API Reference

Props

autoFocus

If true, focuses the input.

Type Default Value Platform
bool false Both

autoCapitalize

Tells input to automatically capitalize certain characters.

  • characters: all characters.
  • words: first letter of each word.
  • sentences: first letter of each sentence.
  • none: don't auto capitalize anything.
Type Default Value Platform
'none' | 'sentences' | 'words' | 'characters' 'sentences' Both

cursorColor

When provided it will set the color of the cursor (or "caret") in the component.

Type Default Value Platform
color system default Android

defaultValue

Provides an initial value for the input. If the string is a valid HTML output of the EnrichedTextInput component (or other HTML that the parser will accept), proper styles will be applied.

Type Default Value Platform
string - Both

editable

If false, text is not editable.

Type Default Value Platform
bool true Both

Note

Setting editable to false will disable all user interactions with the input. However, some programmatic changes (like toggling styles or changing value imperatively) via ref methods will still work.

htmlStyle

A prop for customizing styles appearances.

Type Default Value Platform
HtmlStyle default values from HtmlStyle Both

mentionIndicators

The recognized mention indicators. Each item needs to be a 1 character long string.

Type Default Value Platform
array of string ['@'] Both

onBlur

Callback that's called whenever the input loses focused (is blurred).

Type Default Value Platform
() => void - Both

onChangeHtml

Callback that is called when input's HTML changes.

Payload interface:

interface OnChangeHtmlEvent {
  value: string;
}
  • value is the new HTML.
Type Default Value Platform
(event: NativeSyntheticEvent<OnChangeHtmlEvent>) => void - Both

Tip

Specifying onChangeHtml may have performance implications, especially with large documents, as it requires continuous HTML parsing. If you only need the HTML content at specific moments (e.g., when saving), consider using the getHTML ref method instead. When onChangeHtml is not provided, the component optimizes performance by avoiding unnecessary HTML parsing.

onChangeMention

Callback that gets called anytime user makes some changes to a mention that is being edited.

Payload interface:

interface OnChangeMentionEvent {
  indicator: string;
  text: string;
}
  • indicator is the indicator of the currently edited mention.
  • text contains whole text that has been typed after the indicator.
Type Default Value Platform
(event: OnChangeMentionEvent) => void - Both

onChangeSelection

Callback that is called each time user changes selection or moves the cursor in the input.

Payload interface:

interface OnChangeSelectionEvent {
  start: Int32;
  end: Int32;
  text: string;
}
  • start is the index of the selection's beginning.
  • end is the first index after the selection's ending. For just a cursor in place (no selection), start equals end.
  • text is the input's text in the current selection.
Type Default Value Platform
(event: NativeSyntheticEvent<OnChangeSelectionEvent>) => void - Both

onChangeState

Callback that gets called when any of the styles within the selection changes.

Payload has a bool flag for each style:

interface OnChangeStateEvent {
  isBold: boolean;
  isItalic: boolean;
  isUnderline: boolean;
  isStrikeThrough: boolean;
  isInlineCode: boolean;
  isH1: boolean;
  isH2: boolean;
  isH3: boolean;
  isCodeBlock: boolean;
  isBlockQuote: boolean;
  isOrderedList: boolean;
  isUnorderedList: boolean;
  isLink: boolean;
  isImage: boolean;
  isMention: boolean;
}
Type Default Value Platform
(event: NativeSyntheticEvent<OnChangeStateEvent>) => void - Both

onChangeText

Callback called when any text changes occur in the input.

Payload interface:

interface OnChangeTextEvent {
  value: string;
}
  • value is the new text value of the input.
Type Default Value Platform
(event: NativeSyntheticEvent<OnChangeTextEvent>) => void - Both

onEndMention

Callback that is called when the user no longer edits a mention actively - has moved the cursor somewhere else or put a space and the cursor isn't within the edited mention.

  • indicator is the indicator of the mention that was being edited.
Type Default Value Platform
(indicator: string) => void - Both

onFocus

Callback that's called whenever the input is focused.

Type Default Value Platform
() => void - Both

onLinkDetected

  start: Int32;
  end: Int32;
}
  • text is the link's displayed text.
  • url is the underlying link's URL.
  • start is the starting index of the link.
  • end is the first index after the ending index of the link.

Payload interface contains all the useful mention data:

interface OnMentionDetected {
  text: string;
  indicator: string;
  attributes: Record<string, string>;
}
  • text is the mention's displayed text.
  • indicator is the indicator of the mention.
  • attributes are the additional user-defined attributes that are being stored with the mention.
Type Default Value Platform

Type Default Value Platform
View Style | Text Style - Both

ViewProps

The input inherits ViewProps, but keep in mind that some of the props may not be supported.

androidExperimentalSynchronousEvents - EXPERIMENTAL

If true, Android will use experimental synchronous events. This will prevent from input flickering when updating component size. However, this is an experimental feature, which has not been thoroughly tested. We may decide to enable it by default in a future release.

Type Default Value Platform
bool false Android

Ref Methods

All the methods should be called on the input's ref.

.blur()

blur: () => void;

Blurs the input.

.focus()

focus: () => void;

Focuses the input.

.getHTML()

getHTML: () => Promise<string>;

Returns a Promise that resolves with the current HTML content of the input. This is useful when you need to get the HTML on-demand (e.g., when saving) without the performance overhead of continuous HTML parsing via onChangeHtml.

.setImage()

setImage: (src: string, width: number, height: number) => void;

Sets the inline image at the current selection.

  • src: string - absolute path to a file or remote image address.
  • width: number - width of the image.
  • height: number - height of the image.

Note

It's developer responsibility to provide proper width and height, which may require calculating aspect ratio. Also, keep in mind that in case of providing incorrect image source, static placeholder will be displayed. We may consider adding automatic image size detection and improved error handling in future releases.

.setLink()

setLink: (
  start: number,
  end: number,
  text: string,
  url: string
) => void;

Sets the link at the given place with a given displayed text and URL. Link will replace any text if there was some between start and end indexes. Setting a link with start equal to end will just insert it in place.

  • start: number - the starting index where the link should be.
  • end: number - first index behind the new link's ending index.
  • text: string - displayed text of the link.
  • url: string - URL of the link.

.setMention()

setMention: (
  indicator: string,
  text: string,
  attributes?: Record<string, string>
) => void;

Sets the currently edited mention with a given indicator, displayed text and custom attributes.

  • indicator: string - the indicator of the set mention.
  • text: string - the text that should be displayed for the mention. Anything the user typed gets replaced by that text. The mention indicator isn't added to that text.
  • attributes?: Record<string, string> - additional, custom attributes for the mention that can be passed as a typescript record. They are properly preserved through parsing from and to the HTML format.

.setValue()

setValue: (value: string) => void;

Sets the input's value.

  • value: string - value to set, it can either be react-native-enriched supported HTML string or raw text.

.setSelection()

setSelection: (start: number, end: number) => void;

Sets the selection at the given indexes.

  • start: number - starting index of the selection.
  • end: number - first index after the selection's ending index. For just a cursor in place (no selection), start equals end.

.startMention()

startMention: (indicator: string) => void;

Starts a mention with the given indicator. It gets put at the cursor/selection.

  • indicator: string - the indicator that starts the new mention.

.toggleBlockQuote()
