Answer 1

From the linked example we can simplify. First we create a wrapper component that will replace the <Match/> tag and wrap it's component:

import React from 'react'
import { Match } from 'react-router'
import { TransitionMotion, spring } from 'react-motion'

const styles = {}

styles.fill = {
  position: 'absolute',
  left: 0,
  right: 0,
  top: 0,
  bottom: 0
}

const MatchTransition = ({ component: Component, ...rest }) => {
  const willLeave = () => ({ zIndex: 1, opacity: spring(0) })

  return (
    <Match {...rest} children={({ matched, ...props }) => (
      <TransitionMotion
        willLeave={willLeave}
        styles={matched ? [ {
          key: props.location.pathname,
          style: { opacity: 1 },
          data: props
        } ] : []}
      >
        {interpolatedStyles => (
          <div>
            {interpolatedStyles.map(config => (
              <div
                key={config.key}
                style={{ ...styles.fill, ...config.style }}
              >
                <Component {...config.data} />
              </div>
            ))}
          </div>
        )}
      </TransitionMotion>
    )} />
  )
}

export default MatchTransition

Then we use it like this:

<MatchTransition pattern='/here' component={About} />
<MatchTransition pattern='/there' component={Home} />
