Scientific Calculator

A powerful scientific calculator application that provides an intuitive and advanced mathematical computation experience across desktop platforms.

Features

• Advanced scientific calculations with mathjs integration
• Variable support for complex calculations
• Cross-platform compatibility (Web and Desktop)
• Standalone mode - works without requiring a web server
• Dark mode support

Running the Application

Web Application

To run the application as a web app:

# Start the development server
npm run dev

Visit http://localhost:5000 in your browser to use the application.

Desktop Application (Electron)

There are multiple ways to run the application as a desktop app:

Option 1: With Development Server (recommended for development)

Start the development server first, then run Electron pointing to it:

# Unix/Linux/Mac
./run-electron.sh

# Windows
run-electron.bat

Option 2: Pure Standalone Mode (no server required)

Run the Electron app directly without needing a running server:

# Unix/Linux/Mac
./run-electron-standalone.sh

# Windows
run-electron-standalone.bat

Option 3: All-in-One Development Mode

Start both the development server and Electron app with a single command:

# Unix/Linux/Mac
./dev-electron.sh

# Windows
dev-electron.bat

Development

For detailed information about the Electron setup, see the Electron README.

Technology Stack

• TypeScript React frontend
• Tailwind CSS for responsive design
• Express backend (optional)
• Mathjs for calculations
• Electron for desktop apps

Building for Production

To build the application for production:

# Build the web application
npm run build

# Build the Electron desktop application
./build-electron.sh  # or build-electron.bat on Windows

Troubleshooting

• If you encounter port binding errors, try using the standalone mode instead.
• For permission issues on macOS when building, use sudo or adjust file permissions.
• If Electron can't connect to the server, verify the server is running and no firewalls are blocking port 5000.
