Code Examples

Code Examples Overview

At its core, code examples is about doing one thing well inside your design systems project. Once you understand the pattern, you can apply it consistently across features and teams.

Good code examples pays off across the whole codebase: fewer surprises, easier testing, and smoother onboarding. The snippet below is a solid starting point.

/* A design system pairs shared tokens with reusable components */
:root {
  --color-brand-500: #2563eb;
  --space-4: 16px;
  --radius-md: 8px;
}

.button-primary {
  background: var(--color-brand-500);
  padding: var(--space-4);
  border-radius: var(--radius-md);
}

A design system connects tokens, components, and documentation into one shared language.

Code Examples Example

/* Tokens flow into components, which flow into products */
:root { --color-brand-500: #2563eb; }
.button { background: var(--color-brand-500); }

• Start from a minimal Code Examples example and grow it only as needed.
• Keep configuration explicit so Code Examples behaves the same in every environment.
• Name things clearly so teammates understand your Code Examples at a glance.
• Add tests around Code Examples early to lock in expected behaviour.

How Code Examples Fits into a Design System

Code Examples connects the design decisions in your system to the code teams actually ship. When it is defined once and reused, products stay consistent and updates roll out everywhere.

A design system connects tokens, components, and documentation into one shared language.

• Define it once as a token or shared component.
• Document intended usage with clear examples.
• Make it themeable and accessible by default.
• Version and release changes so consumers can upgrade safely.

Getting Teams to Adopt Code Examples

Adoption is where design systems succeed or stall. Make code examples the easiest option: great docs, sensible defaults, and clear migration paths beat mandates every time.

Common Mistakes

• Copying code examples snippets without understanding what each line does.
• Skipping error handling and edge cases when wiring up code examples.
• Leaving code examples untested, so regressions slip into production.
• Over-engineering code examples before you actually need the extra flexibility.

Key Takeaways

• Code Examples is a core part of working effectively with design systems.
• Start small and keep code examples focused on a single responsibility.
• Apply consistent patterns so code examples scales across your project.
• Test and document code examples to keep it maintainable over time.
