Envoy and gRPC-Web: A Fresh New Alternative to REST

51

gRPC-Web is a JavaScript client library that enables web applications to interact with backend gRPC services using Envoy instead of a custom HTTP server as an intermediary. Last week, the gRPC team announced the GA release of gRPC-Web on the CNCF blog after nearly two years of active development.

Personally, I’d been intrigued by gRPC-Web since I first read about it in a blog post on the Improbable engineering blog. I’ve always loved gRPC’s performance, scalability, and IDL-driven approach to service interaction and have longed for a way to eliminate REST from the service path if possible. I’m excited that gRPC-Web is ready for prime time because I think it opens up some extremely promising horizons in web development.

The beauty of gRPC-Web, in my view, is that it enables you to create full end-to-end gRPC service architectures, from the web client all the way down.
