React <AutoSizeTransition />

尺寸大小可以随着内容变化而动态变化

A component that scale dynamically according to the internal size

Usage:

yarn add auto-size-transition

import AutoSizeTransition from "auto-size-transition";

<AutoSizeTransition style={{background: 'red'}}>
  {visible ? (
    <div style={{ width: 300, display: "inline-block", padding: 20 }}>
      <p>如果天总也不亮，那就摸黑过生活；</p>
      <p>如果发出声音是危险的，那就保持沉默；</p>
      <p>如果自觉无力发光，那就别去照亮别人。</p>
      <p>但是——但是：</p>
      <p>不要习惯了黑暗就为黑暗辩护；</p>
      <p>不要为自己的苟且而得意洋洋；</p>
      <p>不要嘲讽那些比自己更勇敢、更有热量的人们。</p>
      <p>可以卑微如尘土，不可扭曲如蛆虫。</p>
    </div>
  ) : (
    <div style={{ width: 200, display: "inline-block", padding: 20 }}>
      <p>苟利国家生死以 岂因祸福避趋之</p>
    </div>
  )}
</AutoSizeTransition>;

Motivation

因为从height:0 到 height: auto; transition 是无效的，因为 transition 变化的起点跟终点必须是确定的。故希望有一个组件可以根据内部的大小动态伸缩，同时也有transition的效果。

Because the transition from height: 0 to height: Auto; is invalid, because the start and end of the transition change must be determined. Therefore, we hope that there is a component that can scale dynamically according to the internal size, and also has the effect of transition.
