Migration Plan: Next.js to Vite + Electron + TanStack

Document Version: 1.1 Date: December 2025 Status: Phase 2 Complete - Core Migration Done Branch: refactor/frontend

Executive Summary
Current Architecture Assessment
Proposed New Architecture
Folder Structure
Shared Packages (libs/)
Type-Safe Electron Implementation
Components Refactoring
Web + Electron Dual Support
Migration Phases
Expected Benefits
Risk Mitigation

Executive Summary

Why Migrate?

Our current Next.js implementation uses less than 5% of the framework's capabilities. We're essentially running a static SPA with unnecessary overhead:

Next.js Feature	Our Usage
Server-Side Rendering	❌ Not used
Static Site Generation	❌ Not used
API Routes	⚠️ Only 2 test endpoints
Image Optimization	❌ Not used
Dynamic Routing	❌ Not used
App Router	⚠️ File structure only
Metadata API	⚠️ Title/description only
Static Export	✅ Used (`output: "export"`)

Migration Benefits

Metric	Current (Next.js)	Expected (Vite)
Dev server startup	~8-15s	~1-3s
HMR speed	~500ms-2s	~50-100ms
Production build	~45-90s	~15-30s
Bundle overhead	Next.js runtime	None
Type safety (Electron)	0%	100%
Debug capabilities	Limited	Full debug console

Target Stack

Bundler: Vite
Framework: React 19
Routing: TanStack Router (file-based)
Data Fetching: TanStack Query
State: Zustand (unchanged)
Styling: Tailwind CSS 4 (unchanged)
Desktop: Electron (TypeScript rewrite)

Current Electron Layer Issues

Issue	Impact	Solution
Pure JavaScript	No compile-time safety	Migrate to TypeScript
Untyped IPC handlers	Runtime errors	IPC Schema with generics
String literal channels	Typos cause silent failures	Const enums
No debug tooling	Hard to diagnose issues	Debug console feature
Monolithic main.js	Hard to maintain	Modular IPC organization

Current Component Structure Issues

View File	Lines	Issue
spec-view.tsx	1,230	Exceeds 500-line threshold
analysis-view.tsx	1,134	Exceeds 500-line threshold
agent-view.tsx	916	Exceeds 500-line threshold
welcome-view.tsx	815	Exceeds 500-line threshold
context-view.tsx	735	Exceeds 500-line threshold
terminal-view.tsx	697	Exceeds 500-line threshold
interview-view.tsx	637	Exceeds 500-line threshold
board-view.tsx	685	✅ Already has subfolder structure

Immediate Dialog Reorganization

# Settings-view: Move dialogs to proper location
mv settings-view/components/keyboard-map-dialog.tsx → settings-view/dialogs/
mv settings-view/components/delete-project-dialog.tsx → settings-view/dialogs/

# Root components: Organize global dialogs
mv components/dialogs/board-background-modal.tsx → board-view/dialogs/

Web + Electron Dual Support

Platform Detection

// src/lib/platform.ts
export const isElectron = typeof window !== 'undefined' && 'electronAPI' in window;

export const platform = {
  isElectron,
  isWeb: !isElectron,
  isMac: isElectron ? window.electronAPI.platform === 'darwin' : false,
  isWindows: isElectron ? window.electronAPI.platform === 'win32' : false,
  isLinux: isElectron ? window.electronAPI.platform === 'linux' : false,
};

API Abstraction Layer

// src/lib/api/file-picker.ts
import { platform } from '../platform';

export interface FilePickerResult {
  canceled: boolean;
  paths: string[];
}

export async function pickDirectory(): Promise<FilePickerResult> {
  if (platform.isElectron) {
    const result = await window.dialogAPI.openDirectory();
    return { canceled: result.canceled, paths: result.filePaths || [] };
  }

  // Web fallback using File System Access API
  try {
    const handle = await window.showDirectoryPicker();
    return { canceled: false, paths: [handle.name] };
  } catch (error) {
    if ((error as Error).name === 'AbortError') {
      return { canceled: true, paths: [] };
    }
    throw error;
  }
}

export async function pickFile(options?: {
  accept?: Record<string, string[]>;
}): Promise<FilePickerResult> {
  if (platform.isElectron) {
    const result = await window.dialogAPI.openFile({
      filters: options?.accept
        ? Object.entries(options.accept).map(([name, extensions]) => ({
            name,
            extensions,
          }))
        : undefined,
    });
    return { canceled: result.canceled, paths: result.filePaths || [] };
  }

  // Web fallback
  try {
    const [handle] = await window.showOpenFilePicker({
      types: options?.accept
        ? Object.entries(options.accept).map(([description, accept]) => ({
            description,
            accept: { 'application/*': accept },
          }))
        : undefined,
    });
    return { canceled: false, paths: [handle.name] };
  } catch (error) {
    if ((error as Error).name === 'AbortError') {
      return { canceled: true, paths: [] };
    }
    throw error;
  }
}

Migration Phases

Phase 1: Foundation (Week 1-2)

Goal: Set up new build infrastructure without breaking existing functionality.

Create vite.config.mts with electron plugins
Create electron/tsconfig.json for Electron TypeScript
Convert electron/main.js → electron/main.ts
Convert electron/preload.js → electron/preload.ts
Implement IPC schema and type-safe handlers (deferred - using existing HTTP API)
Set up TanStack Router configuration
Port debug console from starter template (deferred)
Create index.html for Vite entry

Deliverables:

Working Vite dev server
TypeScript Electron main process
Debug console functional (deferred)

Phase 2: Core Migration (Week 3-4)

Goal: Replace Next.js with Vite while maintaining feature parity.

Create src/renderer.tsx entry point
Create src/App.tsx root component
Set up TanStack Router with file-based routes
Port all views to route files
Update environment variables (NEXT_PUBLIC_* → VITE_*)
Verify Zustand stores work unchanged
Verify HTTP API client works unchanged
Test Electron build
Test Web build (needs verification)

Additional completed tasks:

Remove all "use client" directives (not needed in Vite)
Replace all setCurrentView() calls with TanStack Router navigate()
Rename apps/app to apps/ui
Update package.json scripts
Configure memory history for Electron (no URL bar)
Fix ES module imports (replace require() with import)
Remove PostCSS config (using @tailwindcss/vite plugin)

Deliverables:

All views accessible via TanStack Router
Electron build functional
Web build functional (needs testing)
No regression in existing functionality

Phase 3: Component Refactoring (Week 5-7)

Goal: Refactor large view files to follow folder-pattern.md.

Refactor spec-view.tsx (1,230 lines)
Refactor analysis-view.tsx (1,134 lines)
Refactor agent-view.tsx (916 lines)
Refactor welcome-view.tsx (815 lines)
Refactor context-view.tsx (735 lines)
Refactor terminal-view.tsx (697 lines)
Refactor interview-view.tsx (637 lines)
Reorganize settings-view dialogs

Deliverables:

All views under 500 lines
Consistent folder structure across all views
Barrel exports for all component folders

Phase 4: Package Extraction (Week 8)

Goal: Create shared packages for better modularity.

Create libs/types/ package
Create libs/utils/ package
Create libs/platform/ package
Create libs/model-resolver/ package
Create libs/ipc-types/ package
Update imports across apps

Deliverables:

5 new shared packages
No code duplication between apps
Clean dependency graph

Phase 5: Polish & Testing (Week 9-10)

Goal: Ensure production readiness.

Write E2E tests with Playwright
Performance benchmarking
Bundle size optimization
Documentation updates
CI/CD pipeline updates
Remove Next.js dependencies

Deliverables:

Comprehensive test coverage
Performance metrics documentation
Updated CI/CD configuration
Clean package.json (no Next.js)

Expected Benefits

Developer Experience

Aspect	Before	After
Dev server startup	8-15 seconds	1-3 seconds
Hot Module Replacement	500ms-2s	50-100ms
TypeScript in Electron	Not supported	Full support
Debug tooling	Limited	Full debug console
Build times	45-90 seconds	15-30 seconds

Code Quality

Aspect	Before	After
Electron type safety	0%	100%
Component organization	Inconsistent	Standardized
Code sharing	None	5 shared packages
Path handling	Ad-hoc	Centralized utilities

Bundle Size

Aspect	Before	After
Next.js runtime	~200KB	0KB
Framework overhead	High	Minimal
Tree shaking	Limited	Full

Risk Mitigation

Rollback Strategy

Branch-based development: All work on feature branch
Parallel running: Keep Next.js functional until migration complete
Feature flags: Toggle between old/new implementations
Comprehensive testing: E2E tests before/after comparison

Known Challenges

Challenge	Mitigation
Route migration	TanStack Router has similar file-based routing
Environment variables	Simple search/replace (`NEXT_PUBLIC_` → `VITE_`)
Build configuration	Reference electron-starter-template
SSR considerations	N/A - we don't use SSR

Testing Strategy

Unit tests: Vitest for component/utility testing
Integration tests: Test IPC communication
E2E tests: Playwright for full application testing
Manual testing: QA checklist for each view
