[chuck-users] web integration

[Jack Atherton]

Hi Michael,

You can deploy a page in a way that loads a bunch of files into the file
system and runs them when the VM is initialized. See preloadfiles.js and
theChuckReady.then() (in host.js) below. One problem you might hit -- if I
remember correctly, creating subdirectories in the ChucK virtual file
system is broken. So, all your virtualFilenames will likely need to be at
the top level of the directory.

https://ccrma.stanford.edu/~lja/timbre-library/js/preloadfiles.js
https://ccrma.stanford.edu/~lja/timbre-library/js/host.js

(For an example of the directory shenanigans:)
    {
        serverFilename: './chuck/voicebank/intqueue.ck',   // hierarchy ok
on your webserver
        virtualFilename: 'intqueue.ck'                                  //
hierarchy not ok in the virtual file system
    },
