gRPC in Go: Streaming RPCs, Interceptors, and Metadata

Go’s gRPC implementation uses code generation to create type-safe client and server interfaces. Streaming RPCs allow sending multiple messages over a single connection, perfect for real-time updates and continuous data flows. Interceptors provide middleware-like functionality for authentication, logging, and error handling without modifying your core service logic.

How Protobuf Works—The Art of Data Encoding

Protocol Buffers is faster and smaller than JSON, but the interesting part is understanding why. This article breaks down the encoding techniques that make Protobuf efficient, backed by benchmark results and practical examples

How HTTP/2 Works and How to Enable It in Go

HTTP/2 solves head-of-line blocking at the application layer by multiplexing multiple streams over a single TCP connection. While HTTP/1.1 requires requests to be processed sequentially, HTTP/2 allows parallel processing through independent streams, each with its own ID. The Go standard library supports HTTP/2 out of the box when using HTTPS, and with some configuration, it can work over plain HTTP too

From net/rpc to gRPC in Go Applications

The net/rpc package in Go demonstrates basic RPC concepts by establishing TCP connections between clients and servers, using sequence numbers to match requests with responses, and supporting both gob (Go-specific) and JSON codecs for data serialization. While net/rpc is simpler and limited to Go services by default, gRPC offers advanced features like HTTP/2 streaming, cross-language support, and better performance
