🚀 Development

Quick Start

# 1. Install dependencies
npm install

# 2. Option A: Dev Next.js only
npm run dev:web   # http://localhost:3000

# 3. Option B: Dev with Go
npm run build:dev # Build Next.js + sync to Go
npm run dev:go    # Run Go server

Workflow

Frontend Development (Next.js):

npm run dev:web   # Hot reload on :3000

Full Stack Development (Next.js + Go):

# Terminal 1: Build & sync on changes
npm run build:dev

# Terminal 2: Run Go server
npm run dev:go    # http://localhost:8080

After changing Next.js code:

npm run build:dev # Re-build and sync
# Go server will auto-serve new files
