Reactions

Overview

The CometChatReactions component provides a visual representation of emoji reactions associated with a specific message. It enables users to quickly identify which emojis were used to react to the message and by whom.

Usage

Integration

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

ReactionDemo.tsx
App.tsx

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { CometChatReactions, ReactionsStyle } from '@cometchat/chat-uikit-react'
import React from 'react'
import { createComponent } from "@lit-labs/react";

const ReactionDemo = () => {
    const [message, setmessage] = React.useState<CometChat.BaseMessage | undefined>();

    React.useEffect(() => {
        CometChat.getMessageDetails(message-id).then((message) => {
            setmessage(message);
        })
    }, []);

    const CometChatReaction = createComponent({
        tagName: "cometchat-reactions",
        elementClass: CometChatReactions,
        react: React,
      });
    const reactionsStyle = new ReactionsStyle({
        background:'#b067f5',
        border:'2px solid #881ced',
        borderRadius:'20px',
        width:'170px',
      });
    return (
        <>
            {
                message &&
                <CometChatReaction
                messageObject={message}
                reactionsStyle={reactionsStyle}
                />
            }
        </>
    )
}

export default ReactionDemo;

import { ReactionDemo } from "./ReactionDemo";

export default function App() {
  return (
    <div className="App">
      <div>
        <ReactionDemo />
      </div>
    </div>
  );
}

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. reactionClick

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

reactionClick = { onReactionClick };

Example

In this example, we are employing the reactionClick action.

TypeScript
JavaScript

ReactionDemo.tsx
import { CometChat } from '@cometchat/chat-sdk-javascript';
import { CometChatReactions, ReactionsStyle } from '@cometchat/chat-uikit-react'
import React from 'react'
import { createComponent } from "@lit-labs/react";

const ReactionDemo = () => {
    const [message, setMessage] = React.useState<CometChat.BaseMessage | undefined>();

    React.useEffect(() => {
        CometChat.getMessageDetails(message-id).then((message) => {
            setMessage(message);
        })
    }, []);

    const CometChatReaction = createComponent({
        tagName: "cometchat-reactions",
        elementClass: CometChatReactions,
        react: React,
      });
    function onReactionClick(reaction: CometChat.ReactionCount, message: CometChat.BaseMessage): void {
        console.log("Your Custom Reaction Click actions");
    }
    return (
        <>
            {
                message &&
                <CometChatReaction
                messageObject={message}
                reactionClick={onReactionClick}
                />
            }
        </>
    )
}

export default ReactionDemo;

ReactionDemo.jsx
import { CometChat } from "@cometchat/chat-sdk-javascript";
import {
  CometChatReactions,
  ReactionsStyle,
} from "@cometchat/chat-uikit-react";
import React, { useState, useEffect } from "react";
import { createComponent } from "@lit-labs/react";

const ReactionDemo = () => {
  const [message, setMessage] = useState();

  useEffect(() => {
    CometChat.getMessageDetails("message-id").then((message) => {
      setMessage(message);
    });
  }, []);

  const CometChatReaction = createComponent({
    tagName: "cometchat-reactions",
    elementClass: CometChatReactions,
    react: React,
  });

  function onReactionClick(reaction, message) {
    console.log("Your Custom Reaction Click actions");
  }

  return (
    <>
      {message && (
        <CometChatReaction
          messageObject={message}
          reactionClick={onReactionClick}
        />
      )}
    </>
  );
};

export default ReactionDemo;

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.

    const [message, setMessage] = React.useState<CometChat.BaseMessage | undefined>();

    React.useEffect(() => {
        CometChat.getMessageDetails(message-id).then((message) => {
            setMessage(message);
        })
    }, []);

    const CometChatReaction = createComponent({
        tagName: "cometchat-reactions",
        elementClass: CometChatReactions,
        react: React,
      });
    const reactionsStyle = new ReactionsStyle({
        background:'#b067f5',
        border:'2px solid #881ced',
        borderRadius:'20px',
        width:'170px',
      });
    return (
        <>
            {
                message &&
                <CometChatReaction
                messageObject={message}
                reactionsStyle={reactionsStyle}
                />
            }
        </>
    )
}

export default ReactionDemo;

    });
  }, []);

  const CometChatReaction = createComponent({

Configuration

Configurations offer the ability to customize the properties of each component within a Composite Component.

Reaction Info

If you want to customize the properties of the Reaction Info Component inside Reactions Component, you need use the reactionInfoConfiguration object.

TypeScript
JavaScript

ReactionDemo.tsx
import { CometChat } from '@cometchat/chat-sdk-javascript';
import { CometChatReactions, ReactionInfoConfiguration, ReactionInfoStyle } from '@cometchat/chat-uikit-react'
import React from 'react'
import { createComponent } from "@lit-labs/react";

const ReactionDemo = () => {
    const [message, setMessage] = React.useState<CometChat.BaseMessage | undefined>();

    React.useEffect(() => {
        CometChat.getMessageDetails(message-id).then((message) => {
            setMessage(message);
        })
    }, []);

    const CometChatReaction = createComponent({
        tagName: "cometchat-reactions",
        elementClass: CometChatReactions,
        react: React,
      });

    const reactionInfoStyle = new ReactionInfoStyle({
        background:'#631aeb',
        borderRadius:'20px'
    })
    const reactionInfoConfiguration = new ReactionInfoConfiguration({
        reactionInfoStyle:reactionInfoStyle
        //properties of reaction info
    });

    return (
        <>
            {
                message &&
                <CometChatReaction
                messageObject={message}
                reactionInfoConfiguration={reactionInfoConfiguration}
                />
            }
        </>
    )
}

export default ReactionDemo;

ReactionDemo.jsx
import { CometChat } from "@cometchat/chat-sdk-javascript";
import {
  CometChatReactions,
  ReactionInfoConfiguration,
  ReactionInfoStyle,
} from "@cometchat/chat-uikit-react";
import React, { useState, useEffect } from "react";
import { createComponent } from "@lit-labs/react";

const ReactionDemo = () => {
  const [message, setMessage] = useState();

  useEffect(() => {
    CometChat.getMessageDetails("message-id").then((message) => {
      setMessage(message);
    });
  }, []);

  const CometChatReaction = createComponent({
    tagName: "cometchat-reactions",
    elementClass: CometChatReactions,
    react: React,
  });

  const reactionInfoStyle = new ReactionInfoStyle({
    background: "#631aeb",
    borderRadius: "20px",
  });

  const reactionInfoConfiguration = new ReactionInfoConfiguration({
    reactionInfoStyle: reactionInfoStyle,
    // Add other properties of reaction info as needed
  });

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

export default ReactionDemo;

The reactionInfoConfiguration indeed provides access to all the Action, Filters, Styles, Functionality, and Advanced properties of the Reaction Info component.

In the above example, we are styling a few properties of the Reaction Info component using reactionInfoConfiguration.

Reaction List

If you want to customize the properties of the Reaction List Component inside Reactions Component, you need use the reactionListConfiguration object.

TypeScript
JavaScript

ReactionDemo.tsx
import { CometChat } from '@cometchat/chat-sdk-javascript';
import { CometChatReactions, ReactionListConfiguration, ReactionListStyle } from '@cometchat/chat-uikit-react'
import React from 'react'
import { createComponent } from "@lit-labs/react";

const ReactionDemo = () => {
    const [message, setMessage] = React.useState<CometChat.BaseMessage | undefined>();

    React.useEffect(() => {
        CometChat.getMessageDetails(message-id).then((message) => {
            setMessage(message);
        })
    }, []);

    const CometChatReaction = createComponent({
        tagName: "cometchat-reactions",
        elementClass: CometChatReactions,
        react: React,
      });

    const reactionListStyle = new ReactionListStyle({
        background:'#631aeb',
        border:'2px solid #881ced'
    })

    return (
        <>
            {
                message &&
                <CometChatReaction
                messageObject={message}
                reactionListConfiguration={new ReactionListConfiguration({
                    reactionListStyle: reactionListStyle
                    //properties of reaction list
                })}
                />
            }
        </>
    )
}

export default ReactionDemo;

ReactionDemo.jsx
import { CometChat } from "@cometchat/chat-sdk-javascript";
import {
  CometChatReactions,
  ReactionListConfiguration,
  ReactionListStyle,
} from "@cometchat/chat-uikit-react";
import React, { useState, useEffect } from "react";
import { createComponent } from "@lit-labs/react";

const ReactionDemo = () => {
  const [message, setMessage] = useState();

  useEffect(() => {
    CometChat.getMessageDetails("message-id").then((message) => {
      setMessage(message);
    });
  }, []);

  const CometChatReaction = createComponent({
    tagName: "cometchat-reactions",
    elementClass: CometChatReactions,
    react: React,
  });

  const reactionListStyle = new ReactionListStyle({
    background: "#631aeb",
    border: "2px solid #881ced",
  });

  return (
    <>
      {message && (
        <CometChatReaction
          messageObject={message}
          reactionListConfiguration={
            new ReactionListConfiguration({
              reactionListStyle: reactionListStyle,
              // Add other properties of reaction list as needed
            })
          }
        />
      )}
    </>
  );
};

export default ReactionDemo;

The reactionListConfiguration indeed provides access to all the Action, Filters, Styles, Functionality, and Advanced properties of the Reaction List component.

In the above example, we are styling a few properties of the Reaction List component using reactionListConfiguration.
