## ⚡ Requirements

Before you begin, ensure your system meets these requirements:

- **Node.js**: Version 14.x or higher
- **npm**: Version 6.x or higher
- **MongoDB**: Local or remote installation

## 📦 Installation

Install the CLI tool globally to use it from anywhere in your system:

```bash
npm install -g mern-project-cli
```

To check installation version:

```bash
devcli --version
```

## 🛠️ Commands

### 1. Create MERN Project

```bash
devcli create
```

#### What This Command Does:

##### 1. **📁 Creates Project Structure**:

The generated project follows the MVC (Model-View-Controller) pattern, a battle-tested architecture that separates your application into three main components:

```
your-project-name/
├── backend/
│ ├── controllers/ # Handle business logicdocumentation
│ ├── db/ # Database configuration
│ ├── middlewares/ # Custom middleware functionsdocumentation
│ ├── models/ # MongoDB Schema model
│ ├── routes/ # API route definitions
│ ├── utils/ # Helper functionsdocumentation
│ ├── .env.example # Environment variables template
│ ├── .gitignore # Git ignore rules
│ ├── constants.js # Application constants
│ ├── package.json # Dependencies and scripts
│ ├── README.md # Backend documentation
│ └── server.js # Server entry point
└── frontend/
├── public/ # Static files
├── src/ # React source code
│ ├── components/ # React components
│ ├── pages/ # Page components
│ ├── utils/ # Helper functions
│ └── App.js # Root component
├── .env.example # Frontend environment template
└── package.json # Frontend dependencies
```

##### 2. **Installs Dependencies**:

- Backend: Express, Mongoose, CORS, dotenv, nodemon.
- Frontend: React, React Router, Axios, Other Create React App dependencies.

#### After Creation:

##### **Start Backend Development**:

```bash
cd your-project-name/backend
```

```bash
npm run dev # Start development server with nodemon
```

##### **Start Frontend Development**:

```bash
cd your-project-name/frontend
```

```
npm start # Start React App
```

Option:

```bash
devcli create my_project --next
```

### 2. Connect MongoDB

- Create database as your_project_name_db

```bash
devcli mongodb-connect
```

- Or with custom database name

```
devcli mongodb-connect --project custom-name
```

#### Options:

- `-p, --project `: Specify custom database name
- No options: Uses project folder name as database name

#### What This Command Does:

##### 1. **Creates Database Connection**:

- Generates `connection.js` in the `db` folder
- Sets up Mongoose connection with error handling
- Configures connection string based on environment variables

##### 2. **Updates Server Configuration**:

- Adds database connection import to `server.js`
- Sets up connection status logging

#### Usage Examples:

```bash
# Using project name
devcli mongodb-connect

# Using custom database name
devcli mongodb-connect --project custom_name
```

#### Generated Files:

```javascript
// db/connection.js
require('dotenv').config();
const mongoose = require('mongoose');

const dburl = process.env.DB_URL || 'mongodb://localhost:27017/your_db_name';
mongoose
.connect(dburl)
.then(() => console.log('Connected to DB Successfully'))
.catch((err) => console.log(err.message));
```

### 3. Generate Mongoose Schema

- Create mongoose schema for your backend.

```bash
devcli devcli mongoose-schema

```

#### Usage Example

```bash
devcli mongoose-schema User name:String email:String password:String
```

This will create a `User.js` file with a Mongoose schema inside the `models/` directory:

```javascript
//models/User.js
import mongoose from 'mongoose';

const UserSchema = new mongoose.Schema({
name: { type: String, required: true },
email: { type: String, required: true },
password: { type: String, required: true },
});

const User = mongoose.model('User', UserSchema);
export default User;
```

#### Explanation:

The `mongoose-schema` command takes a model name (User) and field definitions (name:String, email:String, password:String), generating a Mongoose model file in the `models/` folder.

### 4. Add Redux

Set up Redux in your project or add new Redux slices.

#### Initialize Redux

```bash
devcli add-redux --init
```

###### What does this command do:

- Sets up Redux store configuration
- Creates necessary store files and directories
- Installs required dependencies (@reduxjs/toolkit and react-redux)
- Creates hooks for easier Redux usage

#### Create Redux Slice

```bash
devcli add-redux --slice --actions="action1,action2" --state="field1:type,field2:type"
```

Options:

- `--slice`: Name of the slice to create
- `--actions`: Comma-separated list of actions for the slice
- `--state`: Initial state fields with types (string, boolean, array)

#### Usage Example:

```bash
devcli add-redux --slice user --actions="login,logout" --state="username:string,isLoggedIn:boolean"
```

This creates:

- A new slice file in `src/store/slices`
- Boilerplate for specified actions
- Initial state with typed fields
- Automatic integration with the Redux store

#### Example Generated Redux Slice

When you run the command:

```bash
devcli add-redux --slice user --actions="login,logout" --state="username:string,isLoggedIn:boolean"
```

It generates the following slice in `src/store/slices/userSlice.js`:

```javascript
import { createSlice } from '@reduxjs/toolkit';

const initialState = {
username: '',
isLoggedIn: false,
};

const userSlice = createSlice({
name: 'user',
initialState,
reducers: {
login: (state, action) => {
// Implement login logic here
},
logout: (state, action) => {
// Implement logout logic here
},
},
});

export const { login, logout } = userSlice.actions;
export default userSlice.reducer;
```

### 5. Create Frontend Project

Create a new React project with either Shadcn UI + Tailwind CSS or just Vite + Tailwind CSS using a single command.

```bash
# Create project with Shadcn UI
devcli create-frontend --shadcn

# Create project with Vite + Tailwind CSS
devcli create-frontend --vite
```

#### Features

##### With --shadcn flag:

- Creates a Vite + React project
- Installs and configures Tailwind CSS
- Sets up Shadcn UI with New York style and Zinc color scheme
- Configures project structure with best practices
- Adds initial button component as example
- Sets up path aliases for better imports
- Includes all necessary configuration files

##### With --vite flag:

- Creates a basic Vite + React project
- Installs and configures Tailwind CSS
- Sets up minimal project structure
- Includes starter template with modern styling

#### Options

- `--shadcn`: Include Shadcn UI setup with Tailwind CSS
- `--vite`: Create basic Vite project with Tailwind CSS only

#### Usage Examples

```bash
# Create a new React project with Shadcn UI
devcli create-frontend my-app --shadcn

# Create a new React project with just Vite + Tailwind
devcli create-frontend my-app --vite

# Navigate to project
cd my-app

# Start development server
npm run dev
```

#### Generated Project Structure with --shadcn

```
your-project/
├── src/
│ ├── components/
│ │ └── ui/
│ │ └── button.jsx
│ ├── lib/
│ │ └── utils.js
│ ├── App.jsx
│ └── index.css
├── jsconfig.json
├── tailwind.config.js
├── vite.config.js
└── components.json
```

#### After Creation with --shadcn

- Add more Shadcn components using:
```bash
npx shadcn@latest add
```
- Available components can be found at [shadcn/ui components](https://ui.shadcn.com/docs/components)
- Customize theme in `tailwind.config.js`
- Add your own components in `src/components`

### 6. Initialize Docker Files

Generate Dockerfiles for both backend and frontend, along with a docker-compose.yml file for your MERN stack project.

```bash
devcli init-dockerfiles
```

#### What This Command Does:

1. **Creates Backend Dockerfile**:

- Uses Node.js 20 Alpine image
- Sets up working directory
- Installs dependencies
- Configures for development mode
- Exposes port 5000

2. **Creates Frontend Dockerfile**:

- Uses Node.js 20 Alpine image
- Sets up working directory
- Installs dependencies
- Exposes port 3000
- Configures for development mode

3. **Generates docker-compose.yml**:
- Configures services for backend, frontend, and MongoDB
- Sets up proper networking between services
- Configures volumes for development
- Sets environment variables
- Establishes service dependencies

#### Requirements:

- Project must have `backend` and `frontend` directories in root
- Docker must be installed on your system

#### Generated Files:

```
your-project/
├── backend/
│ ├── Dockerfile
│ └── .dockerignore
├── frontend/
│ ├── Dockerfile
│ └── .dockerignore
└── docker-compose.yml
```

#### Usage:

```bash
# Navigate to your project root
cd your-project

# Generate Docker files
devcli init-dockerfiles

# Start the containerized application
docker-compose up
```

This will start your application with:

- Backend running on `http://localhost:5000`
- Frontend running on `http://localhost:3000`
- MongoDB running on port `27017`

### 7. Add ESLint and Prettierrc

Initialize ESLint in the specified directory (frontend, backend, or the current directory) to ensure consistent code quality with tailored configurations based on the project type.

```bash
devcli add-eslint [directory] # Set up ESLint in the specified directory (defaults to current directory)
```

#### What This Command Does:

- **Automatically Detects Project Type**: Determines if the project is a React, Vue, TypeScript, Node.js, or plain JavaScript application.
- **Configures ESLint**: Creates a `.eslintrc.json` file specific to the detected environment (e.g., browser for React, Node.js for backend).
- **Installs Dependencies**: Automatically installs ESLint, Prettier, and their necessary plugins as development dependencies in the specified directory.
- **Supports Multiple File Extensions**: Handles various file types based on the project structure.

#### Example Usage

- To set up ESLint in the backend directory:
```bash
devcli add-eslint backend
```
- To set up ESLint in the frontend directory:

```bash
devcli add-eslint frontend
```

- To set up ESLint in the current directory (default):
```bash
devcli add-eslint
```

#### Example Generated ESLint Configuration

This command generates a basic ESLint configuration file (`.eslintrc.json`) that looks like this:

**For Backend Directory:**

```json
{
"env": {
"browser": false,
"node": true,
"es2021": true
},
"extends": ["eslint:recommended", "plugin:prettier/recommended"],
"parserOptions": {
"ecmaVersion": 12
},
"rules": {}
}
```

**For Frontend Directory:**

```json
{
"env": {
"browser": true,
"node": false,
"es2021": true
},
"extends": [
"eslint:recommended",
"plugin:react/recommended",
"plugin:prettier/recommended"
],
"parserOptions": {
"ecmaVersion": 12,
"ecmaFeatures": {
"jsx": true
}
},
"rules": {}
}
```

**For Arbitrary Folders (Defaulting to Node):**

```json
{
"env": {
"browser": false,
"node": true,
"es2021": true
},
"extends": ["eslint:recommended", "plugin:prettier/recommended"],
"parserOptions": {
"ecmaVersion": 12
},
"rules": {}
}
```

#### Benefits

- **Automates Setup**: Saves time by automating the ESLint configuration process based on project type.
- **Ensures Consistency**: Helps maintain consistent linting rules across backend and frontend codebases.
- **Supports Arbitrary Setup**: Allows for easy ESLint configuration in any directory, defaulting to Node.js environment.

### 8. Add JWT Authetication and Authorization
Here is the content for the 8th command, "Add JWT Authentication":

### 8. Add JWT Authentication and Authorization

Add JWT authentication boilerplate to your backend project.

```bash
devcli add-jwt-auth
```

#### What This Command Does:

1. **Creates Necessary Directories**:
- `controllers/authController.js`
- `middlewares/authMiddleware.js`
- `models/userModel.js`
- `routes/authRoutes.js`

2. **Generates Authentication Logic**:
- `authController.js` - Handles user registration and login with JWT token generation.
- `authMiddleware.js` - Implements middleware to authenticate and authorize requests using JWT tokens.
- `userModel.js` - Defines a Mongoose schema for the User model.
- `authRoutes.js` - Defines API routes for authentication, including register, login, and a protected route.

3. **Installs Required Dependencies**:
- `bcryptjs` - For password hashing
- `jsonwebtoken` - For generating and verifying JWT tokens

4. **Integrates Authentication Routes**:
- Adds the authentication routes to the `server.js` file.

5. **Provides Next Steps**:
- Update the `.env` file with a secure `JWT_SECRET`.
- Start the server and test the authentication routes:
- `POST /api/auth/register`: Register a new user
- `POST /api/auth/login`: Log in and get the JWT token
- `GET /api/auth/protected`: Access the protected route with the JWT token

#### Usage:

1. Run the command in your project's `backend` directory:

```bash
devcli add-jwt-auth
```

2. Update the `.env` file in the `backend` directory with a secure `JWT_SECRET`.
3. Start the server and test the authentication routes.

#### Generated Files:

```
backend/
├── controllers/
│ └── authController.js
├── middlewares/
│ └── authMiddleware.js
├── models/
│ └── userModel.js
├── routes/
│ └── authRoutes.js
```

The generated files implement the following functionality:

1. **authController.js**: Handles user registration and login, generating JWT tokens.
2. **authMiddleware.js**: Middleware to authenticate and authorize requests using JWT tokens.
3. **userModel.js**: Mongoose schema and model for the User.
4. **authRoutes.js**: API routes for authentication, including register, login, and a protected route.

After running this command, you can start using the authentication system in your backend application.
