-For a live example you can take a look at the [embed example](https://github.com/heyscrumpy/tiptap/tree/master/examples/Components/Routes/Embeds).
+The real power of the nodes comes in combination with Vue components. Lets build a iframe node, where you can change its url (this can also be found in our [examples](https://github.com/heyscrumpy/tiptap/tree/master/examples/Components/Routes/Embeds)).

+```js
+import { Node } from 'tiptap'
+
+export default class IframeNode extends Node {
+
+  get name() {
+    return 'iframe'
+  }
+
+  get schema() {
+    return {
+      // here you have to specify all values that can be stored in this node
+      attrs: {

+          default: null,
+        },
+      },
+      group: 'block',
+      selectable: false,
+      // parseDOM and toDOM is still required to make copy and paste work
+      parseDOM: [{
+        tag: 'iframe',
+        getAttrs: dom => ({
+          src: dom.getAttribute('src'),
+        }),
+      }],
+      toDOM: node => ['iframe', {
+        src: node.attrs.src,
+        frameborder: 0,
+        allowfullscreen: 'true',
+      }],
+    }
+  }
+  
+  // return a vue component
+  // this can be an object or an imported component
+  get view() {
+    return {
+      // there are some props available
+      // `node` is a Prosemirror Node Object
+      // `updateAttrs` is a function to update attributes defined in `schema`
+      // `editable` is the global editor prop whether the content can be edited
