# Reactions

> Reactions — CometChat documentation.

## 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.

### Actions

[Actions](/ui-kit/angular/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.

##### 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.

**Example**

In this example, we are employing the `reactionClick` action.

  <Tab title="app.component.ts">

    import "@cometchat/uikit-elements";

    @Component({
      selector: 'app-root',
      templateUrl: './app.component.html',
      styleUrls: ['./app.component.css']
    })
    export class AppComponent {

      constructor(private themeService:CometChatThemeService) {

        }).catch((error) => {
          console.error('Error fetching message details:', error);
        });
      }
      public handleOnReactionClick = (reaction: CometChat.ReactionCount, message: CometChat.BaseMessage): void  =>{
        console.log("your custom on reaction click actions");
      };
      onLogin(UID?: any) {
        CometChatUIKit.login({ uid: UID }).then(
          (user) => {
            setTimeout(() => {
              window.location.reload();
            }, 1000);
          },
          (error) => {
            console.log("Login failed with exception:", { error });
          }
        );

      ></cometchat-reactions>
    </div>
    ```

### 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](/ui-kit/angular/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` 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`.

## Configuration

[Configurations](/ui-kit/angular/components-overview#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](/ui-kit/angular/reaction-info) Component inside Reactions Component, you need use the `reactionInfoConfiguration` object.

The `reactionInfoConfiguration` indeed provides access to all the [Action](/ui-kit/angular/reaction-info#actions), [Filters](/ui-kit/angular/reaction-info#filters), [Styles](/ui-kit/angular/reaction-info#style), [Functionality](/ui-kit/angular/reaction-info#functionality), and [Advanced](/ui-kit/angular/reaction-info#functionality) properties of the [Reaction Info](/ui-kit/angular/reaction-info) component.

In the above example, we are styling a few properties of the [Reaction Info](/ui-kit/angular/reaction-info) component using `reactionInfoConfiguration`.

### Reaction List

If you want to customize the properties of the [Reaction List](/ui-kit/angular/reaction-list) Component inside Reactions Component, you need use the `reactionListConfiguration` object.

The `reactionListConfiguration` indeed provides access to all the [Action](/ui-kit/angular/reaction-list#actions), [Filters](/ui-kit/angular/reaction-list#filters), [Styles](/ui-kit/angular/reaction-list#style), [Functionality](/ui-kit/angular/reaction-list#functionality), and [Advanced](/ui-kit/angular/reaction-list#functionality) properties of the [Reaction List](/ui-kit/angular/reaction-list) component.

In the above example, we are styling a few properties of the [Reaction List](/ui-kit/angular/reaction-list) component using `reactionListConfiguration`.
