Skia Canvas: Browser-Less Implementation of the HTML Canvas Drawing API for Node

1. Skia

   1 59 9,614 9.9 C++

   Skia is a complete 2D graphic library for drawing Text, Geometries, and Images.

   

   If you're interested in node-compatible canvas implementations, there are several:

   * canvaskit-wasm, from the skia project. I don't think it's gpu-accelerated: https://github.com/google/skia/tree/main/modules/canvaskit/n...

   * @napi-rs/canvas. This is the fastest binding: https://github.com/Brooooooklyn/canvas?tab=readme-ov-file#pe...

   * node-canvas. Uses Cairo instead of Skia: https://github.com/Automattic/node-canvas

3. windowjs

   2 11 2,255 4.4 JavaScript

   Window.js is an open-source Javascript runtime for desktop graphics programming.

   

   https://windowjs.org is a very similar concept -- it wraps Skia and exposes it as the Canvas API, but also embeds v8 for a very small runtime instead of using Node.

   It was my first open-source project, released about 3 years ago.

   I had plans to also expose WebGL, audio, etc and make it a viable platform for Javascript-based games on desktop.

   Life and other projects happened instead, and development was discontinued. Happy to see this project also making Canvas accessible outside the browser!

4. SWIG

   3 28 5,926 9.7 C++

   SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages.

   

   I understand that a Skia Canvas should work with almost any programming language with just bindings [1]. I don't see anything in particular with Node.

5. jimp

   4 9 14,278 9.0 TypeScript

   An image processing library written entirely in JavaScript for Node, with zero external or native dependencies.

   

   How is it different from jimp?

   https://jimp-dev.github.io/jimp/

   Maybe there are some killer features?

6. lacqit

   5 1 1 - Objective-C

   Obj-C utility library

   

   I'm not claiming I implemented everything from scratch. Since it was a Mac OS X Cocoa app, it would just call the APIs available on that platform, like Apple's original Canvas implementation in WebKit.

   Also since this was a video application running custom scripts written specifically for that host app, there wasn't a big worry about exact compatibility with any other Canvas-using code.

   Anyway, here's the old code that doesn't look like there's anything interesting going on:

   Looks like I misremembered — it's using Cairo rather than CoreGraphics. I don't remember why that was.

7. opengraph

   6 177 230 0.0 Python

   A python module to parse the Open Graph Protocol

   How would you render FRED charts with e.g. headless node to generate PNG (or SVG) images for og:image , schema:image , and schema.org/thumbnailUrl so that shared URLs to FRED charts have a PNG (or SVG) image in their social share cards?

   OpenGraph: https://ogp.me/

   schema:thumbnailUrl: https://schema.org/thumbnailUrl

8. engine

   7 53 7,532 10.0 C++

   Discontinued The Flutter engine (by flutter)

   

   Impeller - Flutter’s rendering library that replaces Skia on iOS and Android - is working on a C API: https://github.com/flutter/engine/blob/main/impeller/toolkit...

10. tela.js

    8 1 6 9.2 JavaScript

    Graphic library from scratch, with reference implementation of computer graphics algorithms

    

    I made something similar for node/web, not so complete, but good.

11. canvas

    9 8 1,884 9.1 Rust
