Front-enders should check this out! Johan Brandhorst reviews the history of gRPC in the browser, the state of things today, and thoughts on the future of gRPC-Web.
gRPC-Web is an excellent choice for web developers. It brings the portability, performance, and engineering of a sophisticated protocol into the browser, and marks an exciting time for frontend developers!
So far the benefits have largely only been available to mobile app and backend developers, whilst frontend developers have had to continue to rely on JSON REST interfaces as their primary means of information exchange. However, with the release of gRPC-Web, gRPC is poised to become a valuable addition in the toolbox of frontend developers.
