During August 2025, Yifei Wang developed an interactive API documentation demo for the requestAnimationFrame API within the lynx-family/lynx-website repository. The work focused on enhancing the developer experience by integrating a live, executable example that prints frame rates, available in both English and Chinese documentation. Yifei updated the dependency lockfile using YAML to ensure reproducible builds and maintain documentation quality. The project leveraged skills in API integration and technical documentation, utilizing Markdown for content structure. This contribution improved onboarding and visibility into API performance, aligning with the product roadmap and providing practical, hands-on guidance for developers using the Lynx API.
