wealth-alpha-chat

Drop-in React / Next.js chat widget for Wealth Alpha AI — chip-driven flows, JWT auth, 30-minute sliding session, full markdown rendering, AI free-text routing via /intent/detect + /ama/follow-up.

The library is one component (<WealthChat />) plus a backend chat router (chat_widget.py) that proxies your 20 telegram-api endpoints, persists every turn, and returns chip + message responses ready to render.

What you get

8 root chips matching the Telegram bot: Stock Analysis, Stock Discovery, New Listings, Portfolio Risk, Market Forecast, Crypto, Tradable Picks, Peer Comparison
Multi-step flows with chip + free-text inputs (symbol → date → price → result)
Drill-down chips on every list result — click a stock row to dive into its analysis
AI free-text — typed queries get classified by /intent/detect and routed to the right chip flow, with /ama/follow-up for ambiguous queries
30-minute sliding session stored in localStorage["wac_session"]
Auto-discovers JWT from localStorage["token"] (or access_token / auth_token / jwt) — no bridge code required in the host app
Auto-logout — when the host app removes its token (user signs out), the chat clears its session on next render and shows the AuthGate
Server-side history — every turn saved to chat_messages via the team's ChatService
Markdown rendering with markdown-it — bold, italic, bullets, links, code, headings

Quick install

npm install wealth-alpha-chat

In your app's root (e.g. src/app/layout.tsx for Next.js App Router):

import { WealthChat } from "wealth-alpha-chat";
import "wealth-alpha-chat/styles.css";

export default function RootLayout({ children }) {
  return (
    <html>
      <body>
        {children}
        <WealthChat
          apiBase={process.env.NEXT_PUBLIC_API_BASE ?? "http://localhost:8013/api/v1/chat-widget"}
          authCheck="/me"
          loginUrl="/login"
          sessionTTL={1800}
          brandName="Wealth Alpha AI"
          brandColor="#1a2d5a"
          position="bottom-right"
        />
      </body>
    </html>
  );
}

Your existing JWT login (stored under localStorage["token"]) is automatically picked up — no bridge component needed.

For the full integration walkthrough see docs/SETUP.md.
