doesn't work with ng build or ng build --prod about angularx-qrcode

[Cordobo]

Hi @bkimminich , I'm actively working on a version without this error, meanwhile a temporary workaround has to be applied, es2015 as target does not work yet for production builds, see here:

https://github.com/Cordobo/angularx-qrcode#install-160-with-angular-8

You could although checkout the sample repo from above, which doesn't throw the this._android error with angular 8.

Hi @frabanca,

Please use the workaround mentioned above until a refactored version is available:

Replace:
"target": "es2015"
with
"target": "es5"

Closing this, as I'm actively working on this.

Hi @harkal18 , glad you like the lib. I'm working on the fix for Angular 8+.

Did you try this temporary workaround? Set the target in your tsconfig.json from es2015 to es5:

"target": "es5"

I created a sample repo for Angular 8 here: https://github.com/Cordobo/angularx-qrcode-sample-app

The only difference I see is "module": "es2015",, whereas my tsconfig.json states "module": "esnext", (although both worked in my test)

The following is just to be sure we both have the same setup:

1. Checkout the sample-repo
2. Run npm install(or remove all npm modules and reinstall)
3. Run ng build again
4. Run npm run dev to start up a local server for your production-build

I am using ^1.6.0 which compiles with both es5 and es2015 without problems. But when loading the application with es2015-compiled code I get this error:

[harkal18]

thats ok
but why does it work in localhost then ?

[harkal18]

it still doesn't work bro
i haven't changed anything in my project and just now i looked at my tsconfig.json
this is how it looks
{ "compileOnSave": false, "compilerOptions": { "baseUrl": "./", "outDir": "./dist/out-tsc", "sourceMap": true, "declaration": false, "module": "es2015", "moduleResolution": "node", "emitDecoratorMetadata": true, "experimentalDecorators": true, "importHelpers": true, "target": "es5", "typeRoots": [ "node_modules/@types" ], "lib": [ "es2018", "dom" ] } }

it looks adjactly how you want it
target set to es5

Hi @Cordobo, I have been waiting for this path since long time now. Can you please help us with the fix. By the way Angular 9 is on the edges to get released so probably you should also patch for the angular 9.

Hi @anantanandgupta

Unfortunately, there is no easy patch to apply, please follow issue #53
