一个小巧灵活的在 React 中使用 CodeMirror 6 的解决方案，打包体积只有 ~1.5kB minified + gizipped 。

import { createCodeMirror } from '@codemirror-toolkit/react'

const codeMirror = createCodeMirror<HTMLDivElement>((prevState) => ({
  doc: prevState?.doc ?? 'Hello World!',
  // ...otherConfig,
}))

// if you want to use them in other files
export const { useViewEffect, useContainerRef, /* ... */ } = codeMirror

function Editor() {
  useViewEffect((view) => {
    console.log('EditorView is created')
    return () => {
      console.log('EditorView will be destroyed')
    }
  }, [])
  const containerRef = useContainerRef()
  return <div ref={containerRef} />
}

function App() {
  const [showEditor, setShowEditor] = useState(true)
  return (
    <>
      <button onClick={() => setShowEditor(!showEditor)}>
        {showEditor ? 'Destroy' : 'Create'} Editor
      </button>
      {showEditor && <Editor />}
    </>
  )
}

可以看出 API 的设计借鉴了 zustand 很多，也可以搭配 Context Provider 来使用：

const {
  Provider: CodeMirrorProvider,
  useView,
  useContainerRef,
  // ...
} = createCodeMirrorWithContext<HTMLDivElement>('CodeMirrorContext')

function MenuBar() {
  const view = useView()
  // ...
}

function Editor() {
  const containerRef = useContainerRef()
  return <div ref={containerRef} />
}

function App({ initialInput }: { initialInput: string }) {
  return (
    <CodeMirrorProvider
      config={{
        doc: initialInput,
        // ...otherConfig,
      }}>
      <MenuBar />
      <Editor />
    </CodeMirrorProvider>
  )
}
