Add continuous deployment to firebase

[RyanMarten]

Edit react_app.yml to add this functionality. Should only deploy if it passes tests.

Automatic deployment when we push to master too?

adding comment to firebase deploy with the SHA of the git commit https://github.community/t5/GitHub-Actions/Accessing-commit-message-in-pull-request-event/td-p/40856

Using this github action to help out: https://github.com/marketplace/actions/github-action-for-firebase

Actually the answer was to install firebase-tools globally using npm install -g firebase-tools

Used my own action instead of the one that is out there --> the other one added 30 seconds of wait time.... not great

    - name: Install Firebase Tools
      run: npm install -g firebase-tools
      working-directory: app
    - name: Deploy to firebase
      working-directory: app
      run: firebase deploy --token $FIREBASE_TOKEN -m $SHA
      env:
        FIREBASE_TOKEN: ${{ secrets.FIREBASE_TOKEN }}
        SHA: ${{ github.sha}}
