# Setting up Firebase Hosting with an is-a.dev Subdomain

This guide will walk you through the process of setting up a Firebase Hosting site and pointing your is-a.dev subdomain towards it.

# Creating a Firebase Project

First, create a Firebase project and set up Firebase Hosting. Follow the instructions in the Firebase Hosting Documentation.

# Setting up Firebase Hosting

Install the Firebase CLI: npm install -g firebase-tools
Initialize Firebase in your project directory: firebase init hosting
Deploy your site: firebase deploy

# Creating the Domain File

Create a JSON file inside the domains directory (domains/subdomain.json) with the following content and submit a pull request:

{
  "owner": {
    "username": "github-username",
    "email": "me@example.com"
  },
  "records": {
    "CNAME": "your-firebase-site.web.app"
  }
}

Make sure to replace:

github-username with your actual GitHub username
me@example.com with your email address
your-firebase-site.web.app with your hosting site

# Configuring Firebase Hosting for Custom Domain

After your pull request is merged and your is-a.dev subdomain is active:

Go to your Firebase Console
Navigate to Hosting in the left sidebar
Click Add custom domain
Enter your is-a.dev subdomain (e.g., example.is-a.dev)
Firebase will verify domain ownership automatically through DNS
Wait for the SSL certificate to be provisioned (this can take up to 24 hours)

# Notes

Firebase Hosting automatically provides SSL certificates for custom domains
Make sure your Firebase project is deployed and accessible before adding the custom domain

# Troubleshooting

If you encounter issues:

Ensure your Firebase project is deployed and accessible via the default .web.app domain
Check that your DNS records have propagated (this can take up to 48 hours)
Verify your Firebase Hosting configuration in firebase.json
Make sure your build files are in the correct public directory specified in your Firebase configuration
