## v4 changes
|
|
|
|
See also the [CHANGELOG](https://github.com/suren-atoyan/monaco-react/blob/master/CHANGELOG.md)
|
|
|
|
`v4` brings lots of new features and some breaking changes. First, let's see what's broken comparing with the `v3`
|
|
|
|
1) `editorDidMount` - **removed**
|
|
|
|
In the new version there is no `editorDidMount` property. Now it can be replaced by `onMount`. If you happen to remember, the signature of `editorDidMount` was `function(getEditorValue: () => string, editor: monaco.editor.IStandaloneCodeEditor) => void`
|
|
|
|
The `onMount` prop is a little bit different, the signature is `function(editor: monaco.editor.IStandaloneCodeEditor, monaco: Monaco) => void`. As you can see it also exposes the `monaco` instance as a second parameter. There is no `getEditorValue`. To get the current model value you can use `editor` instance (`editor.getValue()`) or `onChange` prop. [Read more](https://github.com/suren-atoyan/monaco-react#get-value)
|
|
|
|
2) `beforeMount` - **new** (`onMount` - **new**)
|
|
|
|
In addition to `onMount` now there is also `beforeMount` that exposes the `monaco` instance as a first parameter. Here you can do something before the editor is mounted. [Read more](https://github.com/suren-atoyan/monaco-react#monaco-instance)
|
|
|
|
3) `ControlledEditor` - **removed**
|
|
|
|
`ControlledEditor` component is removed. Now there is one `Editor` component that behaves in `controlled` mode or `uncontrolled` mode based on the usage of `value` property. [Read more](https://github.com/suren-atoyan/monaco-react#uncontrolled-controlled-modes)

|
4) `multi-model editor` - **new**
