neon 77a80eec29 fix(server): let upload sessions recover and refuse bad input early
Five defects in resumable uploads, found while planning the Android
client's transfers:

- A create under a key whose session had failed, been cancelled or
  expired handed that dead session back, and the unique index refused a
  new one, so a client that keeps its key across Try again could never
  succeed. A dead session now releases its key, keeping its row and
  outcome, and a new session is made under it.
- A failed import was stored as UPLOAD_IMPORT_FAILED whatever the error,
  with the raw exception message, which can carry server paths. A coded
  upload error now keeps its own code and message; anything else is
  stored with a fixed message and the raw error goes to the log.
- Upload capabilities listed every reachable library whatever its type,
  and the session routes had no type check. Only book libraries are
  offered or accepted, as on the older library upload route.
- Contents that do not match the format were refused only at complete,
  after every byte was sent, and the session stayed receiving. The first
  chunk is now checked against the format's signature, and refused
  contents end the session and free its staged bytes.
- A chunk's body was read while the session's lock was held, with no
  timeout, so a connection gone half-open blocked every later chunk,
  complete and cancel for that session until the server restarted. The
  body is now read before the lock is taken, and a chunk that sends
  nothing for two minutes is given up.

The response shapes and request fields are unchanged.

BookOrbit - Server

NestJS 12 backend running on Fastify.

Running

From the repo root: pnpm dev (starts both server and client).

Server only: pnpm start:dev (from this directory).

The server loads environment variables from .env in this directory. See .env.example for all available options.

API docs

OpenAPI docs are disabled by default. Enable them with SWAGGER_ENABLED=true:

SWAGGER_ENABLED=true pnpm start:dev

Then open:

Dev watch uses a Nest config without the Swagger metadata generator so the server does not restart immediately after startup. Full build output still uses the standard Nest config and generates src/metadata.ts for enriched docs.

Module structure

Each feature is a self-contained NestJS module under src/modules/:

src/modules/
├── auth/           Authentication (JWT, OIDC, password reset)
├── book/           Book CRUD, cover images, file serving
├── library/        Library management
├── scanner/        File system scanning, metadata extraction
├── collection/     User book collections
├── smart-scope/           Saved search/filter views
├── user/           User management
├── role/           Roles and permissions (RBAC)
├── metadata/       Book metadata providers
├── kobo/           Kobo device sync
├── annotation/     Highlights and annotations
├── bookmark/       Reading position bookmarks
├── reader-preferences/  Per-user reader settings

├── path/           File path utilities
├── seed/           Database seeding
└── app-settings/   Global application settings

Database

Schema files live in src/db/schema/, one per domain. Migrations are generated by Drizzle Kit.

pnpm db:generate add_some_column   # generate migration from schema diff
pnpm db:migrate                     # apply pending migrations
pnpm db:studio                      # open Drizzle Studio (DB browser)

Testing

pnpm test           # unit tests
pnpm test:watch     # unit tests in watch mode
pnpm e2e:run        # app-smoke end-to-end test from server package
pnpm test:cov       # unit tests with coverage

For suite-based e2e runs, run from the repository root:

pnpm run e2e:list
pnpm run e2e:all
pnpm run e2e:run -- scanner-scenarios

Quality

pnpm type-check      # TypeScript checks (no emit)
pnpm lint:check      # Non-mutating lint checks
pnpm lint:fix        # Auto-fix lint issues
pnpm format:check    # Prettier check
pnpm format          # Prettier write

Key conventions

  • Constructor injection with @Inject(DB) for the Drizzle instance.
  • Config via @nestjs/config named configs (appConfig, dbConfig, authConfig, storageConfig, mailerConfig). Never read process.env directly in services.
  • DTOs use class-validator decorators. Global ValidationPipe rejects unknown fields.
  • Throw NestJS HttpException subclasses (NotFoundException, ForbiddenException, etc.) - never raw Error.
  • All user-owned data is scoped by userId. Service methods check ownership.
