Worked on the didi/mpx repository to enhance build reliability and developer experience by addressing path handling and output path mapping. Tackled a bug in Unocss plugin development where files with dot-prefix paths were not recognized, implementing a fix that enabled correct plugin path matching. Introduced a resourcePath parameter to the customOutputPath configuration, allowing output paths to be derived directly from original resource locations. Updated documentation and tests to reflect these changes, ensuring maintainability and reducing regression risk. Utilized JavaScript, Webpack, and build tool configuration skills to deliver targeted improvements that align resource output with source locations and streamline workflows.
