Step-by-Step Implementation

Phase 1: Backend Setup

1. Initialize Backend

mkdir task-management-backend
cd task-management-backend
npm init -y
npm install express mongoose dotenv bcrypt jsonwebtoken express-validator cors helmet express-rate-limit
npm install --save-dev nodemon

2. Database Models

// backend/src/models/User.js
const mongoose = require('mongoose');
const bcrypt = require('bcrypt');

const userSchema = new mongoose.Schema({
    name: {
        type: String,

    getTask,
    createTask,
    updateTask,
    deleteTask
} = require('../controllers/taskController');
const { protect } = require('../middleware/auth');
const { body } = require('express-validator');
const validate = require('../middleware/validate');

const router = express.Router();

router.use(protect);

router.get('/', getTasks);
router.get('/:id', getTask);
router.post(
    '/',
    [
        body('title').trim().notEmpty().withMessage('Task title is required'),
        body('project').notEmpty().withMessage('Project is required')
    ],
    validate,
    createTask
);
router.put('/:id', updateTask);
router.delete('/:id', deleteTask);

module.exports = router;

5. Server Setup

// backend/src/server.js
const express = require('express');
const mongoose = require('mongoose');
const cors = require('cors');
const helmet = require('helmet');
const rateLimit = require('express-rate-limit');
require('dotenv').config();

const authRoutes = require('./routes/authRoutes');
const projectRoutes = require('./routes/projectRoutes');
const taskRoutes = require('./routes/taskRoutes');
const userRoutes = require('./routes/userRoutes');
const errorHandler = require('./middleware/errorHandler');

const app = express();

// Security middleware
app.use(helmet());
app.use(cors({
    origin: process.env.CLIENT_URL || 'http://localhost:3000',
    credentials: true
}));

// Rate limiting
const limiter = rateLimit({
    windowMs: 15 * 60 * 1000, // 15 minutes
    max: 100 // limit each IP to 100 requests per windowMs
});
app.use('/api/', limiter);

// Body parser
app.use(express.json());
app.use(express.urlencoded({ extended: true }));

// Routes
app.use('/api/auth', authRoutes);
app.use('/api/projects', projectRoutes);
app.use('/api/tasks', taskRoutes);
app.use('/api/users', userRoutes);

// Health check
app.get('/api/health', (req, res) => {
    res.json({
        success: true,
        message: 'API is running',
        timestamp: new Date().toISOString()
    });
});

// Error handler (must be last)
app.use(errorHandler);

// Connect to database
mongoose.connect(process.env.MONGODB_URI)
    .then(() => {
        console.log('Connected to MongoDB');
        const PORT = process.env.PORT || 5000;
        app.listen(PORT, () => {
            console.log(`Server running on port ${PORT}`);
        });
    })
    .catch((error) => {
        console.error('MongoDB connection error:', error);
        process.exit(1);
    });

Phase 2: Frontend Setup

1. Initialize Frontend

npx create-react-app task-management-frontend
cd task-management-frontend
npm install axios react-router-dom date-fns

2. API Service

// frontend/src/services/api.js
import axios from 'axios';

const API_URL = process.env.REACT_APP_API_URL || 'http://localhost:5000/api';

const api = axios.create({
    baseURL: API_URL,
    headers: {
        'Content-Type': 'application/json'
    }
});

// Add token to requests
api.interceptors.request.use(
    (config) => {
        const token = localStorage.getItem('token');
        if (token) {
            config.headers.Authorization = `Bearer ${token}`;
        }
        return config;
    },
    (error) => Promise.reject(error)
);

// Handle response errors
api.interceptors.response.use(
    (response) => response,
    (error) => {
        if (error.response?.status === 401) {
            localStorage.removeItem('token');
            window.location.href = '/login';
        }
        return Promise.reject(error);
    }
);

export const authAPI = {
    register: (userData) => api.post('/auth/register', userData),
    login: (credentials) => api.post('/auth/login', credentials),
    getMe: () => api.get('/auth/me')
};

export const projectsAPI = {
    getProjects: () => api.get('/projects'),
    getProject: (id) => api.get(`/projects/${id}`),
    createProject: (data) => api.post('/projects', data),
    updateProject: (id, data) => api.put(`/projects/${id}`, data),
    deleteProject: (id) => api.delete(`/projects/${id}`)
};

export const tasksAPI = {
    getTasks: (params) => api.get('/tasks', { params }),
    getTask: (id) => api.get(`/tasks/${id}`),
    createTask: (data) => api.post('/tasks', data),
    updateTask: (id, data) => api.put(`/tasks/${id}`, data),
    deleteTask: (id) => api.delete(`/tasks/${id}`)
};

export default api;

3. Context Providers

// frontend/src/context/AuthContext.jsx
import { createContext, useContext, useState, useEffect } from 'react';
import { authAPI } from '../services/api';

const AuthContext = createContext();

export function AuthProvider({ children }) {
    const [user, setUser] = useState(null);
    const [loading, setLoading] = useState(true);
    const [token, setToken] = useState(localStorage.getItem('token'));

    useEffect(() => {
        if (token) {
            loadUser();
        } else {
            setLoading(false);
        }
    }, [token]);

    const loadUser = async () => {
        try {
            const response = await authAPI.getMe();
            setUser(response.data.user);
        } catch (error) {
            localStorage.removeItem('token');
            setToken(null);
        } finally {
            setLoading(false);
        }
    };

    const register = async (userData) => {
        try {
            const response = await authAPI.register(userData);
            const { token, user } = response.data;
            localStorage.setItem('token', token);
            setToken(token);
            setUser(user);
            return { success: true };
        } catch (error) {
            return {
                success: false,
                error: error.response?.data?.error || 'Registration failed'
            };
        }
    };

    const login = async (credentials) => {
        try {
            const response = await authAPI.login(credentials);
            const { token, user } = response.data;
            localStorage.setItem('token', token);
            setToken(token);
            setUser(user);
            return { success: true };
        } catch (error) {
            return {
                success: false,
                error: error.response?.data?.error || 'Login failed'
            };
        }
    };

    const logout = () => {
        localStorage.removeItem('token');
        setToken(null);
        setUser(null);
    };

    return (
        <AuthContext.Provider
            value={{
                user,
                loading,
                register,
                login,
                logout,
                isAuthenticated: !!user
            }}
        >
            {children}
        </AuthContext.Provider>
    );
}

export function useAuth() {
    const context = useContext(AuthContext);
    if (!context) {
        throw new Error('useAuth must be used within AuthProvider');
    }
    return context;
}

4. Main Pages

// frontend/src/pages/Dashboard.jsx
import { useState, useEffect } from 'react';
import { Link } from 'react-router-dom';
import { projectsAPI, tasksAPI } from '../services/api';
import { useAuth } from '../context/AuthContext';
import ProjectCard from '../components/ProjectCard';

function Dashboard() {
    const { user } = useAuth();
    const [projects, setProjects] = useState([]);
    const [tasks, setTasks] = useState([]);
    const [loading, setLoading] = useState(true);
    const [stats, setStats] = useState({
        totalProjects: 0,
        totalTasks: 0,
        completedTasks: 0,
        activeTasks: 0
    });

    useEffect(() => {
        loadData();
    }, []);

    const loadData = async () => {
        try {
            setLoading(true);
            const [projectsRes, tasksRes] = await Promise.all([
                projectsAPI.getProjects(),
                tasksAPI.getTasks()
            ]);

            setProjects(projectsRes.data.data.slice(0, 5));
            setTasks(tasksRes.data.data.slice(0, 5));

            const allTasks = tasksRes.data.data;
            setStats({
                totalProjects: projectsRes.data.count,
                totalTasks: allTasks.length,
                completedTasks: allTasks.filter(t => t.status === 'completed').length,
                activeTasks: allTasks.filter(t => t.status !== 'completed').length
            });
        } catch (error) {
            console.error('Failed to load data:', error);
        } finally {
            setLoading(false);
        }
    };

    if (loading) {
        return <Loading />;
    }
