Is is possible to get a signalr-client.d.ts file

I can get the .d.ts files for all the components/parts of the signalr client

but I would like to be able to write the typescript file that produces the js for my page where I use signalr

when I try to reference the signalr-client.js into the .ts file I have mixed results and have only kind of made it work, but not really only partly. It looks like the signar-client-js is setup to produce module/exports which I have read about on the typescript site

I am a typescript novice, so I might be just doing it wrong?
Or is it possible to get a signalr-client.d.ts produced like the rest of the components of the client can be?
