# Node views with JavaScript
|
||
|
||
## Introduction
|
||
Using frameworks like Vue or React can feel too complex, if you’re used to work without those two. Good news: You can use Vanilla JavaScript in your node views. There is just a little bit you need to know, but let’s go through this one by one.
|
||
|
||
## Render a node view with JavaScript
|
||
Here is what you need to do to render a node view inside your editor:
|
||
|
||
1. [Create a node extension](/guide/custom-extensions)
|
||
2. Register a new node view with `addNodeView()`
|
||
3. Write your render function
|
||
4. [Configure Tiptap to use your new node extension](/guide/configuration)
|
||
|
||
This is how your node extension could look like:
|
||
|
||
```js
|
||
import { Node } from '@tiptap/core'
|
||
|
||
export default Node.create({
|
||
// configuration …
|
||
|
||
addNodeView() {
|
||
return ({ editor, node, getPos, HTMLAttributes, decorations, extension }) => {
|
||
const dom = document.createElement('div')
|
||
|
||
dom.innerHTML = 'Hello, I’m a node view!'
|
||
|
||
return {
|
||
dom,
|
||
}
|
||
}
|
||
},
|
||
})
|
||
```
|
||
|
||
Got it? Let’s see it in action. Feel free to copy the below example to get started.

|
||
|
||
That node view even interacts with the editor. Time to see how that is wired up.
|
||
|
||
## Access node attributes
|
||
The editor passes a few helpful things to your render function. One of them is the `node` prop. This one enables you to access node attributes in your node view. Let’s say you have [added an attribute](/guide/custom-extensions#attributes) named `count` to your node extension. You could access the attribute like this:
|
||
|
||
```js
|
||
addNodeView() {
|
||
return ({ node }) => {
|
||
console.log(node.attrs.count)
|
||
|
||
// …
|
||
}
|
||
}
|
||
```
|
||
|
||
|
||
## Update node attributes
|
||
You can even update node attributes from your node view, with the help of the `getPos` prop passed to your render function. Dispatch a new transaction with an object of the updated attributes:
|
||
|
||
```js
|
||
addNodeView() {
|
||
return ({ editor, node, getPos }) => {
|
||
const { view } = editor
|
||
|
||
// Create a button …
|
||
const button = document.createElement('button')
|
||
button.innerHTML = `This button has been clicked ${node.attrs.count} times.`
|
||
|
||
// … and when it’s clicked …
|
||
button.addEventListener('click', () => {
|
||
if (typeof getPos === 'function') {
|
||
// … dispatch a transaction, for the current position in the document …
|
||
view.dispatch(view.state.tr.setNodeMarkup(getPos(), undefined, {
|
||
count: node.attrs.count + 1,
|
||
}))
|
||
|
||
// … and set the focus back to the editor.
|
||
editor.commands.focus()
|
||
}
|
||
})
|
||
|
||
// …
|
||
}
|
||
}
|
||
```
|
||
|
||
Does seem a little bit too complex? Consider using [React](/guide/node-views/react) or [Vue](/guide/node-views/vue), if you have one of those in your project anyway. It get’s a little bit easier with those two.
|
||
|
||
## Adding a content editable
|
||
To add editable content to your node view, you need to pass a `contentDOM`, a container element for the content. Here is a simplified version of a node view with non-editable and editable text content:
|
||
|
||
```js
|
||
// Create a container for the node view
|
||
const dom = document.createElement('div')
|
||
|
||
// Give other elements containing text `contentEditable = false`
|
||
const label = document.createElement('span')
|
||
label.innerHTML = 'Node view'
|
||
label.contentEditable = false
|
||
|
||
// Create a container for the content
|
||
const content = document.createElement('div')
|
||
|
||
// Append all elements to the node view container
|
||
dom.append(label, content)
|
||
|
||
return {
|
||
// Pass the node view container …
|
||
dom,
|
||
// … and the content container:
|
||
contentDOM: content,
|
||
}
|
||
```
|
||
|
||
Got it? You’re free to do anything you like, as long as you return a container for the node view and another one for the content. Here is the above example in action:
|
||
|
||
https://embed.tiptap.dev/preview/GuideNodeViews/JavaScriptContent
|
||
|
||
Keep in mind that this content is rendered by Tiptap. That means you need to tell what kind of content is allowed, for example with `content: 'inline*'` in your node extension (that’s what we use in the above example).
