How To Build

FastCGI mode

This build uses PHP in FastCGI mode (php-cgi / php-fpm) and an internal HTTP → FastCGI proxy. By default the app spawns php-cgi -b 127.0.0.1:9000 and the proxy listens on the port configured in ui/config.json (the php.fastcgi_port and php.port fields). Ensure php-cgi (or an equivalent FastCGI-capable PHP binary) is present in the supplied ui/php directory or available on PATH.

Make sure you have Node.js v22+ installed and the Rust toolchain (required by Tauri). Then follow these steps to build PHP Fiddle from source:

# Clone the project and navigate to the directory
git clone https://github.com/timint/phpfiddle.git && cd phpfiddle

# Install Node dependencies
npm install

# Install Rust toolchain (if missing)
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup toolchain install stable

# Install the Tauri CLI (globally optional, npx works too)
npm install -D @tauri-apps/cli
# or: cargo install tauri-cli

# Run the app in dev mode (starts PHP server and opens the Tauri window)
npm run start

# Build native bundles (requires platform-specific tools)
npm run build
