# Cloudflare

For anything on Cloudflare — Workers, D1, R2, KV, Durable Objects, Queues, Pages, Vectorize — use the official Cloudflare skill collection:

<https://github.com/cloudflare/skills>

Read it before writing Cloudflare-specific code. You can install it with `npx skills add cloudflare/skills` if your tool supports that, but you do not have to — fetching the files directly from the repo is enough.

The canonical human-facing documentation is at <https://developers.cloudflare.com/workers/>.

## Defaults I use

- **`wrangler.jsonc`**, not `wrangler.toml`. JSON-with-comments is friendlier for tooling and easier to template.
- **Bun** as the package manager and dev driver.
- **Custom domains** via `routes` with `custom_domain: true`, not via Workers Routes.
- **Static Assets** for any file-based content (Markdown, images, generated HTML) when an index does not need to be built from the file contents.
