Base Web React Components

Build status

Base is a design system comprised of modern, responsive, living components. Base Web is the React implementation of Base.


On npm, you can find Base Web as



and its peer dependencies to your project:
# using yarn
yarn add baseui styletron-react styletron-engine-atomic

using npm

npm install baseui styletron-react styletron-engine-atomic

import {Client as Styletron} from 'styletron-engine-atomic';
import {Provider as StyletronProvider} from 'styletron-react';
import {LightTheme, BaseProvider, styled} from 'baseui';
import {StatefulInput} from 'baseui/input';

const engine = new Styletron();

const Centered = styled('div', { display: 'flex', justifyContent: 'center', alignItems: 'center', height: '100%', });

export default function Hello () { return ( ); }

Both Base Web and Styletron come with flow types and TypeScript. All our components are typed and examples have Vanilla, Flow and TypeScript versions. For Styletron + TS, you need to add some additional packages:

yarn add @types/styletron-standard @types/styletron-react @types/styletron-engine-atomic
