how to append data with api

[lz520520]

If the data is updated externally, it is currently done by modifying the value, but this causes the entire content to be re-rendered, I would like to append new data without affecting the original content, how can this be achieved, I checked the documentation and didn't find any way to do this.

@lz520520 I have a component(uiwjs/react-markdown-editor/core/src/commands/code.tsx) that might help with your issue. You can refer to the following example for updating the method:

    view.dispatch({
      changes: {
        from: main.from,
        to: main.to,
        insert: `\`\`\`js\n${txt}\n\`\`\``,
      },
      selection: EditorSelection.range(main.from + 3, main.from + 5),
    });

Thank you very much, referring to the example you provided I solved the problem, the following is my demo, used to append data at the end of the editor

  const appendText = (text: string) => {
      const view = editorRef.current?.view as EditorView;
      view.dispatch({
          changes: { from: view.state.doc.length, insert:  text},
      });
  };
