Getting errors right can be tricky and it can be even trickier in gRPC. The current version of gRPC only has limited built-in error handling based on simple status codes and metadata. In this article, we will see what are limitations of gRPC error handling and how to overcome that
An API Gateway or Backend for frontend (BFF) is an important design pattern for building applications based on microservices architecture. This reduces chattiness between clients and services by aggregating multiple requests into a single request. We can build specialized BFF services(s) to handle different interfaces for browser and mobile applications. The API Gateway can also be used to offload cross-cutting concerns such as authentication, authorization, rate limiting to a proxy.
