react-flex-lite

Information

Package	react-flex-lite
Description	Flexbox components for React, as minimal as possible

Install

$ npm install react-flex-lite --save

Design

Heavily inspired by reflexbox and rebass.

This module aims to provide a very lightweight set of components on top of flexbox CSS and layout, and a higher order component to add this functionality to your own components. It does not handle breakpoints, media query listeners, or any other elements of responsive design. For that functionality, you should combine with a library like react-responsive.

Example Usage

Primary Components

import { Box, Flex } from 'react-flex-lite'

const Example = () => (
  <Flex column auto>
    <Flex shrink={0}>
      <Box>1</Box>
      <Box>2</Box>
      <Box>3</Box>
    </Flex>
    <Flex shrink={0}>
      <Box>1</Box>
      <Box>2</Box>
      <Box>3</Box>
    </Flex>
  </Flex>
)

Shorthand Components

For code clarity, VBox is a shorthand alias around <Flex column> and HBox is an alias for <Flex />

import { HBox, VBox } from 'react-flex-lite'

const Example = () => (
  <VBox auto>
    <Flex shrink={0}>
      <Box>1</Box>
      <Box>2</Box>
      <Box>3</Box>
    </HBox>
    <HBox shrink={0}>
      <Box>1</Box>
      <Box>2</Box>
      <Box>3</Box>
    </HBox>
  </VBox>
)

HOC

import { Layout } from 'react-flex-lite'

@Layout()
const Example = () => <div>Test</div>

Providing your own grid

By default, this library comes with an 8px grid configuration:

{
  "space": [0, 8, 16, 32, 64]
}

To provide your own configuration, you can provide it via context:

import { LayoutContext } from 'react-flex-lite'

const config = {
  space: [0, 10, 20, 30, 40]
}

// in the root of your app
<LayoutContext.Provider value={config}>
  <YourApplication />
</LayoutContext.Provider>
