Update the chat example

[darrachequesne]

• make the example autonomous (npm install && npm start)
• add disconnect/reconnect logs (and send username on reconnection)

Why make it autonomous? Is it to make compilation easier for beginner devs or some other reason?

Deffo a 👍 for the extra events though 😄

[darrachequesne]

@MaffooBristol yes, it feels easier to run it as a standalone (to me). It may be a bit superfluous though.

[MaffooBristol]

Hmm, maybe. But then is it not better for the examples to be entirely tied to the current source version rather than npm's version? Also it means that anyone editing the source can see whether it breaks the chat example, as a form of testing? Just not sure if I think it's the best idea personally.

maybe in package.json
It's better to change start command to node index.js to specify file name.
The remaining parts are good!!!

I'm getting a 'cannot find module ../..' when trying to follow this example.

[darrachequesne]

@KevinHoughton the require('../..') here is a reference to the root repository, hence the installation steps:

$ cd socket.io
$ npm install
$ cd examples/chat
$ npm install
$ npm start

You can also replace it by require('socket.io'); (and npm i socket.io, of course).
