This message clearly communicates the change in maintenance status and invites interested contributors to get in touch.

react-native-cn-quill

react-native-cn-quill is a rich-text editor for react-native. We've created this library on top of Quill Api.

Why Quill

Quill is a free, open source WYSIWYG editor built for the modern web. Completely customize it for any need with its modular architecture and expressive API. Read more here.

Prerequisite

This package is using react-native-webview. Please follow this document to install it.

Installation

Install using npm:

npm i react-native-cn-quill

Install using yarn:

yarn add react-native-cn-quill

Usage

Here is a simple overview of our components usage.

import React from 'react';
import { SafeAreaView, StyleSheet, StatusBar } from 'react-native';
import QuillEditor, { QuillToolbar } from 'react-native-cn-quill';
export default function App() {
  const _editor = React.createRef();

  return (
    <SafeAreaView style={styles.root}>
      <StatusBar style="auto" />
      <QuillEditor
        style={styles.editor}
        ref={_editor}
        initialHtml="<h1>Quill Editor for react-native</h1>"
      />
      <QuillToolbar editor={_editor} options="full" theme="light" />
    </SafeAreaView>
  );
}

const styles = StyleSheet.create({
  title: {
    fontWeight: 'bold',
    alignSelf: 'center',
    paddingVertical: 10,
  },
  root: {
    flex: 1,
    marginTop: StatusBar.currentHeight || 0,
    backgroundColor: '#eaeaea',
  },
  editor: {
    flex: 1,
    padding: 0,
    borderColor: 'gray',
    borderWidth: 1,
    marginHorizontal: 30,
    marginVertical: 5,
    backgroundColor: 'white',
  },
});

  class PlainListItem extends ListItem {
    formatAt(index, length, name, value) {
      if (name === 'list') {
        // Allow changing or removing list format

`getLeaf(index: Number): Promise<{ offset: number; text: string; length: number; index: number; attributes: Record<string, string> }>`

Returns the leaf Blot at the specified index within the document. But RN can't push node thought webview event, will return simple result about selection attributes gets from first main parent of leaf

Example:

quill.setText('Hello Good World!');
quill.formatText(6, 4, "bold", true);

let [leaf, offset] = quill.getLeaf(7);
// leaf should be a Text Blot with value "Good"
// offset should be 1, since the returned leaf started at index 6, with text "Good" and length 4

Formatting Methods

`format(name: String, value: any)`

Format text at user’s current selection.

Example:

_editor.current.format('color', 'red');

`removeFormat(index: number, length: number): Promise<Delta>`

});

quill.formatText(5, 1, 'align', 'right');  // right aligns the 'hello' line

Selection Methods

`getBounds(index: Number, length: Number = 0)`

Retrieves the pixel position and dimensions of a selection at a given location.

Example:

//Ex. Returns { height: 15, width: 0, left: 27, top: 31 }

`getSelection(focus = false) : { index: Number, length: Number }`

  } else {
    var text = quill.getText(range.index, range.length);

Clipboard Methods

`dangerouslyPasteHTML(index: number, html: string)`

Inserts content represented by HTML snippet into editor at a given index.

Example:

_editor.current.dangerouslyPasteHTML(0, '<b>Hello World</b>');

Read about these methods and their functionality on Quill Api

QuillToolbar

The QuillToolbar component allow users to easily format Quill’s contents. QuillToolbar controls can be specified by a simple array of format names like ['bold', 'italic', 'underline', 'strike'] or by just passing 'basic' or 'full' string to options prop. we've tried to develop it just like Quill Toolbar options.

If you prefer to use quill's built-in toolbar follow this instruction.

The QuillToolbar uses a series of icons to render controls. this controls by default applies and removes formatting, but you can easily extend or overwrite these with custom prop. For example we may add the image and clock (user defined control that inserts current date to the editor) handlers just like this:

Custom Handlers Usage

...
  const clockIcon = require('../assets/icons/clock.png');

  customHandler = (name: string, value: any) => {
    if (name === 'image') {
      this._editor.current?.insertEmbed(
        0,
        'image',
        'https://picsum.photos/200/300'
      );
    } else if (name === 'clock') {
      this._editor.current?.insertText(0, `Today is ${this.getCurrentDate()}`, {
        bold: true,
        color: 'red',
      });
    } else {
      console.log(`${name} clicked with value: ${value}`);
    }
  };

  render() {
    ...
        <QuillToolbar
          editor={this._editor}
          options={['image', 'clock']}
          theme="light"
          custom={{
            handler: this.customHandler,
            actions: ['image', 'clock'],
            icons: {
              clock: clockIcon,
            },
          }}
        />
        ...
  }
