There is a strong case for transpiling if you have a node backend. Presently we use ES2015 features on the backend that wont work in the front-end code without a transpiler. It&#x27;s not really inconvenient, but it would be nice to use many of the ES2015 features in both places. Shared libraries in particular can be built using ES2015 features instead of settling for the lowest-common-denominator. We also use make in our build tooling.
