tslib outdated preventing the use of spread syntax?

[stephencweiss]

I'm trying to use a spread operator on an array in my TSDX library and am getting the following error:

The error in full:

This syntax requires an imported helper named '__spreadArray' with 3 parameters, which is not compatible with the one in 'tslib'. Consider upgrading your version of 'tslib'.

For the most part it's impossible to tell that there's a problem - in fact, there is no problem when I run this application in the test app that comes with TSDX. However, when I consume the library, this function appears to fail in interesting ways (basically, I just get a blank object instead of any actual data - so no "failure", just not what i'd expect).

I'm not particularly familiar with tslib, but tsdx has the oldest version dependency on tslib in my dependency graph. It's at 1.9.x and this function was installed at 1.10.x (source)

A few questions:

1. I tried simply changing my target (source) - this didn't work. Should it have?
2. Is it possible to update the dependency in tsdx to 1.10+? (it's now on a 2.x release)

Any other guidance is very much appreciated!

I also found this thread and am not sure if it's relevant: #659

It says in the document to use __spreadArray instead
