# Overview

> **Info:** This is documentation for **Stream Chat React Native SDK v9**, which is no longer actively maintained. For up-to-date documentation, see the [latest version (v10)](https://getstream.io/chat/docs/sdk/react-native/).

This section covers the parts of the message UI that expose conversation follow-up and engagement: thread reply affordances and reaction rendering.

## Replies

- [`MessageReplies`](https://getstream.io/chat/docs/sdk/react-native/v9/ui-components/message-replies/) shows the reply count and thread entry point.
- [`MessageRepliesAvatars`](https://getstream.io/chat/docs/sdk/react-native/v9/ui-components/message-replies-avatars/) shows avatars for users who replied.

Use these components when you want to customize how thread activity is surfaced from the main message list.

## Reactions

The SDK provides separate components for reaction list placement and reaction chip rendering:

- [`ReactionListTop`](https://getstream.io/chat/docs/sdk/react-native/v9/ui-components/reaction-list-top/)
- [`ReactionListBottom`](https://getstream.io/chat/docs/sdk/react-native/v9/ui-components/reaction-list-bottom/)
- [`ReactionListClustered`](https://getstream.io/chat/docs/sdk/react-native/v9/ui-components/reaction-list-clustered/)
- [`ReactionListItem`](https://getstream.io/chat/docs/sdk/react-native/v9/ui-components/reaction-list-item/)
- [`ReactionListItemWrapper`](https://getstream.io/chat/docs/sdk/react-native/v9/ui-components/reaction-list-item-wrapper/)

## Recommendation

Start by choosing where reactions should appear on the message. After that, customize the list presentation or individual chips only if the default top or bottom placement is not enough.
