Interview questions in Design Systems, page 7
Managing cross-framework parity in a design system
Shared token and spec source of truth, optional Web Components core, per-framework wrappers, a parity matrix, coordinated releases.
Automating design system standards enforcement
Custom ESLint and Stylelint rules for tokens and APIs, a11y testing with axe, editor and pre-commit hooks, blocking CI gates plus visual regression.
Automated detection of deprecated component usage
Machine-readable deprecation metadata, AST scanning across repos, scheduled jobs, per-team dashboards and PR-level warnings with codemod links.
Contribution model for a multi-framework system
Web Components core with thin React and Vue wrappers, shared tokens and spec, contribution rules requiring core-plus-wrapper changes, conformance tests.
Backporting a critical fix to an older major
Backport the fix to the supported older major as a patch, leveraging a documented support window and maintenance branches.
Automating a breaking design token rename
Ship a codemod to rewrite old token references, add a deprecation alias mapping old to new during a transition window, document the change.
Breaking token changes across multiple themes
A change is safe if every theme still satisfies the token's contract and contrast; dangerous if it breaks one theme, like a value that fails contrast in high-contrast mode.
Architecting density themes with tokens
Components reference semantic spacing tokens; a density theme repoints those tokens via CSS variables on a wrapper, so one stylesheet adapts.
A brand-only component consuming core tokens
Keep the unique component in a brand-specific package that depends on core tokens and primitives; do not add it to core.
Cross-platform Button API and implementation
Shared semantic props like variant, size, disabled, loading, onPress; web renders a button element with focus and CSS, native maps to platform touchables and accessibility traits.
