## Usage

### Integration

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

<Tabs>
  <Tab title="ReactionInfoDemo.tsx">
    ```typescript theme={null}
    import { CometChat } from '@cometchat/chat-sdk-javascript';
    import { CometChatReactionInfo, ReactionInfoStyle } from '@cometchat/chat-uikit-react'
    import React from 'react'
    import { createComponent } from "@lit-labs/react";

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

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

        const ReactionInfo = createComponent({
            tagName: "cometchat-reaction-info",
            elementClass: CometChatReactionInfo,
            react: React,
          });

        const reactionInfoStyle = new ReactionInfoStyle({
            background:'#631aeb',
            borderRadius:'20px',
            width:'200px',
        })
        return (
            <>
                {
                    message &&
                    <div style={{marginTop:'500px', marginLeft:'300px'}}>
                        <ReactionInfo
                        messageObject={message}
                        reaction={"\ud83c\udfc8"}
                        reactionInfoStyle={reactionInfoStyle}
                        />
                    </div>
                }
            </>
        )
    }

    export default ReactionInfoDemo;
    ```
  </Tab>

  <Tab title="App.tsx">
    ```typescript theme={null}
    import { ReactionInfoDemo } from "./ReactionInfoDemo";

    export default function App() {
      return (
        <div className="App">
          <div>
            <ReactionInfoDemo />
          </div>
        </div>
      );
    }
    ```
  </Tab>
</Tabs>

### Actions

[Actions](/ui-kit/react/v4/components-overview#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.

The `Reactions Info` component does not have any exposed actions.

### 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.

You can adjust the `ReactionsRequestBuilder` in the Reaction Info Component to customize your Reaction info. Numerous options are available to alter the builder to meet your specific needs. For additional details on `ReactionsRequestBuilder`, please visit [ReactionsRequestBuilder](/sdk/javascript/reactions).

In the example below, we demonstrate the application of a filter to the `reactions info`. This filter allows you to specify a limit on the number of users displayed who have reacted with the same emoji.

    import React from 'react'

    }

    export default ReactionInfoDemo;
    ```
  </Tab>
</Tabs>

### Events

[Events](/ui-kit/react/v4/components-overview#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 Info` component does not produce any events.

## Customization

To fit your app's design requirements, you can customize the appearance of the Reaction Info 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. reactionInfoStyle

To customize the appearance, you can assign a `reactionInfoStyle` object to the `Reactions Info` component.

**Example**

In this example, we are employing the `reactionInfoStyle`.
