thedixitjain Figma Architecture Variants
Overview
Three proven architecture patterns for Figma integrations, based on the two primary Figma APIs: the REST API (external tools) and the Plugin API (in-editor experiences).
Prerequisites
- Clear use case requirements
- Understanding of Figma REST API vs Plugin API differences
Instructions
Step 1: Choose Your Architecture
| Architecture | API Used | Best For | Hosting |
|---|---|---|---|
| CLI/Script | REST API | Design token sync, asset export | None (runs locally or in CI) |
| Webhook Service | REST API | Real-time automation, Slack bots | Server/serverless |
| Figma Plugin | Plugin API | In-editor tools, design linting | Runs in Figma desktop app |
Variant A: CLI Script (Simplest)
Use case: Extract design tokens, export icons, sync to code
Developer runs script

{
"scripts": {
"figma:tokens": "tsx scripts/extract-tokens.ts",
"figma:icons": "tsx scripts/export-icons.ts",
"figma:sync": "npm run figma:tokens && npm run figma:icons"
}
}
Pros: Zero infrastructure, runs in CI, easy to debug Cons: Not real-time, manual trigger, no webhook support
Variant B: Webhook Service (Event-Driven)
Use case: Auto-sync on file save, Slack notifications, build triggers

// Minimal webhook service (Express)
const app = express();
app.post('/webhooks/figma', express.json(), verifyPasscode, (req, res) => {
res.status(200).json({ received: true });
processEvent(req.body); // async
});
app.get('/health', healthCheck);
app.listen(process.env.PORT || 3000);
Pros: Real-time, event-driven, no polling waste Cons: Requires hosting, HTTPS endpoint, webhook management
Variant C: Figma Plugin (In-Editor)
Use case: Design linting, component generation, data population
┌─────────────────────────────────────────┐

// manifest.json
{
"name": "My Design Linter",
"id": "1234567890",
"api": "1.0.0",
"main": "dist/code.js",
"ui": "dist/ui.html",
"editorType": ["figma"],
"permissions": ["currentuser"]
}
// code.ts -- Plugin API (runs in Figma sandbox)
// Access the document directly -- no REST API needed
const page = figma.currentPage;
const frames = page.findAll(n => n.type === 'FRAME');
// Create nodes programmatically
const rect = figma.createRectangle();
rect.resize(200, 100);
rect.fills = [{ type: 'SOLID', color: { r: 1, g: 0.5, b: 0 } }];
page.appendChild(rect);
// Read component properties
const components = page.findAll(n => n.type === 'COMPONENT') as ComponentNode[];
for (const comp of components) {
console.log(`${comp.name}: ${comp.width}x${comp.height}`);
}
Pros: Direct document access, instant feedback, rich UI Cons: Only works in Figma desktop, no server-side processing, sandboxed
Step 2: Decision Matrix
| Factor | CLI Script | Webhook Service | Figma Plugin |
|---|---|---|---|
| Real-time | No | Yes | Yes (in-editor) |
| Infrastructure | None | Server/serverless | None |
| CI/CD integration | Natural | Via webhook | Not applicable |
| User interaction | No | No | Yes |
| API used | REST API | REST API | Plugin API |
| File modification | No (read-only) | No (read-only) | Yes (full access) |
| Figma app required | No | No | Yes |
| Auth | PAT | PAT + webhook passcode | None (runs in Figma) |
Step 3: Hybrid Architecture
Many production systems combine variants:
CLI (CI) ← Scheduled token sync (daily at 9 AM)
+
Webhook Service ← Real-time notifications (Slack, rebuild triggers)
+
Figma Plugin ← In-editor design linting and data population
Output
- Architecture variant selected based on use case
- Data flow documented
- API choice justified (REST vs Plugin)
- Implementation skeleton provided
Error Handling
| Issue | Cause | Solution |
|---|---|---|
| CLI too slow | Full file fetch | Use depth=1 and /nodes |
| Webhook not firing | No HTTPS | Deploy to platform with TLS |
| Plugin sandbox limits | Heavy computation | Offload to REST API via fetch in UI iframe |
| Wrong variant choice | Over-engineering | Start with CLI, add webhook when needed |
Examples
Pick a variant with the Step 2 decision matrix — two common calls:
- Nightly design-token sync into a repo → Variant A (CLI script in CI). No server to run; rate limits are a non-issue at one run per day.
- Slack notification within seconds of a library publish → Variant B (webhook service subscribed to
LIBRARY_PUBLISH). Polling would burn the rate budget; a plugin can't run headless.
Smoke-test the Variant B receiver locally before registering the webhook:
curl -s -X POST localhost:3000/figma/webhook \
-H 'Content-Type: application/json' \
-d '{"event_type":"PING","passcode":"test-passcode"}'
# 200 {"ok":true}
