The post explores the practical implementation of gRPC servers and clients over HTTP/3 using Go's ConnectRPC and quic-go libraries. HTTP/3 leverages QUIC, a protocol built on UDP, to reduce latency and improve performance. Despite the early adoption phase, the potential for enhanced performance and security in API development is evident. Practical examples and experimentation reveal current capabilities and limitations of gRPC over HTTP/3. ## Full article daily.dev links to this article rather than hosting it.
