Newman, A Functional REST Client for Scala

  • Feb 10, 2014 · 6:30 PM

StackMob (recently acquired by PayPal) operates a large distributed system composed of multiple services to provide fast, useful and highly available features for our users. We use HTTP and JSON for our wire transport and serialization protocol to communicate between services, and we use Newman to make all those calls.

Our services are built almost exclusively in Scala, so we built Newman as a Scala library that builds an abstraction layer on top of various HTTP client libraries. It has a simple DSL for making requests, handling responses and doing JSON serialization/deserialization. Newman ensures that our RPC calls are fast, asynchronous, and most importantly standard across our whole stack.

Aaron Schlesinger is a Sr. Member of the Technical Staff at PayPal where he is a member of the User Domain Platform team that builds services to store, process and serve the user profile data for PayPal's 140M+ users.

    Thanks everyone for coming to this talk.

    I've added the slides to, with one modification:

    I changed the slide that came after "Make the common case fast and the hard case possible." because it pointed to the wrong filename.

    It was a pleasure meeting everyone.
