NestJS boilerplate generator — full-stack TypeScript production app from your requirements

Archiet generates your NestJS application from your requirements. Every module, controller, service, DTO, guard, and test is generated from your PRD — production-ready, with the boilerplate done.

What the generated NestJS app contains

TypeORM entities and migrations

• TypeORM entity for every entity in your PRD
• Relationship decorators: @OneToMany, @ManyToOne, @ManyToMany
• Column definitions matching your data model: types, nullability, indexes
• TypeORM migration for every entity and field change
• workspace_id / organization_id on every multi-tenant entity
• Repository pattern with workspace-scoped findAll() and findOne() methods

Authentication and authorization

• JwtAuthGuard (PassportJS + @nestjs/jwt) — protects every controller method
• @Roles() decorator + RolesGuard for role-based access
• JWT in httpOnly cookies — not in Authorization headers, not in localStorage
• Refresh token rotation
• @UseGuards(JwtAuthGuard, RolesGuard) applied at controller level — no unguarded routes

DTOs and validation

• class-validator decorators on all DTO classes
• ValidationPipe globally applied — invalid input returns 422
• Swagger decorators (@ApiProperty, @ApiResponse) on all DTOs and controllers
• Auto-generated Swagger UI at /api/docs

Error handling

• Global HttpExceptionFilter — consistent error response format
• {"error": "snake_case_code", "message": "Human readable description."}
• Correct HTTP status codes: 201 creation, 422 validation, 403 auth, 404 not found

Tests

• Jest test suite
• Unit tests for each service (mocked TypeORM repositories)
• E2E tests for each controller (using supertest and a test database)
• Auth test: login → get token → protected route → assert 200; no token → assert 401

Infrastructure

• Multi-stage Dockerfile (Node base → build → production)
• docker-compose.yml: NestJS app + PostgreSQL + Redis (when queues included)
• GitHub Actions: ESLint → tsc → jest → build → deploy

TypeScript strict mode

The generated NestJS code compiles with strict: true in tsconfig.json:

• No any types
• No implicit any
• Strict null checks
• tsc --noEmit passes clean

vs Nest CLI boilerplate and nestjs-boilerplate GitHub repos

nest new my-app gives you an application scaffold in 60 seconds. Popular GitHub NestJS boilerplates add auth, TypeORM, and a module structure. These solve the framework setup problem.

What they don't give you: your specific entities, your business logic, your API routes matched to your OpenAPI spec, your migrations, your product-specific tests. Archiet generates the product layer on top of the framework setup — and does it from your requirements document.

EU AI Act Annex IV (high-risk AI, deadline August 2026)

Building an AI system with EU market exposure? Start with the free EU AI Act risk classifier, then generate Annex IV technical documentation, risk tier assessment, and post-market monitoring plan from the same NestJS + Next.js blueprint that produces your app. Same genome → code + compliance artifacts.
