Update a message

Update the content of a sent message. This replaces the original message content with the new content for all participants.

Update a message

Use the static BaseChannel.modifyMessage method, passing the Message object and the new content:

TypeScript

import { DirectChannel, BaseChannel, Message, TextMessageContent } from '@nexconn/chat';

const channel = new DirectChannel('<target-user-id>');

// First retrieve the message object you want to modify
const query = BaseChannel.createMessagesQuery({
  channelIdentifier: channel.identifier,
  startTime: Date.now(),
  pageSize: 20,
  isAscending: false,
});
const { code, data: page } = await query.loadNextPage();

if (code === 0 && page.data.length > 0) {
  const message = page.data[0] as Message<TextMessageContent>;
  const { code: modifyCode } = await BaseChannel.modifyMessage<TextMessageContent>({
    messageId: message.messageId,
    channelIdentifier: channel.identifier,
    content: { text: 'Updated message content' }, // Plain content object
  });
  if (modifyCode === 0) {
    console.log('Message updated');
  } else {
    console.log('Update failed. Code:', modifyCode);
  }
}

Parameters

Parameter	Type	Required	Description
messageId	string	Yes	The server-assigned message ID of the message to update
channelIdentifier	ChannelIdentifier	Yes	The identifier of the channel the message belongs to
content	T	Yes	The new message content as a plain object

Handle message update notifications

When a message is updated, all connected users receive the updated message through the message listener:

TypeScript

import { NCEngine, MessageHandler } from '@nexconn/chat';

NCEngine.addMessageHandler('modify-handler', new MessageHandler({
  onMessagesModified({ messages }) {
    messages.forEach((message) => {
      console.log('Message updated:', message.messageId, message.content);
    });
  },
}));

info

• Message updates are supported in direct channels, group channels, and community channels.
• The update is applied to the server-side message history.
• Content moderation (profanity filter, IM content moderation) is applied to the updated content as well.
