Typescript doesn't seem to be working on OSX 10.12.6, Atom 1.21.0

I've been using YouCompleteMe on vim for years. This is probably an easy fix but I had zero luck finding anything relevant on Google and I'm asking on here as a last resort, so thanks in advance for any help!

I'm using the same ycmd install I use for vim and testing on the same file in atom and vim, called menuview.ts. Relevant part:

export class MenuView {

  items: Array<any>;
  editorView: EditorView;
  dom: Element;

  constructor(items:Array<any>, editorView:EditorView) {
    this.items = items
...

In vim, if I run :YcmdCompleter GetType on this.items, I get back (property) MenuItems.items: any[]. Awesome.

I have my you-complete-me packages settings pointing at the same python and folder that vim uses. In Enabled Filetypes I have c, cpp, objc, objcpp, js, py, ts (I've also tried typescript here). I see YouCompleteMe working, but when I try to GetType on the same line I get this error:

No semantic completer exists for filetypes: ['ts']

    current_filetypes ) )

At the moment I'm befuddled. Thanks again for any help!

The name of file types can be different between ycmd and atom. So there is a function used for converting, for example, js and jsx to javascript. It is likely that ts has a different name in ycmd. You can try modifying that function and see if it works. Also sending a PR is welcome.
