Davvy is a Laravel + React app that combines a web admin/dashboard experience with a built-in SabreDAV CalDAV/CardDAV server.

It is designed for:

• Multi-user calendar and address-book hosting
• Share-based collaboration (read_only, editor, admin)
• Browser-based administration and operational controls
• DAV client interoperability with strict validation plus compatibility mode when needed
• Automated rotating backups (local + optional S3) with restore tooling

• Session-based web auth (/api/auth/*)
• Optional TOTP two-factor auth with backup codes
• Optional org-wide 2FA enforcement with grace period
• Localization support with per-user language preference and request-level locale negotiation
• DAV basic auth at /dav
• DAV app passwords for CalDAV/CardDAV clients when 2FA is enabled
• Roles: admin, regular
• Feature flags controlled by admins (public registration, owner sharing, contact management, review queue moderation, DAV compatibility mode)
• Admin user lifecycle controls, including typed-confirm account deletion with optional ownership transfer
• Admin backup controls for schedule, destinations, retention strategy, and ZIP restore import

• Default Personal Calendar and Contacts resources provisioned for each new user
• Owned + shared resource visibility in web dashboard
• Create, rename, mark sharable, and export resources
• Per-resource permission enforcement for web and DAV access

• Share permissions:
  • read_only: view only
  • editor: write/update, no collection delete
  • admin: full write + collection delete
• Owner-managed sharing can be globally disabled by admin
• Admin global sharing controls across all users/resources

• Managed contact UI (feature-gated)
• Contact writes synchronized to vCards in assigned address books
• CardDAV writes synchronized back into managed contacts
• Bidirectional related-name sync with inverse family mapping, pronoun-aware gendered labels, and neutral fallbacks when pronouns are not inferable
• Optional contact change moderation queue for cross-owner edits (opt-in, default off for personal deployments)
• Birthday/anniversary generated milestone calendars per address book, including combined couple anniversaries when relationships are mutually linked
• Apple compatibility mirror mode (selected sources mirrored into user's default contacts book)

• CalDAV/CardDAV endpoint: /dav
• Autodiscovery redirects:
  • /.well-known/caldav
  • /.well-known/carddav
• Sync-token incremental change tracking (added, modified, deleted)
• Strict payload validation by default (toggle compatibility mode for legacy clients)

• Docker-first runtime with preflight checks (php artisan app:preflight)
• Built-in scheduler (RUN_SCHEDULER=true) and queue worker (RUN_QUEUE_WORKER=true) support for periodic and queued jobs
• Automated backup tiers with rotating retention (daily, weekly, monthly, yearly)
• Restore snapshots via CLI (app:backup:restore) or Admin Control Center import flow
• Railway and Coolify deployment support
• PostgreSQL advisory-lock startup bootstrap for multi-replica safety

The repository compose.yml is tuned for production-style deployment (including Coolify magic variables).

For local development, prefer the DDEV flow below. If you still want local Docker Compose:

1. Provide required environment values (for example in .env):
   • APP_KEY=base64:<generated-key>
   • SERVICE_URL_APP=http://localhost:8080
   • SERVICE_USER_POSTGRES=<db-user>
   • SERVICE_PASSWORD_POSTGRES=<db-password>
2. Optionally enable bootstrap admin creation:
   • RUN_DB_SEED=true
   • DEFAULT_ADMIN_EMAIL=<admin email>
   • DEFAULT_ADMIN_PASSWORD=<strong password>
3. Start app + database:

docker compose up --build

If you need host-accessible ports locally, uncomment the ports mappings in compose.yml.

ddev start
ddev composer install
ddev npm install
cp .env.ddev.example .env
ddev artisan key:generate
ddev artisan migrate --seed

Create a local admin if needed:

ddev exec sh -lc "DEFAULT_ADMIN_EMAIL='admin@davvy.local' DEFAULT_ADMIN_PASSWORD='ChangeMe123!' php artisan db:seed --force --no-interaction"

Run assets:

ddev vite

Access 🔗:

• App: https://davvy.ddev.site
• DAV: https://davvy.ddev.site/dav

Run test suite:

ddev artisan test

Or via Docker:

docker build --target ci-test -t davvy-ci-test .
docker run --rm davvy-ci-test
