## What it is
A Node.js library implementing the HTML Canvas drawing API on top of Google's Skia graphics engine, with a Rust/N-API core. It supports bitmap and vector output (PNG, JPEG, WEBP, PDF, SVG), multi-threaded async rendering, GUI windows, and rich typography.

## Use cases
- render images server-side in node
- generate pdf and svg files from canvas drawings
- replace node-canvas with a faster gpu-backed canvas
- draw charts or graphics for aws lambda or vercel functions
- manipulate bezier paths with boolean operations
- render text with variable fonts and opentype features
- display an interactive canvas window in a desktop script

## When to choose
- you need browser-identical canvas output in Node.js
- you need vector output like PDF or SVG, not just bitmaps
- you need high-performance multi-threaded rendering or serverless compatibility
- you need advanced typography or path boolean operations

## When to avoid
- you need a pure-JavaScript solution without native binaries
- you target platforms without prebuilt binaries (e.g., unusual libc or architectures)
- you only need simple image processing better served by sharp

## Facets
- artifact type: library
- maturity: active
- function: image-processing, graphics, pdf, gui
- domain: graphics, image-processing, web-development, developer-tools
- platform: windows, serverless
- tags: canvas, skia, vector-graphics, svg, typography, rust-native, server-side-rendering, nodejs, linux, macos
