1.x outputs this error on npm install:

UNMET PEER DEPENDENCY continuation-local-storage@~3

The issue is reported here and supposedly fixed in 2.x.

Thanks! We have no dependency on continuation-local-storage so the change should be pretty straight forward. Thanks! :+1:

Yep - opened #80 to run tests - having some problems getting docker up and running to test locally.

Resolved via #80
