Features

• 🚀 TypeScript Support: Strong type-checking for safer and more maintainable code.
• 🌟 Express.js Integration: Lightweight and robust web framework.
• 🔧 Developer Tools: Pre-configured with ESLint, Prettier, and Nodemon.
• 📂 Scalable Folder Structure: Organized for small to large applications.
• 🛡️ Error Handling: Middleware for consistent error responses.
• 📦 Dependency Management: Minimal yet extensible setup.

Requirements

Ensure you have the following installed:

• Node.js: v14 or higher
• npm or yarn: Latest version

Installation

1. Create a New Project

Using npm:

npm create express-type project-name

Or using yarn:

yarn create express-type project-name

2. Install Dependencies

Using npm:

npm install

Or using yarn:

yarn install

Project Structure

The template follows a modular and scalable folder structure:

express-ts-template/
├── eslint.config.js
├── LICENSE
├── loader.mjs
├── nodemon.json
├── package.json
├── package-lock.json
├── README.md
├── src
│   ├── controllers
│   │   └── sample.ts
│   ├── index.ts
│   ├── middlewares
│   │   └── sample.ts
│   ├── models
│   │   └── sample.ts
│   └── routes
│       └── sample.ts
└── tsconfig.json

Usage

1. Development Mode

Run the app with Nodemon for auto-reloading:

npm run dev

Access the application at: http://localhost:8000

2. Build for Production

Compile the TypeScript files to JavaScript:

npm run build

Run the compiled app:

npm start

Scripts

• npm run dev: Start the app in development mode with Nodemon.
• npm run build: Compile TypeScript to JavaScript.
• npm start: Run the compiled app in production mode.
• npm run lint: Check for linting issues.
• npm run lint:fix: Fix linting issues automatically.

Best Practices

• Type Annotations: Use TypeScript’s powerful type system to avoid runtime errors.
• Folder Organization: Keep your business logic separate from your route definitions.
• Environment Variables: Use .env files for managing secrets (e.g., database URLs).
• Error Handling: Implement consistent error responses using middleware.
• Testing: Add unit and integration tests using a framework like Jest.
