## How to use
A standalone build of `socket.io-client` is exposed automatically by the
socket.io server as `/socket.io/socket.io.js`. Alternatively you can
serve the file `socket.io.js` found in the `dist` folder or include it via [CDN](https://cdn.jsdelivr.net/npm/socket.io-client@2/dist/socket.io.js).
```html
<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io();
socket.on('connect', function(){});
socket.on('event', function(data){});
socket.on('disconnect', function(){});
</script>
```
```js
// with ES6 import
import io from 'socket.io-client';
const socket = io();
```
A slim build (without `JSON3`, a JSON polyfill for IE6/IE7, and `debug`) is also available: `socket.io.slim.js`.
Socket.IO is compatible with [browserify](http://browserify.org/) and [webpack](https://webpack.js.org/) (see example [there](https://github.com/socketio/socket.io/tree/2.0.3/examples/webpack-build)).
### Node.JS (server-side usage)
Add `socket.io-client` to your `package.json` and then:
```js
var socket = require('socket.io-client')('http://localhost:3000');
socket.on('connect', function(){});
socket.on('event', function(data){});
socket.on('disconnect', function(){});
```
## Debug / logging
In order to see all the client debug output, run the following command on the browser console including the desired scope and reload your app page:
```
localStorage.debug = '*';
```
And then, filter by the scopes you're interested in. See also: https://socket.io/docs/logging-and-debugging/
