Where is the socket.io client library?

问题:

As far as I have seen, there is no explanation as to where we are to locate the client side script for socket.io if node.js is not used as the web server. I've found a whole directory of client side files, but I need them in a combined version (like it's served when using node.js webs servers). Any ideas?

回答1:

socket.io.js is what you're going to put into your client-side html. Something like:

<script type="text/javascript" src="socket.io.js"></script>

my script is located:

/usr/local/lib/node_modules/socket.io/node_modules/socket.io-client/dist/socket.io.js

copy that file to where you want your server to serve it.

The best way I have found to do this is to use bower.

bower install socket.io-client --save

and include the following in your app's HTML:

<script src="/bower_components/socket.io-client/socket.io.js"></script>

That way you can treat the socket.io part of your client the same way you treat any other managed package.

I think that better and proper way is to load it from this url

src="/socket.io/socket.io.js" 

on the domain where socket.io runs. What is positive on this solution is that if you update your socket.io npm module, your client file gets updated too and you don't have to copy it every time manually.

I used bower as suggested in Matt Way's answer, and that worked great, but then the library itself didn't have its own bower.json file.

This meant that the bower-main-files Gulp plugin that I'm using to find my dependencies' JS files did not pull in socket.io, and I was getting an error on page load. Adding an override to my project's bower.json worked around the issue.

First install the library with bower:

bower install socket.io-client --save

Then add the override to your project's bower.json:

"overrides": {
  "socket.io-client": {
    "main": ["socket.io.js"]
  }
}

For everyone who runs wiredep and gets the "socket.io-client was not injected in your file." error:

Modify your wiredep task like this:

wiredep: {
  ..
  main: {
    ..
    overrides: {
      'socket.io-client': {
        main: 'socket.io.js'
      }
    }
  }

回答6:

If you are using bower.json, add the socket.io-client dependency.

"socket.io-client": "0.9.x"

Then run bower install to download socket.io-client.

Then add the script tag in your HTML.

<script src="bower_components/socket.io-client/dist/socket.io.min.js"></script>

I have created a bower compatible socket.io-client that can be install like this :

bower install sio-client --save

or for development usage :

bower install sio-client --save-dev

link to repo

if you use https://github.com/btford/angular-socket-io make sure to have your index.html like this:

<!-- https://raw.githubusercontent.com/socketio/socket.io-client/master/socket.io.js -->
<script src="socket.io.js"></script>

<!-- build:js({client,node_modules}) app/vendor.js -->
<!-- bower:js -->
<script src="bower_components/jquery/dist/jquery.js"></script>
<script src="bower_components/angular/angular.js"></script>
<!-- ...... -->
<script src="bower_components/angular-socket-io/socket.js"></script>
<!-- endbower -->
<!-- endbuild -->



<script type="text/javascript" charset="utf-8">
   angular.module('myapp', [
// ...    
'btford.socket-io'
]);

// do your angular/socket stuff
</script>
