Three book request defects, found while planning the Android client: - The sweep that cancels a self-serve request nobody picked a release for timed it from createdAt. A self-fulfiller who took on an older request somebody else made inherited that clock, so a request taken on more than six hours after it was made was cancelled at the next sweep and dismissed for the person who asked for it. It is now timed from when the request became self-serve, the decidedAt that creating it self-serve and taking it on both set. - The grab routes kept Fastify's 1 MiB body limit while their DTO takes a base64 .torrent of up to 4 Mi characters and the service 2 MiB decoded, so a .torrent over about 768 KiB was refused with a 413 before the DTO was read. Both grab routes now declare a body limit that fits the DTO. - Approving with a new library and no folder kept the request's stored folder, which belongs to its old library, and was refused with SUBMIT_FOLDER_NOT_IN_LIBRARY; nothing the approver could send cleared it. Rerouting without a folder now leaves the old one behind.
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:
- Swagger UI: http://localhost:6262/api/docs
- OpenAPI JSON: http://localhost:6262/api/docs-json
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

├── cbz/ CBZ archive handling
├── 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/confignamed configs (appConfig,dbConfig,authConfig,storageConfig,mailerConfig). Never readprocess.envdirectly in services. - DTOs use
class-validatordecorators. GlobalValidationPiperejects unknown fields. - Throw NestJS
HttpExceptionsubclasses (NotFoundException,ForbiddenException, etc.) - never rawError. - All user-owned data is scoped by
userId. Service methods check ownership.
