@tusharmath Hi there.

You can actually use typescript 2 with this project.

Firstly, include typescript2 in your package.json:

npm install --save-dev typescript

Secondly, override the typescript version by editing your rollup.config.js:

typescript({
  typescript: require('some-fork-of-typescript')
})

That should be enought. It works for me.

I think the better approach is to remove typescript from the dependency list, and let the user decide which version of typescript to use.
