⚡ Express + Mongoose + TypeScript Module Generator

🚀 Overview

exp-cli-gen is a powerful Express + TypeScript module generator that uses Mongoose for database interaction.
It automatically creates a complete module structure — including models, controllers, services, routes, Zod validations, and Swagger documentation — all in one command.

Ideal for developers who want to quickly scaffold modular Express APIs with clean architecture and ready-to-use integrations.

✨ Features

• ⚙️ Generates full-featured Express + TypeScript modules
• 🧩 Automatically integrates Mongoose models and Zod validations
• 📘 Adds Swagger documentation automatically
• 🚀 Clones and sets up a ready-to-run Express starter project
• 🔁 Can add new modules anytime with a single command
• 🧠 Skips redundant setup if the starter pack already exists
• 💪 Built for scalability and maintainability

📦 Installation

Install globally:

npm install -g exp-cli-gen

Or run directly using npx (recommended):

npx exp-cli-gen <module-name>

Usage

🏗️ Generate your first module

Run:

npx exp-cli-gen test

First run example:

Need to install the following packages:
[email protected]
Ok to proceed? (y)

⠋ No Express project found. Cloning starter pack...
✔ Starter project cloned!

✔ Git logs removed!

📦 Installing dependencies...

🚀 Project setup complete.
🧩 Generating module: test...
✔ test.interface.ts created
✔ test.schema.ts created
✔ test.validation.ts created
✔ test.route.ts created
✔ test.controller.ts created
✔ test.service.ts created
✔ test.swagger.ts created

🔗 Route added to src/app/routes.ts
📘 Swagger doc added to src/swaggerOptions.ts
✨ Module 'test' created successfully!

📁 Generated Module Structure

Each generated module will contain the following files:

src/app/modules/<module-name>/
 ├── <module-name>.interface.ts
 ├── <module-name>.schema.ts
 ├── <module-name>.validation.ts
 ├── <module-name>.route.ts
 ├── <module-name>.controller.ts
 ├── <module-name>.service.ts
 └── <module-name>.swagger.ts

🔄 Add More Modules

Need another module? Just run:

npx exp-cli-gen products

If the starter project already exists, it will skip cloning and directly add the new module.

Example output:

ℹ 📦 Starter folder already exists. Skipping clone.
📦 Dependencies already installed. Skipping npm install.
🧩 Generating module: products...
✔ products files created
✨ Module 'products' created successfully!

src/app/modules/products/
 ├── products.interface.ts
 ├── products.schema.ts
 ├── products.validation.ts
 ├── products.route.ts
 ├── products.controller.ts
 ├── products.service.ts
 └── products.swagger.ts

Then, refresh your Swagger docs at:

http://localhost:5000/docs

You’ll see your new routes automatically added.

⚙️ Configuration

After setup, update your .env file following the .env.example file in the starter project.

To start the server:

npm run dev

Open Swagger documentation at:

http://localhost:5000/docs
