SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prototype-builder scaffolds runnable prototype projects.

Core Features & Use Cases

  • Template-based scaffolding for Full-stack Web (Next.js + FastAPI), API Services, and CLI Tools.
  • Dynamic project generation when no template is chosen.
  • Automatic Makefile setup with a start target and essential scaffolds (entry points, dependencies, and README).

Quick Start

Provide a project name and type to initiate scaffolding, choose a stack (or use defaults), and run the generation. The tool will create the project under ~/projects/<project-name>/ with a Makefile, skeleton code, and documentation.

FAQPage Schema
How do I scaffold a Next.js and FastAPI prototype project?

To scaffold a Next.js and FastAPI prototype, provide a project name and type to initiate generation. The tool creates a project skeleton under ~/projects/<project-name>/ with a working Makefile, enabling immediate startup.

Can I generate a CLI tool skeleton with a working Makefile?

Yes, you can generate a CLI tool skeleton with a working Makefile. Select the CLI tool template during generation, and the tool will output essential scaffolds including entry points, dependencies, and a Makefile with a start target.

What is the best way to bootstrap a runnable API service quickly?

The best way to bootstrap a runnable API service quickly is using a template-based scaffolding tool. It copies templates, updates README and config files, and ensures 'make start' runs to boot the project immediately.

Does the project generator work if I don't choose a specific template?

Yes, the project generator works if you don't choose a specific template. It supports dynamic project generation by using default stack settings to create the skeleton, config files, and Makefile.

Where are my newly generated prototype projects saved?

Newly generated prototype projects are saved in a default location at ~/projects/<project-name>/. The generator copies template assets to this directory and wires the Makefile for immediate execution.
