Web RPC, Datastreams & Data Channels With JS Client

[sirinath]

Can we have JS Client which can be on the browser which can communicate with the server using a higher abstraction like RPC, Datastreams and/or Data Channels?

This can perhaps just providing a JS implementation of:

• RPC
• CSP
• Datastreams
• Dataflow
• Serialisation
• Codec

JS implementation will be to use it from the web.

JS side can also have DI implementation.

Hello, @sirinath
We currently have no plans of porting our components to JS.
Some components are tightly coupled with JVM and it would not be possible to port them.
While other components theoretically can be ported to JS, they would probably lack a performance provided by JVM.
As for Dataflow and RPC clients, they use TCP for exchanging messaging with servers. And unfortunately, you cannot exchange raw TCP messages directly from the browser right now. You would need some kind of proxy for that.

I guess the problem is client-server communication which is very limited. I guess this can be rectified by implementing some of the standards on the server side like:

• WebSockets
• Server Sent Events (SSE)
• CometD, Bayeux Protocol, Long Polling, JSONRequest, Bidirectional-streams Over Synchronous HTTP (BOSH)
• WebRTC
• REST
• GraphQL
• gRPC, MsgPacket, Fast Binary Encoding (FBE), Concise Binary Object Representation (CBOR), Simple Binary Encoding (SBE), FlatBuffers
• WebDAV
• XMPP
• etc.

This way existing JS libraries can be used on the client-side/frontend-side.

Most important would be along with Ajax are:

• WebSockets
• Server Sent Events (SSE)
