    Indoqa Style-System

    This project provides an extensible style system for React with Typescript typed theme support and several base components following the principle of style as function of state:

    • Base components as building blocks which are integrated with theming:

      • <Box> (docs)
      • <Flex> (docs)
      • <Text> (docs)
      • <Grid>, <Row>, <Panel>, <ColRow>, <Col> (docs)
    • Typed components with Typescript

      typesafe properties

    • A typed base theme with sensible defaults (e.g. font styles based on system fonts)

    • Base CSS stylesheets (Bootstrap Reboot 4.1 and normalize.css are currently supported)

    Installation and usage

    yarn install @indoqa/style-system


    Setup the application theme based on the BaseTheme provided by Indoqa Style-System:

    import {BaseColors, BaseFontSizes, baseTheme, BaseTheme, typeScale} from '@indoqa/style-system'
    interface FontSizes extends BaseFontSizes {
      readonly extraBig: number | string,
    interface Colors extends BaseColors {
      readonly primary: string,
      readonly primaryDark: string,
      readonly primaryLight: string,
      readonly accent: string,
      readonly textSecondary: string
      readonly divider: string,
    interface Layout {
      readonly actionBarHeight: number,
      readonly menuWidth: number,
    export interface Theme extends BaseTheme {
      readonly fontSizes: FontSizes,
      readonly colors: Colors,
      readonly layout: Layout,
    const baseColors = {
      black_1: '#000000',
      black_2: '#120012',
      grey_1: '#727272',
      grey_2: '#BDBDBD',
      white_3: '#d5d5d5',
      white_1: '#ffffff',
      blue_1: '#c5cae9',
      blue_2: '#3f51b5',
      blue_3: '#303f9f',
      orange_1: '#ff5722',
    const baseFontSizes: FontSizes = {
      text: typeScale(1),
      big: typeScale(2),
      veryBig: typeScale(3),
      extraBig: typeScale(3),
      small: typeScale(0),
      verySmall: typeScale(-1),
    const theme: Theme = {
      breakpoints: baseTheme.breakpoints,
      colors: {
        primary: baseColors.blue_2,
        primaryDark: baseColors.blue_3,
        primaryLight: baseColors.blue_1,
        accent: baseColors.orange_1,
        text: baseColors.black_2,
        textSecondary: baseColors.grey_1,
        divider: baseColors.white_1,
      fontSizes: baseFontSizes,
      fontStyles: baseTheme.fontStyles,
      layout: {
        actionBarHeight: 50,
        menuWidth: 300,
      spacing: baseTheme.spacing,
      zIndexes: baseTheme.zIndexes,
    export default theme
    • The interface Theme extends the interface BaseTheme. This is important because all provided components are based on BaseTheme or extensions of it.
    • The implementation theme uses baseTheme properties or overrides them.

    Fela setup

    import {BaseCssProps, createFelaConfig, renderRebootCss} from '@indoqa/style-system'
    import {createRenderer} from 'fela'
    const felaConfig = createFelaConfig()
    const renderer = createRenderer(felaConfig)
    const baseCssProps: BaseCssProps = ...
    const App: React.FC = () => {
      React.useLayoutEffect(() => {
        renderRebootCss(renderer, baseCssProps)
      }, [])
      return (
        <RendererProvider renderer={renderer}>
          <Router history={history}>
            <ThemeProvider theme={theme}>
                <Route path="/" component={StyleSystemUIExplorer}/>
    export default App
    • renderRebootCss provides basic CSS styles based on the theme
    • provide a RendererProvider (all React components can get access to the Fela renderer)
    • provide a ThemeProvider (all React components can get access to the application theme)
    • createFelaConfig configures Fela with all the plugins which are usually required for web applications. It also registers named keys for breakpoints and print styles which are aligned with the PStyle type.
