css-transition

CSSTransition component for adding classes to an element while it is transitioning

Installation

$ npm install vdux-css-transition

Usage

Use this component to apply classes to your nodes when they are being added/removed from the DOM. It works like this:

function render () {
  return (
    <CSSTransition timeout={500}>
      <Tooltip />
    </CSSTransition>
  )
}

Each child of <CSSTransition/> will have the following classes added to it:

• enter - Immediately on creation
• enter-active - On the next tick after the enter class is added
• leave - When the component begins leaving
• leave-active - On th enext tick after the leave class is added

API - props

• timeout - (Object|Number). If you specify a number, it'll be used as both the enter and leave timeout lengths in milliseconds. You may alternatively passn an object with enter and leave keys to specify them independently.

Fade example (using jss-simple for css)

import css from 'jss-simple'

function render () {
  return (
    <CSSTransition timeout={150}>
      <div class={fade}>I am fading in</div>
    </CSSTransition>
  )
}

const {fade} = css({
  fade: {
    '&.enter': {
      opacity: 0,
      '&.enter-active': {
        transition: 'opacity .15s linear',
        opacity: 1
      },
    },
    '&.leave': {
      opacity: 1,
      '&.leave-active': {
        opacity: 0,
        transition: 'opacity .15s linear'
      }
    }
  }
})
