I am learning JWT with NodeJs. I am stuck at passing the JWT in header actually i do not know how to do this. 

**index.js file**

```
var express = require('express'),
 app = express(),
 routes = require('./routes'),
 bodyParser = require('body-parser'),
 path = require('path'),
 ejs = require('ejs'),
 jwt = require('jsonwebtoken');

app.use(bodyParser.urlencoded({ extended: false })); 
app.use(bodyParser.json());

app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');

app.post('/home',routes.loginUser);

app.get('/', function(req, res) {
  res.render('index');
});

app.get('/home',function(req, res) {
  jwt.verify(req.token, 'qwertyu6456asdfghj', function(err, data) {
    if (err) {
      res.sendStatus(403);
    } 
  });
});

 app.listen(3000,function(){
  console.log("Server running at Port 3000");
});

```

**routes/index.js file**

```
var  jwt = require('jsonwebtoken');

exports.home = function(req, res){
  res.render('home',{error: false});
};

exports.loginUser = function(req, res) {
    var uname = req.body.Username;
    var pwd = req.body.Password;

    if(uname && pwd === 'admin'){
        res.render('home');

    var token = jwt.sign({ user: uname }, 'qwertyuiopasdfghj');
    console.log('Authentication is done successfully.....');
    console.log(token);
    }

    response.json({
        authsuccess: true,
        description: 'Sending the Access Token',
        token: token
    });
};

```

when i run the application i am getting the token in `console.log` but 
How can I pass token in header and store it in localStorage of browser?
