Re: EPICS Channel Access (PV access) to REST bridge?

[Rees Simon via Tech-talk <tech-talk at aps.anl.gov>]

Dear Vincent

At PSI we have developed WICA "Web Interface for
Controls Applications", which provides:

- a backend service for streaming the state of
   EPICS channels over an http (REST) interface.
   It also supports basic get and put functionality.

- a frontend JS library that can interpret the
   event stream to update the html elements on a
   user's webpage in realtime.

The above is as far as it takes you; it's then
down to the user to develop the webpages that
leverage off this functionality according to
your needs and preferred technology choices.

The Wica backend service runs either as a fatjar
you can start on the command line, or as a service
you can run in a docker container.

WICA is an open-source project available on
GitHub here:

Unfortuantely, currently there is no support for
PV Access.

Limited resources our end means we have had to
focus our development efforts elsewhere in recent
years, but it may give you some ideas.
