# 🚀 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**) :

```sh
# Run directly using npx
npx create-types-backend

# 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 Handlers
    - CORS
    - MongoDB
    - JWT, bcrypt, cookie-parser
    - Multer
    - Cloudinary
    - ES-Lint
    - Docker

## 🚀 Usage

➡️ Creating a new project

```sh
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 'YES'

OR

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

➡️ Starting the Development Server

```sh
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)
```
