.

Common collocations

  • register a service worker
  • service worker lifecycle
  • cacheA place where copies of files or data are kept for a while so they can be served again faster, for example in the browser, on a CDN or on the server.
  • offline modeA way of working in which an app stays usable without an internet connection, showing saved data and sending changes later when the connection returns.
