Jakob Sanne-Grubbstrom developed and maintained the migrationsverket/midas UI component library over five months, focusing on production readiness, accessibility, and streamlined release processes. He refactored core components such as Button, Modal, and Date Picker, modernizing APIs and adopting updated design tokens to ensure visual consistency and accessibility. Using TypeScript, React, and CSS Modules, Jakob improved build tooling, automated versioning, and enhanced documentation with Docusaurus and Storybook. His work included removing deprecated props, consolidating changelogs, and implementing CI/CD workflows, resulting in a more maintainable codebase, faster onboarding for contributors, and a reliable, scalable foundation for future feature development.

May 2025 monthly summary for migrationsverket/midas: Delivered a broad API cleanup and documentation uplift across the UI library in preparation for the 10.0.0 release. Key API cleanups included removing deprecated props and modernizing usage across Button, Accordion, Modal, Spinner, Tabs, and Table; these changes reduce surface area, simplify migrations, and improve consistency across products. Implemented token rebranding and introduced new color tokens, plus updated link colors to align with the updated design system. Updated several components to use medium button size to improve visual consistency and accessibility. Added comprehensive changelog and release notes in a Docusaurus-style format, including migrations for 10.0.0 across Button, Accordion, Modals, Spinner, and Tabs, as well as migration notes for Label and Skeleton. Improved documentation quality (fixing code docs, rendering JSDoc as Markdown) and added 10.1.0 release notes. Reworked release artifacts to support smoother upgrades and future deprecations.

March 2025 (migrationsverket/midas) delivered a focused set of design-system improvements, accessibility enhancements, and release-process optimizations that drive a more consistent user experience and faster delivery cycles. Key features delivered include a Date Picker refactor with rangecalendar extracted to its own component, added stories, and token updates; a broad Token-based UI refresh for Date Field, Calendar, and Text Area to adopt updated design tokens; and a major Modal system overhaul with boilerplate, focus trap groundwork, and overlay/z-index improvements, plus API/docs/tests alignment and deprecation of older ModalTrigger/Dialog components. Additional work stabilized UI and docs: Button high-contrast mode enhancement; extensive documentation updates (bug reporting, localization dev instructions, Prism language docs, styleguide); and release automation improvements (version bumps across major releases, publish.yml tweaks, and husky script updates). Stability efforts included reverting playground app changes to stabilize the baseline and updating tests/stories for the new modal API. Overall impact: more consistent theming, improved accessibility and UX, safer and faster releases, and clearer developer onboarding through stronger docs and tooling.
