Austin enhanced the Assessment Editor in the PrairieLearn/PrairieLearn repository, focusing on user experience, accessibility, and code maintainability. He implemented features that persist editor UI state via URL query parameters, allowing instructors to retain context across page refreshes and reducing the risk of data loss. Austin improved accessibility by refining ARIA attributes, updating navigation semantics, and adjusting control visibility based on user selection. He simplified the codebase by removing obsolete feature flags and consolidating logic. Working primarily with React and TypeScript, Austin also strengthened automated test coverage, ensuring the editor’s stability and compliance with accessibility standards throughout the development process.

Mar 1, 2026March 2026 Monthly Summary — PrairieLearn/PrairieLearn Key focus: Enhancing the Assessment Editor for better UX, accessibility, and stability; simplifying the codebase; and strengthening test coverage. Key features delivered: - Assessment Editor Experience and Accessibility Enhancements: Improved UX and accessibility for the Assessment Editor, including opening question links in a new tab in edit mode to prevent work loss, removing redundant delete buttons, and making delete actions visible on selection. Also enhanced accessibility and formatting, with targeted className handling and updated ARIA/test IDs. - Persistence of assessment detail UI state: Added URL-query-based persistence for selected zones/questions/alternatives to retain user context across page refreshes, improving editing efficiency in long sessions. - Codebase simplification: Removed the assessment-questions-editor feature flag and related logic, reducing surface area and improving accessibility compliance. Major bugs fixed: - Reduced risk of losing work by preventing navigation away from the editor when opening related questions. - Accessibility compliance fixes and UI consistency improvements identified during testing (e.g., removing autoComplete off rules where blocking accessibility, updating nested-interactive rules handling). - Stabilized editing experience with preserved sidebar/selection state and updated test hooks to reflect new behavior. Overall impact and accomplishments: - Elevated business value by enabling instructors to edit assessments more efficiently with lower risk of data loss and higher accessibility compliance. - Improved maintainability and readability of the codebase through targeted refactors (clsx usage, clearer button visibility logic, and consolidated feature flags). - Strengthened QA and test coverage with updated test specs and ARIA/test-id attributes to support reliable automated checks. Technologies/skills demonstrated: - Frontend: React, TypeScript, dynamic class handling (clsx), useEffect/state management, URL query params, responsive panels (SplitPane). - Accessibility: ARIA labels, navigation semantics, and WCAG-aligned enhancements. - Testing: Updated test specs, accessibility tests, and test data alignment. - Collaboration: Co-authored changes across multiple contributors, as reflected in commit messages.
