Migrate the codebase to typescript from ES6.
Use the latest TS and tslint.

Hello, could I be reassigned to this issue, I'd like to help you with the migration if it is still relevant.

Hi,
no problem at all. It would be great to finally migrate this project to the latest version of Typescript.
Be sure to check updates of other dependencies, to keep compatibility between used libraries.
