Recipes

Connect Brevity to the tools you already use. Each recipe includes runnable source; start with the notebook tutorial if you're new here.

Data

• Drizzle + SQLite: a small repository with transactions.
• Prisma: use the same app with a generated database client.

Pages and sign-in

• Supabase sign-in: passwordless email with server-side sessions.
• Svelte island: add a counter without replacing a native form.

Routes and tests

• Controller decorators: group routes into classes.
• Domain errors: translate expected failures into HTTP responses.
• HEAD routes: serve headers without a response body.
• HTTP tests: test against a real listener on a free port.
• Playwright: check the browser with JavaScript on and off.
• Health and shutdown: drain requests before closing resources.

Versions and checks

Tool versions and automated coverage

These recipes use Drizzle 0.45.4, libSQL client 0.15.15, Prisma 6.12.0, Supabase SSR 0.7.0 / JS 2.57.4, cookie 1.0.2, Svelte 5.57.2, Vite 6.4.4, Svelte Vite plugin 5.1.1, and Playwright 1.56.0. CI checks Node 20/22/24; browser checks run on Node 22. Newer versions need their own compatibility checks.

Listings come from docs/samples/. npm run docs:check typechecks them, generates Prisma's client, builds Svelte, and runs HTTP tests. npm run docs:e2e adds Chromium checks. The Supabase recipe's automated tests stub Auth HTTP; email delivery and hosted refresh need a configured environment.
