## 📝 Getting Started

```
git clone https://github.com/aaron5670/ExpressJS-SocketIO-Boilerplate.git

cd expressjs-socketio-boilerplate

npm install

// Optional: if you want dummy data, then run this seed file
node seed.js

node server.js
```

## ⚡ Create Socket.io connection
Install on your client-side (web) application the module [socket.io-client](https://www.npmjs.com/package/socket.io-client).
```
npm install socket.io-client
```

Then create a connection with the following code:
```javascript
// with ES6 import
import io from 'socket.io-client';

const socket = io('http://localhost:3005');
```

For more info you can read the official Socket.io documentation:
- [Official docs](https://socket.io/docs/)
- [Server API](https://socket.io/docs/server-api/)
- [Client API](https://socket.io/docs/client-api/)

## 📓 How to document the Swagger UI endpoint API
```javascript
/**
* @typedef ResponseJSON
* @property {string} username - user's username - eg: janet
* @property {string} message - message - eg: This is a authenticated route!
*/
/**
* Dashboard endpoint only allowed for authenticated users
* @route GET /api/v1/auth/dashboard
* @group Auth
* @returns {ResponseJSON.model} 200
* @produces application/json
*/
router.get('/dashboard', authenticationMiddleware(), (req, res) => {
return res.json({
username: req.session.passport.user.username,
message: 'This is a authenticated route!'
});
});
```
If you are running this boilerplate on you localhost you can see the Swagger UI documentation on: http://localhost:3005/api-docs/.

**Note:** *Check if your port number is the same as your [configuration](https://github.com/aaron5670/ExpressJS-SocketIO-Boilerplate/blob/master/config.js)*.
