Worked on the sst/opentui repository to address stability and rendering reliability for Markdown tables during streaming transitions. Focused on front end development using TypeScript, the work involved rebuilding the Markdown table when transitioning between streaming and non-streaming modes to ensure the final table state remained accurate and to prevent stale renders. Implemented cache invalidation during these transitions to eliminate rendering artifacts and maintain consistent UI behavior. Expanded test coverage to validate the correctness of Markdown rendering across different streaming states, emphasizing thorough testing practices. The contributions centered on bug fixing and improving the robustness of the rendering logic within the application.
