What is it?

Blueprint is a React component toolkit for the web, aimed at complex, data-dense interfaces such as desktop-style applications that run in modern browsers. It is explicitly not a mobile-first toolkit.

The repository is a monorepo published as several npm packages. The core package provides styles and components, with companion packages for date and time inputs, icons (available as both SVG and icon font), item selection from lists, and a scalable, interactive spreadsheet-like table component. A colors package exposes the design system's color variables.

The project also includes documentation and demo applications, plus shared build tooling such as ESLint and stylelint plugins that enforce Blueprint usage conventions, and Sass and Webpack build scripts.
