Worked on modernizing dependency management for the kartverket/kvib repository by upgrading its React peer dependency to version 18 and above. This update aligned the project with the latest React ecosystem, enabling the use of new features and improving compatibility for downstream consumers. The process involved careful validation of builds and tests to ensure no regressions were introduced, with all changes thoroughly documented in a Markdown changeset. Focused on frontend development and dependency management, the work enhanced maintainability and prepared the codebase for future enhancements, while maintaining stability and clear communication with users relying on the updated React integration.
