# Editor
|
||
|
||
## Introduction
|
||
This class is a central building block of Tiptap. It does most of the heavy lifting of creating a working [ProseMirror](https://ProseMirror.net/) editor such as creating the [`EditorView`](https://ProseMirror.net/docs/ref/#view.EditorView), setting the initial [`EditorState`](https://ProseMirror.net/docs/ref/#state.Editor_State) and so on.
|
||
|
||
## Methods
|
||
The editor instance will provide a bunch of public methods. Methods are regular functions and can return anything. They’ll help you to work with the editor.
|
||
|
||
Don’t confuse methods with [commands](/api/commands). Commands are used to change the state of editor (content, selection, and so on) and only return `true` or `false`.
|
||
|
||
### can()
|
||
Check if a command or a command chain can be executed – without actually executing it. Can be very helpful to enable/disable or show/hide buttons.
|
||
|
||
```js
|
||
// Returns `true` if the undo command can be executed
|
||
editor.can().undo()
|
||
```
|
||
|
||
### chain()
|
||
Create a command chain to call multiple commands at once.
|
||
|
||
```js
|
||
// Execute two commands at once
|
||
editor.chain().toggleBold().focus().run()
|
||
```
|
||
|
||
### destroy()
|
||
Stops the editor instance and unbinds all events.
|
||
|
||
```js
|
||
// Hasta la vista, baby!
|
||
editor.destroy()
|
||
```
|
||
|
||
### getHTML()
|
||
Returns the current editor document as HTML
|
||
|
||
```js
|
||
editor.getHTML()
|
||
```
|
||
|
||
### getJSON()
|
||
Returns the current editor document as JSON.

editor.isActive('heading', { level: 2 })
|
||
// Check if it has a specific attribute value, doesn’t care what node/mark it is

## Getters
|
||
|
||
### isEditable
|
||
Returns whether the editor is editable or read-only.
|
||
|
||
```js
|
||
editor.isEditable
|
||
```
|
||
|
||
### isEmpty
|
||
Check if there is content.
|
||
|
||
```js
|
||
editor.isEmpty
|
||
```
|
||
|
||
## Settings
|
||
|
||
### element
|
||
The `element` specifies the HTML element the editor will be binded too. The following code will integrate Tiptap with an element with the `.element` class:
|
||
|
||
```js
|
||
import { Editor } from '@tiptap/core'
|
||
import StarterKit from '@tiptap/starter-kit'
|
||
|
||
new Editor({
|
||
element: document.querySelector('.element'),
|
||
extensions: [
|
||
StarterKit,
|
||
],
|
||
})
|
||
```
|
||
|
||
You can even initiate your editor before mounting it to an element. This is useful when your DOM is not yet available. Just leave out the `element`, we’ll create one for you. Append it to your container at a later date like that:
|
||
|
||
```js
|
||
yourContainerElement.append(editor.options.element)
|
||
```
|
||
|
||
### extensions
|
||
It’s required to pass a list of extensions to the `extensions` property, even if you only want to allow paragraphs.
|
||
|
||
```js
|
||
import { Editor } from '@tiptap/core'
|
||
import StarterKit from '@tiptap/starter-kit'
|
||
import Document from '@tiptap/extension-document'
|
||
import Paragraph from '@tiptap/extension-paragraph'
|
||
import Text from '@tiptap/extension-text'
|
||
import Highlight from '@tiptap/extension-highlight'
|
||
|
||
new Editor({
|
||
// Use the default extensions
|
||
extensions: [
|
||
StarterKit,
|
||
],
|
||
|
||
// … or use specific extensions
|
||
extensions: [
|
||
Document,
|
||
Paragraph,
|
||
Text,
|
||
],
|
||
|
||
// … or both
|
||
extensions: [
|
||
StarterKit,
|
||
Highlight,
|
||
],
|
||
})
|
||
```
|
||
|
||
### content
|
||
With the `content` property you can provide the initial content for the editor. This can be HTML or JSON.
|
||
|
||
```js
|
||
import { Editor } from '@tiptap/core'
|
||
import StarterKit from '@tiptap/starter-kit'
|
||
|
||
new Editor({
|
||
content: `<p>Example Text</p>`,
|
||
extensions: [
|
||
StarterKit,
|
||
],
|
||
})
|
||
```
|
||
|
||
### editable
|
||
The `editable` property determines if users can write into the editor.
|
||
|
||
```js
|
||
import { Editor } from '@tiptap/core'
|
||
import StarterKit from '@tiptap/starter-kit'
|
||
|
||
new Editor({
|
||
content: `<p>Example Text</p>`,
|
||
extensions: [
|
||
StarterKit,
|
||
],
|
||
editable: false,
|
||
})
|
||
```
|
||
|
||
### autofocus
|
||
With `autofocus` you can force the cursor to jump in the editor on initialization.
|
||
|
||
| Value | Description |
|
||
| --------- | ------------------------------------------------------ |
|
||
| `'start'` | Sets the focus to the beginning of the document. |
|
||
| `'end'` | Sets the focus to the end of the document. |
|
||
| `Number` | Sets the focus to a specific position in the document. |
|
||
| `true` | Enables autofocus. |
|
||
| `false` | Disables autofocus. |
|
||
| `null` | Disables autofocus. |
|
||
|
||
```js
|
||
import { Editor } from '@tiptap/core'
|
||
import StarterKit from '@tiptap/starter-kit'
|
||
|
||
new Editor({
|
||
extensions: [
|
||
StarterKit,
|
||
],
|
||
autofocus: false,
|
||
})
|
||
```
|
||
|
||
### enableInputRules
|
||
By default, Tiptap enables all [input rules](/guide/custom-extensions/#input-rules). With `enableInputRules` you can control that.
|
||
|
||
```js
|
||
import { Editor } from '@tiptap/core'
|
||
import StarterKit from '@tiptap/starter-kit'
|
||
|
||
new Editor({
|
||
content: `<p>Example Text</p>`,
|
||
extensions: [
|
||
StarterKit,
|
||
],
|
||
enableInputRules: false,
|
||
})
|
||
```
|
||
|
||
Alternatively you can allow only specific input rules.
|
||
|
||
```js
|
||
import { Editor } from '@tiptap/core'
|
||
import StarterKit from '@tiptap/starter-kit'
|
||
import Link from '@tiptap/extension-link'
|
||
|
||
new Editor({
|
||
content: `<p>Example Text</p>`,
|
||
extensions: [
|
||
StarterKit,
|
||
Link,
|
||
],
|
||
// pass an array of extensions or extension names
|
||
// to allow only specific input rules
|
||
enableInputRules: [Link, 'horizontalRule'],
|
||
})
|
||
```
|
||
|
||
### enablePasteRules
|
||
By default, Tiptap enables all [paste rules](/guide/custom-extensions/#paste-rules). With `enablePasteRules` you can control that.
|
||
|
||
```js
|
||
import { Editor } from '@tiptap/core'
|
||
import StarterKit from '@tiptap/starter-kit'
|
||
|
||
new Editor({
|
||
content: `<p>Example Text</p>`,
|
||
extensions: [
|
||
StarterKit,
|
||
],
|
||
enablePasteRules: false,
|
||
})
|
||
```
|
||
|
||
Alternatively you can allow only specific paste rules.
|
||
|
||
```js
|
||
import { Editor } from '@tiptap/core'
|
||
import StarterKit from '@tiptap/starter-kit'
|
||
import Link from '@tiptap/extension-link'
|
||
|
||
new Editor({
|
||
content: `<p>Example Text</p>`,
|
||
extensions: [
|
||
StarterKit,
|
||
Link,
|
||
],
|
||
// pass an array of extensions or extension names
|
||
// to allow only specific paste rules
|
||
enablePasteRules: [Link, 'horizontalRule'],
|
||
})
|
||
```
|
||
|
||
### injectCSS
|
||
By default, Tiptap injects [a little bit of CSS](https://github.com/ueberdosis/tiptap/tree/main/packages/core/src/style.ts). With `injectCSS` you can disable that.
|
||
|
||
```js
|
||
import { Editor } from '@tiptap/core'
|
||
import StarterKit from '@tiptap/starter-kit'
|
||
|
||
new Editor({
|
||
extensions: [
|
||
StarterKit,
|
||
],
|
||
injectCSS: false,
|
||
})
|
||
```
|
||
|
||
### editorProps
|
||
For advanced use cases, you can pass `editorProps` which will be handled by [ProseMirror](https://prosemirror.net/docs/ref/#view.EditorProps). You can use it to override various editor events or change editor DOM element attributes, for example to add some Tailwind classes. Here is an example:
|
||
|
||
```js
|
||
new Editor({
|
||
// Learn more: https://prosemirror.net/docs/ref/#view.EditorProps
|
||
editorProps: {
|
||
attributes: {
|
||
class: 'prose prose-sm sm:prose lg:prose-lg xl:prose-2xl mx-auto focus:outline-none',
|
||
},
|
||
transformPastedText(text) {
|
||
return text.toUpperCase()
|
||
}
|
||
}
|
||
})
|
||
```
|
||
|
||
You can use that to hook into event handlers and pass - for example - a custom paste handler, too.
|
||
|
||
### parseOptions
|
||
Passed content is parsed by ProseMirror. To hook into the parsing, you can pass `parseOptions` which are then handled by [ProseMirror](https://prosemirror.net/docs/ref/#model.ParseOptions).
|
||
|
||
```js
|
||
new Editor({
|
||
// Learn more: https://prosemirror.net/docs/ref/#model.ParseOptions
|
||
parseOptions: {
|
||
preserveWhitespace: 'full',
|
||
},
|
||
})
|
||
```
|
