Interactive node views

Introduction

Node views are the best thing since sliced bread, at least if you are a fan of customization (and bread). With node views you can add interactive nodes to your editor. That can literally be everything. If you can write it in JavaScript, you can use it in your editor.

Node views are amazing to improve the in-editor experience, but can also be used in a read-only instance of Tiptap. They are unrelated to the HTML output by design, so you have full control about the in-editor experience and the output.

Different types of node views

Depending on what you would like to build, node views work a little bit different and can have their verify specific capabilities, but also pitfalls. The main question is: How should your custom node look like?

Editable text

Yes, node views can have editable text, just like a regular node. Thats simple. The cursor will exactly behave like you would expect it from a regular node. Existing commands work very well with those nodes.

<div class="Prosemirror" contenteditable="true">
  <p>text</p>
  <node-view>text</node-view>
  <p>text</p>
</div>

Thats how the TaskItem node works.

Non-editable text

Nodes can also have text, which is not editable. The cursor cant jump into those, but you dont want that anyway.

tiptap adds a contenteditable="false" to those by default.

<div class="Prosemirror" contenteditable="true">
  <p>text</p>
  <node-view contenteditable="false">text</node-view>
  <p>text</p>
</div>

Thats how you could render mentions, which shouldnt be editable. Users can add or delete them, but not delete single characters.

Statamic uses those for their Bard editor, which renders complex modules inside Tiptap, which can have their own text inputs.

Mixed content

You can even mix non-editable and editable text. Thats great to build complex things, and still use marks like bold and italic inside the editable content.

BUT, if there are other elements with non-editable text in your node view, the cursor can jump there. You can improve that with manually adding contenteditable="false" to the specific parts of your node view.

<div class="Prosemirror" contenteditable="true">
  <p>text</p>
  <node-view>
    <div contenteditable="false">
      non-editable text
    </div>
    <div>
      editable text
    </div>
  </node-view>
  <p>text</p>
</div>

Markup

But what happens if you access the editor content? If youre working with HTML, youll need to tell Tiptap how your node should be serialized.

The editor does not export the rendered JavaScript node, and for a lot of use cases you wouldnt want that anyway.

Lets say you have a node view which lets users add a video player and configure the appearance (autoplay, controls …). You want the interface to do that in the editor, not in the output of the editor. The output of the editor should probably only have the video player.

I know, I know, its not that easy. Just keep in mind, that youre in full control of the rendering inside the editor and of the output.

:::warning What if you store JSON? That doesnt apply to JSON. In JSON, everything is stored as an object. There is no need to configure the “translation” to and from JSON. :::

Render HTML

Okay, youve set up your node with an interactive node view and now you want to control the output. Even if your node view is pretty complex, the rendered HTML can be simple:

renderHTML({ HTMLAttributes }) {
  return ['my-custom-node', mergeAttributes(HTMLAttributes)]
},

// Output: <my-custom-node count="1"></my-custom-node>

Make sure its something distinguishable, so its easier to restore the content from the HTML. If you just need something generic markup like a <div> consider to add a data-type="my-custom-node".

Parse HTML

The same applies to restoring the content. You can configure what markup you expect, that can be something completely unrelated to the node view markup. It just needs to contain all the information you want to restore.

Attributes are automagically restored, if you registered them through addAttributes.

// Input: <my-custom-node count="1"></my-custom-node>

parseHTML() {
  return [{
    tag: 'my-custom-node',
  }]
},

Render JavaScript/Vue/React

But what if you want to render your actual JavaScript/Vue/React code? Consider using Tiptap to render your output. Just set the editor to editable: false and no one will notice youre using an editor to render the content. :-)
