How to update nodeview from outside

let nodeViews = [];

let editor = new EditorView( this._editor_show_el , {

    state: EditorState.create({
        doc: doc,

    nodeViews: {

        'mainbody'(node, view, getPos) {

            let obj = new MainbodyView(node, view, getPos, {


            return obj;



setTimeout(x => {

  console.log('nodeViews[0]', nodeViews[0]);
  // update it

}, 1000);

At present, I do like this, which can realize my needs, but if it is multi person real-time cooperation, it will not work well

Node decorations can be used to pass information to node views (though those are also not the easiest thing to set up). I think there is a need for some imperative way to force node views to redraw, but I’m not sure what it would look like yet.

For you, would a view method that broadcasts a given object to all node views in the document (allowing them to run their own update logic, and possibly opt to be redrawn entirely through a return value) work?

Node decorations may not be enough

My requirement is that there is a Mind map component in nodeview, and the interface inside can be updated from the outside when multiple people collaborate in real time.

At present, it is achievable but not elegant
