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 🙏

solid-qr-code

A Solid component to generate QR codes for rendering to the DOM. This package was ported to Solid from the qrcode.react package made by zpao

Installation

npm install solid-qr-code

Usage

solid-qr-code exports three components, supporting rendering as SVG or Canvas. SVG is generally recommended as it is more flexible, but Canvas may be preferable.

All examples are shown using modern JavaScript modules and syntax.

QRCodeSVG

import { render } from 'solid-js/web';
import QRCodeSVG from "solid-qr-code";

import App from './App';

render(() => <QRCodeSVG value="https://solidjs.com/" />, document.getElementById('root') as HTMLElement);

QRCodeCanvas

import { render } from 'solid-js/web';
import QRCodeCanvas from "solid-qr-code";

import App from './App';

render(() => <QRCodeCanvas value="https://solidjs.com/" />, document.getElementById('root') as HTMLElement);

QRCode - DEPRECATED

Note: Usage of this is deprecated as of v3. It is available as the default export for compatiblity with previous versions. The renderAs prop is only supported with this component.

import { render } from 'solid-js/web';
import QRCode from "solid-qr-code";

import App from './App';

render(() => <QRCode value="https://solidjs.com/" renderAs="canvas" />, document.getElementById('root') as HTMLElement);

Available Props

| prop | type | default value | | --------------- | ---------------------------- | ------------- | | value | string | | renderAs | string ('canvas' 'svg') | 'canvas' | | size | number | 128 | | bgColor | string (CSS color) | "#FFFFFF" | | fgColor | string (CSS color) | "#000000" | | level | string ('L' 'M' 'Q' 'H') | 'L' | | includeMargin | boolean | false | | imageSettings | object (see below) | |

imageSettings

| field | type | default value | | -------- | -------- | ----------------- | | src | string | | x | number | none, will center | | y | number | none, will center | | height | number | 10% of size | | width | number | 10% of size |

Custom Styles

solid-qr-code will pass through any additional props to the underlying DOM node (<svg> or <canvas>). This allows the use of inline style or custom className to customize the rendering. One common use would be to support a responsive layout.

Note: In order to render QR Codes in <canvas> on high density displays, we scale the canvas element to contain an appropriate number of pixels and then use inline styles to scale back down. We will merge any additional styles, with custom height and width overriding our own values. This allows scaling to percentages but if scaling beyond the size, you will encounter blurry images. I recommend detecting resizes with something like a solid version of react-measure to detect and pass the appropriate size when rendering to <canvas>.

Encoding Mode

solid-qr-code supports encoding text only, in a single segment. The encoding library being used does minimal detection to determine if the text being encoded can follow an optimized path for Numeric or Alphanumeric modes, allowing for more data to be encoded. Otherwise, it will encode following Byte mode. This mode includes supports multi-byte Unicode characters such as Kanji, however it does not support the optimized Kanji encoding mode.
