desktop applications written in clojure

Question

Which technologies from the clojure ecosystem can be recommended to develop a standalone desktop application? The technology I am looking for should have support for

• access to the local file system (e.g file dialogs).
• access to the web via http/https
• support for updating the desktop application
• async support (running multiple threads)
• cross platform (no need for smartphones though)
• interop support to native libs (not 100% required, but it's a risk if it doesn't have support for it)
• reasonable ecosystem. E.g. I need to validate xml files to xsd's, eventually I need to make some linear algebra calculations.

The following alternatives come to my mind:

clojure/seesaw:

• -- requires java runtime
• -- standard swing look/feel might be a disadvantage
• ++ robust java platform
• ++ huge ecosystem
• ++ interop support is not an issue
• ++ core.async

clojurescript/html5/css:

• ++ can be used with node-webkit or appjs to deliver standalone desktop app.
• ++ flexible look/feel via css
• ++ robust platform
• -- smaller ecosystem. E.g. what about handling xml files or support for math libraries?
• -- interop support might be an issue. Can i call e.g. native libs from node-webkit?
• -- single threaded enviroment, what about async support?
• -- unclear how to update the application.

Pedestal

• ++ simplifies developing the application architecture
• -- not sure it can be deployed as node-webkit app or appjs.

Answer 1

I think clojurescript + node-webkit is a good choice:

• it supports native libs,
• clojure.core.async,
• implement a simple update on your own by simple HTTP request or socket.io,
• lighttable is a good example.

Answer 2

Electron should be a drop in replacement for NW.js (node-webkit) and offers more flexibility over when to show and hide windows.
