Strelka Components

React.js components and storybook for Strelka projects

Requirements

• Node.js
• Yarn package manager

Usage

$ yarn add emotion react-emotion emotion-theming recompose defaults.css @strelka/components

import 'defaults.css'
import { StrelkaThemeProvider, Container, Grid } from '@strelka/components'

const Page = () => (
  <StrelkaThemeProvider>
    <Container>
      <Grid>
        <Grid.Cell col={6}> Strelka </Grid.Cell>
      </Grid>
    </Container>
  </StrelkaThemeProvider>
)

Styling Props

Styling props are a special type of props that are used to style components. For example:

import { StrelkaThemeProvider, Div } from '@strelka/components'
  
const Example = () => (
  <StrelkaThemeProvider>
    <Div tm='inverted' pd mgM={2} hideT wd={1/3}>
      Example content
    </Div>
  </StrelkaThemeProvider>
)

Here pd, mgM, tm, hideT, wd are styling props that define, correspondingly, paddings, margins, colors, display and width on different screen sizes. M, T, D are styling props' modifiers for quickly setting styles for specific media query.

• M: (max-width: 768px)
• T: (min-width: 769px) and (max-width: 1024px)
• D: (min-width: 1025px)

Usage

Append to styled prop, then define value: pdM, mgD, hideM.

<StrelkaThemeProvider>
  <Div wdT={1/3} pdT hideM mgM={2} />
</StrelkaThemeProvider>
