Can you use RPC with JavaScript?

Absolutely, you can use RPC in JavaScript! gRPC, JSON-RPC, and tRPC are all options. The choice really depends on your specific needs, especially if you're focusing on microservices or API communication.

Yes, gRPC is supported in several languages, including JavaScript. You can implement it on a Node.js server or in the browser. If you're making requests from the browser, you might want to use a proxy like Envoy to handle the gRPC calls.

We actually use ConnectRPC combined with buf.build for managing schemas in our development process. ConnectRPC works well with both gRPC over HTTP/2 and its JSON format over HTTP/1.1, which can be helpful for various implementations.
