An idea very similar to what we have developed some years ago. A much older version of it is still publicly available however not maintained (moved to private repo, more on this in a second):
<a href="https://github.com/intelix/reactiveservices" rel="nofollow">https://github.com/intelix/reactiveservices</a>
some runnable examples are here: <a href="https://github.com/intelix/reactiveservices-examples" rel="nofollow">https://github.com/intelix/reactiveservices-examples</a><p>And the screenshot is the early version of the real app built on it<p>Conceptually it's the same to what described in conductor, however you are in full control how the data is synced, how and to what you subscribe etc.<p>It was built, first of all, for the application in forex trading, so there are some "specific" features, such as optimised binary stream with delta-only updates, priority on the data streams, demand-based backpressure, subscription based on the visibility of the data, very low latency, cross-dc clusters and many more.<p>How it works is described (in rather over-simplified way) on the github page. There's a choice of scala or java on the back end, and react on the client side. Websocket only. Like I mentioned, the currently exposed source code is not maintained and based on the very old version of react (there are still mixins in the example) and libs, and has some vulnerabilities.<p>The latest version of the framework is maintained in the private repo, and we have built a number of solutions on it over the years, and not only in the forex space. It is well suited for most Single-page apps.<p>Latest version uses latest react features, hooks based, and the server side has seen significant changes as well.<p>Why we decided to keep it private? We thought world already have enough web frameworks, and since, we thought, our framework and approach was such a niche, we just kept using it for our clients and our own projects. But since then we have been surprised how easily it could be applied to other fields, and yet there's still nothing like this is available. GraphQL with subscriptions probably is the closes, but not good enough.<p>Is there any interest in something like this in the community? If so, we can definitely make large parts of the framework, which is now 6yo, public.
