An Interactive Express.js API Generator

Features

• Interactive CLI powered by @clack/prompts
• Supports both TypeScript and JavaScript
• Database selection during project creation:
  • MongoDB (Mongoose)
  • MySQL
  • SQLite
  • PostgreSQL (JavaScript)
  • Prisma support coming soon
• Generates a clean Layered Architecture:
  • configs/
  • controllers/
  • dtos/
  • interfaces/
  • middlewares/
  • models/
  • repositories/
  • routes/
  • services/
  • utils/
• Optional automatic dependency installation

No more manually creating folders or copying boilerplate.

Installation

npm install -g @madhusha_99/exp-gen

Run it anywhere:

exp
# or
gen
# or
express-draft

Example

The CLI will ask you:

• Project Name
• TypeScript or JavaScript?
• Select Database
• Install dependencies?

…and generates everything for you. After that:

cd my-api
npm run dev

You're ready to start building.

Generated Architecture

Instead of a flat Express project, exp-gen creates a scalable layered architecture:

• Configurations
• Controllers
• DTOs
• Interfaces
• Models
• Repositories
• Services
• Routes
• Middlewares
• Utilities

Perfect for medium and large backend projects.
