firebase-app-hosting-basics
Deploy and manage web apps with Firebase App Hosting. Use this skill when deploying Next.js/Angular apps with backends.
What this skill does
# 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.
1. 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"
]
}
}
```
2. Create or edit `apphosting.yaml`- see [Configuration](references/configuration.md) for more information on how to do so.
3. 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.
4. 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](references/cli_commands.md) for more information on how to set this up using CLI commands.
## Emulation
See [Emulation](references/emulation.md) for more information on how to test your app locally using the Firebase Local Emulator Suite.

IncludedLightning Web Components with PICKLES methodology and 165-point scoring. Use this skill when the user creates or edits LWC components, builds wire service patterns, or writes Jest tests for LWC. TRIGGER when: user creates/edits LWC components, touches lwc/**/*.js, .html, .css, .js-meta.xml files, or asks about wire service, SLDS, or Jest LWC tests. DO NOT TRIGGER when: Apex classes (use generating-apex), Aura components, or Visualforce.
tanstack-query
IncludedManage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.

IncludedProcess documents with Nutrient DWS. Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.
