Conversations with Messages

Overview

The ConversationsWithMessages is a Composite Component encompassing components such as Conversations, Messages, and Contacts. Each of these component contributes to the functionality and structure of the overall ConversationsWithMessages component.

Components	Description
Conversations	The Conversations component is designed to display a list of either User or Group. This essentially represents your recent conversation history.
Messages	The Messages component is designed to manage the messaging interaction for either individual User or Group conversations.
Contacts	The CometChatContacts component is specifically designed to facilitate the display and management of both User and Groups.

Usage

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.

While the ConversationsWithMessages component does not have its actions, its components - Conversation, Messages, and Contacts - each have their own set of actions.

The Action of the components can be overridden through the use of the Configurations object of its components. Here is an example code snippet.

app.component.ts

import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import { ContactsConfiguration, ConversationsConfiguration } from '@cometchat/uikit-shared';
import "@cometchat/uikit-elements";

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

  public handleOnError = (error: CometChat.CometChatException) => {
   //your custom on error actions
  };
  public handleOnClose = () =>{
    //your custom on close actions
  };
  public conversationsConfigurations = new ConversationsConfiguration({
    onError:this.handleOnError,
  });
  public startConversationConfiguration = new ContactsConfiguration({
    onClose: this.handleOnClose
  });

  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) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

app.component.html

<div class="fullwidth">
  <cometchat-conversations-with-messages
    [StartConversationConfiguration]="startConversationConfiguration"
    [conversationConfiguration]="conversationsConfigurations"
  >
  </cometchat-conversations-with-messages>
</div>

---

The ConversationsWithMessages component overrides several actions from its components to reach its default behavior. The list of actions overridden by ConversationsWithMessages includes:

• OnItemClick : By overriding the OnItemClick of the Conversation Component, ConversationsWithMessages achieves navigation from Conversation to Messages component.

  

Fliters

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.

While the ConversationsWithMessages component does not have filters, its components do, For more detail on individual filters of its component refer to Conversations Filters and Messages Filters.

By utilizing the Configurations object of its components, you can apply filters.

In the following example, we're filtering Conversation to only show User

app.component.ts

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

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

  public conversationsConfigurations = new ConversationsConfiguration({
    conversationsRequestBuilder: new CometChat.ConversationsRequestBuilder().setConversationType('user').setLimit(10),
  });

  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) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

app.component.html

<div class="fullwidth">
  <cometchat-conversations-with-messages
    [conversationConfiguration]="conversationsConfigurations"
  >
  </cometchat-conversations-with-messages>
</div>

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 ConversationsWithMessages does not generate its events but its component does. For a full list of these events, you can refer to Conversations events and Messages events.

In the following example, we're incorporating observers for the ConversationDeleted event of Conversations and the MessageSent event of the Messages component.

Add Listener

public ccConversationDeleted!: Subscription;
public ccMessageSent!: Subscription;

ngOnInit(): void {
this.ccConversationDeleted =
CometChatConversationEvents.ccConversationDeleted.subscribe((conversation: CometChat.Conversation) => {
//your code
})

this.ccMessageSent =
CometChatMessageEvents.ccMessageSent.subscribe((obj: IMessages) => {
//your code
})
}

---

Remove Listener

ngOnDestroy(): void {
this.ccConversationDeleted?.unsubscribe();
this.ccMessageSent?.unsubscribe();
}

---

Customization

To fit your app's design requirements, you have the ability to customize the appearance of the ConversationsWithMessages 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. ConversationsWithMessages component doesn't have its own style parameters. But you can customize its component styles. For more details on individual component styles, you can refer Conversation Styles, Messages Styles, and Contacts Styles

Styles can be applied to SubComponents using their respective configurations.

Example

app.component.ts

import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import { ConversationsStyle, ConversationsConfiguration } from '@cometchat/uikit-shared';

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

  public conversationsStyle:ConversationsStyle = new ConversationsStyle({
    width:'100%',
    height:'100%',
    border:'1px solid #ee7752',
    background:'linear-gradient(#ee7752, #e73c7e, #23a6d5, #23d5ab)'
  });

  public conversationsConfigurations = new ConversationsConfiguration({
    conversationsStyle:this.conversationsStyle,
  });

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

Functionality

These are a set of small functional customizations that allow you to fine-tune the overall experience of the component. With these, you can change text, set custom icons, and toggle the visibility of UI elements.

user

you can utilize the user method with a User object as input to the ConversationsWithMessages component. This will automatically direct you to the Messages component for the specified User.

app.component.ts

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{

  public userObject!: CometChat.User;

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

Advanced

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 own views, layouts, and UI elements and then incorporate those into the component.

By utilizing the Configuration object of each component, you can apply advanced-level customizations to the ConversationsWithMessages.

Example

app.component.ts

import { Component, OnInit, ViewChild, TemplateRef } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import { ConversationsConfiguration } from '@cometchat/uikit-shared';
import "@cometchat/uikit-elements";

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

  @ViewChild('subtitleTemplate', { static: true }) subtitleTemplate!: TemplateRef<any>;
  public conversationsConfigurations!: ConversationsConfiguration;

  ngOnInit() {
    this.conversationsConfigurations = new ConversationsConfiguration({
      subtitleView:this.subtitleTemplate
    });
  };

  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) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

app.component.html

<div class="fullwidth">
  <cometchat-conversations-with-messages
    [conversationConfiguration]="conversationsConfigurations"
  >
  </cometchat-conversations-with-messages>
</div>

<ng-template #subtitleTemplate>
  <div
    style="display: flex; align-items: left; padding: 10px; font-size: 10px;"
  >
    Your Custom Subtitle View
  </div>
</ng-template>

To find all the details on individual Component advance customization you can refer, Conversations Advance,Messages Advance and Contacts Advance

ConversationsWithMessages uses advanced-level customization of both Conversation & Messages components to achieve its default behavior.

1. ConversationsWithMessages utilizes the menu of the Conversations subcomponent to navigate the user from Conversations to Contacts

   

2. ConversationsWithMessages utilizes the menu of the Messages subcomponent to navigate from Messages to Details

   

warning

When you override menu, the default behavior of ConversationsWithMessages will also be overridden.

Configurations

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

ConversationsWithMessages has Conversations, Messages, and Contacts component. Hence, each of these components will have its individual `Configuration``.

• Configurations expose properties that are available in its individual components.

Conversations

You can customize the properties of the Conversations component by making use of the conversationsConfiguration. You can accomplish this by employing the conversationsConfiguration props as demonstrated below:

TypeScript

 public conversationsConfigurations = new ConversationsConfiguration({
//override properties of conversations
 });

All exposed properties of ConversationsConfiguration can be found under Conversations. Properties marked with the report symbol are not accessible within the Configuration Object.

Example

Let's say you want to change the style of the Conversations subcomponent and, in addition, you only want to display users in the conversation list.

You can modify the style using the conversationsStyle property and filter the list with the conversationsRequestBuilder property.

app.component.ts

import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import {ConversationsStyle, ConversationsConfiguration } from '@cometchat/uikit-shared';
import "@cometchat/uikit-elements";

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

  public conversationsConfigurations = new ConversationsConfiguration({
    conversationsStyle: new ConversationsStyle({
      width: "100%",
      height: "100%",
      border: "1px solid #ee7752",
      background: "linear-gradient(#ee7752, #e73c7e, #23a6d5, #23d5ab)",
    }),
    conversationsRequestBuilder: new CometChat.ConversationsRequestBuilder().setConversationType('user').setLimit(5),
  });

  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) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

Messages

You can customize the properties of the Messages component by making use of the messagesConfiguration. You can accomplish this by employing the messagesConfiguration props as demonstrated below:

TypeScript

 public messagesConfiguration = new MessagesConfiguration({
//override properties of messages
 });

All exposed properties of MessagesConfiguration can be found under Messages. Properties marked with the report symbol are not accessible within the Configuration Object.

Example

Let's say you want to change the style of the Messages subcomponent and, in addition, you only want to hide message header.

You can modify the style using the messagesStyle property and hide the message header with the hideMessageHeader property.

app.component.ts

import { Component, OnInit } from '@angular/core';
import {  CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import { MessagesConfiguration, MessagesStyle } from '@cometchat/uikit-shared';
import "@cometchat/uikit-elements";

export class AppComponent implements OnInit{

  public messagesConfiguration = new MessagesConfiguration({
    hideMessageHeader:true,
    messagesStyle: new MessagesStyle({
      width: "100%",
      height: "100%",
      border: "1px solid #ee7752",
      background: "linear-gradient(#ee7752, #e73c7e, #23a6d5, #23d5ab)",
      messageTextColor: "yellow",
    }),
  });

Contacts

You can customize the properties of the Contacts component by making use of the ContactsConfiguration. You can accomplish this by employing the StartConversationConfiguration property as demonstrated below:

TypeScript

public startConversationConfiguration = new ContactsConfiguration({
//override properties of contacts
 });

All exposed properties of ContactsConfiguration can be found under Contacts. Properties marked with the report symbol are not accessible within the Configuration Object.

Example

Let's say you want to change the style of the Contacts subcomponent and, in addition, you only want to hide the submit button.

You can modify the style using the contactsStyle property and hide the submit button with the hideSubmitButton property.

app.component.ts
