Intro to gRPC: The REST alternative
gRPC is a binary protocol for remote procedure calls, open sourced by Google. It is an alternative to REST that has gained traction for its performance and simplicity. gRPC gives you a full duplex connection over HTTP/2. At the moment, it requires an adapter when used in the browser, and it remains most popular in back-end services. gRPC is especially popular for microservices, where its strong API contracts and method abstraction help tame complexity. Although gRPC demands more upfront work than a typical REST stack, it can be appealing for larger projects and organizations that benefit from a more structured approach.
