I do not see many changes except for stylistic ones (which do not count).

Please check that it is working, eventually fix the comments you mentioned and you can merge this.

@seyfeb Does it make sense to backport this to the main-0.10.x branch?

[seyfeb]

Probably yes. I guess much of new frontend code could/should use typescript while existing code may be refactored into typescript. So if we want to continue to backport things the 0.10.x branch should have ts support, too.
