App.js

(function() {
  var angular_websocket;

  angular_websocket = require('angular-websocket');

}).call(this);

Command browserify app.js -o bundle.js gives:

Fixed with npm install bufferutil utf-8-validate, and I suspect this issue is probably not within the scope of angular-websockets to fix. Should these actually be dependencies of ws or does it make sense for these to be dependencies of this project directly?

[Remco75]

nope, I think this is somewhere within this module: webpack doesnt work as well.
some code has changed so it tries to load to much it seems :-(

[chaddjohnson]

I vote for bufferutil and utf-8-validate being added as dependencies of angular-websocket. Is there a reason the author didn't do this?

[Ocramius]

This was handled in fdfea1f

[odedniv]

Don't you need this in production? (was added to devDependencies)

[danielpiedra]

any insights here? i believe @odedniv is right..

[krobing]

I've not needed to install those dependencies, because anyway when I running the node.js server, it throw an error in socket.io, so what I've done is exclude those dependencies bufferutil and utf-8-validate when run browserify on the terminal or as statement so this way -u bufferutil -u utf-8-validate.

I'm facing similar problem (with webpack):

Drive by comment, I came across this same error when including ws in the client side. It's actually not needed on the client side and browsers should use the native WebSocket constructor. See this issue for more information: websockets/ws#423

If your client is in browser you can use my fork to resolve this issue.
npm i jacek-jaskolski/angular-websocket --save

This seems to have been deleted. I needed it for an old project. In case anyone is here looking for it, I have it up at 'Araevin/angular-websocket'.
