Runtime caching caches at second reload

[ProDeSquare]

I'm using vite-plugin-pwa with my React.js, Typescript, and SWC app. I've noticed in the dev tools it doesn't cache my API requests until the second reload. I tried a solution from this link (from StackOverflow) but it didn't help. I implemented this with:

workbox: {
    clientsClaim: true,
    skipWaiting: true
}

but it still caches the API response on the second reload. I also tried dns-prefetch and preconnect (according to the official documentation) with the API host but it had no effect. Is there any workaround for that, I'm using the GenerateSW method.

@ProDeSquare can you try this https://github.com/GoogleChrome/workbox/issues/1415#issuecomment-382458870 ? You'll need to use any of the virtual modules calling the useRegisterSW (fw ones) or registerSW (vanilljs)

This is the registerSW.js code, it already has an event listener on window load which registers the sw.js

if('serviceWorker'in navigator){window.addEventListener('load',()=>{navigator.serviceWorker.register('/sw.js',{scope:'/'})})}

Should I delay it even further?

Edit: I've started seeing the pattern. My API requests are lazy loaded.

For testing: Now my API requests are delayed 5 seconds after the page load.

Result:

1. Page Loads and service worker gets registered
2. 5 seconds later API requests are made and nothing is added to the cache
3. Waited a couple of seconds to check if the API response is cached and it doesn't
4. The page is refreshed and after 5 seconds the API is called again and this time it's added to the cache
