Guides

Each guide does one common job in a Jadpo app from start to finish: the code to write, the commands to run and what they print, and the reference topics that have the full rules. Every guide's code is compiled and its tests run, so each one works as shown. Read the one for the job in front of you; they don't depend on each other. To learn Jadpo from the start, follow the Learn path instead.

Build an API
You end with routes with typed input and output, the committed API record, and the OpenAPI document.
Store and change a record
You end with an entity, its migration, and actions that add, change and delete records.
Query records
You end with a query for one record, and a list a caller narrows and pages through.
Handle failures
You end with a failure of your own, refused with the right status, handled where a caller wants to.
Add sign-in
You end with sign-in by emailed link and with Google, and routes that know who is calling.
Call an outside API
You end with a typed description of another service, called through a connection and faked in tests.
Run background work
You end with a schedule that starts a batch, an event with its subscriber, and a test of the whole run.
Write tests
You end with action and route tests, fixtures, a fixed clock and tests signed in as someone.
Get a person's sign-off
You end with an acceptance for a change that could break someone, with a person's reason.
Deploy natively
You end with the app built into one program, running against a real database.
Deploy to Cloudflare Workers
You end with the app built as a Worker, reaching its database through Hyperdrive.
