If you do not have special needs I think GWT-RPC is still fine especially with a jakarta version now available. But while it is easy to use it also has some annoying downsides you have to live with.
However there are quite some options: - JsInterop based DTOs + JSON.parse/stringify. However you loose inheritance or have to write some helper code to workaround it as needed - Use a json based library that solves the polymorphism problem for you - Use gRPC for the web (grpc-web) which requires a proxy in front of your server gRPC endpoint to transparently convert binary to json - Use websocket in either plain text mode or binary mode. If in binary mode you could use protobuf or similar to build the payload Personally I always wanted to explore using nats.io, which is a message broker that also supports a request-reply pattern out of the box. That means a message channel/topic acts like a service. Nats has a nats-websocket library which connects browsers to the message broker and you can use protobuf or similar to define/generate your binary messages. Because you now have a message broker between clients and servers it should be relatively easy to scale and you get things like broadcast a message to all clients (push) with little effort. Nats also has a distributed KV store integrated if needed. -- J. Christian Hebert schrieb am Mittwoch, 10.
