# setup-cdn-optimization A slash command that walks your agent through CDN configuration: caching, compression, image formats and cache invalidation. - command · `type=command` · Claude Code · 218 installs - Author: davila7 - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/davila7/claude-code-templates/tree/HEAD/cli-tool/components/commands/performance/setup-cdn-optimization.md - Updated: 2026-10-24 - HTML: https://affpapa.org/en/nevibecode/commands/setup-cdn-optimization ## What it does \`setup-cdn-optimization` is a Claude command that turns CDN setup into a ten-step checklist. The agent starts with traffic patterns and user distribution, picks a provider, then plans the edge architecture. Next come origin servers, failover, SSL/TLS certificates, custom domain and DNS. A large part of the command covers static assets and caching: content hashing, bundling, code splitting, `Cache-Control` headers and TTL values, ETags, multi-tier caching and cache warming. Compression gets its own steps for Gzip and Brotli, plus WebP and AVIF delivery with fallbacks and lazy loading. Cache invalidation is covered too, including automated purging in deployment pipelines and selective purging by tags or patterns. You can name the provider as an argument: `--cloudflare`, `--aws` or `--fastly`. The command runs with `Read`, `Bash`, `Grep` and `Glob` only, so it reads and searches your files but never edits them. Expect to apply the config changes yourself in the provider dashboard. If the domain is not pointed at the CDN yet, the DNS and certificate steps have nothing to work with. ## Requirements - Works with: AWS ## Install ### Claude Code (native platform) 1. **claude-code-templates** ```bash npx claude-code-templates@latest --command performance/setup-cdn-optimization ``` 2. **Manually: put the files in place** - File: `.claude/commands/setup-cdn-optimization.md` — Call it with /setup-cdn-optimization. For all projects use ~/.claude/commands/ ### Codex **Manually: put the files in place** - File: `~/.codex/prompts/setup-cdn-optimization.md` — Call it with /prompts:setup-cdn-optimization. Codex marks this format deprecated in favour of skills ### GitHub Copilot **Manually: put the files in place** - File: `.github/prompts/setup-cdn-optimization.prompt.md` ### Gemini CLI **Manually: put the files in place** - File: `.gemini/commands/setup-cdn-optimization.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field Where a file is given instead of a command, copy the files from the source to that path: https://github.com/davila7/claude-code-templates/tree/HEAD/cli-tool/components/commands/performance/setup-cdn-optimization.md ## When to use it - pick a CDN provider that fits your content types and user regions - set cache headers and TTL values per asset type - turn on Gzip and Brotli for static files and API responses - serve images as WebP and AVIF with fallbacks - purge the cache automatically on every deploy ## Example prompts - set up a CDN for this project, provider --cloudflare - run setup-cdn-optimization and propose a caching policy for static assets - work out Cache-Control headers for images and fonts ## Source text · setup-cdn-optimization.md · MIT Below is the content of a third-party file.
