Fragmented notification checking across multiple social platforms

Build the frontend as a React SPA using Vite for fast HMR, styled with Tailwind CSS. Use Redux Toolkit for state management of OAuth tokens and notification payloads. The dashboard calls a Node.js backend (Express) that hosts a Fastify‑compatible OAuth proxy for each platform (Twitter API v2, Instagram Graph API, Reddit OAuth, LinkedIn API). Store tokens encrypted with libsodium in a PostgreSQL database accessed via Prisma ORM. For each platform, schedule a cron job with node‑cron that calls the respective "unread notifications" endpoint (e.g., GET /2/users/:id/mentions, /me/notifications) and normalizes results into a common schema stored in a DuckDB file for fast in‑memory queries. Expose a GraphQL endpoint (Apollo Server) that the React client queries for aggregated alerts, supporting filter arguments (platform, type). The browser extension is built with Manifest V3, using a background service worker that subscribes to the backend's SSE endpoint for real‑time push. When focus mode is toggled, the extension injects a content‑script that registers a webRequest.onBeforeRequest listener to block URLs matching user‑defined patterns, displaying a modal that links back to the dashboard. Communication between extension and backend uses the Fetch API with JWT‑signed requests. Deploy backend on Railway or Fly.io, using Docker with multi‑stage builds, and host the extension on Chrome Web Store.

The tool consolidates disparate notification streams into a single, queryable feed, eliminating repetitive API calls from the client and reducing bandwidth. By gating access to distracting sites until alerts are acknowledged, it cuts idle browsing time and lowers cognitive load. Server‑side normalization and DuckDB caching keep response latency sub‑200 ms, while the extension's blocking logic runs entirely client‑side, preserving privacy and avoiding extra server compute. Overall, it streamlines the daily check‑in routine, prevents missed critical alerts, and enforces disciplined focus without costly enterprise licenses.
