        type: "doc",
        content: [
            {

Custom Nodes

Define your node as a class -

const Node = require("html-to-prosemirror").Node;

class CustomNode extends Node {
    matching () {
        return this.DOMNode.nodeName === "USER"; // uses `jsdom` library
    }

    data () {
        return {
            type: "user",
            attrs: {
                id: this.DOMNode.getAttribute("data-id")
            }
        };
    }
}

Feed it to renderer instance -

renderer.addNode(CustomNode);
