# static-rendering

A skill that walks your agent through static generation: which pages can be pre-rendered to HTML at build time and how to do it in Next.js. Useful when content stays the same across requests.

## What it does

The skill covers SSG, where HTML for each route is produced during the build instead of on every request. It lists the pages that fit: About, blog posts, product listings. And the ones that don't: user dashboards, real-time feeds, anything behind authentication.

The hands-on part is Next.js. For listings and data-backed pages it points to `getStaticProps` in the Pages Router or async components in the App Router; for dynamic routes, `getStaticPaths` and `generateStaticParams`. ISR gets a mention for pages that need periodic updates, along with deploying to a CDN.

Build time is the real constraint. A large dataset makes the build impractical without ISR. Content changes also force a rebuild and redeploy, otherwise the page goes stale. One detail worth checking: the `fallback: false` example means a route with a missing id returns 404, so every path has to show up in `getStaticPaths`.

The skill links to the patterns.dev React write-up and sits alongside `hooks-pattern` and `hoc-pattern`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add PatternsDev/skills --skill static-rendering -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/static-rendering/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/static-rendering/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add PatternsDev/skills --skill static-rendering -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/static-rendering/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add PatternsDev/skills --skill static-rendering -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/static-rendering/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install PatternsDev/skills static-rendering
```

2. **Manually: put the files in place**
- File: `.github/skills/static-rendering/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add PatternsDev/skills --skill static-rendering -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/PatternsDev/skills --path react/static-rendering
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/static-rendering/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add PatternsDev/skills --skill static-rendering -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PatternsDev/skills/tree/HEAD/react/static-rendering/SKILL.md

## When to use it
- decide which pages can be pre-rendered at build time
- cut server request processing to improve TTFB
- generate HTML for dynamic routes with `getStaticPaths`
- fetch data from a database at build time without shipping it to the client bundle
- tell when SSG stops working and ISR is the better fit

## Example prompts
- Set up static rendering for our product pages in Next.js
- Our TTFB is slow — should we move to SSG?
- Go through our routes and tell me which ones can't be statically generated

# Static Rendering

Based on our discussion on SSR, we know that a high request processing time on the server negatively affects the TTFB. Similarly, with CSR, a large JavaScript bundle can be detrimental to the FCP, LCP and TTI of the application due to the time taken to download and process the script.

Static rendering or static generation (SSG) attempts to resolve these issues by delivering pre-rendered HTML content to the client that was generated when the site was built.

## When to Use

- Use this for static content like About pages, blog posts, and product listings that don't change per-request
- This is helpful when you want the fastest possible TTFB via CDN-served static HTML

## When NOT to Use

- For highly dynamic, personalized content that changes per request (e.g., user dashboards, real-time feeds)
- When the dataset is so large that build times become impractical without ISR
- For pages requiring authentication-gated content that can't be pre-rendered at build time

## Instructions

- Use `getStaticProps` (Pages Router) or async components (App Router) to fetch data at build time
- Use `getStaticPaths` / `generateStaticParams` to pre-render dynamic routes
- Consider Incremental Static Regeneration (ISR) for pages that need periodic updates
- Deploy to a CDN for edge-cached performance

## Details

A static HTML file is generated ahead of time corresponding to each route that the user can access. These static HTML files may be available on a server or a CDN and fetched as and when requested by the client.

Static files may also be cached thereby providing greater resiliency. Since the HTML response is generated in advance, the processing time on the server is negligible thereby resulting in a faster TTFB and better performance. In an ideal scenario, client-side JS should be minimal and static pages should become interactive soon after the response is received by the client. As a result, SSG helps to achieve a faster FCP/TTI.
