@lihsai0 Thanks!

Have you used it yet? I'm not sure if it really fixes the linked issue or not.

@XhmikosR I use it by 'npm link' in my local environment and it works fine. In my case, it is react component not angular component. But I think that isn't related. This should work with all TypeScript projects.
