Where It Fits

CometChatMessageList renders a scrollable, real-time message feed for a user or group conversation. Wire it alongside CometChatMessageHeader and CometChatMessageComposer to build a standard chat view.

import { useState, useEffect } from "react";
import { View, StyleSheet } from "react-native";
import { GestureHandlerRootView } from "react-native-gesture-handler";
import { SafeAreaProvider } from "react-native-safe-area-context";
import {
  CometChatMessageHeader,
  CometChatMessageList,
  CometChatMessageComposer,
  CometChatThemeProvider,
} from "@cometchat/chat-uikit-react-native";
import { CometChat } from "@cometchat/chat-sdk-react-native";

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

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

  return chatUser ? (
    <GestureHandlerRootView style={{ flex: 1 }}>
      <SafeAreaProvider>
        <CometChatThemeProvider>
          <View style={styles.container}>
            <CometChatMessageHeader user={chatUser} />
            <CometChatMessageList user={chatUser} />
            <CometChatMessageComposer user={chatUser} />
          </View>
        </CometChatThemeProvider>
      </SafeAreaProvider>
    </GestureHandlerRootView>
  ) : null;
}

const styles = StyleSheet.create({
  container: { flex: 1 },
});

Minimal Render

import { CometChatMessageList } from "@cometchat/chat-uikit-react-native";

function MessageListDemo() {
  return <CometChatMessageList user={chatUser} />;
}

export default MessageListDemo;

Simply adding the CometChatMessageList component to the layout will result in an error. To fetch messages, you need to supplement it with user or group prop.

Filtering Messages

Pass a CometChat.MessagesRequestBuilder to messageRequestBuilder. The UID/GUID parameters are always overridden internally based on the user/group prop.

import { CometChatMessageList } from "@cometchat/chat-uikit-react-native";
import { CometChat } from "@cometchat/chat-sdk-react-native";

function FilteredMessageList() {
  return (
    <CometChatMessageList
      user={chatUser}
      messageRequestBuilder={
        new CometChat.MessagesRequestBuilder().setLimit(5)
      }
    />
  );
}

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

UID
GUID
types
categories

Refer to MessagesRequestBuilder for the full builder API.

Actions and Events

Callback Props

onThreadRepliesPress

Fires when you press on the threaded message bubble.

import { CometChatMessageList } from "@cometchat/chat-uikit-react-native";
import { CometChat } from "@cometchat/chat-sdk-react-native";

function MessageListWithThreads() {
  const handleThreadReplies = (
    msg: CometChat.BaseMessage,
    messageBubbleView: () => JSX.Element | null
  ) => {
    console.log("Thread replies pressed:", msg.getId());
  };

  return (
    <CometChatMessageList
      user={chatUser}
      onThreadRepliesPress={handleThreadReplies}
    />
  );
}

onError

Fires on internal errors (network failure, auth issue, SDK exception).

import { CometChatMessageList } from "@cometchat/chat-uikit-react-native";
import { CometChat } from "@cometchat/chat-sdk-react-native";

function MessageListWithErrorHandler() {
  return (
    <CometChatMessageList
      user={chatUser}
      onError={(error: CometChat.CometChatException) => {
        console.error("MessageList error:", error);
      }}
    />
  );
}

onReactionPress

Fires when a reaction on a message bubble is clicked.

import { CometChatMessageList } from "@cometchat/chat-uikit-react-native";
import { CometChat } from "@cometchat/chat-sdk-react-native";

function MessageListWithReactions() {
  const handleReactionPress = (
    reaction: CometChat.ReactionCount,
    messageObject: CometChat.BaseMessage
  ) => {
    console.log("Reaction pressed:", reaction, messageObject.getId());
  };

  return (
    <CometChatMessageList
      user={chatUser}
      onReactionPress={handleReactionPress}
    />
  );
}

onLoad

Fires when messages are successfully fetched and loaded.

import { CometChatMessageList } from "@cometchat/chat-uikit-react-native";
import { CometChat } from "@cometchat/chat-sdk-react-native";

function MessageListWithLoadHandler() {
  const handleLoad = (messageList: CometChat.BaseMessage[]) => {
    console.log("Messages loaded:", messageList.length);
  };

  return <CometChatMessageList user={chatUser} onLoad={handleLoad} />;
}

Global UI Events

CometChatUIEventHandler emits events subscribable from anywhere in the application. Subscribe in a useEffect and unsubscribe on cleanup.

Event	Fires when	Payload
`openChat`	User opens a user or group chat	`{ user, group }`
`ccMessageEdited`	Message edited by logged-in user	`{ message }`
`ccMessageDeleted`	Message deleted by logged-in user	`{ message }`
`ccActiveChatChanged`	User navigates to a different chat	`chat details`
`ccMessageRead`	Message read by logged-in user	`{ message }`
`ccMessageDelivered`	Messages marked as delivered	`{ message }`

import { useEffect } from "react";
import { CometChatUIEventHandler } from "@cometchat/chat-uikit-react-native";

function useMessageListEvents() {
  useEffect(() => {
    const uiListenerId = "UI_LISTENER_" + Date.now();
    const messageListenerId = "MESSAGE_LISTENER_" + Date.now();

    CometChatUIEventHandler.addUIListener(uiListenerId, {
      openChat: ({ user, group }) => {
        console.log("Chat opened:", user || group);
      },
    });

    CometChatUIEventHandler.addMessageListener(messageListenerId, {
      ccMessageEdited: ({ message }) => {
        console.log("Message edited:", message.getId());
      },
      ccMessageDeleted: ({ message }) => {
        console.log("Message deleted:", message.getId());
      },
    });

    return () => {
      CometChatUIEventHandler.removeUIListener(uiListenerId);
      CometChatUIEventHandler.removeMessageListener(messageListenerId);
    };
  }, []);
}

SDK Events (Real-Time, Automatic)

The component listens to these SDK events internally. No manual attachment needed unless additional side effects are required.

SDK Listener	Internal behavior
`onTextMessageReceived` / `onMediaMessageReceived` / `onCustomMessageReceived`	Appends new message to list
`onMessageEdited` / `onMessageDeleted`	Updates/removes message in list
`onTypingStarted` / `onTypingEnded`	Shows/hides typing indicator
`onMessagesDelivered` / `onMessagesRead`	Updates receipt ticks

Custom View Slots

Each slot replaces a section of the default UI.

Slot	Signature	Replaces
`HeaderView`	`({ user, group, id }) => JSX.Element`	Area above the message list
`FooterView`	`({ user, group, id }) => JSX.Element`	Area below the message list
`LoadingView`	`() => JSX.Element`	Loading state
`EmptyView`	`() => JSX.Element`	Empty state
`ErrorView`	`() => JSX.Element`	Error state
`NewMessageIndicatorView`	`() => JSX.Element`	New messages indicator
`templates`	`CometChatMessageTemplate[]`	Message bubble rendering
`textFormatters`	`CometChatTextFormatter[]`	Text formatting in messages

HeaderView

    const day = String(timeStampInSeconds.getUTCDate()).padStart(2, "0");
    const month = String(timeStampInSeconds.getUTCMonth() + 1).padStart(2, "0");
    const year = timeStampInSeconds.getUTCFullYear();
    return `${day}/${month}/${year}`;

    const timeStamp = message.getSentAt();
    if (timeStamp) {
      const date = new Date(timeStamp * 1000);
      const day = days[date.getUTCDay()];
      const hours = date.getUTCHours();
      const minutes = String(date.getUTCMinutes()).padStart(2, "0");
      return `${day}, ${hours}:${minutes}`;
    }
    return "---, --:--";
  };

  return (

      parentMessageId={parentMessage.getId()}
    />
  );
}

function MinimalMessageList() {
  return (
    <CometChatMessageList
      user={chatUser}
      receiptsVisibility={false}
      avatarVisibility={false}
      hideTimestamp={true}
      hideGroupActionMessages={true}
    />
  );
}

Left-aligned messages

import { CometChatMessageList } from "@cometchat/chat-uikit-react-native";

function LeftAlignedList() {
  return (
    <CometChatMessageList
      user={chatUser}
      alignment="leftAligned"
    />
  );
}

AI conversation starters

import { CometChatMessageList } from "@cometchat/chat-uikit-react-native";

function AIMessageList() {
  const suggestedMessages = [
    "How can I help you today?",
    "Tell me more about your issue.",
    "What would you like to achieve?",
  ];

  return (
    <CometChatMessageList
      user={chatUser}

  return (
    <CometChatMessageList
      user={chatUser}
