Firebase App Hosting Basics

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

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.json with an apphosting block.

   {
     "apphosting": {
       "backendId": "my-app-id",
       "rootDir": "/",
       "ignore": [
         "node_modules",
         ".git",
         "firebase-debug.log",
         "firebase-debug.*.log",
         "functions"
       ]
     }
   }

• Create or edit apphosting.yaml- see

Configuration for more information on how to

do so.

• If the app needs safe access to sensitive keys, use

npx -y firebase-tools@latest apphosting:secrets commands to set and grant

access to secrets.

• Run npx -y firebase-tools@latest deploy when 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 for more information on how to set

this up using CLI commands.

Emulation

See Emulation for more information on how to test

your app locally using the Firebase Local Emulator Suite.
