📊 Database Schema (MongoDB with Mongoose)

// User Schema
const userSchema = new mongoose.Schema({
  name: { type: String, required: true },
  email: { type: String, required: true, unique: true },
  password: { type: String, required: true },
  image: { type: String },
  bio: { type: String },
  followers: [{ type: mongoose.Schema.Types.ObjectId, ref: "User" }],
  following: [{ type: mongoose.Schema.Types.ObjectId, ref: "User" }],
  bookmarks: [{ type: mongoose.Schema.Types.ObjectId, ref: "Article" }],
  createdAt: { type: Date, default: Date.now },
});

// Article Schema
const articleSchema = new mongoose.Schema({
  title: { type: String, required: true },
  content: { type: String, required: true },
  slug: { type: String, unique: true, required: true },
  authorId: {
    type: mongoose.Schema.Types.ObjectId,
    ref: "User",
    required: true,
  },
  tags: [{ type: String }],
  published: { type: Boolean, default: false },
  views: { type: Number, default: 0 },
  likes: [{ type: mongoose.Schema.Types.ObjectId, ref: "User" }],
  comments: [{ type: mongoose.Schema.Types.ObjectId, ref: "Comment" }],
  createdAt: { type: Date, default: Date.now },
  updatedAt: { type: Date, default: Date.now },
});

// Comment Schema
const commentSchema = new mongoose.Schema({
  content: { type: String, required: true },
  authorId: {
    type: mongoose.Schema.Types.ObjectId,
    ref: "User",
    required: true,
  },
  articleId: {
    type: mongoose.Schema.Types.ObjectId,
    ref: "Article",
    required: true,
  },
  parentCommentId: { type: mongoose.Schema.Types.ObjectId, ref: "Comment" },
  likes: [{ type: mongoose.Schema.Types.ObjectId, ref: "User" }],
  createdAt: { type: Date, default: Date.now },
});

🔐 Authentication Implementation

// JWT Authentication Middleware
const jwt = require("jsonwebtoken");

const authMiddleware = async (req, res, next) => {
  try {
    const token = req.headers.authorization?.split(" ")[1];
    if (!token) return res.status(401).json({ message: "Unauthorized" });

    const decoded = jwt.verify(token, process.env.JWT_SECRET);
    const user = await User.findById(decoded.userId);
    if (!user) return res.status(401).json({ message: "User not found" });

    req.user = user;
    next();
  } catch (error) {
    res.status(401).json({ message: "Invalid token" });
  }
};

// Login Controller
const login = async (req, res) => {
  try {
    const { email, password } = req.body;
    const user = await User.findOne({ email });

    if (!user || !(await bcrypt.compare(password, user.password))) {
      return res.status(401).json({ message: "Invalid credentials" });
    }

    const token = jwt.sign({ userId: user._id }, process.env.JWT_SECRET, {
      expiresIn: "7d",
    });

    res.json({
      token,
      user: { id: user._id, name: user.name, email: user.email },
    });
  } catch (error) {
    res.status(500).json({ message: "Server error" });
  }
};

📝 Article API Controller

const createArticle = async (req, res) => {
  try {
    const { title, content, tags } = req.body;
    const slug = title.toLowerCase().replace(/\s+/g, "-");

    const article = new Article({
      title,
      content,
      slug,
      authorId: req.user._id,
      tags,
    });

    await article.save();
    res.status(201).json(article);
  } catch (error) {
    res.status(500).json({ message: "Failed to create article" });
  }
};

const getArticles = async (req, res) => {
  try {
    const { page = 1, limit = 10, tag } = req.query;
    const query = tag ? { tags: tag, published: true } : { published: true };

    const articles = await Article.find(query)
      .populate("authorId", "name image")
      .sort({ createdAt: -1 })
      .limit(limit * 1)
      .skip((page - 1) * limit);

    res.json(articles);
  } catch (error) {
    res.status(500).json({ message: "Failed to fetch articles" });
  }
};

🔄 Real-time Features with Socket.io

// Server-side Socket.io setup
const io = require("socket.io")(server, {
  cors: { origin: "http://localhost:3000" },
});

io.on("connection", (socket) => {
  socket.on("join-room", (articleId) => {
    socket.join(articleId);
  });

  socket.on("new-comment", ({ articleId, comment }) => {
    io.to(articleId).emit("comment-added", comment);
  });

  socket.on("like-article", ({ articleId, userId }) => {
    io.emit("article-liked", { articleId, userId });
  });
});
