Workers foundations
Create the Link Vault project
Scaffold a TypeScript Worker with the current Cloudflare project generator and inspect the generated configuration and scripts.
8 minute lesson
The course project is Link Vault, a small service that saves useful links, serves a web interface, and exports backups.
Use Cloudflare’s current project generator and select a Worker starter. The generator records current tool versions and a compatibility date, so prefer its output to hand-copying an old configuration example.
npm create cloudflare@latest -- link-vault
cd link-vault
npm run devThe generated project is also a record of assumptions: package versions, module format, compatibility date, entry point, and local test setup. Commit those files together so another developer can reproduce the same baseline. Do not copy a compatibility date from an old tutorial; it controls runtime behavior and should be advanced intentionally with tests.
Before changing application code, run the generated test and a dry deployment. If either fails, fix the baseline first. Record the local URL, send one request with curl, and inspect the response headers so later routing or binding failures have a known-good comparison.
Open the local URL and identify src/index.ts, wrangler.jsonc, generated types, and test configuration.
