In this video, we dive into the technical challenge we faced when upgrading to Anthropic Claude 3.7 Sonnet: our Diff Viewer started freezing browsers when loading many files at once. The root cause? Each CodeMirror instance blocks the browser during initialization, and loading too many simultaneously caused major performance issues.

Watch as we explain how we used React time slicing to break up the workload into smaller batches, allowing the browser to stay responsive even when displaying 20+ files. This approach drastically improves the user experience by avoiding long blocking tasks and making UI interactions smooth.

If you’re building complex web apps or working with multiple code editors, this deep dive into performance optimization with React, CodeMirror, and browser rendering insights will be invaluable.
