Group channel

A group channel is an invitation only channel that allows close interactions between a limited number of users and it's displayed using the GroupChannel module. In order to join a group channel, an invitation from the channel member is required by default. Users can create 1-to-1 group channels or 1-to-N group channels and there's also a supergroup channel, which is an expanded version of a group channel that can accommodate more than 2,000 members in one channel.

Usage

To start using the GroupChannel module, implement the following code:

import { GroupChannel } from '@sendbird/uikit-react/GroupChannel';

List of properties

The following table lists the properties of the GroupChannel module.

Context

To store and handle data that are used to build a group channel, Sendbird UIKit provides two context objects: GroupChannelProvider and useGroupChannelContext hook. GroupChannelProvider is a context provider that manages all the logic and data used in the group channel view. useGroupChannelContext is a context hook that allows access to the provider's data.

GroupChannelProvider

GroupChannelProvider contains input props and internal data that handle all the operations in the module. The provider stores data from Chat SDK in real-time and exports them to the UI components. The following code shows how to start using GroupChannelProvider.

import { GroupChannelProvider } from '@sendbird/uikit-react/GroupChannel/context';

List of properties

The following table lists the properties of GroupChannelProvider.

The following code shows how to start using useGroupChannelContext.

import { useGroupChannelContext } from '@sendbird/uikit-react/GroupChannel/context';

// Implement your code inside the react function component.
const Component = () => {
  const context = useGroupChannelContext();
  
  const onScrollDownButtonClick = () => {
    context.scrollToBottom();
  };
  
  // ...
}
