Prerequisites

• Node.js 18 or newer

npm install

cd ..\frontend
npm install

Run The App

Use two terminals.

Terminal 1:

cd Phitien\backend
node src/server.js

Terminal 2:

cd Phitien\frontend
npm start

Then open http://localhost:3000.

AI Market Generator

Enter an Anthropic API key in the header, connect it, then type a topic in the generator form. Phitien will request new prediction markets grounded in current news and append them to the existing market list.

• Edit files in frontend/src and backend/src, not in frontend/build
• The build folder is generated output from npm run build
• Market and user data are stored in backend/src/data/*.json
