🛠 Tech Stack

• Frontend: Next.js 14, TypeScript
• Styling: Tailwind CSS, shadcn/ui

Used Cursor as a pair-programmer for refactors and multi-file edits; all logic and integrations were implemented, reviewed, and tested by me. Initial UI was drafted with V0, then customized.

📝 Getting Started

1. Clone the repository
2. Install dependencies
3. Set up Supabase project
4. Configure environment variables
5. Run npm run dev

🚀 Quick Start

Setup

1. Install dependencies

 npm install

2. Environment

Create .env.local with Supabase credentials

NEXT_PUBLIC_SUPABASE_URL=your_supabase_project_url
NEXT_PUBLIC_SUPABASE_ANON_KEY=your_supabase_anon_key

Development

Run local development server

npm run dev

Scripts

npm run dev (start dev server)
npm run build (production build)
npm run start (run production build locally)

🔧 Troubleshooting

• 400 Bad Request on insert/update Make sure your Supabase table has all columns used by the app (color, pinned, etc.). The payload must match column names.

• “Could not find the 'color' column” Add the color text column (default 'default'), then redeploy/rerun.

• Cannot update/delete (RLS errors) In dev, use permissive policies (allow all). In prod, write proper auth-based policies.

• Pinned notes don’t move Ensure the client sorts: pinned first, then created_at desc. (This repo’s page.tsx already does it.)

Deploy on Vercel

1. Connect repository to Vercel
2. Add environment variables:
   • NEXT_PUBLIC_SUPABASE_URL
   • NEXT_PUBLIC_SUPABASE_ANON_KEY
