Escher looks really interesting, and a really good match to a hypothetical project I'm planning. So does Julia --- I've done a little scientific computing, mostly in C++, but I'm mostly interested in general-purpose programming, and a quick glance over Julia's feature set makes it look really promising. (Although I'd still like a static type checker.)

If all the logic happens server-side in Escher, what's the responsiveness like? Do you have a live example anywhere?

Are there any plans to transpile Julia into Javascript?

Responsiveness is excellent when your Julia process is on the same machine as the browser - which in itself addresses a large set of use cases scientific computing audience has (such as presentations). When the Julia process is connected over the network, there is obviously a lag between updates. But it's no better or worse than an AJAX/WebSocket application. The intention is to use web components to encapsulate UI components and their behavior (including self-contained animations) and Julia to read from them and update their attributes. So one can switch to writing web components and using them in Escher if responsiveness is really a concern. With the programming model in Escher, it will be easy to hoist some computations to the browser once there is Julia to JavaScript compilation. However, I don't plan to write the transpiler (yet) ;).

So Web Components become the C of the MVC triad, with invisible RPC over the network to Escher for the MV running in Julia? I really like that idea, particularly if the RPC protocol falls back gracefully from WebSocket to long-polling to polling.

Do you know of anything using Escher for public web-facing applications yet?

Since Julia uses LLVM IR, it should be possible to go from LLVM to Javascript using emscripten.
