Message Template

Overview​

A MessageTemplate provides you with the capability to define and customize both the structure and the behavior of the MessageBubble. It acts as a schema or design blueprint for the creation of a variety of MessageBubble components, allowing you to manage the appearance and interactions of MessageBubble within your application effectively and consistently.

Structure​

Image

The MessageBubble structure can typically be broken down into the following views:

  1. Leading view: This is where the sender's avatar is displayed. It's typically on the left of the MessageBubble for messages from others and on the right for messages from the current user.

  2. Header view: This displays the sender's name and is especially useful in group chats where multiple users are sending messages.

  3. Reply view: This view can be used to extend the MessageBubble with additional elements. It's typically placed above the Content view.

  4. Content view: This is the core of the MessageBubble where the message content (text, images, videos, etc.) is displayed.

  5. Bottom view: This view can be used to extend the MessageBubble with additional elements, such as link previews or a 'load more' button for long messages. It's typically placed beneath the Content view.

  6. Thread view: This is where the thread reply icon and reply counts are displayed. It's located below the footer view.

  7. Footer view: This is where the reactions are displayed. It's located at the bottom of the MessageBubble.

  8. status Info view: This is where the timestamp of the message and its delivery or read status are displayed. It's located inside the MessageBubble just below the content view.

Properties​

MessageTemplate provides you with methods that allow you to alter various properties of the MessageBubble. These properties include aspects such as the type and category of a message, the appearance and behavior of the header, content, and footer sections of the message bubble,

  1. type

    Using type you can set the type of CometChatMessage, This will map your MessageTemplate to the corresponding CometChatMessage. You can set the MessageTemplates Type using the following code snippet.

  2. category

    Using category you can set the category of a MessageTemplate. This will create a MessageTemplate with the specified category and link it with a CometChatMessage of the same category.

    Please refer to our guide on Message Categories for a deeper understanding of message categories.

  3. headerView

    The headerView method allows you to assign a custom header view to the MessageBubble. By default, it is configured to display the sender's name.

  4. contentView

    The contentView method allows you to assign a custom content view to the MessageBubble. By default, it displays the Text Bubble, Image Bubble, File Bubble, Audio Bubble, or Video Bubble, depending on the message type.

  5. footerView

    The footerView method allows you to assign a custom Footer view to the MessageBubble. By default it shows thr reactions for the message bubble.

  6. bottomView

    The bottomView method allows you to assign a custom Bottom view to the MessageBubble. By defuault is has buttons such as link previews or a 'load more' button for long messages.

  7. bubbleView

    The bubbleView method allows you to assign a custom Bubble view to the MessageBubble. By default, headerView, contentView, statusInfoView and footerView together form a message bubble.

  8. statusInfoView

    The statusInfoView method allows you to assign a custom status info view to the MessageBubble. By default, it displays the receipt and timestamp.

  9. options

    The options lets you set the list of actions that a user can perform on a message. This includes actions like reacting to, editing, or deleting a message.

   let definedTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates();
   const CUSTOM_MESSAGE_TYPE = "your custom messagetype"
   let customMessageTemplate = new CometChatMessageTemplate({
       type: CUSTOM_MESSAGE_TYPE,
       category: CometChatUIKitConstants.MessageCategory.custom,
       headerView: //your custom header view
       contentView: //your custom content view
       footerView: //your custom footer view
       bottomView: // your custom bottom view
       bubbleView: // your custom bubble view
       options: //your custom options
   });
   definedTemplates.push(customMessageTemplate);

Customization​

Let's dive into how you can use the properties of MessageTemplate to customize an existing template or add a new one to the MessageList component.

The First step is to fetch the list of existing templates when you want to modify or add to them. This can be done using the getAllMessageTemplates() method from the DataSource of the CometChatUIKit class.

let definedTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates();

Existing Templates​

You will need to first get the MessageTemplate object for the type of message you want to customize. You will be customizing the TextMessage Bubble here. The code snippet to get the Text MessageTemplate is as follows.

import {
  CometChatUIKit,
  CometChatUIKitConstants,
} from "@cometchat/chat-uikit-react";

let allTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates();
for (let i = 0; i < allTemplates.length; i++) {
  if (allTemplates[i].type === CometChatUIKitConstants.MessageTypes.text) {
    //customize allTemplates[i]
  }
}

You will be using Messages Component for example here so to apply Template to Messages you will need to use MessageListConfiguration. This is because the templates function, which is used to apply the custom templates, belongs to the MessageList component.

You can apply MessageTemplatess to Messages Component using the following code snippet.

const messageListConfiguration = new MessageListConfiguration({
    templates: templates,
});

<CometChatMessages
  user={chatUser} 
  messageListConfiguration={messageListConfiguration} 
/>

HeaderView​

The headerView method of MessageTemplate allows you to add custom views to the header of your message bubbles. In the example below, we will add a custom header view of every text message in the MessageList.

CustomMessageTemplate.tsx
import React from "react";
import { CometChatMessages, CometChatUIKit , CometChatUIKitConstants, CometChatMessageTemplate, MessageListConfiguration } from '@cometchat/chat-uikit-react';
import { CometChat } from "@cometchat/chat-sdk-javascript";

const CustomMessageTemplate = () => {
    const [templates, setTemplates] = React.useState<CometChatMessageTemplate[]>([]);
    const [chatUser, setChatUser] = React.useState<CometChat.User>();
    React.useEffect(() => {
        CometChat.getUser("uid").then((user) => {
            setChatUser(user);
        })

       let definedTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates();
       const template =  definedTemplates.map((templates)=>{
            if (templates.type === "text" && templates.category === CometChatUIKitConstants.MessageCategory.message) {
                templates.headerView = (message:CometChat.BaseMessage) => getHeaderView(message)
                return templates;
            }
            return templates
        })
        setTemplates(template);
    }, []);

      const getHeaderView = (message: CometChat.BaseMessage) => {
        return(
            <cometchat-avatar image="custom avatar"/>
        )
      }
      const messageListConfiguration = new MessageListConfiguration({
        templates: templates,
      });

    return (
        <div style={{height:"100%", width:"100%"}}>
        <CometChatMessages

            messageListConfiguration={messageListConfiguration}
        />
        </div>
    )
}

export { CustomMessageTemplate };

Contentview​

The contentview method of MessageTemplate allows you to add a custom view to the content of your message bubbles. In the example below, we will add a custom layout to the content view of every text message in the MessageList.

    const [chatUser, setChatUser] = React.useState<CometChat.User>();
    React.useEffect(() => {
        CometChat.getUser("uid").then((user) => {
            setChatUser(user);
        })

        let definedTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates();
        const CUSTOM_MESSAGE_TYPE = "nudge";
        let customMessageTemplate = new CometChatMessageTemplate({
            type: CUSTOM_MESSAGE_TYPE,
            category: CometChatUIKitConstants.MessageCategory.custom,
            contentView: (message: CometChat.BaseMessage) => getContentView(message),
        });
        definedTemplates.push(customMessageTemplate);
        setTemplates(definedTemplates);
    }, []);

    const getContentView = (message: CometChat.BaseMessage) => {
        return (

                <img src={rocketIcon} alt="gif" />
            </div>
        )
    }
    const getMessageRequestBuilder = () => {
        let categories = CometChatUIKit.getDataSource().getAllMessageCategories();
        categories.push(CometChatUIKitConstants.MessageCategory.custom);
        let types = CometChatUIKit.getDataSource().getAllMessageTypes();
        types.push(CUSTOM_MESSAGE_TYPE);
        return new CometChat.MessagesRequestBuilder().setCategories(categories).setTypes(types).hideReplies(true).setLimit(30);
    }
    const messageListConfiguration = new MessageListConfiguration({
        templates: templates,

        />
        </div>
    )
}

export { CustomMessageTemplate };

StatusInfoView​

The statusInfoView method of MessageTemplate allows you to add a status info view to your message bubbles. In the example below, we will add a custom status info view to every text message in the MessageList.

Image
CustomMessageTemplate.tsx
import React from "react";
import { CometChatMessages, CometChatUIKit, CometChatUIKitConstants, CometChatMessageTemplate, MessageListConfiguration, TextBubbleStyle } from '@cometchat/chat-uikit-react';

    const [chatUser, setChatUser] = React.useState<CometChat.User>();

    React.useEffect(() => {
        CometChat.getUser("uid").then((user) => {
            setChatUser(user);
        })

        let definedTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates();
        const template = definedTemplates.map((templates) => {
            if (templates.type === "text" && templates.category === CometChatUIKitConstants.MessageCategory.message) {
                templates.statusInfoView = (message: CometChat.BaseMessage) => getStatusInfo(message)
                return templates;
            }
            return templates
        })
        setTemplates(template);
    }, []);

    const getStatusInfo = (message: CometChat.BaseMessage) => {
        if (message instanceof CometChat.TextMessage) {
            const timestamp = message.getDeliveredAt();
            const date = new Date(timestamp * 1000);
            const hours = date.getHours();
            const minutes = date.getMinutes();
            const period = hours >= 12 ? 'PM' : 'AM';
            const formattedHours = hours % 12 || 12;
            const formattedMinutes = minutes < 10 ? '0' + minutes : minutes;
            const formattedTime = `${formattedHours}:${formattedMinutes} ${period}`;

            />
        </div>
    )
}

export { CustomMessageTemplate };

Options​

The options method in the MessageTemplate allows you to customize the options that appear in the action sheet when a message is long-pressed. By default, CometChat UI Kit provides a set of options like "Thread Reply", "Copy" ,"Edit", and "Delete".

However, if you wish to override or modify these options, you can use the options method and pass a list of CometChatMessageOption. This list of options will replace the default set.

New Templates​

You can create an entirely new template for custom messages is one of the powerful features of CometChat's MessageTemplate.

Image
CustomMessageTemplate.tsx
import React from "react";
import { CometChatMessages, CometChatUIKit,IconStyle , CometChatUIKitConstants, CometChatMessageTemplate, MessageListConfiguration, MessageComposerConfiguration, CometChatUIKitUtility} from '@cometchat/chat-uikit-react';

import rocketIcon from "./rocket.gif";
import nudgeIcon from "./nudgeIcon.svg";


const CustomMessageTemplate = () => {
    const [templates, setTemplates] = React.useState<CometChatMessageTemplate[]>([]);
    const [chatUser, setChatUser] = React.useState<CometChat.User>()
    React.useEffect(() => {
        CometChat.getUser("uid").then((user) => {
            setChatUser(user);
        })
    }, [])

    const CUSTOM_MESSAGE_TYPE = "nudge";

    React.useEffect(() => {
        let definedTemplates = CometChatUIKit.getDataSource().getAllMessageTemplates();
        let customMessageTemplate = new CometChatMessageTemplate({
            type: CUSTOM_MESSAGE_TYPE,
            category: CometChatUIKitConstants.MessageCategory.custom,
