SIDE-BY-SIDE CODE SAMPLES

# Project Instructions

## Stack
- React 19 with TypeScript
- Supabase for backend (auth, database, storage)
- TailwindCSS v4 + shadcn/ui components
- Vite for building

## Architecture
- Feature-based folder structure
- Each feature owns its components, hooks, and types
- Shared components in src/components/ui/
- All API calls go through src/lib/supabase.ts

## Conventions
- Use shadcn/ui components before creating custom ones
- Mobile-first responsive design
- Use Supabase RLS policies for authorization
- Prefer server-side filtering over client-side

## Brand
- Primary color: #6366F1 (indigo)
- Font: Inter for body, Cal Sans for headings
- Rounded corners (radius-lg) on all cards

Roo Code

.roo/rules/*.md

markdown

# Code Standards

## TypeScript
- Enable strict mode in all tsconfig files
- No `any` types — use `unknown` and narrow
- Prefer interfaces over type aliases for object shapes

## React
- Functional components only
- Use custom hooks for shared stateful logic
- Colocate component, styles, and tests

## Git
- Conventional commits (feat:, fix:, chore:, etc.)
- Keep commits atomic and focused
- Squash merge feature branches

KEY DIFFERENCES

1. IDE integration

Lovable: Platform. Roo Code: Supported.

WHICH SHOULD I USE?

Recommendation

Choose based on your IDE/CLI preference. If you use Lovable, configure AGENTS.md. If you use Roo Code, configure .roo/rules/*.md. Many projects include config files for multiple tools so each team member can use their preferred editor.
