firebase-app-hosting-basics

Deploys and manages full-stack web applications (Next.js, Angular) with Server-Side Rendering (SSR) using Firebase App Hosting. Use when deploying Next.js/Angular apps, configuring apphosting.yaml or firebase.json apphosting blocks, managing secrets, setting up GitHub CI/CD, or configuring Blaze billing requirements. Don't use for classic static web hosting, Auth, Firestore, Crashlytics, or Xcode.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
3 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by firebase on GitHub. Read the source before you install it.

Installation

Install the Firebase App Hosting Basics AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/firebase/agent-skills/tree/main/skills/firebase-app-hosting-basics
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/firebase/agent-skills.git /tmp/agent-skills
mkdir -p .claude/skills
cp -r /tmp/agent-skills/skills/firebase-app-hosting-basics .claude/skills/firebase-app-hosting-basics

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Firebase App Hosting Basics in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Firebase App Hosting Basics on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Firebase App Hosting Basics is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

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.json with an apphosting block.

json
{
  "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.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Firebase App Hosting Basics AI skill do?

Why use Firebase App Hosting Basics on TypingMind?

Because you install it once and use it with any model. Firebase App Hosting Basics is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Firebase App Hosting Basics in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/firebase/agent-skills/tree/main/skills/firebase-app-hosting-basics. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Firebase App Hosting Basics?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Firebase App Hosting Basics?

As many as you like. As long as a model supports skills, you can use Firebase App Hosting Basics with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Firebase App Hosting Basics AI skill free?

Yes. It is published on GitHub by firebase under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
