React Production Build

Build the Lessley frontend for production deployment.

Command

cd lessley-frontend && npm run build

What it does

1. Runs TypeScript type checking (tsc -b)
2. Bundles with Vite (Rolldown) into dist/
3. Code-splits lazy-loaded routes into separate chunks
4. Minifies and tree-shakes for smallest bundle size

Output

Production files are written to lessley-frontend/dist/:

• index.html — entry point
• assets/*.js — JavaScript chunks (one per lazy route + shared)
• assets/*.css — compiled Tailwind CSS
