Modern React frontend stack:

•Vite - Build tooling
•React 19 - UI framework
•TypeScript - Type safety
•Tailwind CSS v4 - Utility-first styling (@tailwindcss/vite plugin)
•shadcn/ui - Component library (New York style)
•React Router v7 - Client-side routing

Environment Setup

Use asdf to manage Node.js versions:

bash

# Install Node.js plugin (one-time)
asdf plugin add nodejs

# Set project Node.js version
asdf set nodejs latest:22

This creates a .tool-versions file in the project root that ensures consistent Node.js versions across the team.

Reference Files

File	When to Use
setup-guide.md	Starting a new project from scratch
patterns.md	Implementing features, understanding architecture
maplibre.md	Working with MapLibre GL JS maps

"flex items-center gap-4"           // Flexbox with gap
"bg-muted text-muted-foreground"    // Muted backgrounds
"border-b bg-background"            // Borders and backgrounds
"h-screen overflow-auto"            // Full height scrolling
"space-y-4"                         // Vertical spacing

Common Gotchas

•Package management: Use npm install <pkg> not manual package.json edits
•shadcn components: Use npx shadcn@latest add <component> -y
•React Router imports: Use react-router NOT react-router-dom
