GameTime/server/README.md

GameTime server

Headless Dart server for future GameTime account, sync and sharing features. This package is separate from the Flutter app at the repository root.

Local run

Install dependencies from this directory:

dart pub get

Run the server:

dart run bin/server.dart

The HTTP server binds to 0.0.0.0 and reads PORT from the environment. When PORT is not set, it listens on 8080.

PORT=9090 dart run bin/server.dart

PostgreSQL

Ticket #49 adds the initial sync-ready PostgreSQL schema and a minimal connection/migration utility.

Database environment variables:

• DATABASE_HOST: PostgreSQL host.
• DATABASE_PORT: PostgreSQL port, defaults to 5432 when omitted.
• DATABASE_NAME: database name.
• DATABASE_USER: database user.
• DATABASE_PASSWORD: database password.

Apply migrations from server/:

DATABASE_HOST=localhost \
DATABASE_PORT=5432 \
DATABASE_NAME=gametime \
DATABASE_USER=gametime \
DATABASE_PASSWORD=gametime \
dart run bin/migrate.dart

Migrations are read from server/migrations/ in alphabetical order. The v1 runner is intentionally simple; SQL files use idempotent DDL where practical.

The PostgreSQL integration test is skipped unless TEST_DATABASE_URL is set:

TEST_DATABASE_URL=postgres://gametime:gametime@localhost:5432/gametime dart test

Healthcheck:

curl http://localhost:8080/health

Expected response:

{"status":"ok"}

Authentication

Ticket #48 adds account registration, login, logout and bearer-token request authentication.

Endpoints:

• POST /auth/register with { "email": "...", "password": "...", "displayName": "..." }.
• POST /auth/login with { "email": "...", "password": "...", "deviceLabel": "..." }.
• POST /auth/logout with Authorization: Bearer <token>.

Passwords are stored with PBKDF2-HMAC-SHA256 via package:cryptography, using a per-password random salt. API tokens are opaque random values; only a SHA-256 hash of the token is stored in PostgreSQL.

Sync

Ticket #50 adds authenticated incremental sync endpoints using simple last-write-wins conflict resolution based on clientUpdatedAt.

Endpoints:

• POST /sync/push with Authorization: Bearer <token>.
• GET /sync/pull?since=<serverCursor> with Authorization: Bearer <token>.
• POST /sync/exchange with Authorization: Bearer <token>.

serverCursor is an ISO8601 UTC timestamp. For push, it is the greatest server_updated_at currently known for the authenticated user after applying the batch. For pull, it is the greatest serverUpdatedAt returned, or the server clock if no resource is returned.

POST /sync/exchange applies push first, then returns the pull payload with pushResults included so per-item validation errors remain visible to the client.

Sharing

Ticket #51 adds authenticated targeted sharing for programs and workout templates.

Endpoints:

• POST /shares with Authorization: Bearer <token>.
• GET /shares/inbox with Authorization: Bearer <token>.
• POST /shares/{id}/accept with Authorization: Bearer <token>.
• POST /shares/{id}/decline with Authorization: Bearer <token>.
• POST /shares/{id}/revoke with Authorization: Bearer <token>.

Creating a share stores a snapshot payload and creates pending recipient rows for known recipient emails. Unknown emails are reported as unresolvedEmails without failing the whole request. Accepting a share creates a new synced_resources copy owned by the recipient with a server-generated clientId; the sender's original resource is never modified. Accept returns 409 for revoked or already answered shares, while missing shares or recipients return 404.

Scope

Ticket #47 only scaffolds the Dart server, the hexagonal directory layout and the /health endpoint. Ticket #49 adds the first PostgreSQL schema. Ticket #48 adds authentication. Ticket #50 adds sync. Ticket #51 adds targeted sharing.

Upcoming tickets will fill the empty adapters and use cases:

• #52: Docker and registry packaging.
• #53: API, contract and integration tests.
