Use\n  when the user needs to deploy a static site, set up a React/Vue/Hugo/Gatsby\n  frontend, configure SPA fallback routing, add redirect rules, customize\n  response headers, or choose between a static site and a web service for\n  their frontend.\n  Trigger terms: static site, CDN, SPA, single-page app, React deploy,\n  Vue deploy, Hugo, Gatsby, Docusaurus, Jekyll, staticPublishPath.\nlicense: MIT\ncompatibility: Render static sites (free tier available)\nmetadata:\n  author: Render\n  version: \"1.0.0\"\n  category: compute\n---\n\n# Render Static Sites\n\nDeploys static frontends (React, Vue, Hugo, Gatsby, Docusaurus, Jekyll, etc.) to Render's global CDN with automatic TLS, Brotli compression, HTTP/2, and DDoS protection. Free tier available.\n\n## When to Use\n\n- Deploying a **static site or SPA** (no server-side rendering)\n- Choosing between a **Static Site** and a **Web Service** for a frontend\n- Configuring **SPA fallback routing**, **redirects/rewrites**, or **custom headers**\n- Setting up **PR preview environments** for a static site\n- Troubleshooting **build failures** or **stale content** on a CDN-hosted site\n\nFor SSR frameworks (Next.js, Nuxt, SvelteKit) that need a running server, use **render-web-services** instead. For Blueprint authoring, see **render-blueprints**.\n\nWhen choosing between a static site and a web service, read `references/service-types.md`.\n\n## Static Site vs Web Service\n\n| Need | Use | Why |\n|------|-----|-----|\n| Pure HTML/CSS/JS, SPA, docs, blog | **Static Site** | Free, global CDN, instant cache invalidation |\n| SSR (Next.js `next start`, Nuxt server) | **Web Service** | Needs a running Node/Python/etc. process |\n| Static export from SSR framework | **Static Site** | If the framework supports full static export (`next export`, `nuxt generate`) |\n| API backend | **Web Service** | Static sites cannot run server code |\n\n**Key constraint:** Static sites are **not on the private network**. They cannot communicate with other Render services over internal hostnames.\n\n## Build and Publish\n\n| Setting | Purpose |\n|---------|---------|\n| `buildCommand` | Installs dependencies and builds assets (e.g. `npm ci && npm run build`) |\n| `staticPublishPath` | Directory of built output to serve (e.g. `build`, `dist`, `public`) |\n\nRender auto-detects and installs dependencies. Set `SKIP_INSTALL_DEPS=true` to handle installation yourself in the build command.\n\n### Common frameworks\n\n| Framework | Build command | Publish path |\n|-----------|--------------|--------------|\n| Create React App | `npm ci && npm run build` | `build` |\n| Vite (React/Vue/Svelte) | `npm ci && npm run build` | `dist` |\n| Next.js (static export) | `npm ci && next build` | `out` |\n| Nuxt (static) | `npm ci && nuxt generate` | `.output/public` |\n| Hugo | `hugo --minify` | `public` |\n| Gatsby | `npm ci && gatsby build` | `public` |\n| Docusaurus | `npm ci && npm run build` | `build` |\n| Jekyll | `bundle exec jekyll build` | `_site` |\n| Astro | `npm ci && astro build` | `dist` |\n\n## SPA Routing and Redirects\n\nSingle-page apps need a catch-all rule so the CDN serves `index.html` for all routes instead of returning 404.\n\nConfigure **Redirect/Rewrite Rules** in the Dashboard (Settings > Redirects/Rewrites) or via the Blueprint `routes` field:\n\n```yaml\nroutes:\n  - type: rewrite\n    source: /*\n    destination: /index.html\n```\n\nFor multi-path redirects (e.g. old blog URLs), add specific rules **above** the catch-all so they take priority.\n\nSee `references/routing-and-headers.md` for redirect types, header rules, and caching patterns.\n\n## Custom Response Headers\n\nAdd security and performance headers from the Dashboard (Settings > Headers) or the Blueprint `headers` field:\n\n```yaml\nheaders:\n  - path: /*\n    name: X-Frame-Options\n    value: DENY\n  - path: /assets/*\n    name: Cache-Control\n    value: public, max-age=31536000, immutable\n```\n\n## PR Previews\n\nStatic sites support automatic PR previews—each pull request gets a unique URL with the built site.\n\n- Enable in Dashboard: Settings > PR Previews\n- Blueprint: set `previews.generation` to `automatic` or `manual`\n- Preview URLs follow the pattern `<service>-<pr-id>.onrender.com`\n\n## Blueprint Configuration\n\n```yaml\nservices:\n  - type: web\n    runtime: static\n    name: my-frontend\n    buildCommand: npm ci && npm run build\n    staticPublishPath: dist\n    routes:\n      - type: rewrite\n        source: /*\n        destination: /index.html\n    headers:\n      - path: /*\n        name: X-Frame-Options\n        value: DENY\n    previews:\n      generation: automatic\n```\n\n**Note:** Static sites use `type: web` with `runtime: static` in Blueprints. There is no separate `type: static`.\n\n## CDN and Performance\n\n- **Global CDN** with edge caching worldwide\n- **Brotli compression** (better than gzip)\n- **HTTP/2** by default\n- **Immediate cache invalidation** on every deploy (zero-downtime, atomic deploys)\n- **DDoS protection** included\n\n## Billing\n\nStatic sites have a **free tier**. They count against workspace-level monthly included amounts for:\n\n- **Outbound bandwidth** (data served to users)\n- **Pipeline minutes** (build time)\n\nUsage beyond included allowances can incur additional cost. Confirm current allowances and charges at [Render pricing](https://render.com/pricing).\n\n## References\n\n| Document | Contents |\n|----------|----------|\n| `references/routing-and-headers.md` | Redirect types, rewrite rules, header patterns, SPA config |\n| `references/framework-configs.md` | Build commands and publish paths for 10+ frameworks |\n| `references/service-types.md` | Service-type selection and execution models |\n\n## Related Skills\n\n- **render-web-services** — For SSR frameworks that need a running server\n- **render-blueprints** — Full `render.yaml` schema for static site fields\n- **render-domains** — Custom domain and TLS setup\n- **render-deploy** — Deploy flows, CLI, MCP operations\n\n<!-- shared:documentation-retrieval -->\n## Current documentation retrieval\n\nWhenever this skill directs you to consult current Render documentation:\n\n1. Retrieve the linked Markdown document directly with an available URL-fetching tool or HTTP client, such as `curl`. Do not substitute web-search summaries for the document.\n2. Confirm that retrieval succeeded and returned the expected document, then read its contents. Saving a file or printing its path is not sufficient.\n3. If the request fails or your tool cannot read the Markdown response, open and read the linked HTML version instead.\n4. If neither version can be retrieved, disclose that the current reference is unavailable and follow any topic-specific fallback in the skill. Use bundled guidance only for stable constraints, and do not guess at changeable platform details.\n\nWhen a task requires multiple references, apply this workflow to each one and distinguish the documents you verified from those that remain unavailable.\n<!-- /shared:documentation-retrieval -->\n"
