Ghost Node Frontend Migration Implementation Plan

For agentic workers: REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Replace dashboard.html with a Next.js + React + TypeScript + Tailwind frontend, tab-by-tab, while the Python backend runs untouched on port 8000.

Architecture: Next.js App Router frontend in frontend/ alongside existing files. All API calls proxy to FastAPI on port 8000 via Next.js rewrites. Built phase-by-phase — old dashboard.html stays live until Phase 7.

Tech Stack: Next.js 14, React 18, TypeScript, Tailwind CSS, shadcn/ui, Zustand, TanStack Query, Framer Motion, @dnd-kit, Lucide React, next/image, next/font, Vitest + React Testing Library

Spec: docs/superpowers/specs/2026-03-11-frontend-migration-design.md

Chunk 1: Phase 0 — Scaffold

Task 1: Prerequisites + Project Init

Files:

Create: frontend/package.json (via npx)
Create: frontend/next.config.ts
Create: frontend/tsconfig.json (via npx)
Step 1: Verify Node.js is installed

node --version
npm --version

Expected: Node 18+ and npm 9+. If not installed, download from nodejs.org.

Step 2: Create Next.js app

cd "C:/Users/Abbas/Documents/Downloads/ClaudeAuction2"
npx create-next-app@latest frontend --typescript --tailwind --eslint --app --no-src-dir --import-alias "@/*"

When prompted, accept all defaults.

Step 3: Install all additional dependencies

cd frontend
npm install zustand @tanstack/react-query framer-motion @dnd-kit/core @dnd-kit/sortable @dnd-kit/utilities lucide-react
npm install class-variance-authority clsx tailwind-merge
npm install @radix-ui/react-dialog @radix-ui/react-toast @radix-ui/react-slot

Step 4: Install dev/test dependencies

npm install -D vitest @vitejs/plugin-react @testing-library/react @testing-library/user-event @testing-library/jest-dom jsdom

Step 5: Add vitest config to package.json

Open frontend/package.json and add to the "scripts" section:

"test": "vitest",
"test:ui": "vitest --ui"

And add after "devDependencies":

,
"vitest": {
  "environment": "jsdom",
  "globals": true,
  "setupFiles": ["./vitest.setup.ts"]
}

Step 6: Create vitest setup file

Create frontend/vitest.setup.ts:

import '@testing-library/jest-dom'

Step 7: Commit

cd "C:/Users/Abbas/Documents/Downloads/ClaudeAuction2"
git add frontend/
git commit -m "feat: scaffold Next.js frontend project"

Task 2: Configure next.config.ts + Tailwind

Files:

Modify: frontend/next.config.ts
Modify: frontend/tailwind.config.ts
Modify: frontend/app/globals.css
Step 1: Write failing test for theme colors

Create frontend/__tests__/theme.test.ts:

import { describe, it, expect } from 'vitest'
import resolveConfig from 'tailwindcss/resolveConfig'
import tailwindConfig from '../tailwind.config'

const config = resolveConfig(tailwindConfig as any)

describe('Ghost Node theme', () => {
  it('has ghost accent color defined', () => {
    expect((config.theme.colors as any).ghost?.accent).toBe('#00ff88')
  })
  it('has ghost bg color defined', () => {
    expect((config.theme.colors as any).ghost?.bg).toBe('#0a0e17')
  })
})

Step 2: Run test — expect FAIL

cd frontend && npm test -- --run theme

Step 3: Replace frontend/next.config.ts

import type { NextConfig } from 'next'

const nextConfig: NextConfig = {
  async rewrites() {
    return [
      { source: '/api/:path*', destination: 'http://localhost:8000/api/:path*' },
    ]
  },
  images: {
    remotePatterns: [
      { protocol: 'https', hostname: '**' },
      { protocol: 'http', hostname: '**' },
    ],
  },
}

export default nextConfig

Step 4: Replace frontend/tailwind.config.ts

import type { Config } from 'tailwindcss'

const config: Config = {
  content: [
    './pages/**/*.{js,ts,jsx,tsx,mdx}',
    './components/**/*.{js,ts,jsx,tsx,mdx}',
    './app/**/*.{js,ts,jsx,tsx,mdx}',
  ],
  theme: {
    extend: {
      colors: {
        ghost: {
          bg:     '#0a0e17',
          panel:  '#111827',
          border: '#1f2937',
          accent: '#00ff88',
          gold:   '#fbbf24',
          danger: '#ef4444',
          dim:    '#6b7280',
          text:   '#e5e7eb',
        },
      },
      fontFamily: {
        sans: ['var(--font-inter)', 'sans-serif'],
        mono: ['var(--font-jetbrains)', 'monospace'],
      },
    },
  },
  plugins: [],
}

export default config

Step 5: Replace frontend/app/globals.css

@tailwind base;
@tailwind components;
@tailwind utilities;

/* Override shadcn/ui CSS variables to match Ghost Node cyberpunk palette */
:root {
  --background: 10 14 23;          /* ghost-bg */
  --foreground: 229 231 235;       /* ghost-text */
  --card: 17 24 39;               /* ghost-panel */
  --card-foreground: 229 231 235;
  --primary: 0 255 136;           /* ghost-accent */
  --primary-foreground: 10 14 23;
  --destructive: 239 68 68;       /* ghost-danger */
  --border: 31 41 55;             /* ghost-border */
  --muted: 107 114 128;           /* ghost-dim */
  --radius: 0.25rem;
}

* { box-sizing: border-box; }

body {
  background-color: #0a0e17;
  color: #e5e7eb;
  font-family: var(--font-inter), sans-serif;
}

/* Scrollbar styling — cyberpunk */
::-webkit-scrollbar { width: 6px; }
::-webkit-scrollbar-track { background: #111827; }
::-webkit-scrollbar-thumb { background: #1f2937; border-radius: 3px; }
::-webkit-scrollbar-thumb:hover { background: #00ff88; }

    @apply px-2 py-1 border border-ghost-danger text-ghost-danger font-mono text-xs hover:bg-ghost-danger hover:text-ghost-bg transition-colors;
  }
}

Step 9: Create frontend/app/listings/page.tsx

import ListingsTable from '@/components/listings/ListingsTable'

export default function ListingsPage() {
  return (
    <div className="space-y-3">
      <div>

      <ListingsTable />
    </div>
  )
}

Step 10: Run all tests

cd frontend && npm test -- --run

Step 11: Verify in browser

Open http://localhost:3000/listings. Expected: table with real listings from the backend, thumbnails, countdown ticking, detail panel slides in on title click.

Step 12: Commit

cd ..
git add frontend/
git commit -m "feat: Phase 2 complete — Listings tab with countdown, thumbnails, detail panel"

Step 4: Run all tests

Step 5: Verify all 6 tabs in browser

Open each tab and confirm: Dashboard (live stats), Listings (table + detail), Keywords (drag-drop), Sites (health + adapt), Settings (save works), AI Log (cards stream).

Chunk 5: Phase 7 — Production Serving

Task 13: Switch FastAPI to serve Next.js build

Files:

Modify: frontend/next.config.ts (add output: 'export')
Modify: worker.py (mount static files)
Modify: .claude/launch.json (add frontend dev server entry)
Step 1: Add output: 'export' to next.config.ts

Add output: 'export' to the nextConfig object in frontend/next.config.ts:

const nextConfig: NextConfig = {
  output: 'export',   // ← add this line
  async rewrites() { ... },
  images: { ... },
}

Note: output: 'export' disables the /api/stream SSE route and Next.js middleware in the static build. For the production build, the SSE will fall back to client-side polling (StatusBar degrades gracefully to setInterval calling FastAPI directly). Add this note as a comment.

Step 2: Build the Next.js app

cd frontend && npm run build

Expected: frontend/out/ directory created with static files. Zero build errors.

Step 3: Add StaticFiles mount to worker.py

Read worker.py first to find where the FastAPI app is defined and where routes are declared. Find the line app = FastAPI(...) near the top. Add the following at the END of the FastAPI route definitions (after all @app.get/@app.post decorators), before the thread startup code:

# ── Phase 7: Serve Next.js static build ─────────────────────────────────────
import pathlib as _pathlib
_frontend_out = _pathlib.Path(__file__).parent / "frontend" / "out"
if _frontend_out.exists():
    from fastapi.staticfiles import StaticFiles
    app.mount("/", StaticFiles(directory=str(_frontend_out), html=True), name="frontend")

The if _frontend_out.exists() guard means: if no build exists yet, FastAPI still serves dashboard.html as before. The migration is safe to deploy incrementally.

Step 4: Update .claude/launch.json to add frontend dev server

{
  "version": "0.0.1",
  "configurations": [
    {
      "name": "Ghost Node Backend",
      "runtimeExecutable": "python",
      "runtimeArgs": ["worker.py"],
      "port": 8000
    },
    {
      "name": "Ghost Node Frontend (dev)",
      "runtimeExecutable": "npm",
      "runtimeArgs": ["run", "dev", "--prefix", "frontend"],
      "port": 3000
    }
  ]
}

Step 5: Restart backend and verify production build

# Stop any running python worker.py, then restart:
cd "C:/Users/Abbas/Documents/Downloads/ClaudeAuction2"
python worker.py

Open http://localhost:8000. Expected: Ghost Node React dashboard served by FastAPI. All 6 tabs work. dashboard.html is no longer served at / — it still exists on disk but is superseded.

Step 6: Final test run

cd frontend && npm test -- --run

Expected: All tests pass.

Step 7: Final commit

cd "C:/Users/Abbas/Documents/Downloads/ClaudeAuction2"
git add frontend/next.config.ts worker.py .claude/launch.json
git commit -m "feat: Phase 7 complete — FastAPI serves Next.js static build, migration complete"

Summary

Phase	Tab	Key deliverable
0	Scaffold	Next.js project, Tailwind theme, SSE, layout shell
1	Dashboard	Live stats + activity log via Zustand + SSE
2	Listings	Table + countdown + thumbnails + detail panel
3	Keywords	Drag-drop + inline edit + batch import
4	Sites	Health badges + AI adapt + drag-drop
5	Settings	All 30+ config keys + backup/restore
6	AI Log	Live AI decision stream + filters
