Setting Up Smart Contact Manager Application

Database Information

Database Name: contact_manager.db (SQLite database)

SQLite is a file-based database, so you don't need to install a separate database server. The database file will be created automatically when you run the application for the first time.

Complete Setup Guide

1. Project Structure

First, create the following directory structure:

smart-contact-manager/
├── backend/
│   ├── app.py
│   ├── schema.sql
│   ├── config.py
│   └── requirements.txt
└── frontend/
    ├── public/
    ├── src/
    │   ├── api/
    │   │   └── config.js
    └── package.json

2. Backend Setup

Install Python and Required Packages

Make sure you have Python 3.8+ installed. You can check with:
python --version
Create a virtual environment in the backend directory:
cd smart-contact-manager/backend python -m venv venv
Activate the virtual environment:
- On Windows:
  venv\Scripts\activate
- On macOS/Linux:
  source venv/bin/activate
Create a requirements.txt file with the following content:
Flask==2.2.3 Flask-Cors==3.0.10 Werkzeug==2.2.3 PyJWT==2.6.0 python-dotenv==1.0.0
Install the required packages:
pip install -r requirements.txt

Create Configuration File

Create a config.py file in the backend directory:

import os
from dotenv import load_dotenv

# Load environment variables from .env file
load_dotenv()

class Config:
    SECRET_KEY = os.environ.get('SECRET_KEY') or 'your-secret-key-here'
    DATABASE_PATH = os.path.join(os.path.dirname(__file__), 'contact_manager.db')
    JWT_EXPIRATION_DAYS = 7
    DEBUG = True

Create Database Schema

Save the SQL schema from my previous response to schema.sql in the backend directory.

Create Flask Application

Create app.py in the backend directory:

from flask import Flask, jsonify, request, g
from flask_cors import CORS
from werkzeug.security import generate_password_hash, check_password_hash
import sqlite3
import os
from datetime import datetime, timedelta
import jwt
from functools import wraps
from config import Config

app = Flask(__name__)
CORS(app)

# Configuration
app.config.from_object(Config)

# Database helpers
def get_db():
    db = getattr(g, '_database', None)
    if db is None:
        db = g._database = sqlite3.connect(app.config['DATABASE_PATH'])
        db.row_factory = sqlite3.Row
    return db

@app.teardown_appcontext
def close_connection(exception):
    db = getattr(g, '_database', None)
    if db is not None:
        db.close()

def init_db():
    with app.app_context():
        db = get_db()
        with app.open_resource('schema.sql', mode='r') as f:
            db.executescript(f.read().decode('utf8'))
        db.commit()

# Token verification decorator
def token_required(f):
    @wraps(f)
    def decorated(*args, **kwargs):
        token = None
        
        if 'Authorization' in request.headers:
            auth_header = request.headers['Authorization']
            token = auth_header.split(" ")[1] if len(auth_header.split(" ")) > 1 else None
        
        if not token:
            return jsonify({'message': 'Token is missing'}), 401
        
        try:
            data = jwt.decode(token, app.config['SECRET_KEY'], algorithms=["HS256"])
            db = get_db()
            current_user = db.execute('SELECT * FROM users WHERE id = ?', (data['user_id'],)).fetchone()
        except:
            return jsonify({'message': 'Token is invalid'}), 401
        
        return f(current_user, *args, **kwargs)
    
    return decorated

    db = get_db()
    
    # Check if user already exists
    existing_user = db.execute('SELECT * FROM users WHERE email = ?', (data['email'],)).fetchone()
    if existing_user:
        return jsonify({'message': 'User already exists'}), 409
    
    # Create new user
    hashed_password = generate_password_hash(data['password'])
    
    db.execute('''
        INSERT INTO users (name, email, password, created_at)
        VALUES (?, ?, ?, ?)
    ''', (
        data['name'],
        data['email'],
        hashed_password,

        token = jwt.encode({
            'user_id': user['id'],
            'exp': token_expiry
        }, app.config['SECRET_KEY'], algorithm="HS256")
        
        return jsonify({

def initialize_db_command():
    init_db()
    print('Database initialized.')

if __name__ == '__main__':
    app.run(debug=app.config['DEBUG'])

3. Frontend Setup

Install Node.js and Create React App

Make sure you have Node.js (14+) and npm installed. You can check with:
node --version npm --version
Navigate to the frontend directory:
cd smart-contact-manager/frontend
Create a new React app:
npx create-react-app .
Install additional dependencies:
npm install axios react-router-dom chart.js react-chartjs-2

Configure API Connection

Create or update src/api/config.js:

// API base URL - change this to match your backend server
export const API_URL = "http://localhost:5000";

Create src/api/auth.js:

import { API_URL } from "./config";

export const register = async (userData) => {
  try {
    const response = await fetch(`${API_URL}/api/auth/register`, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify(userData),
    });

    const data = await response.json();

    if (!response.ok) {
      throw new Error(data.message || "Registration failed");
    }

    return data;
  } catch (error) {
    throw error;
  }
};

export const login = async (credentials) => {
  try {
    const response = await fetch(`${API_URL}/api/auth/login`, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify(credentials),
    });

    const data = await response.json();

    if (!response.ok) {
      throw new Error(data.message || "Login failed");
    }

    // Store token in localStorage
    localStorage.setItem("token", data.token);
    localStorage.setItem("user", JSON.stringify(data.user));

    return data;
  } catch (error) {
    throw error;
  }
};

export const logout = () => {
  localStorage.removeItem("token");
  localStorage.removeItem("user");
};

export const getAuthHeader = () => {
  const token = localStorage.getItem("token");
  return token ? { Authorization: `Bearer ${token}` } : {};
};

export const isAuthenticated = () => {
  return localStorage.getItem("token") !== null;
};

4. Running the Application

Create Environment File

Create a .env file in the backend directory:

SECRET_KEY=your-super-secret-key-change-this-in-production

Start the Backend Server

Navigate to the backend directory:
cd smart-contact-manager/backend
Activate the virtual environment if not already activated:
- On Windows:
  venv\Scripts\activate
- On macOS/Linux:
  source venv/bin/activate
Initialize the database (first time only):
flask init-db
Start the Flask server:
flask run
The server will run on http://localhost:5000

Start the Frontend Development Server

Open a new terminal window/tab
Navigate to the frontend directory:
cd smart-contact-manager/frontend
Start the React development server:
npm start
The application will be available at http://localhost:3000

5. Testing the Connection

Open your browser and navigate to http://localhost:3000
Try to register a new user
Log in with the registered user
If everything is set up correctly, you should be able to access the dashboard

6. Troubleshooting

CORS Issues

If you encounter CORS issues, make sure the Flask CORS is properly configured. You might need to update the CORS configuration in app.py:

CORS(app, resources={r"/api/*": {"origins": "http://localhost:3000"}})

Database Connection Issues

If you have issues with the database:

Delete the database file and reinitialize:
rm contact_manager.db flask init-db
Check if SQLite is working properly:
sqlite3 contact_manager.db .tables .exit

API Connection Issues

If the frontend can't connect to the backend:

Check that both servers are running
Verify the API_URL in src/api/config.js matches your backend server address
Check the browser console for any error messages

7. Production Deployment

For production deployment:

Set DEBUG = False in config.py
Use a proper web server like Gunicorn for the backend:
pip install gunicorn gunicorn app:app
Build the React app for production:
npm run build
Serve the built files using a web server like Nginx or Apache

This setup provides a complete development environment for the Smart Contact Manager application with proper connections between the frontend, backend, and SQLite database. The application is ready for development and can be extended with additional features as needed.

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    "./src/**/*.{js,jsx}",
    "./public/index.html",
  ],
  theme: {
    extend: {
      colors: {
        purple: {
          50: "#f5f3ff",
          100: "#ede9fe",
          200: "#ddd6fe",
          300: "#c4b5fd",
          400: "#a78bfa",
          500: "#8b5cf6",
          600: "#7c3aed",
          700: "#6d28d9",
          800: "#5b21b6",
          900: "#4c1d95",
        },
      },
    },
  },
  plugins: [],
}

3. Update CSS

Create or update src/index.css:

@tailwind base;
@tailwind components;
@tailwind utilities;

body {
  margin: 0;
  font-family: "Inter", -apple-system, BlinkMacSystemFont, "Segoe UI", "Roboto", "Oxygen", "Ubuntu", "Cantarell",
    "Fira Sans", "Droid Sans", "Helvetica Neue", sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  background-color: #f9fafb;
}

.animate-fade-in {
  animation: fadeIn 0.5s ease-in-out;
}

@keyframes fadeIn {
  from {
    opacity: 0;
    transform: translateY(10px);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}

Additional Setup Notes

Database Backup and Restore
To backup the database:
mysqldump -u root -p smart_contact_manager > backup.sql
To restore the database:
mysql -u root -p smart_contact_manager < backup.sql
Production Deployment
For production deployment:
- Set DEBUG=False in the .env file
- Use a proper web server like Gunicorn for the backend
- Build the React app for production with npm run build
- Serve the built files using a web server like Nginx or Apache
- Set up proper SSL certificates for HTTPS
Security Considerations
- Store sensitive information like database credentials in environment variables
- Use strong, unique passwords for database users
- Implement rate limiting for API endpoints
- Regularly update dependencies to patch security vulnerabilities
- Consider implementing CSRF protection for form submissions

This setup provides a complete development environment for the Smart Contact Manager application with proper connections between the React frontend, Flask backend, and MySQL database. The application is ready for development and can be extended with additional features as needed.

You can send messages while the preview loads

Code editing is not availableDuplicate this chat to use a more powerful code editor.

Loading integrations...

tell me databae name also and also tell how to set up this on my pc and run this and with proper connection of frontend backend and databse

Setting Up Smart Contact Manager Application

Database Information

Database Name: contact_manager.db (SQLite database)

SQLite is a file-based database, so you don't need to install a separate database server. The database file will be created automatically when you run the application for the first time.

Complete Setup Guide

1. Project Structure

First, create the following directory structure:

smart-contact-manager/
├── backend/
│   ├── app.py
│   ├── schema.sql
│   ├── config.py
│   └── requirements.txt
└── frontend/
    ├── public/
    ├── src/
    │   ├── api/
    │   │   └── config.js
    └── package.json

2. Backend Setup

Install Python and Required Packages

Make sure you have Python 3.8+ installed. You can check with:
python --version
Create a virtual environment in the backend directory:
cd smart-contact-manager/backend python -m venv venv
Activate the virtual environment:
- On Windows:
  venv\Scripts\activate
- On macOS/Linux:
  source venv/bin/activate
Create a requirements.txt file with the following content:
Flask==2.2.3 Flask-Cors==3.0.10 Werkzeug==2.2.3 PyJWT==2.6.0 python-dotenv==1.0.0
Install the required packages:
pip install -r requirements.txt

Create Configuration File

Create a config.py file in the backend directory:

import os
from dotenv import load_dotenv

# Load environment variables from .env file
load_dotenv()

class Config:
    SECRET_KEY = os.environ.get('SECRET_KEY') or 'your-secret-key-here'
    DATABASE_PATH = os.path.join(os.path.dirname(__file__), 'contact_manager.db')
    JWT_EXPIRATION_DAYS = 7
    DEBUG = True

Create Database Schema

Save the SQL schema from my previous response to schema.sql in the backend directory.

Create Flask Application

Create app.py in the backend directory:

from flask import Flask, jsonify, request, g
from flask_cors import CORS
from werkzeug.security import generate_password_hash, check_password_hash
import sqlite3
import os
from datetime import datetime, timedelta
import jwt
from functools import wraps
from config import Config

app = Flask(__name__)
CORS(app)

# Configuration
app.config.from_object(Config)

# Database helpers
def get_db():
    db = getattr(g, '_database', None)
    if db is None:
        db = g._database = sqlite3.connect(app.config['DATABASE_PATH'])
        db.row_factory = sqlite3.Row
    return db

@app.teardown_appcontext
def close_connection(exception):
    db = getattr(g, '_database', None)
    if db is not None:
        db.close()

3. Frontend Setup

Install Node.js and Create React App

Make sure you have Node.js (14+) and npm installed. You can check with:
node --version npm --version
Navigate to the frontend directory:
cd smart-contact-manager/frontend
Create a new React app:
npx create-react-app .
Install additional dependencies:
npm install axios react-router-dom chart.js react-chartjs-2

Configure API Connection

Create or update src/api/config.js:

// API base URL - change this to match your backend server
export const API_URL = "http://localhost:5000";

Create src/api/auth.js:

import { API_URL } from "./config";

export const register = async (userData) => {
  try {
    const response = await fetch(`${API_URL}/api/auth/register`, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify(userData),
    });

    const data = await response.json();

    if (!response.ok) {
      throw new Error(data.message || "Registration failed");
    }

    return data;
  } catch (error) {
    throw error;
  }
};

export const login = async (credentials) => {
  try {
    const response = await fetch(`${API_URL}/api/auth/login`, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify(credentials),
    });

    const data = await response.json();

    if (!response.ok) {
      throw new Error(data.message || "Login failed");
    }

    // Store token in localStorage
    localStorage.setItem("token", data.token);
    localStorage.setItem("user", JSON.stringify(data.user));

    return data;
  } catch (error) {
    throw error;
  }
};

export const logout = () => {
  localStorage.removeItem("token");
  localStorage.removeItem("user");
};

export const getAuthHeader = () => {
  const token = localStorage.getItem("token");
  return token ? { Authorization: `Bearer ${token}` } : {};
};

export const isAuthenticated = () => {
  return localStorage.getItem("token") !== null;
};

4. Running the Application

Create Environment File

Create a .env file in the backend directory:

SECRET_KEY=your-super-secret-key-change-this-in-production

Start the Backend Server

Navigate to the backend directory:
cd smart-contact-manager/backend
Activate the virtual environment if not already activated:
- On Windows:
  venv\Scripts\activate
- On macOS/Linux:
  source venv/bin/activate
Initialize the database (first time only):
flask init-db
Start the Flask server:
flask run
The server will run on http://localhost:5000

Start the Frontend Development Server

Open a new terminal window/tab
Navigate to the frontend directory:
cd smart-contact-manager/frontend
Start the React development server:
npm start
The application will be available at http://localhost:3000

5. Testing the Connection

Open your browser and navigate to http://localhost:3000
Try to register a new user
Log in with the registered user
If everything is set up correctly, you should be able to access the dashboard

6. Troubleshooting

CORS Issues

If you encounter CORS issues, make sure the Flask CORS is properly configured. You might need to update the CORS configuration in app.py:

CORS(app, resources={r"/api/*": {"origins": "http://localhost:3000"}})

Database Connection Issues

If you have issues with the database:

Delete the database file and reinitialize:
rm contact_manager.db flask init-db
Check if SQLite is working properly:
sqlite3 contact_manager.db .tables .exit

API Connection Issues

If the frontend can't connect to the backend:

Check that both servers are running
Verify the API_URL in src/api/config.js matches your backend server address
Check the browser console for any error messages

7. Production Deployment

For production deployment:

Set DEBUG = False in config.py
Use a proper web server like Gunicorn for the backend:
pip install gunicorn gunicorn app:app
Build the React app for production:
npm run build
Serve the built files using a web server like Nginx or Apache

def initialize_db_command():
    init_db()
    print('Database initialized.')

if __name__ == '__main__':
    app.run(debug=app.config['DEBUG'])

4. Create Environment File

Create .env file in the backend directory:

SECRET_KEY=your-super-secret-key-change-this-in-production
DEBUG=True
MYSQL_HOST=localhost
MYSQL_USER=root
MYSQL_PASSWORD=your_mysql_password
MYSQL_DB=smart_contact_manager
JWT_EXPIRATION_DAYS=7

Frontend Setup

1. Create React App with Tailwind CSS

npx create-react-app frontend
cd frontend
npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p

2. Configure Tailwind CSS

Update tailwind.config.js:

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    "./src/**/*.{js,jsx}",
    "./public/index.html",
  ],
  theme: {
    extend: {
      colors: {
        purple: {
          50: "#f5f3ff",
          100: "#ede9fe",
          200: "#ddd6fe",
          300: "#c4b5fd",
          400: "#a78bfa",
          500: "#8b5cf6",
          600: "#7c3aed",
          700: "#6d28d9",
          800: "#5b21b6",
          900: "#4c1d95",
        },
      },
    },
  },
  plugins: [],
}

3. Update CSS

Create or update src/index.css:

@tailwind base;
@tailwind components;
@tailwind utilities;

body {
  margin: 0;
  font-family: "Inter", -apple-system, BlinkMacSystemFont, "Segoe UI", "Roboto", "Oxygen", "Ubuntu", "Cantarell",
    "Fira Sans", "Droid Sans", "Helvetica Neue", sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  background-color: #f9fafb;
}

.animate-fade-in {
  animation: fadeIn 0.5s ease-in-out;
}

@keyframes fadeIn {
  from {
    opacity: 0;
    transform: translateY(10px);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}

.animate-scale {
  transition: transform 0.3s ease;
}

.animate-scale:hover {
  transform: scale(1.03);
}

UPDATE users SET name = ?, phone = ?, bio = ?, updated_at = NOW() WHERE id = ?;

Contact Operations

-- Get all contacts for a user
SELECT c.*, cat.name as category_name 
FROM contacts c
LEFT JOIN categories cat ON c.category_id = cat.id
WHERE c.user_id = ? 
ORDER BY c.name;

-- Get favorite contacts
SELECT c.*, cat.name as category_name 
FROM contacts c
LEFT JOIN categories cat ON c.category_id = cat.id
WHERE c.user_id = ? AND c.is_favorite = TRUE
ORDER BY c.name;

-- Search contacts
SELECT c.*, cat.name as category_name 
FROM contacts c
LEFT JOIN categories cat ON c.category_id = cat.id
WHERE c.user_id = ? AND 
      (c.name LIKE ? OR c.email LIKE ? OR c.number LIKE ?)
ORDER BY c.name;

-- Get contacts by category
SELECT c.*, cat.name as category_name 
FROM contacts c
LEFT JOIN categories cat ON c.category_id = cat.id
WHERE c.user_id = ? AND cat.name = ?
ORDER BY c.name;

-- Get upcoming birthdays
SELECT c.*, cat.name as category_name 
FROM contacts c
LEFT JOIN categories cat ON c.category_id = cat.id
WHERE c.user_id = ? AND c.birthday IS NOT NULL
ORDER BY 
    CASE 
        WHEN MONTH(c.birthday) > MONTH(CURDATE()) OR 
             (MONTH(c.birthday) = MONTH(CURDATE()) AND DAY(c.birthday) >= DAY(CURDATE()))
        THEN 0
        ELSE 1
    END,
    MONTH(c.birthday),
    DAY(c.birthday)
LIMIT 10;

Document Operations

-- Add a new document
INSERT INTO documents (user_id, name, description, file_name, file_type, file_size, file_path, icon)
VALUES (?, ?, ?, ?, ?, ?, ?, ?);

-- Get all documents for a user
SELECT * FROM documents WHERE user_id = ? ORDER BY created_at DESC;

-- Delete a document
DELETE FROM documents WHERE id = ? AND user_id = ?;

Message Operations

-- Get all messages between user and contact
SELECT * FROM messages 
WHERE user_id = ? AND contact_id = ?
ORDER BY created_at;

-- Send a new message
INSERT INTO messages (user_id, contact_id, content, is_from_user)
VALUES (?, ?, ?, ?);

-- Mark messages as read
UPDATE messages 
SET is_read = TRUE 
WHERE user_id = ? AND contact_id = ? AND is_from_user = FALSE;

-- Get unread message count
SELECT COUNT(*) as unread_count 
FROM messages 
WHERE user_id = ? AND is_read = FALSE AND is_from_user = FALSE;

-- Contact distribution by category
SELECT cat.name, COUNT(c.id) as count
FROM contacts c
JOIN categories cat ON c.category_id = cat.id
WHERE c.user_id = ?
GROUP BY cat.name;

-- Monthly contact additions
SELECT 
    YEAR(created_at) as year,
    MONTH(created_at) as month,
    COUNT(*) as count
FROM contacts
WHERE user_id = ?
GROUP BY YEAR(created_at), MONTH(created_at)
ORDER BY YEAR(created_at), MONTH(created_at);

-- Birthday distribution by month
SELECT 
    MONTH(birthday) as month,
    COUNT(*) as count
FROM contacts
WHERE user_id = ? AND birthday IS NOT NULL
GROUP BY MONTH(birthday)
ORDER BY MONTH(birthday);

Additional Setup Notes

Database Backup and Restore
To backup the database:
mysqldump -u root -p smart_contact_manager > backup.sql
To restore the database:
mysql -u root -p smart_contact_manager < backup.sql
Production Deployment
For production deployment:
- Set DEBUG=False in the .env file
- Use a proper web server like Gunicorn for the backend
- Build the React app for production with npm run build
- Serve the built files using a web server like Nginx or Apache
- Set up proper SSL certificates for HTTPS
