A TypeScript-based workflow automation tool designed to accelerate high-fidelity fintech prototyping by programmatically injecting dynamic transaction data into the Figma canvas
Ever spent 3 hours manually exporting 200 Figma frames into different sizes for iOS/Android/Web? This plugin automates that nightmare—and a lot more.
🛠️ What It Does (The Cool Parts)
- Batch asset export: Select frames → Click button → Get PNG/SVG/PDF in 1x/2x/3x resolutions (iOS style)
- Design token extraction: Auto-generate CSS variables from Figma styles (
--color-primary: #3B82F6;) - Component auditing: Find all instances of "Button_Old" so you can migrate to "Button_New" without hunting manually
- Accessibility checks: Flag text with insufficient contrast ratios (WCAG AA compliance)
- Version comparison: Diff two Figma files visually—highlight what changed between design iterations
🧠 Technical Implementation
Figma plugins run in a sandboxed iframe with a dual-process architecture:
| UI Thread (React) | Renders settings panel, handles user input |
| Plugin Thread (figma.* APIs) | Accesses document nodes, exports images, modifies layers |
The tricky part: Communication between threads happens via postMessage()—need to serialize large image data without blocking UI.
// Efficient batch export (parallelized)
const exports = await Promise.all(
selectedFrames.map(frame =>
frame.exportAsync({ format: 'PNG', constraint: { type: 'SCALE', value: 2 } })
)
);
🎯 Real-World Impact
Design team feedback: "Saved 15 hours/week on asset handoffs. Now we actually have time to design instead of clicking export buttons." 🎉
