Pull Request: Upgrade react-markdown in stream-chat-react

🎯 Goal

The goal of this change is to upgrade the react-markdown dependency from version v8.0.7 to v9.0.3 in the stream-chat-react package to resolve compatibility issues with modern React versions.

Problem Description

The stream-chat-react package currently uses an outdated version of the react-markdown library (v8.0.7). This version causes compatibility issues with modern React projects, including React 19 and Next.js, resulting in:

• Build Errors: Issues such as Cannot find namespace "JSX" during builds.
• Dependency Conflicts: Mismatches with updated React libraries.

Solution

To resolve these issues, this PR updates all instances of react-markdown in stream-chat-react to use version v9.0.3. The update also ensures that:

1. Functionality Remains Intact: Verified that all features using react-markdown continue to work as expected.
2. Dependencies Are Aligned: Ensured compatibility with peer libraries and React versions.

Changes Summary

• Replaced react-markdown@8.0.7 with react-markdown@9.0.3.
• Updated usage of react-markdown throughout the stream-chat-react codebase.

Submission Details

• Testing: All usage of react-markdown has been verified to function correctly.
• Documentation: No changes required, as there is no impact on public-facing APIs.

@prassamin this PR does not test the impacts it introduces. At the moment we do not plan to upgrade react-markdown. See this PR: #2461

Is there something that prevents you from upgrading on your side?

[prassamin]

@MartinCupela The issue I’m facing occurs specifically during the build process of my Next.js project. It throws errors related to JSX and TypeScript compatibility

[prassamin]

And when I use the npm overrides feature to upgrade react-markdown to version 9.0.3:

"overrides": {
  "react-markdown": "9.0.3"
}

it results in errors during the development phase.
