ts-loader issue with exported types

[panManfredini]

Somehow ts-loader does not manage to find types of interfaces like effectAPI and ExtendedlitElement.
If I compile with just tsc it works.

Error:

TS2305: Module '"../../../lit-element-effector"' has no exported member 'effectAPI'.

Seems like related to the fact that ts-loader needs a declaration file .d.ts. Tried to do that but not able because of this issue.

Maybe the solution in this issue here can also help.

Solution for now: If you really need these interfaces like effectAPI and ExtendedlitElement you can do:

• Don't import the interfaces, just copy them in your code, they are defined here and here
• Or compile in two steps, first only typescript (tsc) and then webpack.
• Or use rollup with its typescript loader

Very weird thing is:

• copy src/index.ts into index.d.ts
• point typings in package.json to index.d.ts

Like this webpack+ts-loader magically compiles. Obviously tsc does not since index.d.ts is not a declaration file done like that...
