Examples

Every example is a complete Django project with its own tests. CI runs them all (pytest, mypy --strict, makemigrations --check, manage.py check, devx_scaffold --check).

Example	What it shows	Size
quickstart	a private notes API: CRUD, ownership, search, filters, a custom action	1 app
blog	the tutorial: scaffolding, soft delete, nested comments, idempotency, versioned mount, generated TypeScript and Python clients	1 app
recipes	one order API written three ways (HackSoft services, Cosmic-lite use cases and repositories, dishka interactors) passing the same contract tests	4 apps
saas	a multi-tenant issue tracker: tenant_field, roles, archiving, ETag/If-Match, cursor pagination, throttles, field visibility, problem+json, schemathesis	1 app
async_api	async-first orders: one hop per write, async dependencies with cleanup, run_atomic, server-sent events, async hooks	1 app

Run one

git clone https://github.com/ctolon/ninja-devx && cd ninja-devx
uv sync --locked --group docs --group verification
cd examples/saas
uv run --project ../.. pytest -q
uv run --project ../.. python manage.py migrate
uv run --project ../.. python manage.py runserver   # http://127.0.0.1:8000/api/docs

Session-based examples include /accounts/login/ and a local login template. Run createsuperuser and sign in before using their docs UI. The SaaS example uses a deliberately insecure username bearer token; follow its README to create a workspace/member and send both required headers. Each README names its deployment boundaries. These projects are executable library demonstrations, not production templates.

Which example for which question

Question	Look at
How little code does a CRUD API need?	quickstart/notes/api.py
How do I isolate tenants and roles?	saas/tracker/tenancy.py, saas/tracker/api.py
Where does business logic go?	recipes/ (three answers), saas/tracker/api.py (IssueService)
How do I keep async code fast?	async_api/orders/api.py and its hop assertions
How do I generate clients and keep them current?	blog/clients/, blog/blog/tests/test_api.py
How do I fuzz my API from its schema?	saas/tracker/tests/test_contract.py
