Steps to reproduce

yarn run build

What is expected?

Should produce a d.ts file to import the component

What is actually happening?

Generates a MLiveForce.common.js but nothing TS specific.
The problem is that without a .d.ts file the component can't be imported. WebStorm says "Cannot find module xxx"
