Getting Started

Use Node.js 20, 22, 23, 24, or 25. Then install dependencies and run the development server:

npm install
npm run dev

Open http://localhost:3000 with your browser to see the result.

If you switch Node.js versions after installing dependencies, reinstall them so the native SQLite package is rebuilt for the active Node version:

npm install

Build

npm run build
npm run start

Data

Gradient data is stored in data/gradients.sqlite. The app also seeds default gradients from src/data/gradients-parsed.json when the database is empty.

Deploy on Vercel

The easiest way to deploy your Next.js app is to use the Vercel Platform from the creators of Next.js.

Check out our Next.js deployment documentation for more details.
