Message

Delete a message

Copy link

Users can delete any message they themselves have sent. An error is returned if a user attempts to delete messages sent by others. Also channel operators can delete any messages in a channel. This works the same way for both open channels and group channels.

JavaScriptTypeScript
// The MESSAGE argument below indicates a UserMessage or FileMessage object to delete.
await channel.deleteMessage(MESSAGE);

After a message has been deleted, the onMessageDeleted() method in the channel event handler is invoked on all users' devices including the device where the message was deleted.

Open channel

Copy link
JavaScriptTypeScript
const channelHandler = new OpenChannelHandler({
        onMessageDeleted: (channel, message) => {
                // ...
        }
});

sb.openChannel.addOpenChannelHandler(UNIQUE_HANDLER_ID, channelHandler);

Group channel

Copy link
JavaScriptTypeScript
const channelHandler = new GroupChannelHandler({
        onMessageDeleted: (channel, messageId: number) => {
                // ...
        },
});

sb.groupChannel.addGroupChannelHandler(UNIQUE_HANDLER_ID, channelHandler);
