The imperative shape of I spent a little too long with testing and ai making sure it was the most performant structure. It's not unnecessary boilerplate. |
The inline deletions are tracked directly instead of checked through the filesystem, so the helper no longer touches the disk at all.

#16372 added the
_app/immutablefilter when computing$app/manifest'simmutable, but the serviceWorker environment kept the unfiltered file set it inherited from$service-worker'sbuild. That copy includes_app/manifest.js, whose filename never changes, so a service worker that cachesimmutableper the docs serves the previous deployment's manifest after a redeploy. Both lists are now computed by one helper; thebundleStrategy: 'inline'special case is subsumed by its existence check.The truthiness checks on
css/assetsmake the helper robust to the full range of Vite's optionalcss?: string[]field, so a hypotheticalcss: nullentry is skipped cleanly instead of crashing the build.The client-side list was also computed before the
bundleStrategy: 'inline'deletions it was supposed to reflect, so the page'simmutableincluded the deleted bundle and stylesheet while the service worker's, computed after them, did not. The inlined files are now tracked directly and excluded everywhere, instead of checking the filesystem after the fact._app/manifest.jsis no longer precached, so an offline-first app that imports$app/manifestin client code only has it cached once a page has fetched it. The precached copy was guaranteed stale after the next deploy anyway; moving the chunk toassets, as floated in #16372, would give such apps a correct offline copy.
