Examples

Short patterns live in Recipes - pick a scenario and copy the full snippets.

The guides explain each feature in depth. For copy-paste, end-to-end setups, use the Recipes section:

REST API + typed client - CRUD, AppRouter, import.meta.main
Auth with JsonToken - public login before .use(), then protected routes
CORS for a SPA - origin whitelist, credentials, custom headers
File uploads - multipart, z.file(), save to disk
Errors & notFound - validation 400, onError, HttpClientError
Behind a reverse proxy - trustProxy, req.ip
Testing without a port - server.fetch
