How to edit my static site in firebase hosting

I'm starting with Firebase Hosting, I made a static website with some Javascript elements. I have a simple question that I did not find clear information in the Firebase documentation: how would I edit my static site? Whether to change some information, or upload a new page? Do I deploy all over again like the first time I uploaded the site?

Solution

To make changes to a deployed Firebase Hosting website, you should make the necessary changes to your local copy and then run firebase deploy again.

Each time you run firebase deploy after making a change, the following steps (amongst others) are performed automatically:

The version number is incremented
The current version becomes the previous version (and so on)
All changed files are uploaded
The changes are made live

This is useful because the full history of your deploys are kept on Firebase Hosting so that you can rollback to a previous version should you need to.
