# Astro Deployment

Production deployment for Astro 6 across all major platforms — Cloudflare, Vercel, Netlify, and Node.js.

## Agent Workflow (MANDATORY)

Before ANY implementation, use `TeamCreate` to spawn 3 agents:

1. **fuse-ai-pilot:explore-codebase** - Analyze astro.config.mjs, output mode, and existing adapter
2. **fuse-ai-pilot:research-expert** - Verify adapter docs via Context7/Exa for target platform
3. **mcp__context7__query-docs** - Check Astro 6 adapter compatibility and breaking changes

After implementation, run **fuse-ai-pilot:sniper** for validation.

## Overview

### When to Use

- Deploying Astro to Cloudflare Workers with D1/KV/R2 bindings
- Configuring Vercel Serverless or Edge runtime with image CDN
- Setting up Netlify Edge Functions
- Running Astro as standalone Node.js server
- Implementing ISR (Incremental Static Regeneration) patterns
- Configuring edge middleware for auth/redirects

### Adapter Matrix

| Platform | Package | Runtime | Notes |
|----------|---------|---------|-------|
| Cloudflare | `@astrojs/cloudflare` v13+ | workerd | Astro 6: `astro dev` runs on workerd |
| Vercel | `@astrojs/vercel` | Node/Edge | Image CDN built-in |
| Netlify | `@astrojs/netlify` | Edge | Deno-based edge functions |
| Node.js | `@astrojs/node` | Node | Standalone server mode |

---

## Core Concepts

### Output Modes

- `output: 'static'` — Full SSG, no adapter needed
- `output: 'server'` — Full SSR, adapter required
- Per-page: Mix with `export const prerender = true/false`

### Cloudflare Astro 6

Astro 6 runs `astro dev` on workerd — same runtime as production. Enables D1, KV, R2 bindings in local dev via `platformProxy`. No more simulation gaps. Requires `@astrojs/cloudflare` v13+ and Node.js 22+.

### ISR Pattern

Astro has no native ISR. Implement with platform caching: Cloudflare KV as cache layer, or Vercel's `Cache-Control` with `stale-while-revalidate`.

### Skew Protection

On Vercel, enable skew protection to prevent asset mismatches between old client and new server during deployments.

## Best Practices

1. **Match adapter to platform early** - Switching adapters mid-project is painful
2. **Cloudflare: use v13+ for Astro 6** - Required for workerd local dev
3. **Node.js 22+ for Astro 6** - Drops Node 18/20 support
4. **Per-page prerender** - Mix static and SSR for optimal performance
5. **Test bindings locally** - Cloudflare platformProxy enables local D1/KV/R2
