⛽️ Usage

Development

Start both the proxy server and the frontend dev server:

# Terminal 1: Start the Go proxy server
cd proxy
go run main.go

# Terminal 2: Start the frontend dev server
cd app
npm run dev

Open your browser and navigate to http://localhost:5173

Production Build

export VITE_GO_MOD_PROXY_URL=xxxx
export ALLOWED_ORIGINS=yyyy
export PORT=8080

# Build the frontend
cd app
npm run build

# Build the Go proxy server
cd ../proxy
go build -o go-mod-graph-proxy main.go

The built frontend files will be in app/dist/. The proxy server can serve these files directly.
