const ProtectedRoute = ({ children, requiredRole }) => {
  const token = localStorage.getItem('token');
  const user = JSON.parse(localStorage.getItem('user') || '{}');

  if (!token) {
    return <Navigate to="/login" />;
  }

  if (requiredRole && user.role !== requiredRole) {
    return <Navigate to="/unauthorized" />;
  }

  return children;
};

export default ProtectedRoute;

// Usage in App.js
import { BrowserRouter, Routes, Route } from 'react-router-dom';

function App() {
  return (
    <BrowserRouter>
      <Routes>
        <Route path="/login" element={<Login />} />
        <Route path="/dashboard" element={
          <ProtectedRoute>
            <UserDashboard />
          </ProtectedRoute>
        } />
        <Route path="/admin" element={
          <ProtectedRoute requiredRole="admin">
            <AdminDashboard />
          </ProtectedRoute>
        } />
      </Routes>
    </BrowserRouter>
  );
}

Kanban Board Component

import React, { useState, useEffect } from 'react';

const KanbanBoard = ({ userId }) => {
  const [tasks, setTasks] = useState({ todo: [], inProgress: [], done: [] });

  useEffect(() => {
    fetchTasks();
  }, [userId]);

  const fetchTasks = async () => {
    const token = localStorage.getItem('token');
    const response = await fetch(`http://localhost:5000/api/tasks/user/${userId}`, {
      headers: { 'Authorization': `Bearer ${token}` }
    });
    const data = await response.json();
    
    // Organize tasks by status
    const organized = {
      todo: data.filter(t => t.status === 'todo'),
      inProgress: data.filter(t => t.status === 'in-progress'),
      done: data.filter(t => t.status === 'done')
    };
    setTasks(organized);
  };

  const moveTask = async (taskId, newStatus) => {
    const token = localStorage.getItem('token');
    await fetch(`http://localhost:5000/api/tasks/${taskId}/status`, {
      method: 'PATCH',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${token}`
      },
      body: JSON.stringify({ status: newStatus })
    });
    fetchTasks(); // Refresh board
  };

  return (
    <div className="kanban-board">
      <Column title="To Do" tasks={tasks.todo} targetStatus="in-progress" />
      <Column title="In Progress" tasks={tasks.inProgress} targetStatus="done" />
      <Column title="Done" tasks={tasks.done} />
    </div>
  );
};

Time Tracking Hook

import { useState, useEffect } from 'react';

const useTimeTracker = (taskId) => {
  const [isTracking, setIsTracking] = useState(false);
  const [elapsedTime, setElapsedTime] = useState(0);

  useEffect(() => {
    let interval;
    if (isTracking) {
      interval = setInterval(() => {
        setElapsedTime(prev => prev + 1);
      }, 1000);
    }
    return () => clearInterval(interval);
  }, [isTracking]);

  const startTracking = () => {
    setIsTracking(true);
  };

  const stopTracking = async () => {
    setIsTracking(false);
    
    // Log time to backend
    const token = localStorage.getItem('token');
    await fetch(`http://localhost:5000/api/tasks/${taskId}/log-time`, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${token}`
      },
      body: JSON.stringify({ duration: elapsedTime })
    });
  };

  const resetTracking = () => {
    setElapsedTime(0);
    setIsTracking(false);
  };

  return { isTracking, elapsedTime, startTracking, stopTracking, resetTracking };
};

export default useTimeTracker;

AI-Powered User Analytics Dashboard

const UserAnalyticsDashboard = ({ userId }) => {
  const [analytics, setAnalytics] = useState({
    riskScore: null,
    burnoutRisk: null,
    anomalies: []
  });

  useEffect(() => {
    fetchAnalytics();
  }, [userId]);

  const fetchAnalytics = async () => {
    try {
      // Fetch risk prediction
      const riskRes = await fetch('http://localhost:8000/predict/risk', {

Configuration

Backend Configuration (backend/config.js)

module.exports = {
  port: process.env.PORT || 5000,
  mongoURI: process.env.MONGODB_URI,
  jwtSecret: process.env.JWT_SECRET,
  jwtExpire: process.env.JWT_EXPIRE || '7d',
  mlServiceURL: process.env.ML_SERVICE_URL || 'http://localhost:8000',
  
  // Rate limiting
  rateLimitWindowMs: 15 * 60 * 1000, // 15 minutes
  rateLimitMax: 100,
  
  // File upload
  maxFileSize: 5 * 1024 * 1024, // 5MB
  
  // Email (if configured)
  emailService: process.env.EMAIL_SERVICE,
  emailUser: process.env.EMAIL_USER,
  emailPassword: process.env.EMAIL_PASSWORD
};

ML Service Configuration

Create ml-service/config.py:

import os
from dotenv import load_dotenv

load_dotenv()

class Config:
    MONGODB_URI = os.getenv('MONGODB_URI', 'mongodb://localhost:27017/enterprise-user-mgmt')
    MODEL_PATH = os.getenv('MODEL_PATH', './models')
    LOG_LEVEL = os.getenv('LOG_LEVEL', 'INFO')
    
    # ML Model Parameters
    RISK_THRESHOLD = 0.7
    ANOMALY_THRESHOLD = 0.5
    BURNOUT_THRESHOLD = 0.6
    
    # Online learning
    RETRAIN_INTERVAL = 86400  # 24 hours in seconds
    MIN_SAMPLES_RETRAIN = 100

config = Config()

Troubleshooting

Issue: JWT Token Expired

// Add token refresh logic
const refreshToken = async () => {
  const refreshToken = localStorage.getItem('refreshToken');
  const response = await fetch('http://localhost:5000/api/auth/refresh', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ refreshToken })
  });
  const data = await response.json();
  localStorage.setItem('token', data.token);
  return data.token;
};

// Axios interceptor for auto-refresh
import axios from 'axios';

axios.interceptors.response.use(
  response => response,
  async error => {
    if (error.response?.status === 401) {
      try {
        const newToken = await refreshToken();
        error.config.headers.Authorization = `Bearer ${newToken}`;
        return axios(error.config);
      } catch (refreshError) {
        // Redirect to login
        window.location.href = '/login';
      }
    }
    return Promise.reject(error);
  }
);

Issue: ML Service Connection Failed

// Add fallback when ML service is unavailable
const getPredictionWithFallback = async (endpoint, data) => {
  try {
    const response = await fetch(`http://localhost:8000${endpoint}`, {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify(data),
      timeout: 5000
    });
    
    if (!response.ok) throw new Error('ML service error');
    return await response.json();
  } catch (error) {
    console.warn('ML service unavailable, using fallback:', error);
    // Return default/cached predictions
    return { 
      available: false, 
      message: 'AI analytics temporarily unavailable' 
    };
  }
};

Issue: MongoDB Connection Error

// backend/db.js - Add retry logic
const mongoose = require('mongoose');

const connectDB = async (retries = 5) => {
  try {
    await mongoose.connect(process.env.MONGODB_URI, {
      useNewUrlParser: true,
      useUnifiedTopology: true,
      serverSelectionTimeoutMS: 5000
    });
    console.log('MongoDB Connected');
  } catch (error) {
    console.error('MongoDB connection error:', error);
    
    if (retries > 0) {
      console.log(`Retrying connection... (${retries} attempts left)`);
      setTimeout(() => connectDB(retries - 1), 5000);
    } else {
      process.exit(1);
    }
  }
};

module.exports = connectDB;

Issue: CORS Errors

// backend/server.js - Configure CORS properly
const express = require('express');
const cors = require('cors');

const app = express();

app.use(cors({
  origin: process.env.FRONTEND_URL || 'http://localhost:3000',
  credentials: true,
  methods: ['GET', 'POST', 'PUT', 'DELETE', 'PATCH'],
  allowedHeaders: ['Content-Type', 'Authorization']
}));

Issue: Model Performance Degradation

# ml-service/main.py - Add model monitoring
from datetime import datetime
import logging

class ModelMonitor:
    def __init__(self):
        self.predictions = []
        self.performance_log = []

            'prediction': prediction,
            'actual': actual
        }
        self.predictions.append(entry)
        
        # Check if model needs retraining
        if len(self.predictions) >= 100:
            self.evaluate_performance()
    
    def evaluate_performance(self):
        # Calculate accuracy, drift, etc.
        if self.should_retrain():
