Source maps are broken

[wilson353]

Source maps reference files that are not present. This leads to warnings during a production build with vendor sourceMaps enabled.

ng build --prod

"sourceMap": {
  "hidden": true,
  "scripts": true,
  "styles": true,
  "vendor": true
}

WARNING in ./node_modules/ngx-cacheable/esm2015/common/DOMStorageStrategy.js
Module Warning (from ./node_modules/source-map-loader/index.js):
(Emitted value instead of an instance of Error) Cannot find source file '../../../common/DOMStorageStrategy.ts': Error: Can't resolve '../../../common/DOMStorageStrategy.ts' in '.../node_modules/ngx-cacheable/esm2015/common'

Thoughts on disabling sourceMaps for dist?

I need to investigate this.. Will get back to you when I find time to do that. Also, if you can make a PR I can review, that'd be even better. :)

Same problem here, using version 1.4.1. Get the warnings during build and during 'ng serve'. Output from serve:

To me it seems like the path it searches for the files is wrong. The "../../../" takes it back to the node_modules folder, where there is no 'common' folder. Inside node_modules/ngx-cacheable/esm2015/common folder the files exist, but with "d.ts" extension, instead of ".ts".

[angelnikolov]

Hm, can you show me your angular.json config for serve? I can't reproduce that during serve. Also I assume you are using DomStorageStrategy right?

[angelnikolov]

@TacticalVilius Okay, I think I managed to find the issue. I was not publishing the source code, which in case of vendor source map building is required. Can you please try it out with the version below and let me know if it works. Then I will release it @ latest. cc @wilson353 http://npmjs.com/package/ngx-cacheable/v/1.4.2-beta.1

[TacticalVilius]

@angelnikolov , it works, the warnings are gone. Thanks for the quick fix!

[angelnikolov]

Right, will publish version in latest later. Thanks!

[angelnikolov]

1.4.2 is now published. Thanks again!
