I have Typescript package A where I create

export abstract class Network extends pulumi.ComponentResource

. In package B, depending on A, I create a concrete subclass

class GoogleNetwork extends network.Network

. In the same file where this concrete class is defined, I use it via

this.virtualNetwork = new GoogleNetwork(name)

. The build works, but when running tests, I get this error:

TypeError: Class constructor Network cannot be invoked without 'new'
    at new GoogleNetwork (/Users/ringods/Projects/cumundi/blueprints/libraries/packages/network-gcp/src/index.ts:21:23)
    at GoogleNetworkBuilder.network (/Users/ringods/Projects/cumundi/blueprints/libraries/packages/network-gcp/src/index.ts:29:31)
    at Object.<anonymous> (/Users/ringods/Projects/cumundi/blueprints/libraries/packages/network-gcp/test/simple.ts:5:6)
    ...

This is probably something missing in my

tsconfig.json

files, but I failed to find what so far. I experimented with the following

compilerOptions

so far:

target

,

module

,

moduleResolution
