🏎️ 💥 Microinteractions for React using micron.js

Microinteractions for React using micron.js.

WARNING: This package is deprecated and no longer maintained.

From Ondřej Dostál:

Microinteractions are single interactive moments in a product that enhance the workflow and increase ease of use.

Typically this is by way of subtle visual effects that are triggered to provide user feedback.

This can be done for a variety of reasons:

  • To provide feedback before triggering an action
  • To draw a users attention to a particular element
  • To hint that an action was successful
  • To indicate that an action failed
  • To make applications feel more responsive and rewarding to use.

react-micron helps achieve this by providing easy-to-use components which correspond to micro-actions that can be easily triggered by a user-interaction.

Yarn

yarn add react-micron

npm

npm install react-micron
import React from 'react'
import { Bounce } from 'react-micron'
 
const App = () => (
  <Bounce>
    <button>Click me!</button>
  </Bounce>
)
 
export default App

Simply add the component to the React application using JSX.

The following example shows the default props set explicitly.

import React from 'react'
import { Blink,
         Bounce,
         Fade,
         Flicker,
         Groove,
         Jelly,
         Jerk,
         Pop,
         Shake,
         Squeeze,
         Swing,
         Tada } from 'react-micron'
 
const App = () => (
  <Bounce
    events="onClick"
    timing="ease-in-out"
    duration={0.45}
    inline={false}
  >
    <button>Click me!</button>
  </Bounce>
)
 
export default App

Props

Children

The elements to bind the microinteraction to.

In most cases this should be regular children elements passed as a React node.

However it can also be a render prop which can accept up to 2 arguments:

  • interaction: Function which invokes the microinteraction.
  • micron: Method to access the micron API directly.

Events

events indicates what event handlers are used to trigger the microinteraction. Default: onClick

This can be a string or an array of strings to call the microinteraction on multiple events.

To disable any implicit event handling by react-micron, an empty array or object can be passed.

Alternatively, an object can be passed to explicitly set each event handler using curried functions.

An example of this is as follows:

{
  onClick: (interaction, micron) => () => interaction(),
  onMouseOver: (interaction, micron) => event => {
    console.log(event)
    micron().interaction('bounce').duration(2).timing('linear')
  }
}

By using a curried function the original arguments from the event handler can be used, along with the injected react-micron functions.

Timing

timing controls the easing of the microinteraction. Default: ease-in-out

Must be one of linear, ease-in, ease-out or ease-in-out.

Duration

duration is the duration in seconds of the microinteraction. Default: 0.45

Inline

inline controls what element the microinteraction is enclosed in. Default: false

If set a span is used to wrap the elements. Otherwise a div is used.

Advanced Usage

For more complex usage, using a render prop is recommended.

This allows the interaction to be triggered manually, and the micron API to be accessed directly.

import React from 'react'
import { Blink,
         Bounce,
         Fade,
         Flicker,
         Groove,
         Jelly,
         Jerk,
         Pop,
         Shake,
         Squeeze,
         Swing,
         Tada } from 'react-micron'
 
const App = () => (
  <Bounce events={[]} duration={0.1} timing="ease-in">
    {(interaction, micron) => (
      <button
        onClick={interaction}
        onMouseOver={() =>
          micron().interaction('bounce').duration(2).timing('linear')
        }
      >
        Click me!
      </button>
    )}
  </Bounce>
)
 
export default App

Or equivalently using the corresponding HOC

import React from 'react'
import { withBlink,
         withBounce,
         withFade,
         withFlicker,
         withGroove,
         withJelly,
         withJerk,
         withPop,
         withShake,
         withSqueeze,
         withSwing,
         withTada } from 'react-micron'
 
const App = ({ interaction, micron }) => (
  <button
    onClick={interaction}
    onMouseOver={() =>
      micron().interaction('bounce').duration(2).timing('linear')
    }
  >
    Click me!
  </button>
)
 
export default withBounce(App, {
  events: [],
  timing: 'ease-in',
  duration: 0.1
})

In the above 2 examples setting events to an empty array disables any of the interaction done by react-micron. This can then be triggered by using the interaction callback or using the micron API directly.

This allows animations of different speeds or timing to be triggered depending on how the interaction is triggered.

Custom Interactions

Custom interactions can be defined by using the Custom component.

This can be done by adding a CSS class mjs-<type> where type is some string identifier for the interaction, passed to the component as a prop.

This can be done via regular CSS imports however in this example CSS-in-JS will be used with Emotion:

/** @jsx jsx */
import React from 'react'
import { Custom } from 'react-micron'
import { Global, css, keyframes, jsx } from '@emotion/react'
 
const shiftAnimation = keyframes`
  0% {
    transform: translate3d(0, 0, 0);
  }
  50% {
    transform: translate3d(10px, -5px, 0);
  }
  60% {
    transform: translate3d(5px, -2.5px, 0);
  }
  80% {
    transform: translate3d(2px, -1.25px, 0);
  }
  100% {
    transform: translate3d(0, 0, 0);
  }
`
 
const style = css`
 .mjs-shift {
    animation: ${shiftAnimation};
 }
`
 
const Shift = props => (
  <>
    <Global styles={style} />
    <Custom {...props} type="shift" />
  </>
)
 
export default Shift
