[Bug]: Fast Refresh had to perform a full reload. about serwist HOT 7 OPEN

@timohausmann no, let's keep it open. Dev mode is supported, and as such, we will need it to work properly. This clearly causes it to not.

@Xardasus if you use installSerwist + runtimeCaching like in basically any Next.js example in the docs, please disable runtimeCaching in development mode:

runtimeCaching: process.env.NODE_ENV === "development" ? undefined : defaultCache,

This feature can cause JS assets to be accidentally outdated, which is not something you want in development mode.

You may also clear the caches just in case.

In Serwist v9, runtimeCaching will be disabled by default in development mode, but this won't be backported to Serwist v8.

Hope this helps!

Many thanks @DuCanhGH, looks like it's working

Yeah this is an age-old issue, but I have not investigated it. Sounds like something is being unexpectedly cached, though.

It seems to only occur in dev, so maybe I could disable the SW in dev if I'm not working on it.

Since Next' preloading etc. behaves differently in dev mode, I found it best to only test the SW in production build.

const withSerwist = require("@serwist/next").default({
    swSrc: "./sw.ts",
    swDest: "public/sw.js",
    disable: process.env.NODE_ENV === 'development',
});

That solves the issue for me, feel free to close.

I get the same issue, also added disable: process.env.NODE_ENV === 'development',
running dev on Next.js 14.1 "dev": "next dev --experimental-https".
Something is getting cached and making it full reload, had to delete caches via the Dev tools.
