Firebase hosting rewrites not working

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.10 Ara 2015

So, anyone who knows the URL can access it.

Before you can set up Firebase Hosting, you need to create a Firebase project.
