react-drag-sizing

npm i -S react-drag-sizing
import DragSizing from 'react-drag-sizing'

<div className="chat-top"></div>
<div className="chat-body">
  <div className="chat-left">
    <MessageList />
    <DragSizing border="top">
      <Editor />
    </DragSizing>
  </div>
  <div className="chat-right">

</div>

Props

export type MEvent = MouseEvent | TouchEvent;
export type RdsMEvent =
  | MouseEvent
  | (TouchEvent & {
      clientX: number;
      clientY: number;
    });

export interface DragSizingProps {
  border: 'top' | 'bottom' | 'left' | 'right';
  onStart?: (e: RdsMEvent) => void;
  onEnd?: (e: RdsMEvent) => void;
  onUpdate?: (e: RdsMEvent) => void;
  id?: string;
  className?: string;
  style?: React.CSSProperties;
  handlerClassName?: string;
  handlerStyle?: React.CSSProperties;
  handlerWidth?: number;
  handlerOffset?: number;
  handlerZIndex?: number;
}

hooking event listeners

handleEditorSizingStart = () => {
  // const nearBottom = scrollTop > ...
  setShouldStickToBottom(nearBottom);
};
handleEditorSizingEnd = () => {
  if (shouldStickToBottom) {
    scrollToBottom();
  }
};

<DragSizing
  border="top"
  onStart={handleEditorSizingStart}
  onEnd={handleEditorSizingEnd}
>
  <Editor />
</DragSizing>;

for umd / <script> usage

<script src="https://unpkg.com/react"></script>
<script src="https://unpkg.com/react-dom"></script>
<script src="https://unpkg.com/react-drag-sizing"></script>
<script src="myapp.js"></script>
// myapp.js
let React = window.React;
let ReactDOM = window.ReactDOM;
let { DragSizing } = window.ReactDragSizing;

ReactDOM.render(
  <div style={{ display: 'flex' }}>
    <sidebar style={{ flex: 1 }}>Left bar</sidebar>
    <DragSizing
      border="left"
      style={{ minWidth: '15%', maxWidth: '85%', width: '50%' }}
      handlerStyle={{ backgroundColor: 'rgba(0, 0, 0, 0.2)' }}
    >
      <main>Main content</main>
    </DragSizing>
  </div>,
  mountNode
);

for react < 16.8 we need hooks polyfill workaround
