`files` in `$service-worker` should contain prerendered files

[frederikhors]

Using adapter-static and the code:

import { files } from '$service-worker';

I expect to find also the <NAME>.html fallback file listed in files.

Am I wrong?

Please provide a complete and minimal reproducible example of what happen and should've happen.

this is specific for adapter, so it's not good if it's provided by $service-worker, why You don't simply add manually that file to it? It's just one line of code.

For fallback we can add just the one. For prerendered files there might be too many to do this. We'd have to have the adapter generate the manifest after prerendering I guess? Or maybe we can somehow do SSG during Vite build, which I think vitepress might do

@frederikhors The problem is that any adapter used is called after svelte finish build process, so calling/building the service worker module cannot have those files.

@benmccann vitepress right now has not pwa support: you can see how I regenerate the vite-plugin-pwa docs using vitepress and executing again the pwa build process for build it (on build script on docs package.json file), that is, after vitepress build finish.

I have a branch on my fork of vitepress with the build module using the vite-plugin-pwa api like the svelte kit one (on my fork):

• https://github.com/userquin/kit/blob/feat/add-vite-plugin-pwa/packages/kit/src/cli.js#L108 and https://github.com/userquin/kit/blob/feat/add-vite-plugin-pwa/packages/kit/src/cli.js#L145
• https://github.com/userquin/vitepress/blob/feat/pwa-support/src/node/build/build.ts#L16, https://github.com/userquin/vitepress/blob/feat/pwa-support/src/node/build/build.ts#L81 and https://github.com/userquin/vitepress/blob/feat/pwa-support/src/node/build/pwa.ts

@ignatiusmb you can build and preview the https://github.com/svelte-society/sveltesociety.dev: before building it, just add a service worker file and log the files entry from service worker module.

You can see the expected output on this branch on my fork of svelte-society, using the vite-plugin-pwa, just build the project and see sw.js generated file from vite-plugin-pwa: https://github.com/userquin/sveltesociety.dev.

On following screenshot, all these pages (there are a lot more) are missing from the service worker module (and for that reason, apps using service worker module cannot run on offline: if you preview my master branch fork, all pages will work on offline).

[benmccann]

SvelteKit's own service worker should contain prerendered files now. Unfortunately, it still doesn't happen early enough in the build process that plugins like vite-plugin-pwa could pick them up
