• Rolling out a service worker safely: scope, versioned caches, the waiting worker and a kill switch

  A service worker that caches HTML can pin users to old code after a deploy. Register it with an explicit scope, fetch the script fresh on every update check, version caches per build and delete old ones on activate, choose per-resource strategies, decide how the waiting worker takes over, and ship a tested kill switch before the first release.
