Live Example

Tl;dr

You don't know CSS Flexbox? Read here!

2 components:

• <Flex />
  • creates a flex container.
  • provides EVERY Flexbox property.
• <FlexItem />
  • creates a flexed item.
  • provides Flexbox properties for items only.

3 ways to set properties:

• flags (row, start, stretch, ecc...)
• classic properties (display, flexDirection, justifyContent, ecc...)
• short version of classic properties (justify, align, self, ecc...)

Install

# Install via NPM
npm i react-flex-element
# or Yarn
yarn add react-flex-element

Usage

Every Flexbox property can be set via one or more dedicated props.

Flexible "container" props

This first set of props refers to "flex container" related properties. For this reason they are only available for the component Flex.

display

<>
  <Flex /> // flex
  <Flex inline /> // inline-flex
  <Flex display="inline-flex" /> // inline-flex
</>

flex-direction

<>
  <Flex row /> // row
  <Flex col /> // column
  <Flex column /> // column

  <Flex colReverse /> // column-reverse
  <Flex columnReverse /> // column-reverse

  <Flex direction="column-reverse" /> // column-reverse
  <Flex flexDirection="column-reverse" /> // column-reverse
</>

The additional reverse prop can be used to programmatically revert the specified direction:

<>
  <Flex row reverse /> // row-reverse
  <Flex row reverse={true} /> // row-reverse
  <Flex row reverse={false} /> // row
</>

  <Flex flexWrap="wrap-reverse" /> // wrap-reverse
</>

justify-content

  <Flex start /> // flex-start
  <Flex end /> // flex-end
  <Flex center /> // center
  <Flex spaceBetween /> // space-between
  <Flex spaceAround /> // space-around

</>

align-items

</>

  <Flex rowGap={10} /> // 10px
  <Flex rowGap="10px" /> // 10px
</>

column-gap

<>
  <Flex colGap={10} /> // 10px
  <Flex colGap="10px" /> // 10px
  <Flex columnGap={10} /> // 10px

</>

gap

  <Flex gap={10} /> // 10px
  <Flex gap="10px" /> // 10px

  <Flex gap={[10, 20]} /> // 10px 20px
  <Flex gap="10px 20px" /> // 10px 20px
</>

Flexible "item" props

The set of props below refers to "flex items" related properties. They are all available for both Flex and FlexItem components.

order

<>
  <Flex order={3} /> // 3
  <Flex order="3" /> // 3
</>

flex-grow

<>
  <Flex grow /> // 1
  <Flex grow={true} /> // 1
  <Flex grow={false} /> // 0
  <Flex grow={3} /> // 3
  <Flex grow="3" /> // 3
  <Flex flexGrow={3} /> // 3
  <Flex flexGrow="3" /> // 3
</>

flex-shrink

<>
  <Flex shrink /> // 1
  <Flex shrink={true} /> // 1
  <Flex shrink={false} /> // 0
  <Flex shrink={3} /> // 3
  <Flex shrink="3" /> // 3
  <Flex flexShrink={3} /> // 3
  <Flex flexShrink="3" /> // 3
</>

flex-basis

<>
  <Flex basis={10} /> // 10px

  <Flex selfEnd /> // flex-end
  <Flex selfCenter /> // center
  <Flex selfStretch /> // stretch
  <Flex selfBaseline /> // baseline
  
  <Flex self="flex-end" /> // flex-end
  <Flex alignSelf="flex-end" /> // flex-end
<>

width and height

<>
  <Flex fill /> // 100% width and height
  <Flex fill="x" /> // 100% width
  <Flex fill="y" /> // 100% height
  <Flex fill="page" /> // 100vw width and 100vh height
  <Flex fill="page-x" /> // 100vw width
  <Flex fill="page-y" /> // 100vh height
<>

Other props

By default, both Flex and FlexItem components renders a div element with the specified flex properties.

Nevertheless, it is possible to change this behaviour via the as prop:

Examples:

<>
  <Flex as="input" />
  <Flex as={MyCustomComp} />
</>

In addition, any additional prop passed to Flex or FlexItem will be drilled down to the render element or component.

Basic usage

<FlexItem id="myDiv" class="some-class" selfEnd grow={3} />

Usage with a different element

<FlexItem as="a" href="#foo" onClick={handleClick} grow />

Usage with a custom component

const MyComp = ({ size }) => (
  <span style={{ fontSize: size }}>
    {children}
  </span>
)

return (
  <FlexItem as={MyComp} size={18} selfEnd />
)

Components

Flex

Use it to create a flexible container.

<Flex>Hello world!</Flex>

By default, it renders a div element with the following CSS properties set:

display: flex;
align-items: center;

It provides all the properties listed above.

FlexItem

Use it to create a flexible item.

// React
<FlexItem>Hello world!</FlexItem>

By default, it renders a div element, but it does not set any CSS property.

Lastly, it provides only props related to order, flex-grow, flex-shrink, flex-basis and align-self properties.
