## ⚡ Quick Demo

```bash
# Install globally
npm install -g kickstart-express

# Create a new project (default behavior)
kickstart-express --name my-api --language ts --docker --src --structured

# Add features to existing projects
kickstart-express add database

# Navigate and start
cd my-api && pnpm dev
```

Your Express server will be running at `http://localhost:3000` with a fully configured TypeScript setup, Docker containers, and organized project structure!

## 🚀 Features

- **Simplified CLI** - No more "create" command needed - scaffolding is the default behavior
- **Feature Addition** - Use `add` command to extend existing projects with databases, auth, and more
- **Interactive & Non-Interactive CLI** - Use prompts or pass arguments for instant scaffolding
- **Graceful Interruption Handling** - Safe Ctrl+C handling with automatic cleanup of partial projects
- **TypeScript & JavaScript Support** - Choose your preferred language
- **Flexible Project Structure** - From simple to enterprise-ready architectures
- **Docker Ready** - Optional Docker configuration included
- **Modern Tooling** - Pre-configured with ESLint, hot reloading, and build scripts
- **Best Practices** - CORS, environment variables, and structured routing

## 📦 Installation

### Global Installation (Recommended)
```bash
npm install -g kickstart-express
```

### Using npx (No Installation Required)
```bash
npx kickstart-express
```

## 🛠️ Usage

### Creating New Projects

#### Interactive Mode (Default)
Simply run the command and follow the interactive prompts to create a new Express.js project:

```bash
kickstart-express
```

The CLI will ask you:
1. **Project name** - Name for your new project directory
2. **Language** - Choose between TypeScript or JavaScript
3. **Include Dockerfile** - Optional Docker configuration
4. **Source folder structure** - Simple or organized structure
5. **Structured architecture** - Controllers, services, and routes separation

#### Non-Interactive Mode (CLI Arguments)
You can also pass arguments to skip prompts and scaffold projects instantly:

```bash
kickstart-express --name my-api --language ts --docker --src --structured
```

#### Available CLI Options for Project Creation:
- `-n, --name <project-name>` - Specify the project name
- `-l, --language <ts|js>` - Choose language (default: ts)
- `-d, --docker` - Include Dockerfile and docker-compose.yml
- `-s, --src` - Create src folder structure
- `--structured` - Use structured architecture (controllers, services, routes)
- `-h, --help` - Display help information
- `-V, --version` - Display version number

### Adding Features to Existing Projects

Kickstart Express v2 introduces the `add` command to extend your existing projects with both interactive and non-interactive modes:

```bash
kickstart-express add <feature> [options]
```

#### Available Features:
- `database` or `db` - Add database support (MongoDB/PostgreSQL with Mongoose/Prisma/Drizzle)
- `auth` - Add authentication support (JWT or Clerk)

#### Interactive Mode (Default)
When run without CLI options, prompts guide you through feature configuration:

```bash
# Interactive database setup
kickstart-express add db

# Interactive authentication setup
kickstart-express add auth
```

#### Non-Interactive Mode (CLI Arguments)
Skip prompts by providing configuration options directly:

**Database CLI Options:**
- `--db-type <mongodb|postgres>` - Database type selection
- `--orm <mongoose|prisma|drizzle>` - ORM/ODM selection

**Authentication CLI Options:**
- `--auth-type <jwt|clerk>` - Authentication type selection

#### Examples:

**Interactive Mode:**
```bash
# Add database support (interactive prompts)
kickstart-express add database

# Add authentication (interactive prompts)
kickstart-express add auth
```

**Non-Interactive Mode:**
```bash
# Add MongoDB with Mongoose
kickstart-express add db --db-type mongodb --orm mongoose

# Add PostgreSQL with Prisma
kickstart-express add db --db-type postgres --orm prisma

# Add PostgreSQL with Drizzle
kickstart-express add db --db-type postgres --orm drizzle

# Add JWT authentication
kickstart-express add auth --auth-type jwt

# Add Clerk authentication
kickstart-express add auth --auth-type clerk
```

**Fallback Behavior:**
When run outside a kickstart-express project, the add command will prompt to create a new project instead.

### Examples

#### Create Projects:

**TypeScript project with all features:**
```bash
kickstart-express -n my-awesome-api -l ts -d -s --structured
```

**Simple JavaScript project:**
```bash
kickstart-express --name simple-app --language js
```

**Partial arguments (will prompt for missing options):**
```bash
kickstart-express --name my-app --docker
```

**Quick TypeScript project with src folder:**
```bash
kickstart-express -n quick-api -s
```

#### Add Features:

**Interactive Mode:**
```bash
# Add database support with prompts
cd my-existing-project
kickstart-express add database

# Add authentication with prompts
kickstart-express add auth
```

**Non-Interactive Mode:**
```bash
cd my-existing-project

# Add MongoDB with Mongoose
kickstart-express add db --db-type mongodb --orm mongoose

# Add PostgreSQL with Prisma
kickstart-express add db --db-type postgres --orm prisma

# Add JWT authentication
kickstart-express add auth --auth-type jwt
```

**Complete Workflow:**
```bash
# 1. Create project
kickstart-express -n my-api -l ts -d -s --structured

# 2. Add database support
cd my-api
kickstart-express add db --db-type postgres --orm prisma

# 3. Add authentication
kickstart-express add auth --auth-type jwt
```
