Worked on the rspack-contrib/rstack-examples repository to enhance development workflow stability and performance by addressing a hot module replacement (HMR) inefficiency. Focused on build tools and frontend configuration using TypeScript, the developer implemented a targeted fix that excluded node_modules from react-refresh processing. This adjustment resolved an edge case where unnecessary files were processed, leading to conflicts and slower hot-reload cycles. By refining the exclude pattern in the HMR configuration, the change minimized rebuild times and reduced hot-reload conflicts. The work delivered a precise, single-source update that improved build performance and streamlined frontend development without introducing new features.
