Scroll problem

###usecontainer = {true} Need to be placed in ScrolView and add a callback method oncursorPosition to handle scroll bar positioning, refer to Examples this.scrollRef.current.scrollTo({y: scrollY - 30, animated: true});

`RichEditor`

The editor component. Simply place this component in your view hierarchy to receive a fully functional Rich text Editor.

RichEditor takes the following optional props:

html

Accepts custom HTML, allowing you to make your own customizations
placeholder

Wrap the editor content placeholder
initialContentHTML

HTML that will be rendered in the content section on load.
initialFocus
Boolean value to Initial content request focus. The default value is false.
disabled
Boolean value to disable editor. The default value is false.
enterKeyHint
String value to set return key type - returnKeyType
editorInitializedCallback

A function that will be called when the editor has been initialized.
editorStyle

Styling for container or for Rich Editor more dark or light settings. Object containing the following options:
- backgroundColor: Editor background color
- color: Editor text color
- caretColor cursor/selection color
- placeholderColor: Editor placeholder text color
- contentCSSText: editor content css text（initial valid）
- cssText: editor global css text（initial valid）
- initialCSSText: injects CSS at the beginning of the inline stylesheet. Useful for incorporating custom fonts (see below).
onChange Callback after editor data modification
onHeightChange Callback after height change

onMessage Callback outside postMessage internal type processing

<img src="" onclick="_.sendEvent('ImgClick')" contenteditable="false"/>

command Execute JS in the editor

 // $ = document
 this.richText.current?.commandDOM('$.execCommand('insertHTML', false, "<br/>")');

commandDOM Manipulate the DOM in the editor

 // $ = document.querySelector
 this.richText.current?.commandDOM(`$('#title').style.color='${color}'`);

useContainer A boolean value that determines if a View container is wrapped around the WebView. The default value is true. If you are using your own View to wrap this library around, set this value to false.
styleWithCSS When true, style attribute of tags are modified. Otherwise dedicated tags are created. The default value is false
initialHeight useContainer is false by inline view of initial height
pasteAsPlainText A boolean value (false as default) that determines if the clipboard paste will keep its format or it will be done as plain text
useCharacter The option to disable Chinese characters allows you to support English characters without errors on Android. Set to true by default for backwards compatibility.
defaultHttps A boolean value (true as default) that prepends https:// to the start of links
onPaste Callback clipboard paste value
onKeyUp Callback Keyup event (Android 229 bug)
onKeyDown Callback Keydown event (Android 229 bug)
onInput Callback input value
onLink Callback link click
onFocus Callback editor focus
onBlur Callback editor blur
onCursorPosition Callback Enter the position of the cursor this.scrollRef.current.scrollTo({y: scrollY - 30, duration: 100, animated: true});

RichEditor also has methods that can be used on its ref to set:

setContentHTML(html: string)
insertImage(url: string, style?: string)
insertLink(title: string, url: string)
insertText(text: string)
insertHTML(html: string)
insertVideo(url: string, style?: string)
setContentFocusHandler(handler: Function)
blurContentEditor()
focusContentEditor()

This method registers a function that will get called whenver the cursor position changes or a change is made to the styling of the editor at the cursor's position., The callback will be called with an array of actions that are active at the cusor position, allowing a toolbar to respond to changes.

registerToolbar(listener: Function)

Example Usage:

<RichEditor
  ref={(r) => this.richtext = r}
  initialContentHTML={'Hello <b>World</b> <p>this is a new paragraph</p> <p>this is another new paragraph</p>'}
  editorInitializedCallback={() => this.onEditorInitialized()}
/>

Using Custom Fonts

In order to use custom fonts, you need to use initialCSSText from the editorStyle prop.

Upload your font files to https://transfonter.org and check the 'base64' option. When you download the zip file, there will be a stylesheet.css file there.
Take your stylesheet.css file and create a stylesheet.js file.
Create an export and paste the contents of the css file there. e.g.:

const FontFamilyStylesheet = `
@font-face {
    font-family: 'Your Font Family';
    src: url('data:font/ttf;charset=utf-8;base64,...............'); // You can also use a web url here
    font-weight: normal;
}
`;

export default FontFamilyStylesheet;

Where you've incorporated your RichEditor component, import the file and utilize it.

import FontFamilyStylesheet from 'stylesheet.js';

const fontFamily = 'Your_Font_Family';
const initialCSSText = { initialCSSText: `${FontFamilyStylesheet}`, contentCSSText: `font-family: ${fontFamily}` }
<RichEditor editorStyle={initialCSSText}/>

Reload the app. You should now be seeing your Rich Editor content in your custom font face!

For more info on how initialCSSText works, check out the PR here. Also, credit to this issue comment and his fork that describes how to use the base64 encoded font file.

`RichToolbar`

This is a Component that provides a toolbar for easily controlling an editor. It is designed to be used together with a RichEditor component.

The RichToolbar has one required property:

getEditor()

Which must provide a function that returns a ref to a RichEditor component.

This is because the ref is not created until after the first render, before which the toolbar is rendered. This means that any ref passed directly will inevitably be passed as undefined.

Other props supported by the RichToolbar component are:

actions

An array of actions to be provided by this toolbar. The default actions are:
- actions.insertImage
- actions.setBold
- actions.setItalic
- actions.insertBulletsList
- actions.insertOrderedList
- actions.insertLink
- actions.keyboard
- actions.setStrikethrough
- actions.setUnderline
- actions.removeFormat
- actions.insertVideo
- actions.checkboxList
- actions.undo
- actions.redo
onPressAddImage Functions called when the addImage actions are tapped.
onInsertLink Logic for what happens when you press on the add insert link button
disabled
Boolean value to disable editor. The default value is false.
iconTint
unselectedButtonStyle
selectedIconTint
selectedButtonStyle
disabledIconTint
disabledButtonStyle

These provide options for styling action buttons.
iconSize

Defines the size of the icon in pixels. Default is 50.
renderAction

Altenatively, you can provide a render function that will be used instead of the default, so you can fully control the tollbar design.
iconMap

RichTextToolbar comes with default icons for the default actions it renders. To override those, or to add icons for non-default actions, provide them in a dictionary to this prop.

Example Usage:

const richText = React.createRef() || useRef();
<RichToolbar editor={that.richText}/>

With Custom Action:

To define your own custom action:

Send your action name as string in the actions array.
Include an icon for it with the iconMap
Add a function prop with the same action name to be called on tap

<RichToolbar
    editor={that.richText}
	actions={[
		actions.setBold,
		actions.setItalic,
		actions.insertBulletsList,
		actions.insertOrderedList,
		actions.insertImage,
		'customAction',
	]}
	iconMap={{
		customAction: customIcon,
	}}
	customAction={this.handleCustomAction}
/>

A Complete Example Using a Functional Component

import React from "react";
import { Text, Platform, KeyboardAvoidingView, SafeAreaView, ScrollView } from "react-native";
import {actions, RichEditor, RichToolbar} from "react-native-pell-rich-editor";


const handleHead = ({tintColor}) => <Text style={{color: tintColor}}>H1</Text>
const TempScreen = () => {
	const richText = React.useRef();
	return (
    <SafeAreaView>
      <ScrollView>
        <KeyboardAvoidingView behavior={Platform.OS === "ios" ? "padding" : "height"}	style={{ flex: 1 }}>
          <Text>Description:</Text>
          <RichEditor
              ref={richText}
              onChange={ descriptionText => {
                  console.log("descriptionText:", descriptionText);
              }}
          />
        </KeyboardAvoidingView>
      </ScrollView>

      <RichToolbar
        editor={richText}
        actions={[ actions.setBold, actions.setItalic, actions.setUnderline, actions.heading1 ]}
        iconMap={{ [actions.heading1]: handleHead }}
      />
    </SafeAreaView>
  );
};

export default TempScreen;
