Importing const from barrel = undefined

[montella1507]

//index.ts
import * as components from './components';

export const COMPONENTS = [
components.WidgetComponent
];

// module.ts
import { COMPONENTS } from './index';
@NgModule({
declarations: [
...COMPONENTS
],

= components are undefined.

Hi @montella1507, thanks for your report, but this doesn't tell much. A repo with the issue would be helpful.

Hello,

ok i will try to simulate it in your example app.

[montella1507]

@thymikee i have resolved my issue, yet i dont know why it occurs..

my project structure:
/src
app.module.ts
/shared
/models
/app
index.ts

That index.ts was reexported:
export * from './app';
it works for every build - ng build, ngc build, aot build.. but with JEST..

it takes "from './app'" as app.module.ts file.. So it is error...

Try the latest version of the preset

[montella1507]

Current:
jest-preset-angular@^2.0.5

i would try and i will let you know.

4.0.0-beta.1 works. Thank you :-))

Uff. i have spent 6 hours on everything :-) Reworked imports, tried to get rid of several barrels... Madge tool, ng tool for circullar dependencies :D unfortunately i just had to wait for the new version of preset :-)

The fix for issues like this was a part of v3, which was released some time ago. Glad it worked for you :)
