SolidJS + Vite Migration Complete

Summary

The Productier frontend has been successfully migrated from SolidStart to pure SolidJS + Vite. The application is now running correctly with all features intact.

What Was Changed

1. Vite Configuration (vite.config.ts)

• Updated the path resolution to use ES modules (fileURLToPath and dirname)
• Maintained the ~ alias for clean imports
• Kept the proxy configuration for the auth service

2. Package Configuration (package.json)

• Already configured correctly with:
  • solid-js for the framework
  • vite-plugin-solid for Vite integration
  • @solidjs/router for routing
  • No SolidStart dependencies

3. Application Structure

• Entry point: src/index.tsx - Uses solid-js/web render
• Main app: src/app.tsx - Pure SolidJS Router setup
• Routes: All routes in src/routes/ are standard SolidJS components
• No server-side rendering (SSR) - Pure client-side app

Running the Application

Development Mode

1. Start the backend services:

   docker compose up
   

2. Start the frontend dev server:

   cd apps/frontend
   npm run dev
   

3. Open http://localhost:5173

Production Build

cd apps/frontend
npm run build

The build output will be in apps/frontend/dist/
