Re my last mail,
I meant to say using the proton.js is fine BTW, the makefile actually
builds it into
fadams-javascript-binding/bld/proton-c/bindings/javascript which is what
you'd normally get with CMake but then copies it to the node_modules
directory 'cause that's generally more useful. For a real browser based
application you'd generally take that file and serve it from your Web
App, but as it's WebSocket based you don't actually need to serve it to
be able to use it, you can run from the filesystem as you've discovered.
I also forgot to say that I don't really understand the bit:
"
When I browserify the proton.js into qpid-proton-browser.js and load that file
instead, I get the following when the page loads:
Uncaught TypeError: Cannot read property 'replace' of undefined
proton is undefined
Uncaught ReferenceError: proton is not defined
The Uncaught TypeError is due to a referece to "process.argv[1]". If I manually edit the
qpid-proton-browser.js file to define all the process properties that it wants, I still get the
"proton is undefined" error.
"
What do you mean by "When I browserify the proton.js into
qpid-proton-browser.js "? I just copied proton.js to qpid-proton-browser.js
in fadams-javascript-binding/node_modules/qpid-proton/lib
and changed the script tag in the HTML to point to that and it still
works for me and it gives the same error as proton.js when I remove the
"tracker =" bit in front of messenger.put(message)
So I'm not really sure what you did that gave you the different error.
as I say using the proton.js is fine, but I'm curious as to what you
actually did?

Hi Fraser,
I'm trying to run the proton javascript bindings from within a browser. I'm
getting various errors depending on the way I'm doing it and I was hoping you
could shed some light on the correct approach.
I have node recv.js running in a separate window.
The first way I tried was just including proton.js directly. When I load the
page the console shows the following for the HTML listed below:
pre-main prep time: 6 ms
proton is [object Object]
before put
Uncaught TypeError: Cannot read property 'fa' of null
Uncaught TypeError: Cannot read property 'fa' of null
Here is the HTML:

The output in the window running node recv.js is:

Do you know what I'm doing wrong?
