I have a front end application with a contact form for clients, and my goal is to be able to send emails from the form the client will fill out to the company startup email. For that , I already validated the form and my intention is to send back the information to my back end application (node.js) to send the email. The only problem is that form some reason on the vue.js webpack template, I get the Cannot POST error. So what I have tried so far was web sockets which didnt work because I cant seem to use the POST HTTP method, I also tried using vue-resource with the this.$http.post() method which didn't work either because I get the following error message:
Uncaught TypeError: Cannot read property 'post' of undefined
the following is my vue instance with the contact form :

the following is my main.js on the vue webpack template.

the following is my back end application so far:
let express = require('express'), app = express(),
path = require('path'), bodyParser = require('body-parser'),
socket = require('socket.io'),urlencodedParser = bodyParser.urlencoded({ extended: false });
let server = app.listen(5000, ()=>{
console.log('listening to requests...');
});
let io = socket(server);
app.get('/', function(req, res) {
res.sendFile(path.join(__dirname + '/index.html'));
});
// io.on('connection', (socket)=>{
// console.log('made a connection!');
// socket.on('email', (data)=>{
// console.log(data);
// });
// });
app.post('http://localhost:5000', urlencodedParser,(req, res)=>{
console.log(req.body);
});
When I click on the submit button, what I want is to post the data to my back end in order to log what has been sent to the console for the time being. My final goal is to send an email.So far, this is the error message I am receiving:
Failed to load http://localhost:5000/: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access.
