Installation

``shell
npm install @tidbcloud/tisqleditor-react
`

You need to install all its peer dependencies manually as well, such as @codemirror/view, @codemirror/state.

Usage

@tidbcloud/tisqleditor-react supports multiple CodeMirror instances, it uses EditorCacheProvider as the context provider to cache the instances, then you can access all the cached editor instances anywhere inside the provider. You can put the provider in a proper place.

`tsx
import { EditorCacheProvider } from '@tidbcloud/tisqleditor-react'

export default function () {
return (



)
}
`

When EditorCacheProvider unmounts, it will clear all the cached editor instances.

`tsx
import { SQLEditor } from '@tidbcloud/tisqleditor-react'

export function () {
// ...

return (
className="h-full"
editorId={activeFile.id}
doc={activeFile.content}
sqlConfig={sqlConfig}
theme={isDark ? oneDark : bbedit}
extraExts={extraExts}
/>
)
}
`

Inside the SQLEditor, it will check whether the editor instance already exists from the cached editor instances by editorId, if doesn't exist, it will create a new editor instance, and add to the cache automatically, else use the existed editor instance directly.

When you want to remove an editor instance from the cache, for example, close an opened SQL file, you need to do it manually.

`tsx
import { useEditorCacheContext } from '@tidbcloud/tisqleditor-react'

export function OpenedFilesTabs() {
const {
state: { openedFiles }
} = useFilesContext()
const cacheCtx = useEditorCacheContext()

function handleCloseFile(file: IFile) {
// ...

// remove from cache
cacheCtx.deleteEditor(file.id)
}

return (


> Notice: if you don't need to support multiple CodeMirror instances, aka you don't need to edit multiple SQL files at the same time, then you don't need to use the , just to use component.
