Worked on stabilizing build tooling for the web-infra-dev/rspack repository, focusing on improving the SwcJsMinimizerPlugin configuration. Addressed a bug by aligning the plugin’s TypeScript typings with the underlying SWC API, specifically renaming the unsafe_function option to unsafe_Function to ensure accurate mapping of minification settings. This adjustment reduced the risk of misconfiguration in production builds and enhanced the reliability of the minification process. The work involved close attention to build tools and minification workflows, prioritizing stability and developer experience over new feature development during the period. The contribution demonstrated depth in TypeScript and build system maintenance.
