CoachSync

CoachSync is a web-based platform that helps coaches manage their teams and monitor athlete performance by integrating wearable data, team communication, and streamlined team organization tools.

🚀 Goal

The main goal of CoachSync is to provide coaches with a centralized dashboard where they can:

• Create and manage multiple athlete teams
• Invite athletes to join their teams with a simple email signup
• View athlete health and activity data by integrating wearable devices (starting with Fitbit)
• Send team-wide announcements via a one-way chat
• View consolidated performance data in a team dashboard

The MVP focuses on coaches as the primary users, with athletes joining teams via invite links and connecting their wearable devices.

🛠️ Tech Stack

• Frontend: Next.js (React-based framework)
• Styling: Tailwind CSS, shadcn/ui
• Authentication & Backend: Supabase (PostgreSQL, Auth, Realtime)
• Wearable Integration: Fitbit Web API
• Deployment: Vercel (frontend), Supabase (backend)
• Charting: Chart.js or Recharts for data visualization
• Validation: Zod for schema-based client/server validation

✅ MVP Features

1. Team Management

   • Coaches can create and delete teams
   • Athletes can join via invite links

2. Authentication

   • Simple email and password-based signup (via Supabase Auth)
   • Centralized validation using Zod for both client and server

3. Fitbit Integration

   • Athletes can connect their Fitbit to sync basic health metrics (steps, heart rate, etc.)

4. Team Dashboard

   • Coaches can view consolidated data of their team members

5. Broadcast Chat

   • Coaches can send one-way messages to their teams (announcement feed)

📦 Folder Structure (Planned)

/pages          # Next.js pages (routes)
/components     # Shared React components
/lib            # Utility functions (e.g. API helpers, Fitbit logic, Zod schemas)
/styles         # Tailwind and global CSS
/supabase       # Supabase-related setup
/public         # Static assets

💻 Local Setup

# Install dependencies
npm install

# Run the dev server
npm run dev

You must configure Supabase project keys and Fitbit API credentials to enable full functionality. See .env.example for required keys.

👥 Team Roles

This project is being built by a 3-person team, each contributing across backend, frontend, and design. Roles are shared and rotated weekly.

📈 Upcoming Features

• Athlete wearable data sync (via Fitbit API)
• Coach notifications and updates feed
• Team-level data visualization (steps, HR, trends)
• Invite system for athletes (via secure link/token)

📌 Notes

• MVP is developed following Lean Startup principles and MoSCoW prioritization
• Initial Fitbit integration will use basic health metrics and expand over time
• Zod is used for all authentication-related validation (see /lib/validations/auth.ts)
