Component Review Checklist

Component review checklists ensure consistent evaluation of design system components during code review and quality assurance processes. Checklists enumerate criteria that reviewers should verify, reducing oversight and ensuring thorough assessment regardless of individual reviewer experience or attention.

What Is a Component Review Checklist

A component review checklist is a structured list of criteria that reviewers verify when evaluating component changes. Checklists might cover visual accuracy, accessibility compliance, API design, code quality, documentation completeness, and test coverage. Systematic checklist use ensures comprehensive review.

Checklists address review consistency challenges. Without checklists, review thoroughness varies with reviewer expertise and attention. Important criteria may be overlooked. Checklists establish minimum review standards that all reviewers apply.

How Component Review Checklists Work

Criteria definition establishes what checklists include. Criteria should cover all aspects relevant to component quality. Categories might include visual review, accessibility, API review, implementation quality, testing, documentation, and cross-browser compatibility. Each category contains specific verifiable items.

Checklist format structures criteria for usability. Checkboxes enable marking items as verified. Grouping organizes related items. Conditional items apply only to certain change types. Notes fields capture observations. Format should support efficient review workflow.

Integration embeds checklists in review processes. Pull request templates can include checklists. Review tools can present checklists during evaluation. Automated checks can verify that checklist items were addressed. Integration ensures checklists are used rather than ignored.

Evolution updates checklists based on experience. New criteria are added when recurring issues suggest gaps. Obsolete criteria are removed when they become irrelevant or automated. Regular review keeps checklists valuable.

Documentation explains checklist rationale. Reviewers need to understand not just what to check but why each item matters. Documentation helps reviewers apply criteria appropriately and make judgment calls.

Key Considerations

• Checklists should be thorough but not so long they become burdensome
• Not every checklist item applies to every change; conditional applicability helps
• Checklists supplement but do not replace reviewer judgment
• Checklist compliance should be tracked to ensure actual use
• Checklists should be living documents that evolve with experience

Common Questions

What should a component review checklist include?

Comprehensive checklists address multiple areas. Visual review: Does the component match design specifications? Are all states implemented? Does it render correctly across viewports? Accessibility: Does it pass automated accessibility checks? Are ARIA attributes appropriate? Is keyboard navigation functional? API review: Do props follow naming conventions? Is the API consistent with similar components? Implementation: Is the code readable and maintainable? Are there performance concerns? Testing: Do tests cover key functionality? Are edge cases addressed? Documentation: Is usage documented? Are props described? Cross-browser: Does it work in supported browsers? Specific items depend on organizational priorities.

How should reviewers handle checklist items they cannot verify?

Some checklist items may require expertise or tools reviewers lack. Reviewers should explicitly note items they could not verify rather than checking them without verification. Such items might be deferred to specialist review or verified through alternative means. Tracking unverified items helps identify process gaps: if certain items are consistently unverifiable, either the checklist needs adjustment or reviewers need additional capabilities. Honest handling of unverifiable items maintains checklist integrity.

Summary

Component review checklists ensure consistent evaluation through defined criteria covering visual, accessibility, API, implementation, testing, and documentation aspects. Checklists integrate into review processes through templates and tooling. Effective checklists balance comprehensiveness with usability and evolve based on experience. Checklist items that reviewers cannot verify should be explicitly noted rather than assumed, maintaining checklist integrity and identifying process gaps.
