            You have an incorrect mock for onScan and you are not waiting for results. The action is resolved in the next "tick" not instantly. I think this should work (not tested)

            Good day,

            I found the solution and the following is some of my understanding. This code is work for older version of angular. I am using angular 10, thus, need to define the QRScanner object first. Which is :

            declare var QRScanner: any;

            Or use ( < any > window).QRScanner to get access of the QRScanner plugin.

            Vue 3: Module '"../../node_modules/vue/dist/vue"' has no exported member
            Asked 2022-Jan-24 at 08:38

            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.

            My full list of dependencies:



            Answered 2021-Aug-15 at 13:53

            That named exports from composition API are unavailable means that vue is Vue 2 at some place which has only default export. Since Vue 3 is in dependencies and both lock file and node_modules were refreshed, this means that Vue 2 is nested dependency of some direct dependency.

            The problem needs to be investigated in lock file. It shows that @vue/cli-plugin-unit-jest@4.5.13 depends on vue-jest@3 which depends on vue@2.

            A possible solution is to upgrade @vue/cli-plugin-unit-jest to the latest version, next. The same likely applies to other @vue/cli-* packages because they have matching versions.

            cannot close modal in react

            I have a modal which opens up when I scan a qr Code. After this I set a props to true which tells my Responsemodal to open up. Problem is, I cannot close because this prop is read-only in child component.

            afs.collection is not a function
            Asked 2021-Aug-29 at 18:51

            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?

            Answered 2021-Jul-24 at 08:50

            You cannot use recent versions of MySQL Connector/J on Android, because it uses types and features not available on Android. The specific reason here is that the type com.mysql.cj.MysqlType implements java.sql.SQLType (introduced in Java 8 / JDBC 4.2), and judging by the error this type does not exist in Android. In the past, I have also seen errors related to using named groups in regular expressions, which are (or were) also not supported on Android.

            In general, you shouldn't use JDBC on Android, and it is better to use a REST API to mediate between your Android application and a database. However, if you really want to use MySQL from Android, you will have to use MySQL Connector/J 5.1.x instead of 8.0.x.

            QR Scanner npm library throwing errors for chrome
            Asked 2021-May-31 at 20:53

            I am using the library https://github.com/felipenmoura/qr-code-scanner to implement scanning of the QR codes. I am facing two problems -

            1. Google chrome throws the following error whenever I click the button to trigger. The library works fine on Safari.

            Uncaught (in promise) OverconstrainedError {name: "OverconstrainedError", message: "", constraint: "facingMode"}constraint: "facingMode"message: ""name: "OverconstrainedError"__proto__: OverconstrainedError

            1. The camera feed doesn't work for mobile phones (both safari and chrome). It opens the camera, and doesn't show the live feed, instead it keeps on showing a static image

            I am not sure if this is the best library for QR code scanning. My aim is to implement a button that triggers the camera, scans QR,enter image description here and puts the scanned string into the input field.

            Try with ngAfterViewInit(). It is called after the view is initially rendered. This is why @ViewChild() depends on it.
