The application follows the MVC (Model-View-Controller) pattern:

• Models: Represented by Firebase Firestore collections
• Views: Frontend HTML/CSS/JS
• Controllers: Handle business logic and Firebase interactions

Authentication Flow

    Client->>Server: POST /api/auth/login
    Server->>Firebase: Authenticate
    Firebase-->>Server: Auth token
    Server->>Server: Generate JWT
    Server-->>Client: Return JWT + user data
    Client->>Client: Store JWT in localStorage

Firebase Integration

BlogFire leverages Firebase services for various functionalities:

Authentication

Firebase Authentication provides secure user management with features like:

• Email/password authentication
• Social provider integration
• Password reset
• Email verification

Firestore Database

The application uses Firestore for storing:

• User profiles
• Blog posts
• Comments
• Categories and tags

Example Database Schema

Users Collection

users/
  ├── userId1/
  │   ├── name: "Utso Sarkar"
  │   ├── email: "utsosarkar1@gmail.com"
  │   ├── role: "author"
  │   ├── avatar: "https://storage.url/avatar1.jpg"
  │   └── createdAt: Timestamp
  └── userId2/
      └── ...

Posts Collection

posts/
  ├── postId1/
  │   ├── title: "My First Post"
  │   ├── content: "Content in HTML format"
  │   ├── authorId: "userId1"
  │   ├── imageUrl: "https://storage.url/image1.jpg"
  │   ├── category: "technology"
  │   ├── tags: ["javascript", "firebase"]
  │   ├── published: true
  │   ├── createdAt: Timestamp
  │   └── updatedAt: Timestamp
  └── postId2/
      └── ...

Firebase Storage

Used for storing:

• User avatars
• Post featured images
• Embedded content images

Authentication System

The authentication system uses JWT tokens for maintaining user sessions:

// Example of JWT token generation
const generateToken = (user) => {
  return jwt.sign(
    { uid: user.uid, email: user.email },
    process.env.JWT_SECRET,
    { expiresIn: '7d' }
  );
};

File Upload System

BlogFire includes a robust file upload system using Multer middleware and Firebase Storage:

// Example of file upload middleware
const multer = require('multer');
const storage = multer.memoryStorage();
const upload = multer({
  storage,
  limits: { fileSize: 5 * 1024 * 1024 }, // 5MB limit
  fileFilter: (req, file, cb) => {
    if (file.mimetype.startsWith('image/')) {
      cb(null, true);
    } else {
      cb(new Error('Only images are allowed'));
    }
  }
});

Error Handling

The application implements a centralized error handling system:

// Example error handler middleware
const errorHandler = (err, req, res, next) => {
  const statusCode = err.statusCode || 500;
  
  res.status(statusCode).json({
    success: false,
    error: {
      message: err.message || 'Server Error',
      stack: process.env.NODE_ENV === 'development' ? err.stack : undefined
    }
  });
};

Responsive Design

The frontend implements responsive design principles:

Breakpoints

Device	Width Range	Class Prefix
Mobile	< 768px	.mobile-
Tablet	768px - 1023px	.tablet-
Desktop	1024px - 1439px	.desktop-
Large Desktop	≥ 1440px	.large-
