qr-scanner | Lightweight Javascript QR Code Scanner

After updating my npm packages, some of the imports from the 'vue' module started showing errors:

TS2305: Module '"../../node_modules/vue/dist/vue"' has no exported member 'X'

where X is nextTick, onMounted, ref, watch etc. When serving the project, Vue says it's "failed to compile". WebStorm actually recognizes the exports, suggests them and shows types, but the error is shown regardless. Some exports like computed and defineComponent work just fine.

What I've tried:

• Rollback to the previously used Vue version "3.2.2" > "3.0.11". It makes the abovementioned type errors disappear, but the app stops working entirely, showing lots of TypeError: Object(...) is not a function errors in console and not rendering the app at all. In the terminal, some new warnings are introduced: "export 'X' (imported as '_X') was not found in 'vue' where X is createElementBlock, createElementVNode, normalizeClass and normalizeStyle.
• Rollback other dependencies. None of the ones that I tried helped fix the problem, unfortunately.
• Manually declare the entirety of 'vue' module. We can declare the 'vue' module exports in shims-vue.d.ts, and it actually makes the errors disappear, however, this seems like a terrible, time-consuming workaround, so I would opt out for a better solution if possible.

I get blank screen when using capacitor QrCode package.

I'm using this to build a simple QrCode scanner but I keep getting a black screen when calling the scan() method

Firebase 8 seems to have a problem. Firestore was not able to get a collection or doc element in case of error '''this.afs.collection is not a function'''. I understand, afs seems to be something like not initialized. But its set as provider in 'app.module.ts' and its not null.

Then I installed all I found, like angular/fire 6.1.5, firebase 8, ionic-native/firebase 5.36, firestore-x, firebase-authentication, cordova-plugin-firebase 2.0.5, cordova-plugin-firebase-authentication, cordova-plugin-firebasex. It feels overloaded but I still can not get the function, even if afs instance is not null.

Any ideas?

I am trying to build react prod docker container with Azure DevOps pipelines. After I upgrade my build environment and code, Pipeline failed. After some research I add "--node-flags --max-old-space-size=8192" statement my build command. But it didn't matter. I also try tried relevant node containers for a build, it didn't work.

I am trying to implement QR scanner to scan for QR code using angular2-qrscanner. After doing what it says in the documentation, I am gettting the error

"Cannot read property 'getMediaDevices' of undefined "

on the console. These are my codes.

Problem : So I'm using this npm package react-qr-scanner to scan QR codes in my PWA. Now this is a react based package. The react component(just an example) is like:

I'm using the https://github.com/nimiq/qr-scanner for scanning QR codes. It uses a smaller rectangle from the whole video for scanning the codes.

This rectangle is a centered square of two thirds of the video width or height, whichever is smaller.

I want to show a div with red border to show the user where is this scan region. How can I do it in css without calculating the top, left, width and height in JS?

I'm experimenting with svelte using it's template (https://github.com/sveltejs/template/) as starting point.

And I wanted to scan qr codes with https://github.com/nimiq/qr-scanner, but on my pc I don't have a webcam and my phone doesn't want to start the qrScanner because the page isn't served from https.

when I run npm run dev I get:

Here is my TS code where StartScannig() is used to start the qrscanner and Scan() is for the barcode scanner.
