Are frameworks getting an Encore?
Tools and frameworks that aim to boost developer productivity are always worth a closer look, but we don’t often consider the trade-offs for whichever we settle on. In this episode, we discuss the questions one should be asking when evaluating developer productivity tools and frameworks in the Go ecosystem in particular.
Joining us to discuss is André Eriksson, the creator of Encore, a backend framework that aims to make development and deployment as productive as it can be.
