Once UI monorepo

This monorepo hosts the official Once UI package and its internal development sandbox. It is designed for testing, development, and contribution—not for production deployment.

Developer notice

It includes:

• packages/core: the published @once-ui-system/core package
• apps/docs: the official documentation of Once UI and Magic templates built with Magic Docs
• apps/dev: a simple sandbox app wired via symlink for testing components

This setup is intended for contributors and maintainers. If you're building a real project, we recommend using:

1. Once UI Starter
2. or install via your package manager:

npm install @once-ui-system/core
# or
yarn add @once-ui-system/core
# or
pnpm add @once-ui-system/core

For contributors

Fork this repo, install dependencies, and run apps:

pnpm install
pnpm dev

The components will update automatically when you make changes to the Core library. If you modify the CSS modules, you'll have to run pnpm build in the packages/core directory.
