Contributing

Want to add an example? Read CONTRIBUTING.md — it is a step-by-step guide covering the required example layout, how to deploy via Databricks Asset Bundles, and how to document your example so it appears on the cookbook site.

The essentials:

• Resources related to your example must be deployable via Databricks Asset Bundles
• Keep database configurations small to reduce spend
• Use uv as the package manager
• Use ruff as the linter

Documentation site

This repo also publishes a documentation site hosted on Cloudflare Workers at https://lakebase-cookbook.com. The site is built with Astro; the source lives in site/, and common tasks are wrapped in the Makefile (run make help to list them).

You can preview and contribute to the site without any Cloudflare account or credentials:

make install    # one-time: install site dependencies
make dev        # local dev server with hot reload at http://localhost:3000
make build      # build the static site into site/dist (verifies the build)

To add or edit content:

• Docs / examples — add or edit Markdown in site/src/content/docs/. New files under examples/ automatically appear in the sidebar. See CONTRIBUTING.md for the exact frontmatter and layout.
• Blog posts — add Markdown to site/src/content/blog/.
• Landing page / styling — site/src/ (Astro pages, React islands, and CSS design tokens in site/src/styles/global.css).
• Navbar, footer, site config — site/src/config.ts.

Then open a pull request. Deploys are handled by a maintainer after merge and require Cloudflare credentials that are not stored in this repo, so cloning or forking does not grant any ability to deploy.
