Deploying to Firebase Hosting

Standard Deployment

To deploy your Hosting content and configuration to your live site:

npx -y firebase-tools@latest deploy --only hosting

This deploys to your default sites (PROJECT_ID.web.app and PROJECT_ID.firebaseapp.com).

Preview channels allow you to test changes on a temporary URL before going live.

npx -y firebase-tools@latest hosting:channel:deploy CHANNEL_ID

Replace CHANNEL_ID with a name (e.g., feature-beta). This returns a preview URL like PROJECT_ID--CHANNEL_ID-RANDOM_HASH.web.app.

Channels expire after 7 days by default. To set a different expiration:

npx -y firebase-tools@latest hosting:channel:deploy CHANNEL_ID --expires 1d

You can promote a version from a preview channel to your live channel without rebuilding.

npx -y firebase-tools@latest hosting:clone SOURCE_SITE_ID:SOURCE_CHANNEL_ID TARGET_SITE_ID:live

Example: Clone the feature-beta channel on your default site to live:

npx -y firebase-tools@latest hosting:clone my-project:feature-beta my-project:live
