Vue Router History Mode with PWA in Offline Mode

You need to set the navigateFallback option in your vue.config.js file:

pwa: {  workboxOptions: {    navigateFallback: 'index.html'  }}

It will automatically add the necessary code to your service worker:

workbox.routing.registerNavigationRoute(workbox.precaching.getCacheKeyForURL("index.html"));

I had the same problem and I found the solution here: https://github.com/vuejs/vue-cli/issues/717#issuecomment-382079361

If your site is a single page app, you can use a NavigationRoute to return a specific response for all navigation requests.

workbox.routing.registerNavigationRoute('/single-page-app.html')

In my case in vue :

workbox.routing.registerNavigationRoute('/index.html')

Whenever a user goes to your site in the browser, the request for the page will be a navigation request and will be served the cached page /single-page-app.html.

Note: You should have the page cached via workbox-precaching or through your own installation step).

By default, this will respond to all navigation requests, if you want to restrict it to respond to a subset of URL’s you can use the whitelist and blacklist options to restrict which pages will match this route.

Update: Workbox V5

const handler = workbox.precaching.createHandlerBoundToURL("/index.html");const navigationRoute = new workbox.routing.NavigationRoute(handler);workbox.routing.registerRoute(navigationRoute);
