Worked on the element-plus/element-plus repository to enhance the reliability of the Upload component by addressing a nuanced file deletion issue. Focused on improving the removeFile logic, the solution shifted from direct object comparison to UID-based filtering, ensuring files are correctly deleted whether or not v-model is used. This approach eliminated inconsistencies and orphaned files, resulting in a more stable user experience and easier maintenance. The work leveraged Vue.js for component development and TypeScript for type safety, demonstrating attention to edge cases and robust front-end engineering practices. The contribution centered on bug resolution rather than feature development during the period.
