Component Libraries and Design System Workflow
A design system is a shared toolbox of styles and components so many teams can build faster without making every screen look different.
Instead of each class bringing random chairs, the school uses one standard furniture system so every room stays familiar and easier to maintain.
Topic practice prompts
Start with tokens and primitives, then build higher-level components with consistent APIs, documentation, accessibility rules, and versioning.
- What belongs in a primitive versus a product component?
- How do you avoid over-engineering shared components?
Allow composition and clear extension points, but keep tokens, accessibility rules, and core APIs strict enough to protect consistency.
- How do you decide when to add a new variant?
- Who should approve shared-component changes?
Last-day revision lines
- Tokens first, components second.
- Document usage and edge cases.
- Consistency beats one-off cleverness.
- Measure adoption and maintenance cost.
