Message Composer - CometChat Docs

Overview

MessageComposer is a Component that enables users to write and send a variety of messages, including text, image, video, and custom messages. Features such as Live Reaction, Attachments, and Message Editing are also supported by it.

MessageComposer is comprised of the following Base Components:

Base Components	Description
MessageInput	This provides a basic layout for the contents of this component, such as the TextField and buttons
ActionSheet	The ActionSheet component presents a list of options in either a list or grid mode, depending on the user’s preference

Usage

Integration

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

import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { CometChatMessageComposer } from '@cometchat/chat-uikit-angular';
import { AppComponent } from './app.component';

@NgModule({
  imports: [
    BrowserModule,
    CometChatMessageComposer
  ],
  declarations: [AppComponent],
  providers: [],
  bootstrap: [AppComponent],
  schemas: [CUSTOM_ELEMENTS_SCHEMA]
})
export class AppModule { }

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. OnSendButtonClick

The OnSendButtonClick event gets activated when the send message button is clicked. It has a predefined function of sending messages entered in the composer EditText. However, you can overide this action with the following code snippet.

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" })
  }

  public handleOnSendButtonClick = (message: CometChat.BaseMessage) =>{
    console.log("Your Custom send button click actions", message);
  };

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

2. onError

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

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" })
  }

  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 });
      }
    );
  }
}

Filters

MessageComposer component does not have any available 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 list of events emitted by the Messages component is as follows.

Event	Description
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
ccMessageSent	Triggers whenever a loggedIn user sends any message, it will have three states such as: inProgress, success and error
ccLiveReaction	Triggers whenever a loggedIn clicks on live reaction

Adding CometChatMessageEvents Listener’s

import {CometChatMessageEvents} from "@cometchat/chat-uikit-angular";

this.ccMessageEdited = CometChatMessageEvents.ccMessageEdited.subscribe(
 () => {
        // Your Code
  }   
);

this.ccMessageSent = CometChatMessageEvents.ccMessageSent.subscribe(
  () => {
        // Your Code
  }        
);

this.ccLiveReaction = CometChatMessageEvents.ccLiveReaction.subscribe(
  () => {
        // Your Code
  }      
);

Removing CometChatMessageEvents Listener’s

this.ccMessageEdited.unsubscribe();
this.ccMessageSent.unsubscribe();

Customization

To fit your app’s design requirements, you can customize the appearance of the MessageComposer 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. MessageComposer Style

To modify the styling, you can apply the MessageComposerStyle to the MessageComposer Component using the messageComposerStyle property.

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

  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" })
  }

  messageComposerStyle = new MessageComposerStyle({
    AIIconTint:"#ec03fc",
    attachIcontint:"#ec03fc",
    background:"#fffcff",
    border:"2px solid #b30fff",
    borderRadius:"20px",
    inputBackground:"#e2d5e8",
    textColor:"#ff299b",
    sendIconTint:"#ff0088",  
  });
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

2. MediaRecorder Style

To customize the styles of the MediaRecorder component within the MessageComposer Component, use the mediaRecorderStyle property. For more details, please refer to MediaRecorder styles.

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

  mediaRecorderStyle = new MediaRecorderStyle({
    background:"#f2f5fa",
    border:"2px solid #be0be6",
    closeIconTint:"#830be6",
    submitIconTint:"#c2a3ff",
    startIconTint:"#a313f0"
  });
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

3. MentionsWarning Style

To customize the styles of the MentionsWarning within the MessageComposer Component, use the mentionsWarningStyle property.

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" })
  }

  mentionsWarningStyle: any = ({
    backgroundColor:'red',
    height:'50px',
    width:'200px'
  });
  onLogin(UID?: any) {
    CometChatUIKit.login({ uid: UID }).then(
      (user) => {
        setTimeout(() => {
          window.location.reload();
        }, 1000);
      },
      (error) => {
        console.log("Login failed with exception:", { error });
      }
    );
  }
}

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.

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

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

AttachmentOptions

By using attachmentOptions, you can set a list of custom MessageComposerActions for the MessageComposer Component. This will override the existing list of MessageComposerActions. Example

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

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" })
  }
  getAttachmentOptions = (item: CometChat.User | CometChat.Group, composerId: ComposerId)=>{
    const CustomAttachment = [
      new CometChatMessageComposerAction({
          id: 'your custom id',
          iconURL: 'icon',
          background: 'blue',
          title: 'Your Custom Title',
          iconTint: '#9000ff'
      })
    ];
    if(item instanceof CometChat.User) {
      //push user specific custom attachment options
    } else if(item instanceof CometChat.Group) {
      //push group specific custom attachment options
    }
    return CustomAttachment;
  };

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

AuxiliaryButtonView

You can insert a custom view into the MessageComposer component to add additional functionality using the following method. Please note that the MessageComposer Component utilizes the AuxiliaryButton to provide sticker functionality. Overriding the AuxiliaryButton will subsequently replace the sticker functionality. In this example, we’ll be adding a custom SOS button. Example

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

  name = 'Your Custom name';
  auxiliaryButtonURL = 'Your custom url';
  getIconStyle = new IconStyle({
    iconTint:"#d400ff",
  });

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

SecondaryButtonView

You can add a custom view into the SecondaryButton component for additional functionality using the below method. In this example, we’ll be adding a custom SOS button. Example

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

  name = 'Your Custom name';
  secondaryButtonURL = 'Your custom url';
  getIconStyle = new IconStyle({
    iconTint:"#d400ff",
  });

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

SendButtonView

You can set a custom view in place of the already existing send button view. Using the following method. Example

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

  name = 'Your Custom name';
  customURL = 'Your custom url';
  getIconStyle = new IconStyle({
    iconTint:"#d400ff",
  });

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

HeaderView

You can set custom headerView to the MessageComposer component using the following method In the following example, we’re going to apply a mock chat bot button to the MessageComposer Component using the headerView property. Example

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" })
  }
  myCustomIcon = 'Your custom url';


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

TextFormatters

Assigns the list of text formatters. If the provided list is not null, it sets the list. Otherwise, it assigns the default text formatters retrieved from the data source. To configure the existing Mentions look and feel check out CometChatMentionsFormatter. Example

import { CometChatTextFormatter } from "@cometchat/uikit-shared";
import { Subject } from 'rxjs';
import { CometChat } from "@cometchat/chat-sdk-javascript";

export class ShortcutFormatter extends CometChatTextFormatter {
    private shortcuts: { [key: string]: string } = {};
    private dialogIsOpen: boolean = false;
    private currentShortcut: string | null = null;
    private openDialogSubject = new Subject<{ closeDialog?: boolean, buttonText?: string, shortcut?: string, handleButtonClick?:any }>();
    openDialog$ = this.openDialogSubject.asObservable();

    constructor() {
        super();
        this.setTrackingCharacter('!');
        CometChat.callExtension('message-shortcuts', 'GET', 'v1/fetch', undefined)
            .then((data: any) => {
                if (data && data.shortcuts) {
                    this.shortcuts = data.shortcuts;
                }
            })
            .catch(error => console.log("error fetching shortcuts", error));
    }

Configuration

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

UserMemberWrapper

From the MessageComposer, you can navigate to the UserMemberWrapper component as shown in the image.

If you wish to modify the properties of the UserMemberWrapper Component, you can use the UserMemberWrapperConfiguration object.

import { CometChat } from '@cometchat/chat-sdk-javascript';
import { Component, OnInit } from '@angular/core';
import { CometChatThemeService, CometChatUIKit } from '@cometchat/chat-uikit-angular';
import { UserMemberWrapperConfiguration } from '@cometchat/uikit-shared';
import { UserPresencePlacement } from '@cometchat/uikit-resources';
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 userMemberWrapperConfiguration= new UserMemberWrapperConfiguration({
    userPresencePlacement: UserPresencePlacement.right,
    //properties of UserMemberWrapper
  });


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

The UserMemberWrapperConfiguration indeed provides access to all the Action, Filters, Styles, Functionality, and Advanced properties of the UserMemberWrapper component. Please note that the Properties marked with the 🛑 symbol are not accessible within the Configuration Object. Example

In the above example, we are styling a few properties of the UserMemberWrapper component using UserMemberWrapperConfiguration.
