12. The default backend, end to end#

@damatjs/default is a complete reference app demonstrating the whole framework: a user module (Better Auth models), file-based routes under /api (/api/posts, /api/users/:userId, /api/workflows) plus a top-level /health, cross-module links/, a user-onboarding saga workflow, Redis usage, and a Docker setup. Read it alongside this guide as a worked example — most patterns here are taken directly from it. Its README has the full route and feature list.

A good way to learn Damat: open backend/default/src/ next to these chapters and trace one feature end to end — its model, its service, its route, and (for onboarding) its workflow.
