Set up karma for typescript branch #10

Closed thepassle closed 6 years ago

thepassle commented 6 years ago

I've implemented a typescript branch, that I want to set up Karma for. Due to lack of experience with karma/typescript, I could use a hand. I'm using a basic setup from karma-typescript

Currently this results in:

19 10 2018 15:16:16.863:INFO [compiler.karma-typescript]: Compiling project using Typescript 3.1.3

If anyone is more experienced with typescript and karma, i'd love to have a helping hand :)

I'll be diving into this more this weekend.

And the solution or reason for closing was?

Fixed it, and tests run in the typescript branch: https://github.com/thepassle/create-lit-app/tree/typescript
