#### Create MERN App

Create MERN App provides a simple file and folder structure that you can easily customize to fit your project requirements.

#### Node Version Support

| Version | Supported |
| ------- | --------- |
| node >= 18 | ✅ Yes |
| node < 18 | ❌ No |

#### 📥 Download Methods

You can download the code in two ways:

1. **Using CLI**
2. **Directly Download Zip Code**

#### 1️⃣ Using CLI

Quickly set up a new project using the \`npx\` command. Choose from different templates like app boilerplates, libraries, npm packages, or code snippets. This method ensures that you get a pre-configured structure without manual setup.

- **Pre-configured Project Creation Template:**
  \`\`\`bash
  npx create-mernjs-app my-app
  \`\`\`

- **Pre-configured Library Creation Template:**
  \`\`\`bash
  npx create-mernjs-app my-library --template library
  \`\`\`

- **Pre-built NPM Packages:**
  \`\`\`bash
  npx create-mernjs-app my-package --template packages
  \`\`\`

- **Reusable Code Snippets:**
  \`\`\`bash
  npx create-mernjs-app my-snippets --template snippets
  \`\`\`

#### 2️⃣ Directly Download Zip Code

Download the pre-built templates as a .zip file and extract them to start working on your project. This is useful if you prefer manual setup without using CLI tools.
