Course details

Are you looking for alternatives to REST APIs to improve internal communication between services? In this course, instructor Martine Moses shows you how to create fast APIs using the Google Protocol Buffer (protobuf) and Google Remote Procedure Call (gRPC), two of the most consistent, easy-to-use, open-source options for connecting and managing services across multiple platforms.

Explore the basics of protocol buffers and gRPCs, when to use which, how to define a protobuf, how to set up a gRPC, and more. Boost your career with in-demand skills that you can apply on your next job search, testing out your new technical know-how in the exercise challenges at the end of each section. Upon completing this course, you’ll be ready to start defining protobuf messages and services, as well as creating gRPC servers and clients in both Go and TypeScript.
