I'm building a Pyramid application, but I would like to have a light-weight REST API built in to it. I've built such an API already with Flask, so is it possible to build my application in both Flask and Pyramid simultaneously?
Is it possible? Yes. It is however very inadvisable and tricky to do so. You can build a light-weight API fairly quickly using Cornice which is Pyramids answer to RESTful frameworks. Hope this helps!
