How do I uninstall a Service Worker?
HtmlGoogle ChromeService WorkerHtml Problem Overview
After deleting /serviceworker.js
from my root directory, Chrome still runs the service worker that I removed from my webroot. How do I uninstall the service worker from my website and Chrome so I can log back into my website?
I've tracked the issue down to Service Work's cache mechanism and I just want to remove for now until I have time to debug it. The login script that I'm using redirects to Google's servers for them to login to their Google account. But all I get from the login.php page is an ERR_FAILED
message.

Removing Service Workers Programmatically
You can remove service workers programmatically like this:
navigator.serviceWorker.getRegistrations().then(function(registrations) {
for(let registration of registrations) {
registration.unregister()
} })
Docs: getRegistrations, unregister
Removing Service Workers Through The User Interface
You can also remove service workers under the Application tab in Chrome Devtools.
Solution 2 - Html
You can also go to the URL: chrome://serviceworker-internals/ and unregister a serviceworker from there.
Solution 3 - Html
You can do this through Chrome Developer Tool as well as Programatically.
- Find all running instance or service worker by typing
> chrome://serviceworker-internals/
in a new tab and then select the serviceworker you want to unregister.
- Open Developer Tools (F12) and Select Application. Then Either
> Select Clear Storage -> Unregister service worker
or
> Select Service Workers -> Choose Update on Reload
- Programatically
if(window.navigator && navigator.serviceWorker) {
navigator.serviceWorker.getRegistrations()
.then(function(registrations) {
for(let registration of registrations) {
registration.unregister();
}
});
}

In Google Chrome, you can go to Developer tools (F12) -> Application -> Service worker and unregister the service workers from the list for that specific domain.
This method is effective in development mode of a site and mostly they run on localhost
which is you may need for other project's development.

FYI, in case you are using MacOS Safari browser, there is one way to forcibly unregister a service worker (steps and images for Safari 12.1):
Note: In addition to service workers, this also will erase all caches, cookies, and databases for this domain.
Solution 6 - Html
You should detecte two API in your devices: getRegistrations and getRegistration. The service-worker not has a unique set of APIs in all platforms. For example, some browsers only have a navigator.serviceWorker.getRegistration
, no navigator.serviceWorker.getRegistrations
. So you should consider with both.

In addition to the already correct answers given, if you want also to delete the SW cache you can invoke the following method:
if ('caches' in window) {
caches.keys()
.then(function(keyList) {
return Promise.all(keyList.map(function(key) {
return caches.delete(key);
}));
})
}

Another possibility, via Browser, is by accessing the "Cache Storage" section and click on the "Clear Site Data" button:

safely uninstall Service Worker
if ('serviceWorker' in navigator) {
navigator.serviceWorker.getRegistrations().then(function (registrations) {
for (const registration of registrations) {
// unregister service worker
console.log('serviceWorker unregistered');
registration.unregister();
}
});
}
Solution 9 - Html
to detect service worker:
navigator.serviceWorker.controller
Code to for deletion of service worker:
navigator.serviceWorker.getRegistrations()
.then(registrations => {
registrations.forEach(registration => {
registration.unregister();
})
});
navigator.serviceWorker.getRegistrations().then(function(registrations) {
for(let registration of registrations) {
registration.unregister()
} })
if(window.navigator && navigator.serviceWorker) {
navigator.serviceWorker.getRegistrations()
.then(function(registrations) {
for(let registration of registrations) {
registration.unregister();
}
});
}
if ('caches' in window) {
caches.keys()
.then(function(keyList) {
return Promise.all(keyList.map(function(key) {
return caches.delete(key);
}));
})
}
if ('serviceWorker' in navigator) {
navigator.serviceWorker.getRegistrations().then(function (registrations) {
for (const registration of registrations) {
// unregister service worker
console.log('serviceWorker unregistered');
registration.unregister();
setTimeout(function(){
console.log('trying redirect do');
window.location.replace(window.location.href); // because without redirecting, first time on page load: still service worker will be available
}, 3000);
}
});
}

IF your service worker don't let you update your files. You will need to replace serviceworker file (sw.js / ServiceWorker.js) with the next code:
self.addEventListener('install', function(e) {
self.skipWaiting();
});
self.addEventListener('activate', function(e) {
self.registration.unregister()
.then(function() {
return self.clients.matchAll();
})
.then(function(clients) {
clients.forEach(client => client.navigate(client.url))
});
});

This code is compatible with Internet Explorer:
if (navigator.serviceWorker) {
navigator.serviceWorker.getRegistrations().then(
function(registrations) {
for (let idx in registrations) {
registrations[idx].unregister()
}
})
}
IE doesn't support 'for...of' and 'for...of' construction may lead to "'SCRIPT1004: Expected ';'" error

The other answers all add code to the live website to remove the service worker. However I didn't want to leave that live code running forever so I developed a solution that works from within the service worker itself. The steps are below, I posted more detail and explanation on my blog.
- Delete the code that registers the service worker.
- Replace the service worker script with the following file. The new code must be available from the same URL the previous service worker was at. If you had multiple service worker URLs in the past you should duplicate the code at all of them.
console.log("Cleanup Service Worker Starting");
caches.keys()
.then(keys =>
Promise.all(
keys.map(async key => console.log("caches.delete", key, await caches.delete(key)))))
.then(async () => {
console.log("registration.unregister", await registration.unregister());
})
.then(() => console.log("DONE"))
.catch(console.error);
This code is fairly straight forward. First it deletes all the caches, then it unregisters itself.
Users' browsers will automatically check for an updated service worker the next time they load your website, or the next event 24h after the last service worker check. This means that existing users will run this cleanup on their next visit.

as for me , i just use a new nonexistent scope service worker to replace old one,
ServiceWorker: {
events: true,
// what range of URLs a service worker can control. Use a nonexistent path to disable ServiceWorker
scope: '/disable-service-worker/',
},
as for the app.js, i add below code to unregister old sw:
if ('serviceWorker' in navigator) {
navigator.serviceWorker.getRegistrations().then(registrations => {
for (const registration of registrations) {
// keep only serviceWorker which scope is /disable-service-worker/, The purpose is to make serviceWorker useless
if (registration.scope.includes('/disable-service-worker/') === false) {
registration.unregister()
}
}
});
// clear cache of service worker
caches.keys().then(keyList => {
return Promise.all(
keyList.map(key => {
return caches.delete(key);
}),
);
});
}
