Developed TikTok embed support for Markdown content rendering in the nccasia/mezon-fe repository, focusing on scalable front-end architecture. The work involved refactoring the existing YouTube embed into a reusable SocialEmbed component, enabling multi-platform social content embedding. By consolidating embed logic under a unified layer, the approach improved maintainability and set a foundation for future extensibility. The implementation included URL detection and rendering utilities for TikTok links, enhancing the authoring and content engagement experience. Leveraging React and TypeScript, the developer delivered the feature in a single, disciplined commit, demonstrating a methodical approach to incremental delivery and codebase modernization.
