```js
var Pusudb = require('pusudb')
var pusudb = new Pusudb(3000, 'localhost', { log : true })

var AuthJwt = require('pusudb-use-auth-jwt')

/**
 * Default options {
     *  login: '/login',
     *  logout: '/logout',
     *  signin: '/signin',
     *  signinActive: true,
     *  redirect: '/index',
     *  redirectActive: false,
     *  cookie : 'bearer', // cookie key
     *  cookieOptions : { maxAge : 365 * 86400 } // see npm cookies for other options
     *  secret : 'my-token-secret', // default a unique-string
     *  db: './users', // define './other-db' or __dirname + '/pathToDb/users'
     *  form: { password : 'password', name : 'email' },
     *  expire: '1y', // json webtoken expires in
     *  assignUser: false // assign key and userName to req.docs to handle it in the response
 * }
 */

var authjwt = new AuthJwt(/* options */) 

// Add some routes which needs authentication ( string || array )
auth.setRoutes('/admin', '/mypanel')
auth.setRoutes('/private', ['/privateOne', '/privateTwo'])

auth.setRoutesWebSocket('/api')

//add the middleware to the pusudb
pusudb.useBefore('http', authjwt.serve)

//add the middleware to the pusudb for websocket-authentication
pusudb.useBefore('ws', authjwt.serveWebSocket)

pusudb.listen(function(port, host){
    console.log('pusudb listening:', port, host)
})

// Logout
ws.send(JSON.stringify({ meta : 'logout', data: { value : { email : 'pusu@pusu.com', password: '1234'}}}));
