Model MVC Generator for Express

A simple CLI tool for generating a basic MVC module structure for Node.js and Express applications.

This tool automates the creation of common backend layers such as controllers, services, models, and routes. It helps developers quickly scaffold a modular structure following a layered MVC-style architecture.

Features

• Generates a basic module structure
• Creates controllers, services, models, and routes directories
• Automatically creates starter files for each layer
• Uses a simple CLI command
• Designed for Express-style backend projects

Installation

Install globally using npm:

    npm install -g model-mvc

Or run directly with npx:

    npx model-mvc <module-name>

Usage

Generate a new module by running:

    npx model-mvc user

This will create the following structure:

src/ user/ controllers/ userController.js services/ userService.js models/ userModel.js routes/ userRoute.js

Each module is grouped by feature, which improves organization and scalability in larger backend applications.

Architecture

The generated structure follows a layered MVC-style architecture with an additional service layer.

Flow:

Route → Controller → Service → Model → Database

Layer responsibilities:

Controller Handles HTTP requests and responses.

Service Contains business logic and application rules.

Model Responsible for data access and persistence.

Routes Defines API endpoints and connects them to controllers.

Requirements

Node.js 16 or higher npm

Development

Clone the repository:

    git clone https://github.com/tulio-ferreira21/model-mvc-generator

Install dependencies if needed and link the CLI locally:

    npm link

Now the command will be available globally on your system.
