Polymer POST http://localhost:3000/ 404 (Not Found) - firebase

Question

I am trying to create a charge for Stripe using node.js. So I have followed Firebase method to see if I could get this working:
For clarity, I have left out the polymer elements imports. Assume all is well.
/charge.html:
<dom-module id="stripe-charge">
<template>
<script>
var firebaseStripe = new Firebase('https://blahblah.firebaseio-demo.com/');
firebaseStripe.set({
var stripe = require("stripe")("sk_test_blahblah");
var stripeToken = request.body.stripeToken;
var charge = stripe.charges.create({
amount: 1000, // amount in cents, again
currency: "gbp",
source: stripeToken,
description: "Example charge"
}, function(err, charge) {
if (err && err.type === 'StripeCardError') {
// The card has been declined
}
});
</script>
</template>
<script>
Polymer({
is: 'stripe-charge',
});
</script>
</dom-module>
index:
<section data-route="charge">
<stripe-charge></stripe-charge>
</section>
routing.html:
page('/charge', function () {
app.route = 'charge';
});
page({
hashbang: true
});
form:
<form is="iron-form" id="myForm" action="http://localhost:3000/#!/charge" method="post">
<input type="hidden" is="iron-input" id="amount" name="amount" bind-value="{{total}}">
<input type="hidden" id="stripeToken" name="stripeToken"/>
<input type="hidden" is="iron-input" id="stripeEmail" name="stripeEmail" bind-value="{{emailInput}}"/>
</form>
<paper-button class="fullBtn" id="customButton" on-click="stripe">
<iron-icon icon="icons:credit-card"></iron-icon>
Pay
</paper-button>
When I press the pay button, fill out card details etc, then hit the Strip pay button, I get the green but when it goes to the charge page, I get POST http://localhost:3000/ 404 (Not Found) Somehow it's not going to the page. Any ideas? I feel there will be more errors but for now, I want to get that page. Firebase issue?

Answer 1

Change your url be a true path, not a hash location:
<form is="iron-form" id="myForm" action="http://localhost:3000/charge" method="post">
You need to run a server that accepts the post and then makes a call to Stripe with your private key, you cannot run Stripe as a pure client-only process.
The first step in the browser calls stripe and packages up the supplied credit card information, but then you need to provide that token to your server. Otherwise anyone could submit charges on your behalf, including refunds!
