Install the Firebase CLI if you haven’t already by running npm install -g firebase-tools. Sign up for a Firebase account and create a new project. Run firebase login and login with your previous created Firebase account.
Then run the firebase init command from your project’s root. You need to choose the Hosting: Configure and deploy Firebase Hosting sites and choose the Firebase project you created in the previous step. You will need to agree with database.rules.json being created, choose build as the public directory, and also agree to Configure as a single-page app by replying with y.
=== Project Setup
First, let's associate this project directory with a Firebase project.
You can create multiple project aliases by running firebase use --add,
but for now we'll just set up a default project.
? What Firebase project do you want to associate as default? Example app (example-app-fd690)
=== Database Setup
Firebase Realtime Database Rules allow you to define how your data should be
structured and when your data can be read from and written to.
? What file should be used for Database Rules? database.rules.json
✔ Database Rules for example-app-fd690 have been downloaded to database.rules.json.
Future modifications to database.rules.json will update Database Rules when you run
firebase deploy.
=== Hosting Setup
Your public directory is the folder (relative to your project directory) that
will contain Hosting assets to uploaded with firebase deploy. If you
have a build process for your assets, use your build's output directory.
? What do you want to use as your public directory? build
? Configure as a single-page app (rewrite all urls to /index.html)? Yes
✔ Wrote build/index.html
