🚀 I Built `exp-gen` — An Interactive Express.js API Generator

After spending a lot of time creating the same Express.js project structure over and over again, I decided to automate the entire process.

Introducing exp-gen 🎉

A fast, interactive CLI that scaffolds production-ready Express.js APIs in seconds.

✅ Interactive CLI powered by @clack/prompts

✅ Supports both TypeScript and JavaScript

✅ Database selection during project creation

✅ Generates a clean Layered Architecture

✅ Optional automatic dependency installation

No more manually creating folders or copying boilerplate.

npm install -g @madhusha_99/exp-gen

Run it anywhere:

exp

# or

gen

# or

express-draft

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.

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

Perfect for medium and large backend projects.

I'd love to grow this into a community project.
