ComponentContext

The ComponentContext is a one of the context providers exposed by the Channel component and is consumable by all the children of Channel. This context provides UI component override options for maximum customization. All UI overrides that target children of the Channel component should be placed as Channel component props in order to be injected into the ComponentContext. The ComponentContext also exposes the hook useComponentContext.

Basic Usage

Pull values from context with our custom hook:

const { Attachment, Avatar, Message } = useComponentContext();

WithComponents

A component override functionality which utilises ComponentContext under the hood. This is direct replacement for a prop-based component overrides which are now slowly being deprecated.

Basic Usage of WithComponents

In this case, top-level MessageInput component reaches for the closest overrides and applies MessageInputUi1, the Thread component uses MessageInput internally and its UI can be also overriden - in this case, the closest one provides override with component MessageInputUi2. If we were to remove this WithComponents wrapper over Thread component, the closest override for Thread’s MessageInput component would be MessageInputUi1.

const MessageInputUi1 = () => {
  /*...*/
};
const MessageInputUi2 = () => {
  /*...*/
};

<Channel>
  <WithComponents overrides={{ Input: MessageInputUi1 }}>
    <Window>
      <MessageList />
      <MessageInput focus />
    </Window>
    <WithComponents overrides={{ Input: MessageInputUi2 }}>
      <Thread />
    </WithComponents>
  </WithComponents>
</Channel>;
