🚀 TypeScript-Express Backend Setup CLI

A CLI tool to quickly setup an Express.js backend in TypeScript, using essential configurations and user's preferences.

⚡ Installation

You can directly run the CLI (using npx) or install globally (using npm install -g) :

# Run directly using npx
npx create-types-backend@latest

# OR Install globally (optional)
npm install -g create-types-backend

📦 Features

✅ Generates a well-structured Express-TypeScript backend
✅ Supports automatic setup using -y flag
✅ Includes Express.js, Typescript, DotEnv and essential configurations
✅ Sets up tsx for hot-reloading while development
✅ Resolves default import alias by mapping src -> @

⚙️ Optional support for:

- Custom Error Handler + Try-Catch Wrapper
- CORS
- MongoDB (with Mongoose)
- JWT, bcrypt, cookie-parser
- Multer
- Cloudinary
- ES-Lint
- Prettier
- Docker (with separate Development and Production configurations)
- Git

🚀 Usage

➡️ Creating a new project

npx create-types-backend  : Manual setup with flexibility to choose required configurations.

OR

npx create-types-backend  -y : Run in default mode with all preferences set to 'DEFAULT' values.

OR

npx create-types-backend  myapp : Enter project name through CLI argument

➡️ Starting the Development Server

Just follow these 3 steps:

-   cd into the newly created backend directory
-   add your MONGODB_URI in .env file (if using MongoDB)
-   npm run dev OR npm run docker:dev (if using docker)
