Usage

Integration

The following code snippet illustrates how you can directly incorporate the Reactions component into your app.

App.tsx

import React from "react";
import { CometChat } from '@cometchat/chat-sdk-react-native';
import { CometChatMessages, CometChatReactions, ReactionsStyleInterface } from '@cometchat/chat-uikit-react-native';

function App(): React.JSX.Element {
    const [chatUser, setChatUser] = React.useState<CometChat.User| undefined>();
    const [message, setMessage] = React.useState<CometChat.TextMessage | undefined>(undefined);

    React.useEffect(() => {
        CometChat.getUser("uid").then((user) => {
           setChatUser(user);
        })
        CometChat.getMessageDetails(messageId).then((message: any) => {
           setMessage(message);
        });
    }, []);

    return (
     <>
         {message && <CometChatReactions
                        messageObject={message}
                      >
                     </CometChatReactions>}
     </>
   );
  }

Actions

Actions dictate how a component functions. They are divided into two types: Predefined and User-defined. You can override either type, allowing you to tailor the behavior of the component to fit your specific needs.

1. onReactionPress

ReactionPress is triggered when you press on each Reaction in the footer view of message bubble. You can override this action using the following code snippet.

onReactionPress = { onReactionPressHandler };

Example

In this example, we are employing the onReactionPress action.

App.tsx

App.tsx

import React from "react";
import { CometChat } from '@cometchat/chat-sdk-react-native';
import { CometChatMessages, CometChatReactions, ReactionsStyleInterface } from '@cometchat/chat-uikit-react-native';

function App(): React.JSX.Element {
    const [chatUser, setChatUser] = React.useState<CometChat.User| undefined>();
    const [message, setMessage] = React.useState<CometChat.TextMessage | undefined>(undefined);

    React.useEffect(() => {
        CometChat.getUser("uid").then((user) => {
           setChatUser(user);
        })
        CometChat.getMessageDetails(messageId).then((message: any) => {
           setMessage(message);
        });
    }, []);

    const reactionsStyle : ReactionsStyleInterface = {
       backgroundColor:'red',
       primaryBackgroundColor: "#b067f5",
       primaryBorder: {
         borderWidth: 2,
         borderStyle: 'solid',
         borderColor: 'red'
      }
    };

    const onReactionPressHandler = (reaction: CometChat.ReactionCount, messageObject: CometChat.BaseMessage) => {
       //code
    }

    return (
     <>
         {message && <CometChatReactions
                        messageObject={message}
                        style={reactionsStyle}
                        onReactionPress={onReactionPressHandler}>
                     </CometChatReactions>}
     </>
   );
  }

2. onReactionLongPress

ReactionLongPress is triggered when you press on each Reaction in the footer view of message bubble. You can override this action using the following code snippet.

onReactionLongPress = { onReactionLongPressHandler };

Example

In this example, we are employing the onReactionLongPress action.

App.tsx

App.tsx

import React from "react";
import { CometChat } from '@cometchat/chat-sdk-react-native';
import { CometChatMessages, CometChatReactions, ReactionsStyleInterface } from '@cometchat/chat-uikit-react-native';

function App(): React.JSX.Element {
    const [chatUser, setChatUser] = React.useState<CometChat.User| undefined>();
    const [message, setMessage] = React.useState<CometChat.TextMessage | undefined>(undefined);

    React.useEffect(() => {
        CometChat.getUser("uid").then((user) => {
           setChatUser(user);
        })
        CometChat.getMessageDetails(messageId).then((message: any) => {
           setMessage(message);
        });
    }, []);

    const reactionsStyle : ReactionsStyleInterface = {
       backgroundColor:'red',
       primaryBackgroundColor: "#b067f5",
       primaryBorder: {
         borderWidth: 2,
         borderStyle: 'solid',
         borderColor: 'red'
      }
    };

    const onReactionLongPressHandler = (reaction: CometChat.ReactionCount, messageObject: CometChat.BaseMessage) => {
       //long
    }

    return (
     <>
         {message && <CometChatReactions
                        messageObject={message}
                        style={reactionsStyle}
                        onReactionLongPress={onReactionLongPressHandler}
                        >
                     </CometChatReactions>}
     </>
   );
  }

Filters

Filters allow you to customize the data displayed in a list within a Component. You can filter the list based on your specific criteria, allowing for a more customized. Filters can be applied using RequestBuilders of Chat SDK.

The Reactions component does not have any exposed filters.

Events

Events are emitted by a Component. By using event you can extend existing functionality. Being global events, they can be applied in Multiple Locations and are capable of being Added or Removed.

The Reactions component does not produce any events.

Customization

To fit your app's design requirements, you can customize the appearance of the Reaction component. We provide exposed methods that allow you to modify the experience and behavior according to your specific needs.

Style

Using Style you can customize the look and feel of the component in your app, These parameters typically control elements such as the color, size, shape, and fonts used within the component.

1. reactionsStyle

To customize the appearance, you can assign a reactionsStyle object to the Reactions component.

Example

In this example, we are employing the reactionsStyle.

App.tsx

App.tsx

import React from "react";
import { CometChat } from '@cometchat/chat-sdk-react-native';
import { CometChatMessages, CometChatReactions, ReactionsStyleInterface } from '@cometchat/chat-uikit-react-native';

function App(): React.JSX.Element {
    const [chatUser, setChatUser] = React.useState<CometChat.User| undefined>();
    const [message, setMessage] = React.useState<CometChat.TextMessage | undefined>(undefined);

    React.useEffect(() => {
        CometChat.getUser("uid").then((user) => {
           setChatUser(user);
        })
        CometChat.getMessageDetails(messageId).then((message: any) => {
           setMessage(message);
        });
    }, []);

    const reactionsStyle : ReactionsStyleInterface = {
       backgroundColor:'red',
       primaryBackgroundColor: "#b067f5",
       primaryBorder: {
         borderWidth: 2,
         borderStyle: 'solid',
         borderColor: 'red'
      }
    };


    return (
     <>
         {message && <CometChatReactions
                        messageObject={message}
                        onReactionPress={onReactionPressHandler}>
                     </CometChatReactions>}
     </>
   );
  }
