How to clear cache of service worker?

Question

So, I have an HTML page with service worker, the service worker cache the index.html and my JS files.

The problem is when I change the JS, the change doesn't show up directly on the client browser. Of course in chrome dev-tools, I can disable cache. But in chrome mobile, how do I do that?

I tried to access the site settings and hit the CLEAR % RESET button. But it still loads the old page/load from cache. I tried to use other browser or chrome incognito and it loads the new page.

Then, I try to clear my browsing data (just cache) and it works.

I guess that's not how it should work right? my user won't know if the page is updated without clearing the chrome browser cache.

If you know the cache name you can simply call caches.delete() from anywhere you like in the worker:

caches.delete(/*name*/);

And if you wanted to wipe all caches (and not wait for them, say this is a background task) you only need to add this:

caches.keys().then(function(names) {
    for (let name of names)
        caches.delete(name);
});
