Component Library Architecture

A component library is the implementation layer of your design system — it's the actual code and Figma components that teams use daily. A well-architected library follows key principles: single responsibility (each component does one thing well), composition over configuration (combine simple components instead of building mega-components), controlled vs uncontrolled patterns, accessibility by default (not as an afterthought), and comprehensive documentation. In Figma, use auto-layout, component properties (boolean, instance swap, text), and variants to create flexible components. For code, ensure every component accepts standard HTML attributes, supports refs, and manages its own state minimally.

Essential Component Categories

  • Layout: Container, Grid, Stack, Flex, Divider, Spacer — the structural foundation for page composition
  • Navigation: Navbar, Sidebar, Breadcrumbs, Tabs, Pagination, Link, Menu — how users move through the product
  • Data Input: Button, Input, Select, Checkbox, Radio, Toggle, Slider, DatePicker, FileUpload, SearchBar — how users interact
  • Data Display: Card, Table, List, Badge, Avatar, Tag, Tooltip, Accordion, Timeline — how information is presented
  • Feedback: Alert, Toast/Snackbar, Progress, Spinner, Skeleton, Modal, Dialog, ConfirmationDialog — system communication
  • Typography: Heading, Text, Code, Blockquote, Label — text rendering with semantic meaning
  • Media: Image, Video, Carousel, Lightbox, Icon — visual content display

Component Documentation Standards

  • Description: What the component is and when to use it — include 'when to use' and 'when NOT to use' guidance
  • Props/Properties: Every prop documented with type, default value, description, and whether it's required
  • Variants: All visual variants with examples — primary, secondary, outlined, ghost, destructive for buttons
  • States: Interactive states documented — default, hover, active, focus, disabled, loading, error
  • Sizes: Available sizes with pixel dimensions — sm, md, lg — and when to use each
  • Accessibility: ARIA roles, keyboard interactions, screen reader behavior, color contrast ratios
  • Do's and Don'ts: Visual examples of correct and incorrect usage — these prevent the most common misuse
  • Code Examples: Copy-pasteable code for the most common use cases — lower the barrier to adoption
