Improve Code Generation with Figma's Code Connect UI

What Is Code Connect?

Figma's Code Connect is a feature that links Figma components to their actual code implementations. When a developer inspects a Figma component, instead of seeing generic CSS snippets, they see the real React/Vue/SwiftUI code that implements that component.

For AI coding tools, this is transformative. When an AI agent can see that a Figma 'Button' component maps to your <Button variant='primary' size='md'> React component, it generates code that uses your actual component library — not a generic approximation.

Code Connect works by maintaining a mapping file in your codebase that tells Figma which code corresponds to which design component. This mapping flows through to AI tools that read Figma data, creating a closed loop between design and implementation.

Setting Up Code Connect

Getting Code Connect running requires setup in both Figma and your codebase.

npm install --save-dev @figma/code-connect

import figma from '@figma/code-connect'
import { Button } from './components/ui/button'

figma.connect(Button, 'https://figma.com/file/.../Button', {
  props: {
    label: figma.string('Label'),
    variant: figma.enum('Variant', {
      Primary: 'primary',
      Secondary: 'secondary',
      Ghost: 'ghost',
    }),
    size: figma.enum('Size', {
      Small: 'sm',
      Medium: 'md',
      Large: 'lg',
    }),
  },
  example: (props) => <Button variant={props.variant} size={props.size}>{props.label}</Button>,
})

Linking Components to Code

The real power of Code Connect emerges when you map your entire design system:

Property Mapping: Figma component properties (variant toggles, size selectors, boolean switches) map directly to React props. When Figma shows 'Variant: Primary, Size: Large,' the code shows <Button variant='primary' size='lg'>.

Nested Components: When a Card contains a Button and an Avatar, Code Connect shows the composed implementation — how the components nest in code, not just how they look in design.

State Variants: Map Figma's interaction states (default, hover, active, disabled, loading) to your component's state management. AI tools can then generate components with proper state handling.

Responsive Variants: If your component has mobile/desktop variants in Figma, map them to responsive breakpoints in code. The AI understands that the mobile design maps to md:hidden and the desktop design to hidden md:block.
