End-to-end builds. Each one starts from an empty folder and finishes with something that runs.
Reference pages tell you what an API does. These tell you how to put one
together.
Every guide follows the same shape: what we're building, prerequisites,
implementation, how it works, production considerations, next steps. Read
the "how it works" section — that is where the design decisions are, and
they are the part that transfers to your own app.
You need a project, an API key, and somewhere to run a small backend. If you
do not have those, spend five minutes on the
Quickstart first — every guide assumes it.
- Examples — the same ideas as runnable apps in the repository.
- Concepts — the vocabulary the guides use.
