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 🙏

Readme

This is just a fork of vue-qrcode-reader to support switching cameras using device id

A set of Vue.js components, allowing you to detect and decode QR codes, without leaving the browser.

  • :movie_camera: QrcodeStream accesses the device camera and continuously scans incoming frames.
  • :put_litter_in_its_place: QrcodeDropZone renders to an empty region where you can drag-and-drop images to be decoded.
  • :open_file_folder: QrcodeCapture is a classic file upload field, instantly scanning all files you select.

All components are responsive. Beyond that, close to zero styling. Make them fit your layout. Usage is simple and straight forward:

<qrcode-stream @decode="onDecode"></qrcode-stream>
methods: {
  onDecode (decodedString) {
    // ...
  }
}

Screenshots

Installation :package:

With NPM

Run

npm install @jyotirmay/vue-qrcode-reader-extended

You can import the components independantly

import { QrcodeStream, QrcodeDropZone, QrcodeCapture } from '@jyotirmay/vue-qrcode-reader-extended'

const MyComponent = {

  components: {
    QrcodeStream,
    QrcodeDropZone,
    QrcodeCapture
  },

  // ...
))

or register all of them globally right away

import Vue from "vue";
import VueQrcodeReader from "@jyotirmay/vue-qrcode-reader-extended";

Vue.use(VueQrcodeReader);

Without NPM

Include the following JS file:

https://unpkg.com/vue-qrcode-reader/dist/VueQrcodeReader.umd.min.js

Make sure to include it after Vue:

<script src="./vue.js"></script>
<script src="./VueQrcodeReader.umd.min.js"></script>

All components are automatically registered globally. Use kebab-case to reference them in your templates:

<qrcode-stream></qrcode-stream>
<qrcode-drop-zone></qrcode-drop-zone>
<qrcode-capture></qrcode-capture>

Troubleshooting :zap:

The wrong camera is picked by default. Can I set it explicitly?

Modern devices sometimes have multiple rear cameras. Not all are optimal for scanning QR codes. For example wide angle, infrared and virtual cameras. With the current web API it's hard to pick the right camera automatically. It's technically possible to let the user make that decision. For example by displaying list of installed cameras and letting the user select the right one. However, this is a user experience trade-off. Native QR code reader applications don't face this trade-off. That's why we want to find a different solution.

Please create a GitHub issue from the wrong camera selected template and follow the instructions in the text.

I don't see the camera when using QrcodeStream.

  • Check if it works on the demo page. Especially the Decode All demo, since it renders error messages. If you see errors, consult the docs to understand their meaning.
    • The demo works but it doesn't work in my project: Listen for the init event to investigate errors.
    • The demo doesn't work: Carefully review the Browser Support section above. Maybe your device is just not supported.

I'm running a dev server on localhost. How to test on my mobile device without HTTPS?

  • If your setup is Desktop Chrome + Android Chrome, use Remote Debugging which allows your Android device to access your local server as localhost.
  • Otherwise use a reverse proxy like ngrok or serveo to temporarily make your local server publicly available with HTTPS.
  • There are also loads of serverless/static hosting services that have HTTPS enabled by default and where you can deploy your web app for free (e.g. GitHub Pages, GitLab Pages, Google Firebase, Netlify, Heroku, ZEIT Now, ...)

Some of my QR codes are not being detected.

  • Make sure, there is some white border around the QR code.
  • Color inverted QR codes are not supported (dark background, light foreground).
  • Model 1 QR codes are also not supported.

Thanks :pray:
