Reflexy

Reflexy is react components library for flexbox and responsive layouts:

• Flex - flexbox layout with paddings and margins support.

• styled/Flex - styled version of Flex powered by @mui.

• styled/StyledReflexyWebpackPlugin - webpack plugin for replace regular imports of Flex with styled/Flex. Just import Flex like import { Flex, FlexWithRef } from 'reflexy'; or import { ResponsiveFlex } from 'reflexy/responsive'; and styled/Flex will be used instead.

• FlexWithRef - Flex with forwarded ref.

• TweakableElementWrapper - Wrapper for react element in order to use it with component prop of Flex.

• responsive/Responsive - container with breakpoints.

• responsive/ResponsiveRender - conditional render by breakpoints.

• responsive/ResponsiveFlex - Like Flex but with breakpoints.

• responsive/useMediaQuery - React hook for media queries.

• responsive/MediaQuery - utils for work with media queries and breakpoints.

Custom media queries

Used in CSS.

Name	Value
--xxs	only screen and (max-width: 479px)
--xs	only screen and (min-width: 480px) and (max-width: 767px)
--s	only screen and (min-width: 768px) and (max-width: 991px)
--m	only screen and (min-width: 992px) and (max-width: 1279px)
--l	only screen and (min-width: 1280px) and (max-width: 1919px)
--xl	only screen and (min-width: 1920px) and (max-width: 2559px)
--xxl	only screen and (min-width: 2560px)

Custom media queries can be used with postcss-custom-media. Example of configuration with preset-env:

const exportMediaQueries = require('reflexy/responsive/exportMediaQueries');

module.exports = {
  plugins: {
    'postcss-preset-env': {
      features: {
        'custom-media-queries': {
          importFrom: [{ customMedia: exportMediaQueries() }],
        },
      },
    },
  },
};

Installation

yarn add react reflexy
# or
npm install --save react reflexy

If you use styled version you should also install @mui packages.

Reflexy has own css files so you need provide loader for css files placed in node_modules folder (only if you do not use styled version). With webpack it could be css-loader:

{
  test: /\.css$/,
  include: path.join(__dirname, 'node_modules'),
  // or
  include: /reflexy/,
  use: [
    // ...
    { loader: 'css-loader', options: { modules: true } }, // enabled css-modules is necessary
    // ...
  ],
},

Flex

Usage

import { Flex, TweakableElementWrapper } from 'reflexy';

<Flex row justifyContent="center">
  ...
</Flex>

<Flex row justifyContent="center" component={TweakableElementWrapper} element={<button />}>
  ...
</Flex>

<Flex row justifyContent="center" component="button" onClick={...}>
  ...
</Flex>

<Flex row justifyContent="center" componentRef={componentRef}>
  ...
</Flex>

<Flex row justifyContent="center" component={CustomComponent} componentProp1={...} componentProp2={...}>
  ...
</Flex>

<Flex ml pb>
  ...
</Flex>;
