App Hosting Basics
Description
This skill enables the agent to deploy and manage modern, full-stack web applications (Next.js, Angular, etc.) using Firebase App Hosting.
Important: In order to use App Hosting, your Firebase project must be on the Blaze pricing plan. Direct the user to https://console.firebase.google.com/project/_/overview?purchaseBillingPlan=metered to upgrade their plan.
Hosting vs App Hosting
Choose Firebase Hosting if:
- You are deploying a static site (HTML/CSS/JS).
- You are deploying a simple SPA (React, Vue, etc. without SSR).
- You want full control over the build and deploy process via CLI.
Choose Firebase App Hosting if:
- You are using a supported full-stack framework like Next.js or Angular.
- You need Server-Side Rendering (SSR) or ISR.
- You want an automated "git push to deploy" workflow with zero configuration.
Deploying to App Hosting
Deploy from Source
This is the recommended flow for most users.
-
Configure
firebase.jsonwith anapphostingblock. -
Create or edit
apphosting.yaml- see Configuration [blocked] for more information on how to do so. -
If the app needs safe access to sensitive keys, use
npx -y firebase-tools@latest apphosting:secretscommands to set and grant access to secrets. -
Run
npx -y firebase-tools@latest deploywhen you are ready to deploy.
Automated deployment via GitHub (CI/CD)
Alternatively, set up a backend connected to a GitHub repository for automated deployments "git push" deployments. This is only recommended for more advanced users, and is not required to use App Hosting. See CLI Commands [blocked] for more information on how to set this up using CLI commands.
Emulation
See Emulation [blocked] for more information on how to test your app locally using the Firebase Local Emulator Suite.
