Code Connect Components

Overview

This skill helps you connect Figma design components to their corresponding code implementations using Figma's Code Connect feature. It analyzes the Figma design structure, searches your codebase for matching components, and establishes mappings that maintain design-code consistency.

Prerequisites

• Figma MCP server must be connected and accessible
• User must provide a Figma URL with node ID: https://figma.com/design/:fileKey/:fileName?node-id=1-2
  • IMPORTANT: The Figma URL must include the node-id parameter. Code Connect mapping will fail without it.
• OR when using figma-desktop MCP: User can select a node directly in the Figma desktop app (no URL required)
• IMPORTANT: The Figma component must be published to a team library. Code Connect only works with published components or component sets.
• Access to the project codebase for component scanning

Required Workflow

Follow these steps in order. Do not skip steps.

Step 1: Get Node ID and Extract Metadata

Option A: Parse from Figma URL

When the user provides a Figma URL with file key and node ID, first run get_metadata to fetch the node structure and identify all Figma components.

IMPORTANT: When extracting the node ID from a Figma URL, convert the format:

• URL format uses hyphens: node-id=1-2
• Tool expects colons: nodeId=1:2

Parse the Figma URL:

• URL format: https://figma.com/design/:fileKey/:fileName?node-id=1-2
• Extract file key: :fileKey (segment after /design/)
• Extract node ID: 1-2 from URL, then convert to 1:2 for the tool

Note: When using the local desktop MCP (figma-desktop), fileKey is not passed as a parameter to tool calls. The server automatically uses the currently open file, so only nodeId is needed.

Example:

get_metadata(fileKey=":fileKey", nodeId="1:2")

Option B: Use Current Selection from Figma Desktop App (figma-desktop MCP only)

When using the figma-desktop MCP and the user has NOT provided a URL, the tools automatically use the currently selected node from the open Figma file in the desktop app.

Note: Selection-based prompting only works with the figma-desktop MCP server. The remote server requires a link to a frame or layer to extract context. The user must have the Figma desktop app open with a node selected.

This returns:

• Node structure and hierarchy in XML format
• Node types (identify <symbol> nodes as Figma components)
• Node IDs, layer names, positions, and sizes
• Child nodes that may also be components

Identify components: For each node or child node returned, if the type is <symbol>, that indicates it's a Figma component that can be code connected.

Step 2: Check Existing Code Connect Mappings

For each Figma component identified (nodes with type <symbol>), check if it's already code connected using get_code_connect_map.

Example:

get_code_connect_map(fileKey=":fileKey", nodeId="1:2")

If the component is already connected:

• Skip to the next component
• Inform the user that this component is already mapped

If not connected:

• Proceed to Step 3 to analyze the component and create a mapping

Step 3: Get Design Context for Un-Connected Components

For components that are not yet code connected, run get_design_context to fetch detailed component structure.

Example:

get_design_context(fileKey=":fileKey", nodeId="1:2")

This returns:

• Component structure and hierarchy
• Layout properties and styling
• Text content and variants
• Design properties that map to code props

Step 4: Scan Codebase for Matching Component

Using the output from get_design_context, scan the codebase to find a component with similar structure.

What to look for:

• Component names that match or are similar to the Figma component name
• Component structure that aligns with the Figma hierarchy
• Props that correspond to Figma properties (variants, text, styles)
• Files in typical component directories (src/components/, components/, ui/, etc.)

Search strategy:

1. Search for component files with matching names
2. Read candidate files to check structure and props
3. Compare the code component's props with Figma design properties
4. Detect the programming language (TypeScript, JavaScript) and framework (React, Vue, etc.)
5. Identify the best match based on structural similarity, weighing:
   • Prop names and their correspondence to Figma properties
   • Default values that match Figma defaults
   • CSS classes or style objects
   • Descriptive comments that clarify intent
6. If multiple candidates are equally good, pick the one with the closest prop-interface match and document your reasoning in a 1–2 sentence comment before your tool call

Example search patterns:

• If Figma component is "PrimaryButton", search for Button.tsx, PrimaryButton.tsx, Button.jsx
• Check common component paths: src/components/, app/components/, lib/ui/
• Look for variant props like variant, size, color that match Figma variants

Step 5: Offer Code Connect Mapping

Present your findings to the user and offer to create the Code Connect mapping.

What to communicate:

• Which code component you found that matches the Figma component
• File path of the component
• Component name
• Language and framework detected

Example message:

I found a matching component in your codebase:
- File: src/components/Button.tsx
- Component: Button
- Language: TypeScript/JavaScript
- Framework: React

Would you like me to create a Code Connect mapping for this component?

If no exact match is found:

• Show the 2 closest candidates
• Explain the differences
• Ask the user to confirm which component to use or provide the correct path

Step 6: Create the Code Connect Mapping

If the user accepts, run add_code_connect_map to establish the connection.

Tool parameters:

add_code_connect_map(
  nodeId="1:2",
  source="src/components/Button.tsx",
  componentName="Button",
  clientLanguages="typescript,javascript",
  clientFrameworks="react"
)

Key parameters:

• nodeId: The Figma node ID (with colon format: 1:2)
• source: Path to the code component file (relative to project root)
• componentName: Name of the component to connect (e.g., "Button", "Card")
• clientLanguages: Comma-separated list of languages (e.g., "typescript,javascript", "javascript")
• clientFrameworks: Framework being used (e.g., "react", "vue", "svelte", "angular")
• label: The framework or language label for this Code Connect mapping. Valid values include:
  • Web: 'React', 'Web Components', 'Vue', 'Svelte', 'Storybook', 'Javascript'
  • iOS: 'Swift UIKit', 'Objective-C UIKit', 'SwiftUI'
  • Android: 'Compose', 'Java', 'Kotlin', 'Android XML Layout'
  • Cross-platform: 'Flutter'

Step 7: Repeat for All Un-Connected Components

After successfully connecting one component, return to Step 2 and repeat the process for all other un-connected Figma components identified in the node tree from Step 1.

Workflow for multiple components:

1. From the metadata obtained in Step 1, identify all nodes with type <symbol>
2. For each component node:
   • Check if already code connected (Step 2)
   • If not connected, proceed with Steps 3-6
   • Track which components have been processed
3. After processing all components, provide a summary:
   • Total components found
   • Components successfully connected
   • Components skipped (already connected)
   • Components that could not be connected (with reasons)

Example summary:

Code Connect Summary:
- Total components found: 5
- Successfully connected: 3
  - Button (1:2) → src/components/Button.tsx
  - Card (1:5) → src/components/Card.tsx
  - Input (1:8) → src/components/Input.tsx
- Already connected: 1
  - Icon (1:3) → src/icons/Icon.tsx
- Could not connect: 1
  - CustomWidget (1:10) - No matching component found in codebase

Examples

Example 1: Connecting a Button Component

User says: "Connect this Figma button to my code: https://figma.com/design/kL9xQn2VwM8pYrTb4ZcHjF/DesignSystem?node-id=42-15"

Actions:

1. Parse URL: fileKey=kL9xQn2VwM8pYrTb4ZcHjF, nodeId=42-15 (from URL)
2. Convert node ID: 42-15 → 42:15
3. Run get_metadata(fileKey="kL9xQn2VwM8pYrTb4ZcHjF", nodeId="42:15") to get node structure
4. Metadata shows: Node type is <symbol> (Figma component), name is "Button"
5. Run get_code_connect_map(fileKey="kL9xQn2VwM8pYrTb4ZcHjF", nodeId="42:15") to check existing mappings
6. Result: No existing mapping found
7. Run get_design_context(fileKey="kL9xQn2VwM8pYrTb4ZcHjF", nodeId="42:15") to get detailed structure
8. Design context shows: Button component with variant (primary/secondary) and size (sm/md/lg) properties
9. Search codebase for Button components: Find src/components/Button.tsx
10. Read Button.tsx and confirm it has variant and size props
11. Offer mapping: "I found Button.tsx with matching variant and size props. Connect?"
12. User confirms: "Yes"
13. Detect that it's a TypeScript React component
14. Run add_code_connect_map(nodeId="42:15", source="src/components/Button.tsx", componentName="Button", clientLanguages="typescript,javascript", clientFrameworks="react")

Result: Figma button component is now connected to the code Button component.

Example 2: Multiple Candidates Scenario

User says: "Connect this card: https://figma.com/design/pR8mNv5KqXzGwY2JtCfL4D/Components?node-id=10-50"

Actions:

1. Parse URL: fileKey=pR8mNv5KqXzGwY2JtCfL4D, nodeId=10-50 → convert to 10:50
2. Run get_metadata(fileKey="pR8mNv5KqXzGwY2JtCfL4D", nodeId="10:50") to get node structure
3. Metadata shows: Node type is <symbol> (Figma component), name is "ProductCard"
4. Run get_code_connect_map(fileKey="pR8mNv5KqXzGwY2JtCfL4D", nodeId="10:50") to check existing mappings
5. Result: No existing mapping found
6. Run get_design_context(fileKey="pR8mNv5KqXzGwY2JtCfL4D", nodeId="10:50")
7. Design context shows: Card with title, description, image, and action button
8. Search codebase: Find two candidates:
   • src/components/Card.tsx (basic card)
   • src/components/ProductCard.tsx (card with image and CTA)
9. Read both files and compare structure
10. Present to user: "Found two card components:

• Card.tsx: Basic card with title and description
• ProductCard.tsx: Card with image, title, description, and action button (closer match)

Which should I connect?"

11. User: "ProductCard.tsx"
12. Detect that it's a TypeScript React component
13. Run add_code_connect_map(nodeId="10:50", source="src/components/ProductCard.tsx", componentName="ProductCard", clientLanguages="typescript,javascript", clientFrameworks="react")

Result: User-selected ProductCard component is successfully connected to the Figma design.

Example 3: Component Needs Creation

User says: "Connect this icon: https://figma.com/design/8yJDMeWDyBz71EnMOSuUiw/Icons?node-id=5-20"

Actions:

1. Parse URL: fileKey=8yJDMeWDyBz71EnMOSuUiw, nodeId=5-20 → convert to 5:20
2. Run get_metadata(fileKey="8yJDMeWDyBz71EnMOSuUiw", nodeId="5:20") to get node structure
3. Metadata shows: Node type is <symbol> (Figma component), name is "CheckIcon"

5. Result: No existing mapping found
6. Run get_design_context(fileKey="8yJDMeWDyBz71EnMOSuUiw", nodeId="5:20")
7. Design context shows: CheckIcon with color and size variants
8. Search codebase for CheckIcon: No matches found
9. Search for generic Icon components: Find src/icons/ directory with other icons
10. Report to user: "I couldn't find a CheckIcon component, but I found an icons directory at src/icons/. Would you like to:

• Create a new CheckIcon.tsx component first, then connect it
• Connect to a different existing icon
• Provide the path to the CheckIcon if it exists elsewhere"

11. User provides path: "src/icons/CheckIcon.tsx"
12. Detect language and framework from the file
13. Run add_code_connect_map(nodeId="5:20", source="src/icons/CheckIcon.tsx", componentName="CheckIcon", clientLanguages="typescript,javascript", clientFrameworks="react")

Result: CheckIcon component is successfully connected to the Figma design.

Best Practices

Proactive Component Discovery

Don't just ask the user for the file path — actively search their codebase to find matching components. This provides a better experience and catches potential mapping opportunities.

Accurate Structure Matching

When comparing Figma components to code components, look beyond just names. Check that:

• Props align (variant types, size options, etc.)
• Component hierarchy matches (nested elements)
• The component serves the same purpose

Clear Communication

When offering to create a mapping, clearly explain:

• What you found
• Why it's a good match
• What the mapping will do
• How props will be connected

Handle Ambiguity

If multiple components could match, present options rather than guessing. Let the user make the final decision about which component to connect.

Graceful Degradation

If you can't find an exact match, provide helpful next steps:

• Show close candidates
• Suggest component creation
• Ask for user guidance

Common Issues and Solutions

Issue: "Failed to map node to Code Connect. Please ensure the component or component set is published to the team library"

Cause: The Figma component is not published to a team library. Code Connect only works with published components. Solution: The user needs to publish the component to a team library in Figma:

1. In Figma, select the component or component set
2. Right-click and choose "Publish to library" or use the Team Library publish modal
3. Publish the component
4. Once published, retry the Code Connect mapping with the same node ID

Issue: No matching component found in codebase

Cause: The codebase search did not find a component with a matching name or structure. Solution: Ask the user if the component exists under a different name or in a different location. They may need to create the component first, or it might be located in an unexpected directory.

Issue: Code Connect map creation fails with "component not found"

Cause: The source file path is incorrect, the component doesn't exist at that location, or the componentName doesn't match the actual export. Solution: Verify the source path is correct and relative to the project root. Check that the component is properly exported from the file with the exact componentName specified.

Issue: Wrong language or framework detected

Cause: The clientLanguages or clientFrameworks parameters don't match the actual component implementation. Solution: Inspect the component file to verify the language (TypeScript, JavaScript) and framework (React, Vue, etc.). Update the parameters accordingly. For TypeScript React components, use clientLanguages="typescript,javascript" and clientFrameworks="react".

Issue: Code Connect mapping fails with URL errors

Cause: The Figma URL format is incorrect or missing the node-id parameter. Solution: Verify the URL follows the required format: https://figma.com/design/:fileKey/:fileName?node-id=1-2. The node-id parameter is required. Also ensure you convert 1-2 to 1:2 when calling tools.

Issue: Multiple similar components found

Cause: The codebase contains multiple components that could match the Figma component. Solution: Present all candidates to the user with their file paths and let them choose which one to connect. Different components might be used in different contexts (e.g., Button.tsx vs LinkButton.tsx).

Understanding Code Connect

Code Connect establishes a bidirectional link between design and code:

For designers: See which code component implements a Figma component For developers: Navigate from Figma designs directly to the code that implements them For teams: Maintain a single source of truth for component mappings

The mapping you create helps keep design and code in sync by making these connections explicit and discoverable.
