` for you, to be used as the editing area for Quill. If you prefer, you can specify your own element for ReactQuill to use. Note that `

`s are not supported by Quill at this time.

Note: Custom editing areas lose focus when using React 16 as a peer dep at this time ([bug](https://github.com/zenoamaro/react-quill/issues/309)).

```jsx
class MyComponent extends React.Component {

render() {
    return (
      <ReactQuill>
        <div className="my-editing-area"/>
      </ReactQuill>
    );
  }

});
```

## Upgrading to ReactQuill v2

Upgrading to ReactQuill v2 should be as simple as updating your dependency. However, it also removes support for long-deprecated props, the ReactQuill Mixin, and the Toolbar component.

### Deprecated props

Support for the `toolbar`, `styles`, `pollInterval` Quill options has long disabled. Starting from this release, ReactQuill will not warn you anymore if you try using them.

### ReactQuill Mixin

The ReactQuill Mixin allowed injecting the core functionality that made ReactQuill tick into your own components, and create deeply customized versions.

The Mixin has been considered an anti-pattern for a long time now, so we have decided to finalize its deprecation.

There is no upgrade path. If you have a use case that relied on the Mixin, you're encouraged to open an issue, and we will try to provide you with a new feature to make it possible, or dedicated support to migrate out of it.

### Toolbar component

Quill has long provided built-in support for custom toolbars, which replaced ReactQuill's (quite inflexible) Toolbar component.

Use the [Toolbar Module](#default-toolbar-elements) or the [HTML Toolbar](#html-toolbar) feature instead.

## API reference

### Exports

```jsx
// ES6
import ReactQuill, { Quill } from 'react-quill';

// CommonJS
const ReactQuill = require('react-quill');
const { Quill } = ReactQuill;
```

`Quill`
: The `Quill` namespace on which you can call `register`.

### Props

`id`
: ID to be applied to the DOM element.

`className`
: Classes to be applied to the DOM element.

`value`
: Value for the editor as a controlled component. Can be a string containing HTML, a [Quill Delta](https://quilljs.com/docs/delta/) instance, or a plain object representing a Delta.
Note that due to limitations in Quill, this is actually a _semi-controlled_ mode, meaning that the edit is not prevented, but changing `value` will still replace the contents.
Also note that passing a Quill Delta here, and then an HTML string, or vice-versa, will always trigger a change, regardless of whether they represent the same document.
⚠️ Do not pass the `delta` object from the `onChange` event as `value`, as it will cause a loop. See [Using Deltas](#using-deltas) for details.

`defaultValue`
: Initial value for the editor as an uncontrolled component. Can be a string containing HTML, a [Quill Delta](https://quilljs.com/docs/delta/), or a plain object representing a Delta.

`readOnly`
: If true, the editor won't allow changing its contents. Wraps the Quill [`disable` API](https://quilljs.com/docs/api/#enable).

`placeholder`
: The default value for the empty editor. Note: The Quill API does not support changing this value dynamically. Use refs and data-attributes instead (see [#340](https://github.com/zenoamaro/react-quill/issues/340#issuecomment-376176878)).

`modules`
: An object specifying which modules are enabled, and their configuration. The editor toolbar is a commonly customized module. See the [modules section](http://quilljs.com/docs/modules/) over the Quill documentation for more information on what modules are available.

`formats`
: An array of formats to be enabled during editing. All implemented formats are enabled by default. See [Formats](http://quilljs.com/docs/formats/) for a list.
Custom formats should not be included in the array as of version 1.0.0. Instead they should be created through [Parchment](https://github.com/quilljs/parchment) and registered with the module's [Quill export](#exports).

`style`
: An object with custom CSS rules to apply on the editor's container. Rules should be in React's "camelCased" naming style.

`theme`
: The name of the theme to apply to the editor. Defaults to `snow`, Quill's standard theme. Pass `null` to use the minimal core theme. See the [docs on themes](#themes) for more information on including the required stylesheets.

`tabIndex`
: The order in which the editor becomes focused, among other controls in the page, during keyboard navigation.

`bounds`
: Selector or DOM element used by Quill to constrain position of popups. Defaults to `document.body`.

`children`
: A single React element that will be used as the editing area for Quill in place of the default, which is a `<div>`. Note that you cannot use a `<textarea>`, as it is not a supported target. Also note that updating children is costly, as it will cause the Quill editor to be recreated. Set the `value` prop if you want to control the html contents of the editor.

`onChange(content, delta, source, editor)`
: Called back with the new contents of the editor after change. It will be passed the HTML contents of the editor, a delta object expressing the change, the source of the change, and finally a read-only proxy to [editor accessors](#the-unprivileged-editor) such as `getHTML()`.
⚠️ Do not use this `delta` object as `value`, as it will cause a loop. Use `editor.getContents()` instead. See [Using Deltas](#using-deltas) for details.

`onChangeSelection(range, source, editor)`
: Called back with the new selected range, or null when unfocused. It will be passed the selection range, the source of the change, and finally a read-only proxy to editor accessors such as `getBounds()`.

`onFocus(range, source, editor)`
: Called when the editor becomes focused. It will receive the new selection range.

`onBlur(previousRange, source, editor)`
: Called when the editor loses focus. It will receive the selection range it had right before losing focus.

`onKeyPress(event)`
: Called after a key has been pressed and released.
: Note that, like its native counterpart, this won't be called for special keys such as <kbd>shift</kbd> or <kbd>enter</kbd>. If you need those, hook onto `onKeyDown` or `onKeyUp`.

`onKeyDown(event)`
: Called after a key has been pressed, but before it is released.
: Note that, due to how Quill works, it's possible that you won't receive events for keys such as <kbd>enter</kbd>, <kbd>backspace</kbd> or <kbd>delete</kbd>. If that's the case, try hooking onto `onKeyUp` instead.

`onKeyUp(event)`
: Called after a key has been released.

`preserveWhitespace`
: If true, a `pre` tag is used for the editor area instead of the default `div` tag. This prevents Quill from
collapsing continuous whitespaces on paste. [Related issue](https://github.com/quilljs/quill/issues/1751).

### Methods

If you have [a ref](https://facebook.github.io/react/docs/more-about-refs.html) to a ReactQuill node, you will be able to invoke the following methods:

`focus()`
: Focuses the editor.

`blur()`
: Removes focus from the editor.

`getEditor()`
: Returns the Quill instance that backs the editor. While you can freely use this to access methods such as `getText()`, please avoid from imperatively manipulating the instance, to avoid getting ReactQuill and Quill out-of-sync. A much-safer [unprivileged editor](#the-unprivileged-editor) is available as replacement.

<details>
<summary>Example</summary>

[View this example on Codepen](https://codepen.io/alexkrolick/pen/YNmGar?editors=0011)

```jsx
class Editor extends React.Component {
  constructor(props) {
    super(props);
    this.quillRef = null; // Quill instance
    this.reactQuillRef = null; // ReactQuill component
  }

componentDidMount() {
    this.attachQuillRefs();
  }

componentDidUpdate() {
    this.attachQuillRefs();
  }

attachQuillRefs = () => {
    if (typeof this.reactQuillRef.getEditor !== 'function') return;
    this.quillRef = this.reactQuillRef.getEditor();
  };

insertText = () => {
    var range = this.quillRef.getSelection();
    let position = range ? range.index : 0;
    this.quillRef.insertText(position, 'Hello, World! ');
  };

render() {
    return (
      <div>
        <ReactQuill
          ref={(el) => {
            this.reactQuillRef = el;
          }}
          theme={'snow'}
        />
        <button onClick={this.insertText}>Insert Text</button>
      </div>
    );
  }
}
```

</details>

`makeUnprivilegedEditor`
: Creates an [unprivileged editor](#unprivileged-editor). Pass this method a reference to the Quill instance from `getEditor`. Normally you do not need to use this method since the editor exposed to event handlers is already unprivileged.

<details>
<summary>Example</summary>

```jsx
const editor = this.reactQuillRef.getEditor();
const unprivilegedEditor = this.reactQuillRef.makeUnprivilegedEditor(editor);
// You may now use the unprivilegedEditor proxy methods
unprivilegedEditor.getText();
```

</details>

### The unprivileged editor

During events, ReactQuill will make a restricted subset of the Quill API available as the `editor` argument. This prevents access to destructive methods, which might cause ReactQuill to get out-of-sync with the component. It provides the following methods, which are mostly proxies of existing [Quill methods](https://quilljs.com/docs/api/):

`getLength()`
: Returns the length of the editor contents, in characters, not including any HTML tag.

`getText()`
: Returns the string contents of the editor, not including any HTML tag.

`getHTML()`
: Returns the full HTML contents of the editor.

`getContents()`
: Returns a [Quill Delta](https://quilljs.com/docs/delta/) of the complete document.

`getSelection()`
: Returns the current selection range, or `null` if the editor is unfocused.

`getBounds()`
: Returns the pixel position, relative to the editor container, and dimensions, of a selection, at a given location.

## Building and testing
