Remove old service worker

Recently, I migrated a documentation page from Gatsby to Docusaurus. However, after I deployed a new version of the docs but I still see the cached version of the old docs. The reason is that the Gatsby version of the docs has a service worker that caches the artifacts. So, I need to remove the old service worker manually via Chrome Devtools.

However, this is not a good solution for all of my users. So, I decided to add a script to remove the old service worker. The script is as follows:

navigator?.serviceWorker?.getRegistrations().then(function (registrations) {
for (let registration of registrations) {


I put it inside an useEffect hook in a react component. Based on your framework, you can put it in the corresponding place.

I am not sure if this is the best solution. If you have a better solution, please let me know. Thanks a ton.
