Cloudflare Pages hands-on tutorial: from zero to your first runnable project
Step-by-step walkthrough of Cloudflare Pages with copy-paste commands, directory layout, and a first runnable artifact.

Quick answer
How do I pin Cloudflare Pages and Workers runtime versions?
Use compatibility_date in wrangler.toml to lock the runtime behavior. Validate any bump on a Preview branch first so breaking changes never reach production.

In-depth analysis
Cloudflare Pages watches your Git branch, builds on every commit, and atomically publishes the result to the global edge — zero-ops static hosting. Going from zero to a first runnable project is about locking in the smallest end-to-end loop before you scale.

FAQ & pitfalls
Why are _headers and _redirects not taking effect?
Both files must live in the output root (e.g. dist/). Placing them under src/ means they never ship. Pure static projects should not force a _worker.js either, or you lose the zero-cold-start advantage.

Questions that keep coming back in reader feedback, already answered.
- 01
Why are _headers / _redirects not taking effect?
Both files must sit at the root of the output directory (dist/); anything under src/ is never uploaded. A purely static project should not add _worker.js either — that gives up the zero-cold-start advantage.

How do I invalidate the Cloudflare edge cache precisely?
Give static assets a long immutable max-age and serve HTML with must-revalidate. Changing a filename changes the URL, so Cloudflare fetches the new version automatically.

Why is my Astro component's interactivity not working?
Components ship as zero-JS HTML by default, so an interactive one needs a client:* directive (client:load, client:visible, …). Without it the script is never bundled into the page.
