Connect JavaScript to Frontend

I need someone to help me connect the JavaScript side to this frontend that I was able to get through the aid of Replit AI. The Front end was built using Replit AI, and now I need assistance with integrating the JavaScript to ensure smooth functionality. The Front end was built using Replit AI and the languages used are •⁠ ⁠Frontend Framework: React (using TypeScript .tsx for UI components) •⁠ ⁠⁠Backend Runtime: Node.js (using modern JavaScript .mjs) •⁠ ⁠⁠Build System: Vite & TypeScript compiler •⁠ ⁠⁠Data Layer: OpenAPI / Zod (indicated by the api-spec and api-zod folders for handling automated network requests) So, basically - this project is an arbitrage and I want someone to help me link the javascript code and the frontend that I will be providing.
