Aurelia-Slickgrid and Slickgrid-Universal
Whenever you want to update your Aurelia-Slickgrid, you should also always update all your Slickgrid-Universal packages (if any) at the same time as your Aurelia-Slickgrid and it should be all good. If you have problem with older versions, take a look at the list of compatible versions below.
Why do Aurelia-Slickgrid and Slickgrid-Universal versions have to go hand in hand?
I believe the biggest reason is because Aurelia-Slickgrid extends (GridOption) interface from Slickgrid-Universal and TypeScript seems to be detecting invalid types and throwing a bunch of errors when they're not updated the same day, I never figured out why or how to fix this problem (if you know please provide a PR).
