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 🙏

Straightforward DOM implementation to make SVG.js run headless on Node.js

While this dom implementation was designed to run svg.js on node, it now is much more feature complete and can be used by anyone needing an xml, svg or html dom.

Get started with svg.js v3.x

for older versions of svg.js checkout older versions of svgdom

npm install @svgdotjs/svg.js svgdom
import { createSVGWindow } from 'svgdom'
import { SVG, registerWindow } from '@svgdotjs/svg.js'

// returns a window with a document and an svg root node
const window = createSVGWindow()
const document = window.document

// register window and document
registerWindow(window, document)

// create canvas
const canvas = SVG(document.documentElement)

// use svg.js as normal
canvas.rect(100, 100).fill('yellow').move(50,50)

// get your svg as string
console.log(canvas.svg())
// or
console.log(canvas.node.outerHTML)

Create an HTML Dom or XML Dom

// create HTML window with a document and an html root node
import { createHTMLWindow } from 'svgdom'
const window = createHTMLWindow()

// create XML window with a document and a given xml root node
import { createWindow } from 'svgdom'
const window = createWindow(namespaceURI, rootNode)
// e.g. createWindow('http://www.w3.org/1998/Math/MathML', 'math')

Use svgdom as cjs module

svgdom is used best as esm module. However, if you still require cjs, you have to import the module via the async import function:

const main = async () => {
    const { createSVGWindow } = await import('svgdom')
}
main()

Fonts

In order to calculate bounding boxes for text the font needs to be loaded first. svgdom loads Open Sans-Regular by default when no font file for the specified font was found. The following options must be set in order to load your own fonts:

import { config } from 'svgdom'
config.
    // your font directory
    .setFontDir('./fonts')
    // map the font-family to the file
    .setFontFamilyMappings({'Arial': 'arial.ttf'})
    // you can preload your fonts to avoid the loading delay
    // when the font is used the first time
    .preloadFonts()

// Alternatively you can import the functions itself and use them
const {setFontDir, setFontFamilyMappings, preloadFonts} = require('svgdom')
setFontDir('./fonts')
setFontFamilyMappings({'Arial': 'arial.ttf'})
preloadFonts()

Limitations

Almost all functions of svg.js work properly with svgdom. However there are a few known limitations:

  • font properties like bold, italic... are only supported when you explicitely load that font e.g.
    setFontFamilyMappings({'Arial-italic': 'arial_italic.ttf'})
  • querySelector only supports the following pseudo classes:
    • first-child
    • last-child
    • nth-child
    • nth-last-child
    • first-of-type
    • last-of-type
    • nth-of-type
    • nth-last-of-type
    • only-child
    • only-of-type
    • root
    • not
    • matches
    • scope
  • special chars in attribute values: # and . are allowed but things like : or [] will break the selector

Using svgdom in your own projects

Albeit this dom implementation aims to work with svgjs, it is of course possible to use it in your own projects. Keep in mind, that some functions are just not needed in svgjs and therefore not implemented or tested. If you need a certain feature don't hesistate to open an issue or submit a pull request.

Last thing to say: childNodes is an array! (yet)
