Firebase deploy not updating JS file

I had same issue and I did clear the cache and everything but I still had the same problem, then run

yarn build

Then I could see my latest changes.

If you're using React or Vue, do not forget to run the build command like npm run build before running the command firebase deploy

If the deploy is successful, this is likely a caching issue.

You can try pressing cmd+shift+R (ctrl+shift+R on Windows) to do a hard refresh of the cache.

Try going to the file's URL directly (https://<my-app>.web.app/app.js), and do a hard refresh. You should see it update to what you have locally.

With Chrome, you can have the cache disable when DevTools are open by selecting the "Disable cache" option in the Network tab.

make sure you're building any new changes you've made before deploying.

For example if you have an angular 2 application and are using the angular cli type ng build then firebase deploy.

To clear cache press Ctr+F5 or better use incognito Mode for Development. using Incognito Mode for force reload works well for Mobile as well as desktop.
