Short description

The final project combines everything: Express routes, Mongoose models, JWT-protected endpoints, validation, and clean project structure.

Steps

1. Create Express app with dotenv, cors, and JSON parsing.
2. Add User + Todo Mongoose models.
3. Implement register/login with JWT.
4. Protect todo CRUD routes with auth middleware.

Todo model + protected route sketch

const todoSchema = new mongoose.Schema({
  title: { type: String, required: true },
  done: { type: Boolean, default: false },
  user: { type: mongoose.Schema.Types.ObjectId, ref: 'User', required: true },
}, { timestamps: true });

app.get('/api/todos', auth, async (req, res) => {
  const todos = await Todo.find({ user: req.user.sub }).sort('-createdAt');
  res.json(todos);
});

app.post('/api/todos', auth, async (req, res) => {
  const todo = await Todo.create({ title: req.body.title, user: req.user.sub });
  res.status(201).json(todo);
});
