Clarifai's transition from Django to a setup utilizing grpc-gateway has facilitated the development of an API framework that supports both gRPC and RESTful styles, enabling HTTP/1.1 requests with JSON bodies to be routed to gRPC handlers with protobuf bodies. This integration allows for the definition of APIs with gRPC methods, subsequently transforming them into RESTful APIs while maintaining the ability to handle both gRPC and HTTP requests on the same server. The implementation of grpc-gateway has led to the creation of a scalable server infrastructure running for over two years, supporting over 140 API endpoints, with enhanced capabilities such as automatic client generation, authorization scopes, and swagger file generation. The system's core is built around protocol buffers, providing an extensible, object-oriented structure that simplifies API management and expansion.
