🚀 Quick Start

Prerequisites

• Node.js 18+
• Go 1.21+

Installation

# 1. Install dependencies
npm install

# 2. Option A: Dev Next.js only (with hot reload)
npm run dev:web   # http://localhost:3000

# 3. Option B: Full stack with Go
npm run build:dev # Build Next.js + sync to Go
npm run dev:go    # Run Go server → http://localhost:8080

💻 Development

Frontend Development (Next.js)

npm run dev:web   # Hot reload on port 3000

Full Stack Development (Next.js + Go)

Terminal 1: Build & sync when you change Next.js code

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 (no restart needed)

🔨 Build

Development Build (Quick)

npm run build:dev
# → Builds Next.js + syncs to Go static folder

Production Binary

npm run build
# → Builds Next.js + Go binary
# → Output: dist/nekoflow (single binary ~10-30MB)

Available Commands

Command	Description
npm run dev:web	Dev Next.js only (port 3000, hot reload)
npm run dev:go	Run Go server (port 8080)
npm run build:web	Build Next.js static export
npm run sync:static	Copy Next.js build → Go static folder
npm run build:dev	Build + sync (for development)
npm run build	Full production build (creates binary)

🎯 Deploy

Simple Deployment

# Just copy and run the binary
./dist/nekoflow

# Or specify port
PORT=8080 ./dist/nekoflow

Deploy to Linux Server

# 1. Build for Linux
npm run build

# 2. Upload
scp dist/nekoflow-linux user@server:/opt/nekoflow

# 3. Run on server
ssh user@server
chmod +x /opt/nekoflow
./nekoflow

Docker (Optional)

FROM scratch
COPY dist/nekoflow /nekoflow
ENTRYPOINT ["/nekoflow"]

Tech Stack

Frontend:

• Next.js 14 (Static Export)
• React 18
• TypeScript
• Tailwind CSS

Backend:

• Go 1.21+
• gorilla/mux (Router)
• embed (Static files)

Build:

• npm workspaces
• Bash scripts
• Go build

❓ FAQ

Is this SSR (Server-Side Rendering)?

No. This uses Next.js Static Export (SSG - Static Site Generation).

• Next.js pre-renders pages to HTML at build time
• Go only serves static files (HTML/CSS/JS)
• React hydrates on the client-side
• API calls happen client-side via fetch()

Can I use getServerSideProps?

No. Static Export doesn't support:

• getServerSideProps()
• getServerData()
• ISR (Incremental Static Regeneration)

Use 'use client' with useEffect() and fetch() instead.

Why Go + Next.js?

• ✅ Single binary - Easy deployment
• ✅ No Node.js runtime needed in production
• ✅ Performance - Go is fast and lightweight
• ✅ Modern DX - React + TypeScript + Tailwind
• ✅ Cross-platform - Compile for Linux/Mac/Windows

Binary size?

Typically 10-30MB depending on:

• Go code size
• Next.js bundle size
• Static assets (images, fonts)
