Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

SVGCanvas

Draw on SVG using Canvas's 2D Context API. A maintained fork of gliffy's canvas2svg.

Demo

https://zenozeng.github.io/svgcanvas/test/

How it works

We create a mock 2d canvas context. Use the canvas context like you would on a normal canvas. As you call methods, we build up a scene graph in SVG.

Usage

import { Context } from "svgcanvas";

const ctx = new Context(500, 500);

// draw your canvas like you would normally
ctx.fillStyle = "red";
ctx.fillRect(100, 100, 100, 100);

// serialize your SVG
const mySerializedSVG = ctx.getSerializedSvg();

Wrapping canvas elements:

import { Context, Element } from "svgcanvas";

const canvas = document.createElement("canvas");
const context2D = canvas.getContext("2d");

// more options to pass into constructor:
const options = {
  height: 2000, // falsy values get converted to 500
  width: 0 / 0, // falsy values get converted to 500
  ctx: context2D, // existing Context2D to wrap around
  enableMirroring: false, // whether canvas mirroring (get image data) is enabled (defaults to false)
  document: undefined, // overrides default document object
};

// Creates a mock canvas context (mocks `context2D` above)
const ctx = new Context(options);

// draw your canvas like you would normally
ctx.fillStyle = "red";
ctx.fillRect(100, 100, 100, 100);

ctx.getSerializedSvg(); // returns the serialized SVG
ctx.getSvg(); // returns the inline svg element

// Creates a mock canvas element (mocks `canvas` above)
const dom = new Element(options);
dom.ctx; // the internal context, via `new Context(options)`
dom.wrapper; // a div with the svg as a child
dom.svg; // the inline svg element
