SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Quickly generating runnable Node.js (Express) backends with Swagger/OpenAPI documentation, while enforcing contract-driven boundaries to prevent scope creep and architecture drift.

Core Features & Use Cases

  • Generates a clean, testable Express API scaffold with comprehensive OpenAPI specifications
  • Supports both in-memory storage and PostgreSQL, chosen by the user prompt
  • Includes migration-ready guidance and configuration contracts to ensure safe, scalable backends

Quick Start

Provide your API requirements in a prompt and run the generator to scaffold a Node.js backend.

FAQPage Schema
How do I generate a Node.js Express backend from an OpenAPI contract?

You can generate a Node.js Express backend from an OpenAPI contract by providing your API requirements in a prompt. The generator scaffolds a runnable backend using Swagger as the single source of truth for contract-driven architecture.

What is Swagger-first development for Node.js APIs?

Swagger-first development for Node.js APIs means using OpenAPI specifications as the single source of truth. This approach enforces contract-driven boundaries to prevent scope creep and architecture drift when generating Express backends.

Can I use PostgreSQL for storage when scaffolding an Express API?

Yes, you can use PostgreSQL for storage when scaffolding an Express API. The generator supports both PostgreSQL and in-memory storage options, chosen based on your prompt, and includes migration-ready guidance for safe database usage.

How do I scaffold a production-grade Express API with database migrations?

To scaffold a production-grade Express API with database migrations, provide your complexity and storage requirements in a prompt. The generator enforces explicit configuration, safe database usage, and migration-ready guidance for scalable backends.

Does contract-driven API generation prevent architecture drift in Node.js?

Contract-driven API generation prevents architecture drift in Node.js by using Swagger as the single source of truth. This enforces strict contract boundaries, ensuring your Express backend scaffold remains testable and aligned with your OpenAPI specifications.

What do I need to provide to scaffold a Swagger-first Node.js backend?

To scaffold a Swagger-first Node.js backend, you need to provide your API requirements, storage choices, and complexity level in a prompt. The generator then applies contract-driven architecture to produce a clean, testable Express API scaffold.
