# Message List

> Message List — CometChat documentation.

## Overview

`MessageList` is a [Composite Component](/ui-kit/angular/components-overview#composite-components) that displays a list of messages and effectively manages real-time operations. It includes various types of messages such as Text Messages, Media Messages, Stickers, and more.

`MessageList` is primarily a list of the base component [MessageBubble](/ui-kit/angular/message-bubble). The MessageBubble Component is utilized to create different types of chat bubbles depending on the message type.

## Usage

### Integration

The following code snippet illustrates how you can directly incorporate the MessageList component into your Application.

<Tabs>
  <Tab title="app.module.ts">
    ```ts theme={null}
    import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from "@angular/core";
    import { BrowserModule } from "@angular/platform-browser";
    import { CometChatMessageList } from "@cometchat/chat-uikit-angular";
    import { AppComponent } from "./app.component";

    @NgModule({
      imports: [BrowserModule, CometChatMessageList],
      declarations: [AppComponent],
      providers: [],
      bootstrap: [AppComponent],
      schemas: [CUSTOM_ELEMENTS_SCHEMA],
    })
    export class AppModule {}
    ```
  </Tab>

    import { CometChat } from '@cometchat/chat-sdk-javascript';
    import { Component, OnInit } from '@angular/core';
    import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
    import "@cometchat/uikit-elements";

    @Component({
      selector: 'app-root',
      templateUrl: './app.component.html',
      styleUrls: ['./app.component.css']
    })
    export class AppComponent implements OnInit{
      ngOnInit(): void {
        CometChat.getUser("uid").then((user:CometChat.User)=>{
          this.userObject=user;
        });
      }

      public userObject!: CometChat.User;

      constructor(private themeService:CometChatThemeService) {
        themeService.theme.palette.setMode("light")
        themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
      }

      onLogin(UID?: any) {
        CometChatUIKit.login({ uid: UID }).then(
          (user) => {
            setTimeout(() => {
              window.location.reload();
            }, 1000);
          },
          (error) => {

### 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. onThreadRepliesClick

`onThreadRepliesClick` is triggered when you click on the threaded message bubble. The `onThreadRepliesClick` action doesn't have a predefined behavior. You can override this action using the following code snippet.

<Tabs>
  <Tab title="app.component.ts">
    ```ts theme={null}
    import { Component, OnInit } from '@angular/core';
    import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
    import "@cometchat/uikit-elements";

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

      ngOnInit(): void {
        CometChat.getUser("uid").then((user:CometChat.User)=>{
          this.userObject=user;
        });
      }

      public userObject!: CometChat.User;

      constructor(private themeService:CometChatThemeService) {
        themeService.theme.palette.setMode("light")
        themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
      }

      public handleOnThreadRepliesClick = ()=>{
        console.log("your custom on thread replies click");
      };

      onLogin(UID?: any) {
        CometChatUIKit.login({ uid: UID }).then(
          (user) => {
            setTimeout(() => {
              window.location.reload();
            }, 1000);
          },
          (error) => {
            console.log("Login failed with exception:", { error });
          }
        );
      }
    }
    ```
  </Tab>

  <Tab title="app.component.html">
    ```html theme={null}
    <div class="fullwidth">
      <cometchat-message-list
        *ngIf="userObject"
        [user]="userObject"
        [onThreadRepliesClick]="handleOnThreadRepliesClick"
      ></cometchat-message-list>
    </div>
    ```
  </Tab>
</Tabs>

##### 2. onError

This action doesn't change the behavior of the component but rather listens for any errors that occur in the MessageList component.

<Tabs>
  <Tab title="app.component.ts">
    ```ts theme={null}
    import { CometChat } from '@cometchat/chat-sdk-javascript';
    import { Component, OnInit } from '@angular/core';

    import "@cometchat/uikit-elements";

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

      ngOnInit(): void {
        CometChat.getUser("uid").then((user:CometChat.User)=>{
          this.userObject=user;
        });
      }

      public userObject!: CometChat.User;

      constructor(private themeService:CometChatThemeService) {
        themeService.theme.palette.setMode("light")
        themeService.theme.palette.setPrimary({ light: "#6851D6", dark: "#6851D6" })
      }

      public handleOnError = (error: CometChat.CometChatException) => {
        console.log("your custom on error action", error);
      };

      onLogin(UID?: any) {
        CometChatUIKit.login({ uid: UID }).then(
          (user) => {
            setTimeout(() => {
              window.location.reload();
            }, 1000);
          },
          (error) => {
            console.log("Login failed with exception:", { error });
          }
        );
      }
    }
    ```
  </Tab>

  <Tab title="app.component.html">
    ```html theme={null}
    <div class="fullwidth">
      <cometchat-message-list
        *ngIf="userObject"

### Filters

You can adjust the `MessagesRequestBuilder` in the MessageList Component to customize your message list. Numerous options are available to alter the builder to meet your specific needs. For additional details on `MessagesRequestBuilder`, please visit [MessagesRequestBuilder](/sdk/javascript/message-filtering).

In the example below, we are applying a filter to the messages based on a search substring and for a specific user. This means that only messages that contain the search term and are associated with the specified user will be displayed

          (user) => {
            setTimeout(() => {
              window.location.reload();
            }, 1000);
          },

  The following parameters in messageRequestBuilder will always be altered inside the message list

  1. UID
  2. GUID
</Note>

### 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 list of events emitted by the Message List component is as follows.

| Event                   | Description                                                                                                                                     |
| ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| **ccOpenChat**          | this event alerts the listeners if the logged-in user has opened a user or a group chat                                                         |
| **ccMessageEdited**     | Triggers whenever a loggedIn user edits any message from the list of messages .it will have three states such as: inProgress, success and error |
| **ccMessageDeleted**    | Triggers whenever a loggedIn user deletes any message from the list of messages                                                                 |
| **ccActiveChatChanged** | This event is triggered when the user navigates to a particular chat window.                                                                    |

### Advance

For advanced-level customization, you can set custom views to the component. This lets you tailor each aspect of the component to fit your exact needs and application aesthetics. You can create and define your views, layouts, and UI elements and then incorporate those into the component.

#### Templates

[CometChatMessageTemplate](/ui-kit/angular/message-template) is a pre-defined structure for creating message views that can be used as a starting point or blueprint for creating message views often known as message bubbles. For more information, you can refer to [CometChatMessageTemplate](/ui-kit/angular/message-template).

You can set message Templates to MessageList by using the following code snippet

#### DateSeparatorPattern

You can customize the date pattern of the message list separator using the `DateSeparatorPattern` prop. Choose from predefined options like time, DayDate, DayDateTime, or DateTime.

## Configuration

[Configurations](/ui-kit/angular/components-overview#configurations) offer the ability to customize the properties of each component within a Composite Component.

### MessageInformation

From the MessageList, you can navigate to the [MesssageInformation](/ui-kit/angular/message-information) component as shown in the image.

<Frame>
  <img src="https://mintcdn.com/cometchat-22654f5b-docs-rn-guide-message-privately/ugckbRl5Q-H7t8X2/images/e56d245b-message_list_message_information_option_web_screens-9da12131fd0f5fc7b7a07ec647c9c63b.png?fit=max&auto=format&n=ugckbRl5Q-H7t8X2&q=85&s=9bd110277f444564d8255de67bbee574" width="3600" height="2400" data-path="images/e56d245b-message_list_message_information_option_web_screens-9da12131fd0f5fc7b7a07ec647c9c63b.png" />

If you wish to modify the properties of the [MesssageInformation](/ui-kit/angular/message-information) Component, you can use the `MessageInformationConfiguration` object.

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

      onLogin(UID?: any) {
        CometChatUIKit.login({ uid: UID }).then(
          (user) => {
            setTimeout(() => {
              window.location.reload();
            }, 1000);
          },
          (error) => {

  </Tab>
</Tabs>

The `MessageInformationConfiguration` indeed provides access to all the [Action](/ui-kit/angular/message-information#actions), [Filters](/ui-kit/angular/message-information#filters), [Styles](/ui-kit/angular/message-information#style), [Functionality](/ui-kit/angular/message-information#functionality), and [Advanced](/ui-kit/angular/message-information#functionality) properties of the [MesssageInformation](/ui-kit/angular/message-information) component.

Please note that the Properties marked with the 🛑 symbol are not accessible within the Configuration Object.

**Example**

**Default**

In the above example, we are styling a few properties of the [MesssageInformation](/ui-kit/angular/message-information) component using `MessageInformationConfiguration`.

### Reaction

If you wish to modify the properties of the [Reaction](/ui-kit/angular/reaction) Component, you can use the `reactionsConfiguration` object.
