Link your Figma components to live code

Reads your Figma components and codebase, then writes and maintains the .figma.ts files that keep design and code in sync—so devs see the real component when reviewing designs.

Best for: Design and engineering teams that want Figma to show the actual code implementation, not a screenshot.

# Code Connect

## Overview

Create Code Connect template files (`.figma.ts`) that map Figma components to code snippets. Given a Figma URL, follow the steps below to create a template.

> **Note:** This project may also contain parser-based `.figma.tsx` files (using `figma.connect()`, published via CLI). This skill covers **templates files only** — `.figma.ts` files that use the MCP tools to fetch component context from Figma.

## Prerequisites

- **Figma MCP server must be connected** — verify that Figma MCP tools (e.g., `get_code_connect_suggestions`) are available before proceeding. If not, guide the user to enable the Figma MCP server and restart their MCP client.
- **Components must be published** — Code Connect only works with components published to a Figma team library. If a component is not published, inform the user and stop.
- **Organization or Enterprise plan required** — Code Connect is not available on Free or Professional plans.
- **URL must include `node-id`** — the Figma URL must contain the `node-id` query parameter.
- **TypeScript types** — for editor autocomplete and type checking in `.figma.ts` files `@figma/code-connect/figma-types` must be added to `types` in `tsconfig.json`:
  ```json
  {
    "compilerOptions": {
      "types": ["@figma/code-connect/figma-types"]
    }
  }
  ```

## Step 1: Parse the Figma URL

Extract `fileKey` and `nodeId` from the URL:

| URL Format | fileKey | nodeId |
|---|---|---|
| `figma.com/design/:fileKey/:name?node-id=X-Y` | `:fileKey` | `X-Y` → `X:Y` |
| `figma.com/file/:fileKey/:name?node-id=X-Y` | `:fileKey` | `X-Y` → `X:Y` |
| `figma.com/design/:fileKey/branch/:branchKey/:name` | use `:branchKey` | from `node-id` param |

Always convert `nodeId` hyphens to colons: `1234-5678` → `1234:5678`.

**Worked example:**

Given: `https://www.figma.com/design/QiEF6w564ggoW8ftcLvdcu/MyDesignSystem?node-id=4185-3778`
- `fileKey` = `QiEF6w564ggoW8ftcLvdcu`
- `nodeId` = `4185-3778` → `4185:3778`

## Step 2: Discover Unmapped Components

The user may provide a URL pointing to a frame, instance, or variant — not necessarily a component set or standalone component. Call the MCP tool `get_code_connect_suggestions` with:
- `fileKey` — from Step 1
- `nodeId` — from Step 1 (colons format)
- `excludeMappingPrompt` — `true` (returns a lightweight list of unmapped components)

This tool identifies published components in the selection that don't yet have Code Connect mappings.

**Handle the response:**

- **"No published components found in this selection"** — the node contains no published components. Inform the user they need to publish the component to a team library in Figma first, then stop.
- **"All component instances in this selection are already connected to code via Code Connect"** — everything is already mapped. Inform the user and stop.
- **Normal response with component list** — extract the `mainComponentNodeId` for each returned component. Use these resolved node IDs (not the original from the URL) for all subsequent steps. If multiple components are returned (e.g. the user selected a frame containing several different component instances), repeat Steps 3–6 for each one.

## Step 3: Fetch Component Properties

Call the MCP tool `get_context_for_code_connect` with:
- `fileKey` — from Step 1
- `nodeId` — the resolved `mainComponentNodeId` from Step 2
- `clientFrameworks` — determine from `figma.config.json` `parser` field (e.g. `"react"` → `["react"]`)
- `clientLanguages` — infer from project file extensions (e.g. TypeScript project → `["typescript"]`, JavaScript → `["javascript"]`)

For multiple components, call the tool once per node ID.

The response contains the Figma component's **property definitions** — note each property's name and type:
- **TEXT** — text content (labels, titles, placeholders)
- **BOOLEAN** — toggles (show/hide icon, disabled state)
- **VARIANT** — enum options (size, variant, state)
- **INSTANCE_SWAP** — swappable nested instances tied to a specific component (icon, avatar)
- **SLOT** — flexible content regions (freeform layout, mixed children); use `getSlot()` in templates (not the same as INSTANCE_SWAP)

Save this property list — you will use it in Step 5 to write the template.

## Step 4: Identify the Code Component

If the user did not specify which code component to connect:

1. Check `figma.config.json` for `paths` and `importPaths` to find where components live
2. Search the codebase for a component matching the Figma component name. Check common directories (`src/components/`, `components/`, `lib/ui/`, `app/components/`) if `figma.config.json` doesn't specify paths
3. Read candidate files and compare their props interface against the Figma properties from Step 3 — look for matching variant types, size options, boolean flags, and slot props
4. If multiple candidates match, pick the one with the closest prop-interface match and explain your reasoning to the user
5. If no match is found, show the 2 closest candidates and ask the user to confirm or provide the correct path

**Confirm with the user** before proceeding to Step 5. Present the match: which code component you found, where it lives, and why it matches (prop correspondence, naming, purpose).

Read `figma.config.json` for import path aliases — the `importPaths` section maps glob patterns to import specifiers, and the `paths` section maps those specifiers to directories.

Read the code component's source to understand its props interface — this informs how to map Figma properties to code props in Step 5.

## Step 5: Create the Template File (.figma.ts)

### File location

Place the file alongside existing Code Connect templates (`.figma.tsx` or `.figma.ts` files). Check `figma.config.json` `include` patterns for the correct directory. Name it `ComponentName.figma.ts`.

### Template structure

Every template file follows this structure:

```ts
// url=https://www.figma.com/file/{fileKey}/{fileName}?node-id={nodeId}
// source={path to code component from Step 4}
// component={code component name from Step 4}
import figma from 'figma'
const instance = figma.selectedInstance

// Extract properties from the Figma component (see property mapping below)
// ...

export default {
  example: figma.code`<Component ... />`,       // Required: code snippet
  imports: ['import { Component } from "..."'], // Optional: import statements
  id: 'component-name',                         // Required: unique identifier
  metadata: {                                    // Optional
    nestable: true,                              // true = inline in parent, false = show as pill
    props: {}                                    // data accessible to parent templates
  }
}
```

### Property mapping

Use the property list from Step 3 to extract values. For each Figma property type, use the corresponding method:

| Figma Property Type | Template Method | When to Use |
|---|---|---|
| TEXT | `instance.getString('Name')` | Labels, titles, placeholder text |
| BOOLEAN | `instance.getBoolean('Name', { true: ..., false: ... })` | Toggle visibility, conditional props |
| VARIANT | `instance.getEnum('Name', { 'FigmaVal': 'codeVal' })` | Size, variant, state enums |
| INSTANCE_SWAP | `instance.getInstanceSwap('Name')` | Swapped instance for a fixed component slot (then `hasCodeConnect()` / `executeTemplate()`) - do not confuse with the SLOT property below |
| SLOT | `instance.getSlot('Name')` | Freeform slot content only when the Figma property type is **SLOT** 
| (child layer) | `instance.findInstance('LayerName')` | Named child instances without a property |
| (text layer) | `instance.findText('LayerName')` → `.textContent` | Text content from named layers |

**TEXT** — get the string value directly:
```ts
const label = instance.getString('Label')
```

**VARIANT** — map Figma enum values to code values:
```ts
const variant = instance.getEnum('Variant', {
  'Primary': 'primary',
  'Secondary': 'secondary',
})

const size = instance.getEnum('Size', {
  'Small': 'sm',
  'Medium': 'md',
  'Large': 'lg',
})
```

**BOOLEAN** — simple boolean or mapped to values:
```ts
// Simple boolean
const disabled = instance.getBoolean('Disabled')

// Mapped to code values (e.g. when the code prop is an enum, not a boolean)
const size = instance.getBoolean('Show Label', { true: 'large', false: 'small' })
```

**Map Figma properties to code props where there's a valid correspondence.** Figma properties and code props don't always line up 1:1 — some Figma properties map directly (by name, or via the API methods above), others have no code equivalent. Where a mapping exists, use it; where none fits, omit the Figma property rather than invent a code prop. Never emit an attribute whose name doesn't appear in the code component's `Props` interface.

### Exhaustive variant handling

When a VARIANT property has multiple possible values, the `getEnum` mapping **must list every value** returned by `get_context_for_code_connect`. Don't omit values — an unmapped value silently returns `undefined`, producing broken output.

```ts
// WRONG — omits 'Warning', which will render as undefined
const status = instance.getEnum('Status', {
  'Success': 'success',
  'Error': 'error',
})

// CORRECT — every value is mapped
const status = instance.getEnum('Status', {
  'Success': 'success',
  'Error': 'error',
  'Warning': 'warning',
  'Info': 'info',
})
```

When **two or more VARIANT properties combine** to produce different code output, generate exhaustive conditional branches. For example, 2 variants × 2 values = 4 branches:

```ts
const type = instance.getEnum('Type', { 'Filled': 'filled', 'Outlined': 'outlined' })
const status = instance.getEnum('Status', { 'Success': 'success', 'Error': 'error' })

let colorClass
if (type === 'filled' && status === 'success') {
  colorClass = 'bg-green-500 text-white'
} else if (type === 'filled' && status === 'error') {
  colorClass = 'bg-red-500 text-white'
} else if (type === 'outlined' && status === 'success') {
  colorClass = 'bg-transparent border-green-500'
} else if (type === 'outlined' && status === 'error') {
  colorClass = 'bg-transparent border-red-500'
}
```

If the combinations produce **repetitive** output (e.g., `Size` doesn't change the snippet structure — it's just passed through as a prop), a single `getEnum` mapping per variant is sufficient — no need for cross-product branches.

**INSTANCE_SWAP** — access swappable component instances:
```ts
const icon = instance.getInstanceSwap('Icon')
let iconCode
if (icon && icon.type === 'INSTANCE') {
  iconCode = icon.executeTemplate().example
}
```

**SLOT** — `getSlot(propName)` is only valid when the Figma component property reported in Step 3 has type **`SLOT`**. Do not use `getSlot()` for **INSTANCE_SWAP** properties (those use `getInstanceSwap()`). Slots are explicit “content regions” in the component definition, not generic nested instances.

- **Signature:** `getSlot(propName: string): ResultSection[] | undefined`
```ts
// Figma property "Content" must be type SLOT in component properties
const content = instance.getSlot('Content')

export default {
  example: figma.code`<Card>${content}</Card>`,
  // ...
}
```

### Interpolation in tagged templates

When interpolating values in tagged templates, use the correct wrapping:
- **String values** (`getString`, `getEnum`, `textContent`): wrap in quotes → `variant="${variant}"`
- **Instance/section values** (`executeTemplate().example`): wrap in braces → `icon={${iconCode}}`
- **Slot sections** (`getSlot()` result — `ResultSection[] | undefined`): interpolate directly inside `` figma.code`...` `` (same shape as nested snippet sections), e.g. `` figma.code`<Select>${content}</Select>` `` — do not treat as a plain string
- **Boolean bare props**: use conditional → `${disabled ? 'disabled' : ''}`

### Finding descendant layers

When you need to access children that aren't exposed as component properties:

| Method | Use when |
|---|---|
| `instance.getInstanceSwap('PropName')` | Figma property type is **INSTANCE_SWAP** (fixed swapped instance) |
| `instance.getSlot('PropName')` | Figma property type is **SLOT** (freeform content region) |
| `instance.findInstance('LayerName')` | You know the child layer name (no component property) |
| `instance.findText('LayerName')` → `.textContent` | You need text content from a named text layer |
| `instance.findConnectedInstance('id')` | You know the child's Code Connect `id` |
| `instance.findConnectedInstances(fn)` | You need multiple connected children matching a filter |
| `instance.findLayers(fn)` | You need any layers (text + instances) matching a filter |

### Nested configurable instances

A component may contain child instances that are **not exposed as component properties** (no INSTANCE_SWAP) but are still **independently configurable** — they have their own variants, properties, or swap slots. These must be resolved dynamically, not hardcoded.

1. **Check whether the child already has a Code Connect template** — use `get_code_connect_suggestions` or check existing `.figma.ts` files in the project.
2. **If no template exists, create one** for the child so it renders correctly both standalone and when nested.
3. **Reference the child from the parent** using `findInstance()` or `findConnectedInstance()`, then call `executeTemplate()`.

```ts
// Parent template — the Badge child isn't a prop, but it's configurable
const badge = instance.findInstance('Status Badge')
let badgeCode
if (badge && badge.type === 'INSTANCE') {
  badgeCode = badge.executeTemplate().example
}

export default {
  example: figma.code`<Card>${badgeCode}</Card>`,
  // ...
}
```

This applies to icons, badges, labels, and any other nested instance that is configurable by itself — always connect them and render dynamically, never hardcode their content.

### Nested component example

For multi-level nested components or metadata prop passing between templates, see [advanced-patterns.md](references/advanced-patterns.md).

```ts
const icon = instance.getInstanceSwap('Icon')
let iconSnippet
if (icon && icon.type === 'INSTANCE') {
  iconSnippet = icon.executeTemplate().example
}

export default {
  example: figma.code`<Button ${iconSnippet ? figma.code`icon={${iconSnippet}}` : ''}>${label}</Button>`,
  // ...
}
```

### Conditional props

```ts
const variant = instance.getEnum('Variant', { 'Primary': 'primary', 'Secondary': 'secondary' })
const disabled = instance.getBoolean('Disabled')

export default {
  example: figma.code`
    <Button
      variant="${variant}"
      ${disabled ? 'disabled' : ''}
    >
      ${label}
    </Button>
  `,
  // ...
}
```

## Step 6: Validate

Read back the `.figma.ts` file and review it against the following:

- **Property coverage** — every Figma property from Step 3 should be accounted for in the template. Flag any that are missing and ask the user if they were intentionally omitted.
- **Valid, correctly typed code** — all emitted code must be valid and correctly typed against the code component's `Props` interface. Never make up component properties — if a Figma property has no corresponding code prop, omit it rather than invent one.
- **No hardcoded children** — verify that every INSTANCE_SWAP property and child component slot uses the dynamic APIs (`getInstanceSwap()`, `findInstance()`, `findConnectedInstance()`, etc.) with `executeTemplate()`. No slot should contain hardcoded component content.
- **Rules and Pitfalls** — check for the common mistakes listed below (string concatenation of template results, unnecessary `hasCodeConnect()` guards, missing `type === 'INSTANCE'` checks, etc.)
- **Interpolation wrapping** — strings (`getString`, `getEnum`, `textContent`) wrapped in quotes, instance/section values (`executeTemplate().example`) wrapped in braces, slot sections (`getSlot`) interpolated as snippet sections inside `` figma.code`...` ``, booleans using conditionals

If anything looks uncertain, consult [api.md](references/api.md) for API details and [advanced-patterns.md](references/advanced-patterns.md) for complex nesting.

## Inline Quick Reference

### `instance.*` Methods

| Method | Signature | Returns |
|---|---|---|
| `getString` | `(propName: string)` | `string` |
| `getBoolean` | `(propName: string, mapping?: { true: any, false: any })` | `boolean \| any` |
| `getEnum` | `(propName: string, mapping: { [figmaVal]: codeVal })` | `any` |
| `getInstanceSwap` | `(propName: string)` | `InstanceHandle \| null` |
| `getSlot` | `(propName: string)` | `ResultSection[] \| undefined` |
| `getPropertyValue` | `(propName: string)` | `string \| boolean` |
| `findInstance` | `(layerName: string, opts?: SelectorOptions)` | `InstanceHandle \| ErrorHandle` |
| `findText` | `(layerName: string, opts?: SelectorOptions)` | `TextHandle \| ErrorHandle` |
| `findConnectedInstance` | `(codeConnectId: string, opts?: SelectorOptions)` | `InstanceHandle \| ErrorHandle` |
| `findConnectedInstances` | `(selector: (node) => boolean, opts?: SelectorOptions)` | `InstanceHandle[]` |
| `findLayers` | `(selector: (node) => boolean, opts?: SelectorOptions)` | `(InstanceHandle \| TextHandle)[]` |

### InstanceHandle Methods

| Method | Returns |
|---|---|
| `hasCodeConnect()` | `boolean` |
| `executeTemplate()` | `{ example: ResultSection[], metadata: Metadata }` |
| `codeConnectId()` | `string \| null` |

### TextHandle Properties

| Property | Type |
|---|---|
| `.textContent` | `string` |
| `.name` | `string` |

### SelectorOptions

```ts
{ path?: string[], traverseInstances?: boolean }
```

- `traverseInstances: true` — required when the target lives inside another nested instance. Without it, `findInstance`/`findText` only search the current instance's own layers and stop at nested instance boundaries.
- `path: string[]` — disambiguates when multiple descendants share the same layer name. Lists parent layer names that must appear on the path to the target.

**Examples:**

```ts
// Layer hierarchy:
//   A > C (instance) > "mychild"
// "mychild" sits inside nested instance C, so plain findInstance returns ErrorHandle.
instance.findInstance('mychild', { traverseInstances: true })

// Layer hierarchy:
//   A > C (instance) > "mychild"
//   A > D (instance) > "mychild"
// Two "mychild" layers exist — use path to pick the one under C.
instance.findInstance('mychild', { traverseInstances: true, path: ['C'] })
```

**When to reach into a nested instance from a parent template:** only when the parent code component (from Step 4) takes the nested layer as a prop value itself (e.g. `<C show={<B />} />` — A forwards B into C). If the parent just composes C and C renders B internally, resolve C with `executeTemplate()` and let C's own template handle B — don't duplicate B's rendering at the parent level.

### Export Structure

```ts
export default {
  example: figma.code`...`,                      // Required: ResultSection[]
  id: 'component-name',                         // Required: string
  imports: ['import { X } from "..."'],          // Optional: string[]
  metadata: { nestable: true, props: {} }        // Optional
}
```

## Rules and Pitfalls

1. **Never string-concatenate template results.** `executeTemplate().example` is a `ResultSection[]` object, not a string. Using `+` or `.join()` produces `[object Object]`. Always interpolate inside tagged templates: `` figma.code`${snippet1}${snippet2}` ``

2. **Do not use `hasCodeConnect()` guards.** Call `executeTemplate()` directly on any instance after a `type === 'INSTANCE'` check. The runtime handles instances without Code Connect automatically.

   ```ts
   // WRONG — hasCodeConnect() gate drops non-CC instances
   if (icon && icon.type === 'INSTANCE' && icon.hasCodeConnect()) {
     iconCode = icon.executeTemplate().example
   }

   // CORRECT — let the runtime handle all instances
   if (icon && icon.type === 'INSTANCE') {
     iconCode = icon.executeTemplate().example
   }
   ```

3. **Check `type === 'INSTANCE'` before calling `executeTemplate()`.** `findInstance()`, `findConnectedInstance()`, and `findText()` return an `ErrorHandle` (truthy, but not a real node) on failure — not `null`. Always add a type check to avoid crashes: `if (child && child.type === 'INSTANCE') { ... }`

4. **Prefer `getInstanceSwap()` over `findInstance()`** when a component property exists for the slot. `findInstance('Star Icon')` breaks when the icon is swapped to a different name; `getInstanceSwap('Icon')` always works regardless of which instance is in the slot.

5. **Use `getSlot()` only when the Figma property type is `SLOT`.** For **INSTANCE_SWAP** props, use `getInstanceSwap()` (returns an `InstanceHandle`). `getSlot()` returns structured slot sections, not instances — never call `executeTemplate()` on its return value.

6. **Property names are case-sensitive** and must exactly match what `get_context_for_code_connect` returns.

7. **Handle multiple template arrays correctly.** When iterating over children, set each result in a separate variable and interpolate them individually — do not use `.map().join()`:
   ```ts
   // Wrong:
   items.map(n => n.executeTemplate().example).join('\n')

   // Correct — use separate variables:
   const child1 = items[0]?.executeTemplate().example
   const child2 = items[1]?.executeTemplate().example
   export default { example: figma.code`${child1}${child2}` }
   ```

7. **Never hardcode slot or children content.** Always resolve child instances dynamically — use `getInstanceSwap()` for INSTANCE_SWAP properties, `findInstance()`/`findConnectedInstance()` for direct children — and render them via `executeTemplate()`. Never construct JSX from a layer name (e.g., `<StarIcon />`) or guess import paths. If an instance has no Code Connect, omit it — do not add a hardcoded fallback.

   ```ts
   // WRONG — hardcodes the icon from its layer name
   example: figma.code`<Button icon={<StarIcon />}>Submit</Button>`

   // CORRECT — resolves dynamically, works for any swapped icon
   const icon = instance.findInstance('Icon')
   let iconCode
   if (icon && icon.type === 'INSTANCE') {
     iconCode = icon.executeTemplate().example
   }
   example: figma.code`<Button${iconCode ? figma.code` icon={${iconCode}}` : ''}>...</Button>`
   ```

8. **Attempt to represent every Figma property via a code prop.** The code component's `Props` interface (from Step 4) is the authoritative list of attribute names. For each Figma property, figure out the right way to represent it using the API methods from Step 5 — direct name match, value transformation, or whatever fits. If no code prop fits at all, omit it — don't invent a prop name.

## Complete Worked Example

Given URL: `https://figma.com/design/abc123/MyFile?node-id=42-100`

**Step 1:** Parse the URL.
- `fileKey` = `abc123`
- `nodeId` = `42-100` → `42:100`

**Step 2:** Call `get_code_connect_suggestions` with `fileKey: "abc123"`, `nodeId: "42:100"`, `excludeMappingPrompt: true`.
Response returns one component with `mainComponentNodeId: "42:100"`. If the response were empty, stop and inform the user. If multiple components were returned, repeat Steps 3–6 for each.

**Step 3:** Call `get_context_for_code_connect` with `fileKey: "abc123"`, `nodeId: "42:100"` (from Step 2), `clientFrameworks: ["react"]`, `clientLanguages: ["typescript"]`.

Response includes properties:
- Label (TEXT)
- Variant (VARIANT): Primary, Secondary
- Size (VARIANT): Small, Medium, Large
- Disabled (BOOLEAN)
- Has Icon (BOOLEAN)
- Icon (INSTANCE_SWAP)

**Step 4:** Search codebase → find `Button` component. Read its source to confirm props: `variant`, `size`, `disabled`, `icon`, `children`. Import path: `"primitives"`.

**Step 5:** Create `src/figma/primitives/Button.figma.ts`:

```ts
// url=https://figma.com/design/abc123/MyFile?node-id=42-100
// source=src/components/Button.tsx
// component=Button
import figma from 'figma'
const instance = figma.selectedInstance

const label = instance.getString('Label')
const variant = instance.getEnum('Variant', {
  'Primary': 'primary',
  'Secondary': 'secondary',
})
const size = instance.getEnum('Size', {
  'Small': 'sm',
  'Medium': 'md',
  'Large': 'lg',
})
const disabled = instance.getBoolean('Disabled')
const hasIcon = instance.getBoolean('Has Icon')
const icon = hasIcon ? instance.getInstanceSwap('Icon') : null
let iconCode
if (icon && icon.type === 'INSTANCE') {
  iconCode = icon.executeTemplate().example
}

export default {
  example: figma.code`
    <Button
      variant="${variant}"
      size="${size}"
      ${disabled ? 'disabled' : ''}
      ${iconCode ? figma.code`icon={${iconCode}}` : ''}
    >
      ${label}
    </Button>
  `,
  imports: ['import { Button } from "primitives"'],
  id: 'button',
  metadata: { nestable: true }
}
```

**Step 6:** Read back file to verify syntax.
