Fanny Chienn updated the Next.js dependency to version 13.5.9 in the vtex/faststore repository, focusing on maintaining platform stability, security, and compatibility. She managed changes in the pnpm-lock.yaml file to ensure accurate package management and lockfile integrity. Her work involved validating storefront core flows against the new dependency to confirm there were no breaking changes, supporting a smooth upgrade path for future development. Using skills in dependency management and package management, along with expertise in YAML, Fanny’s contribution ensured the repository remained aligned with the evolving Next.js ecosystem and maintained a strong foundation for ongoing maintenance.
