Electron + React desktop focus tracker with a Vercel API that settles using Solana.

From repo root:

npm install
cd desktop && npm install

Copy .env.example to .env in repo root and fill in:

• SOLANA_RPC_URL – Solana RPC (e.g. https://api.devnet.solana.com)
• SOL_TREASURY_SECRET – full JSON array for a devnet wallet secret key
• MOCK_SOL_PRICE_USD – optional, default 100

Copy desktop/.env.example to desktop/.env:

• Local dev: VITE_BACKEND_URL=http://localhost:3000
• Production: VITE_BACKEND_URL=https://focusfee.vercel.app (or your Vercel URL)

From the project root, run:

npm run dev

This now starts:

• API server (port 3000)
• Electron desktop app (with Vite dev server)

If you want browser-only mode instead, run:

npm run dev:browser

Then open http://localhost:5173 in your browser.

Alternative (two terminals): Run npm run dev:api in one terminal, then npm run dev:web in another. Open http://localhost:5173.

If port 3000 is in use: $env:PORT=3001; npm run dev and the app will proxy to 3001.

Terminal 2 – Desktop app:

npm run dev:desktop

Ensure desktop/.env has VITE_BACKEND_URL=http://localhost:3000 for local API.

When ready to deploy the API:

npm run deploy

Or vercel for preview, vercel --prod for production.

Set env vars in Vercel dashboard (Settings → Environment Variables): SOLANA_RPC_URL, SOL_TREASURY_SECRET, MOCK_SOL_PRICE_USD.

Then update desktop/.env to use your Vercel URL for production builds.

From repo root:

npm run build:desktop

Settlement endpoint is:

POST /api/invest

Body:

{
	"usdCents": 125,
	"toAddress": "<solana-public-key>"
}
