Provide Typescript typings file

[epatpol]

I have a node backend written in Typescript and I would like to trace it using this framework (adding my own trace events and whatnot) like this however the lib doesn't come with a typings file.

Also is it possible to generate a backend trace (using node) and view it in the same viewer as the frontend trace (so that we can see backend/frontend communications/delays and whatnot).
