**`messages`** _(Array)_ - Messages to display - **`user`** _(Object)_ - User sending the messages: `{ _id, name, avatar }` - **`onSend`** _(Function)_ - Callback when sending a message - **`messageIdGenerator`** _(Function)_ - Generate an id for new messages. Defaults to a simple random string generator. - **`locale`** _(String)_ - Locale to localize the dates. You need first to import the locale you need (ie. `require('dayjs/locale/de')` or `import 'dayjs/locale/fr'`) - **`colorScheme`** _('light' | 'dark')_ - Force color scheme (light/dark mode). When set to `'light'` or `'dark'`, it overrides the system color scheme. When `undefined`, it uses the system color scheme. Default is `undefined`. ### Refs - **`messagesContainerRef`** _(FlatList ref)_ - Ref to the flatlist - **`textInputRef`** _(TextInput ref)_ - Ref to the text input ### Keyboard & Layout - **`keyboardProviderProps`** _(Object)_ - Props to be passed to the [`KeyboardProvider`](https://kirillzyusko.github.io/react-native-keyboard-controller/docs/api/keyboard-provider) for keyboard handling. Default values: - `statusBarTranslucent: true` - Required on Android for correct keyboard height calculation when status bar is translucent (edge-to-edge mode) - `navigationBarTranslucent: true` - Required on Android for correct keyboard height calculation when navigation bar is translucent (edge-to-edge mode) - **`keyboardAvoidingViewProps`** _(Object)_ - Props to be passed to the [`KeyboardAvoidingView`](https://kirillzyusko.github.io/react-native-keyboard-controller/docs/api/components/keyboard-avoiding-view). See **keyboardVerticalOffset** below for proper keyboard handling. - **`isAlignedTop`** _(Boolean)_ Controls whether or not the message bubbles appear at the top of the chat (Default is false - bubbles align to bottom) - **`isInverted`** _(Bool)_ - Reverses display order of `messages`; default is `true` #### Understanding `keyboardVerticalOffset` The [`keyboardVerticalOffset`](https://kirillzyusko.github.io/react-native-keyboard-controller/docs/api/components/keyboard-avoiding-view#keyboardverticaloffset) tells the KeyboardAvoidingView where its container starts relative to the top of the screen. This is essential when GiftedChat is not positioned at the very top of the screen (e.g., when you have a navigation header). **Default value:** `insets.top` (status bar height from `useSafeAreaInsets()`). This works correctly only when GiftedChat fills the entire screen without a navigation header. If you have a navigation header, you need to pass the correct offset via `keyboardAvoidingViewProps`. **What the value means:** The offset equals the distance (in points) from the top of the screen to the top of your GiftedChat container. This typically includes: - Status bar height - Navigation header height (on iOS, `useHeaderHeight()` already includes status bar) **How to use:** ```jsx import { useHeaderHeight } from '@react-navigation/elements' function ChatScreen() { // useHeaderHeight() returns status bar + navigation header height on iOS const headerHeight = useHeaderHeight() return ( <GiftedChat keyboardAvoidingViewProps={{ keyboardVerticalOffset: headerHeight }} // ... other props /> ) } ``` > **Note:** `useHeaderHeight()` requires your chat component to be rendered inside a proper navigation screen (not conditional rendering). If it returns `0`, ensure your chat screen is a real navigation screen with a visible header. **Why this matters:** Without the correct offset, the keyboard may overlap the input field or leave extra space. The KeyboardAvoidingView uses this value to calculate how much to shift the content when the keyboard appears. ### Text Input & Composer - **`text`** _(String)_ - Input text; default is `undefined`, but if specified, it will override GiftedChat's internal state. Useful for managing text state outside of GiftedChat (e.g. with Redux). Don't forget to implement `textInputProps.onChangeText` to update the text state. - **`initialText`** _(String)_ - Initial text to display in the input field - **`isSendButtonAlwaysVisible`** _(Bool)_ - Always show send button in input text composer; default `false`, show only when text input is not empty - **`isTextOptional`** _(Bool)_ - Allow sending messages without text (useful for media-only messages); default `false`. Use with `isSendButtonAlwaysVisible` for media attachments. - **`minComposerHeight`** _(Object)_ - Custom min-height of the composer. - **`maxComposerHeight`** _(Object)_ - Custom max height of the composer. - **`minInputToolbarHeight`** _(Integer)_ - Minimum height of the input toolbar; default is `44` - **`renderInputToolbar`** _(Component | Function)_ - Custom message composer container - **`renderComposer`** _(Component | Function)_ - Custom text input message composer - **`renderSend`** _(Component | Function)_ - Custom send button; you can pass children to the original `Send` component quite easily, for example, to use a custom icon ([example](https://github.com/FaridSafi/react-native-gifted-chat/pull/487)) - **`renderActions`** _(Component | Function)_ - Custom action button on the left of the message composer - **`renderAccessory`** _(Component | Function)_ - Custom second line of actions below the message composer - **`textInputProps`** _(Object)_ - props to be passed to the [`<TextInput>`](https://reactnative.dev/docs/textinput). ### Actions & Action Sheet - **`onPressActionButton`** _(Function)_ - Callback when the Action button is pressed (if set, the default `actionSheet` will not be used) - **`actionSheet`** _(Function)_ - Custom action sheet interface for showing action options - **`actions`** _(Array)_ - Custom action options for the input toolbar action button; array of objects with `title` (string) and `action` (function) properties - **`actionSheetOptionTintColor`** _(String)_ - Tint color for action sheet options ### Messages & Message Container - **`messagesContainerStyle`** _(Object)_ - Custom style for the messages container - **`renderMessage`** _(Component | Function)_ - Custom message container - **`renderLoading`** _(Component | Function)_ - Render a loading view when initializing - **`renderChatEmpty`** _(Component | Function)_ - Custom component to render in the ListView when messages are empty - **`renderChatFooter`** _(Component | Function)_ - Custom component to render below the MessagesContainer (separate from the ListView) - **`listProps`** _(Object)_ - Extra props to be passed to the messages [`<FlatList>`](https://reactnative.dev/docs/flatlist). Supports all FlatList props including `maintainVisibleContentPosition` for keeping scroll position when new messages arrive (useful for AI chatbots). ### Message Bubbles & Content - **`renderBubble`** _(Component | Function(`props: BubbleProps`))_ - Custom message bubble.

When enabled, users can swipe on a message to reply to it, displaying a reply preview in the input toolbar and the replied message above the new message bubble. > **Note:** This feature uses `ReanimatedSwipeable` from `react-native-gesture-handler` and `react-native-reanimated` for smooth, performant animations. #### Basic Usage ```tsx <GiftedChat messages={messages} onSend={onSend} user={{ _id: 1 }} reply={{ swipe: { isEnabled: true, direction: 'left', // swipe left to reply }, }} /> ``` #### Reply Props (Grouped) The `reply` prop accepts an object with the following structure: ```typescript interface ReplyProps<TMessage> { // Swipe gesture configuration swipe?: { isEnabled?: boolean // Enable swipe-to-reply; default false direction?: 'left' | 'right' // Swipe direction; default 'left' onSwipe?: (message: TMessage) => void // Callback when swiped renderAction?: ( // Custom swipe action component progress: SharedValue<number>, translation: SharedValue<number>, position: 'left' | 'right' ) => React.ReactNode actionContainerStyle?: StyleProp<ViewStyle> } // Reply preview styling (above input toolbar) previewStyle?: { containerStyle?: StyleProp<ViewStyle> textStyle?: StyleProp<TextStyle> imageStyle?: StyleProp<ImageStyle> } // In-bubble reply styling messageStyle?: { containerStyle?: StyleProp<ViewStyle> containerStyleLeft?: StyleProp<ViewStyle> containerStyleRight?: StyleProp<ViewStyle> textStyle?: StyleProp<TextStyle> textStyleLeft?: StyleProp<TextStyle> textStyleRight?: StyleProp<TextStyle> imageStyle?: StyleProp<ImageStyle> } // Callbacks and state message?: ReplyMessage // Controlled reply state onClear?: () => void // Called when reply cleared onPress?: (message: TMessage) => void // Called when reply preview tapped // Custom renderers renderPreview?: (props: ReplyPreviewProps) => React.ReactNode renderMessageReply?: (props: MessageReplyProps) => React.ReactNode } ``` #### ReplyMessage Structure When a message has a reply, it includes a `replyMessage` property: ```typescript interface ReplyMessage { _id: string | number text: string user: User image?: string audio?: string } ``` #### Advanced Example with External State ```tsx const [replyMessage, setReplyMessage] = useState<ReplyMessage | null>(null) <GiftedChat messages={messages} onSend={messages => { const newMessages = messages.map(msg => ({ ...msg, replyMessage: replyMessage || undefined, })) setMessages(prev => GiftedChat.append(prev, newMessages)) setReplyMessage(null) }} user={{ _id: 1 }} reply={{ swipe: { isEnabled: true, direction: 'right', onSwipe: setReplyMessage, }, message: replyMessage, onClear: () => setReplyMessage(null), onPress: (msg) => scrollToMessage(msg._id), }} /> ``` #### Smooth Animations The reply preview automatically animates when: - **Appearing**: Smoothly expands from zero height with fade-in effect - **Disappearing**: Smoothly collapses with fade-out effect - **Content changes**: Smoothly transitions when replying to a different message These animations use `react-native-reanimated` for 60fps performance. ### Scroll to Bottom - **`isScrollToBottomEnabled`** _(Bool)_ - Enables the scroll to bottom Component (Default is false) - **`scrollToBottomComponent`** _(Function)_ - Custom Scroll To Bottom Component container - **`scrollToBottomOffset`** _(Integer)_ - Custom Height Offset upon which to begin showing Scroll To Bottom Component (Default is 200) - **`scrollToBottomStyle`** _(Object)_ - Custom style for Scroll To Bottom wrapper (position, bottom, right, etc.) - **`scrollToBottomContentStyle`** _(Object)_ - Custom style for Scroll To Bottom content (size, background, shadow, etc.) ### Maintaining Scroll Position (AI Chatbots) For AI chat interfaces where long responses arrive and you don't want to disrupt the user's reading position, use [`maintainVisibleContentPosition`](https://reactnative.dev/docs/scrollview#maintainvisiblecontentposition) via `listProps`: ```tsx // Basic usage - always maintain scroll position <GiftedChat listProps={{ maintainVisibleContentPosition: { minIndexForVisible: 0, }, }} /> // With auto-scroll threshold - auto-scroll if within 10 pixels of newest content <GiftedChat listProps={{ maintainVisibleContentPosition: { minIndexForVisible: 0, autoscrollToTopThreshold: 10, }, }} /> // Conditionally enable based on scroll state (recommended for chatbots) const [isScrolledUp, setIsScrolledUp] = useState(false) <GiftedChat listProps={{ onScroll: (event) => { setIsScrolledUp(event.contentOffset.y > 50) }, maintainVisibleContentPosition: isScrolledUp ? { minIndexForVisible: 0, autoscrollToTopThreshold: 10 } : undefined, }} /> ``` --- ## 📱 Platform Notes ### Android <details> <summary>Keyboard configuration</summary> If you are using Create React Native App / Expo, no Android specific installation steps are required. Otherwise, we recommend modifying your project configuration: Make sure you have `android:windowSoftInputMode="adjustResize"` in your `AndroidManifest.xml`: ```xml <activity android:name=".MainActivity" android:label="@string/app_name" android:windowSoftInputMode="adjustResize" android:configChanges="keyboard|keyboardHidden|orientation|screenSize"> ``` For **Expo**, you can append `KeyboardAvoidingView` after GiftedChat (Android only): ```jsx <View style={{ flex: 1 }}> <GiftedChat /> {Platform.OS === 'android' && <KeyboardAvoidingView behavior="padding" />} </View> ``` </details> ### Web (react-native-web) <details> <summary>With create-react-app</summary> 1. Install react-app-rewired: `yarn add -D react-app-rewired` 2. Create `config-overrides.js`: ```js module.exports = function override(config, env) { config.module.rules.push({ test: /\.js$/, exclude: /node_modules[/\\](?!react-native-gifted-chat)/, use: { loader: 'babel-loader', options: { babelrc: false, configFile: false, presets: [ ['@babel/preset-env', { useBuiltIns: 'usage' }], '@babel/preset-react', ], plugins: ['@babel/plugin-proposal-class-properties'], }, }, }) return config } ``` > **Examples:** > - [xcarpentier/gifted-chat-web-demo](https://github.com/xcarpentier/gifted-chat-web-demo) > - [Gatsby example](https://github.com/xcarpentier/clean-archi-boilerplate/tree/develop/apps/web) </details> --- ## 🧪 Testing <details> <summary>Triggering layout events in tests</summary> `TEST_ID` is exported as constants that can be used in your testing library of choice. Gifted Chat uses `onLayout` to determine the height of the chat container. To trigger `onLayout` during your tests: ```typescript const WIDTH = 200 const HEIGHT = 2000 const loadingWrapper = getByTestId(TEST_ID.LOADING_WRAPPER) fireEvent(loadingWrapper, 'layout', { nativeEvent: { layout: { width: WIDTH, height: HEIGHT, }, }, }) ``` </details> --- ## 📦 Example App The repository includes a comprehensive example app demonstrating all features: ```bash # Clone and install git clone https://github.com/FaridSafi/react-native-gifted-chat.git cd react-native-gifted-chat/example yarn install # Run on iOS npx expo run:ios # Run on Android npx expo run:android # Run on Web npx expo start --web ``` The example app showcases: - 💬 Basic chat functionality - 🎨 Custom message bubbles and avatars - ↩️ Reply to messages with swipe gesture - ⚡ Quick replies (bot-style) - ✍️ Typing indicators - 📎 Attachment actions - 🔗 Link parsing and custom matchers - 🌐 Web compatibility --- ## ❓ Troubleshooting <details> <summary>TextInput is hidden on Android</summary> Make sure you have `android:windowSoftInputMode="adjustResize"` in your `AndroidManifest.xml`.
