QUESTION
I referring https://www.npmjs.com/package/cordova-plugin-qrscanner and trying to create a QR Scan function in my mobile app.
So for first steps, I am creating the following code in my ts file:
...ANSWER
Answered 2022-Feb-17 at 06:10Good 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.
QUESTION
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:
...ANSWER
Answered 2021-Aug-15 at 13:53That 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.
QUESTION
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.

QUESTION
Hi I have developed an app using Cordova and mainly developed it by testing IOS first. I have now published the app on the App Store and now want to publish it onto the google play store.
I have been testing the app via android studio and can't get past my login page. When I fill the form and submit it no AJAX request is made to check my login credentials and log me in.
I am using the android studio profiler to check if a request is made and I can't see one. I have added logging before the Ajax request but after the form is submitted and that is working.
After looking through multiple forums I still can't seem to get it working. I have added the white list plugin, I have setup CORS correctly because I had to do this to get it working for IOS.
Here is my config.xml file
