application/problem+json responses. - Persistence & Security Basics: Provides Prisma schema, migration, transaction, and pagination patterns plus bcrypt/argon2 password hashing, secret externalization via ConfigModule, and Jest testing conventions. - Use Case: When asked to build a signup API in a NestJS project, the Skill produces a feature module with a thin controller, validated DTOs, a service that hashes passwords before storage, Prisma persistence, and consistent error responses. ## Quick Start Use the nestjs skill to implement a new REST endpoint with its module, controller, service, DTOs, and Prisma persistence in this project.High-intent search queries and answers about installing and using this skill.
Encapsulate each feature in its own module with a thin controller handling routing and validation, and an @Injectable service containing business logic. Dependencies flow unidirectionally from controller to service to Prisma, using constructor injection throughout.
Define DTO classes with class-validator decorators like @IsString and @IsInt, then register a global ValidationPipe with whitelist and transform enabled in main.ts. This strips unknown fields, converts types, and returns 400 errors automatically.
Yes, by implementing a global exception filter that catches HttpException instances and maps them to application/problem+json bodies with type, title, status, detail, and instance fields. Validation failures can include field-level errors in an extensions array.
Wrap bcrypt or @node-rs/argon2 in an injectable PasswordHasher provider and call its hash method in the service before persisting. Never store plaintext passwords, and exclude hash fields from response DTOs and Prisma select queries.
The recipes center on Prisma with PrismaService, schema.prisma, migrations, and $transaction patterns. For TypeORM or Mikro-ORM projects, the same principles of persistence boundaries and repository abstraction apply using that tool's idioms.
Mocked Prisma clients cannot verify real queries or constraints. Use a separate test database via a .env.test DATABASE_URL, or spin up an isolated Postgres with Testcontainers and apply migrations before running supertest e2e tests.
