[Q] Is it possible to Lightroom can connect WebSocket server on localhost?

[Naoki-Hada]

Hi all,

I have current running WebSocket server on localhost.

I'd like to make Lightroom plugin that connect the server.

My understanding is following.

     * Lightroom modules cannot add third party code like LuaRocks installation.

     * Lightroom 6/CC has LrSocket and LrHttp.

Is that possible to implement WebSocket client on top or LrSocket or any other way?

Thank you,

Naoki

     * Lightroom modules cannot add third party code like LuaRocks installation.

You can include third-party source as long as you convert it to Lua 5.1 (if necessary) and the restricted Lua environment provided by LR (see the Lightroom SDK Guide for the restrictions).

     * Lightroom 6/CC has LrSocket and LrHttp.

Is that possible to implement WebSocket client on top or LrSocket

My brief skimming of WebSocket is that it is a bidirectional, non-HTTP protocol (that starts with an HTTP handshake).  Unfortunately, each instance of LrSocket is one-way (send or receive).  So I don't see how it could be used to implement WebSocket.

johnrellis, thank you very much for your input. I think similar way but still look for solutions.
