Learn FIGMA-PLUGIN-API with Real Code Examples

Updated Nov 26, 2025

Explain

The API provides a structured way to read and manipulate Figma documents.

Plugins can create, modify, and delete nodes such as frames, rectangles, text, and components.

It supports UI elements via HTML/CSS/JS panels rendered inside the Figma plugin window.

Enables communication between plugin code (main thread) and UI thread (frontend panel).

Supports asynchronous operations and event-driven architecture for responsive plugins.

Core Features

Node manipulation (create, read, update, delete)

Selection API to read user-selected nodes

Event listeners for document changes

Plugin UI API for custom interface panels

Storage API for persisting plugin data

Basic Concepts Overview

Node: any object in Figma (frame, component, shape, text)

Selection: nodes currently selected by user

Properties: width, height, fills, strokes, constraints, etc.

UI panel: HTML/CSS/JS frontend for plugin interaction

Message passing: communication between main and UI threads

Project Structure

manifest.json - plugin metadata and permissions

code/ - main plugin logic (JS/TS)

ui/ - optional HTML/CSS/JS panel

assets/ - images, icons, fonts for plugin

tests/ - automated or manual test scripts

Building Workflow

Define plugin goal (e.g., rename layers, generate charts)

Create manifest.json with permissions

Develop main plugin script for Figma operations

Optionally create plugin UI panel

Test, debug, and iterate within Figma

Difficulty Use Cases

Beginner: simple layer manipulations

Intermediate: batch node operations

Advanced: interactive UI with real-time updates

Expert: complex automation workflows with external APIs

Architect: enterprise-level plugins for team-wide design systems
