# hemx SaaS tutorial app

This is the compile-tested v1 production-shaped tutorial app. It intentionally uses an equivalent local persistence adapter and provider recipes as the supported v1 production boundary: auth/session, CSRF, SQLx persistence, deploy, metrics, flags, offline behavior, and islands are explicit app integrations, not hemx core services. Read the walkthrough in `../../docs/tutorial-saas.md`. req: examples/001 req: auth/001

What it proves:

- typed form/newtype inputs for project creation
- auth/session context passed through normal Rust state
- CSRF-safe mutation checked before persistence
- local atomic-file persistence adapter with rollback and process-restart proof instead of a vendored SQL/auth provider
- a bounded `POST /projects` reference boundary requiring the current bearer session, exact origin, CSRF token, and matching generated build fingerprint when supplied
- `/health/live`, dependency-aware `/health/ready`, and aggregate `/metrics` endpoints with secret-free structured diagnostics
- generated form, slot, keyed row, page-swap, and live-status commands
- page shell with plain CSS and one explicit metrics island script
- compile-time surface generation plus interaction tests

For provider-explicit boundaries, see `../../docs/recipes/sqlx-persistence.md`, `../../docs/recipes/auth-session-csrf.md`, `../../docs/recipes/observability-flags.md`, `../../docs/recipes/deploy-versioning.md`, and `../../docs/recipes/pwa-offline.md`.

What it deliberately keeps out of the tutorial crate:

- a vendored SQL/auth/metrics/flags/deploy provider dependency
- provider credentials, external services, migrations, or browser automation
- billing, account administration, or other SaaS platform scope

Database encryption, backups, retention, incident policy, and identity-provider compliance remain host responsibilities; hemx does not claim them as framework controls. Those production concerns belong in app adapters and recipes so the tutorial remains runnable in CI without external side effects. req: security/009
