Reusable Presentational Components
Design small, prop-driven UI pieces (buttons, cards, badges) that are easy to reuse; accept className/style overrides; avoid hidden side effects.
Reusable Presentational Components is a free React Academy lesson on CoddyKit — lesson 3 of 3. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the React Academy learning path, one of 3 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Why presentational components
Goal: Build prop-driven UI pieces that are easy to reuse and compose.
- Clear props API
- Stateless visuals
- Style overrides
Core guidelines
Principles:
- Read props, do not mutate them.
- No side effects; render-only.
- Expose className/style to customize.
Design a small API
Keep prop names obvious; provide safe defaults; prefer simple booleans like primary or disabled for variants.
Demo: presentational set
Example: small Button, Badge, and Card components that accept props and class overrides.
<div id="root"></div>
Composition tips
Tips:
- Accept children for flexible content.
- Expose className/style for tweaks.
- Keep variants minimal (e.g., primary).
Anti-patterns to avoid
Avoid:
- Mutating props inside components.
- Hidden global state changes.
- Hardcoding styles with no escape hatch.
Presentational best practice
Recap
Recap: Build small, prop-driven components with safe defaults, accept children and className, and avoid side effects for easy reuse.
