Qijia Liu focused on front-end development for the EnergySage/es-ds repository, addressing a targeted issue in the es-video component. Using Vue.js, Qijia enhanced the YouTube video ID extraction logic by updating the regular expression to support IDs containing underscores, a detail previously unhandled. This technical adjustment ensured that videos with such IDs embedded correctly, directly improving content reliability and reducing broken media instances across the platform. The work involved validating the new regex end-to-end, confirming that video embeds functioned as intended. Qijia’s contribution, though limited in scope, demonstrated careful attention to detail and a solid grasp of JavaScript and Vue.
