Imagine you could purchase items from your store, with pure JavaScript in the browser. How would it look like? Here's what I came up with. Forks & comments much appreciated! #nobackend #dreamcode

payments_dreamcode.js

// purchase a product with a credit card
purchase('productId')
.using( {
  cc: "4556934156210213",
  valid: "2016-10",
  csc: "123"
} )

// purchase a product with paypal
purchase('productId')
.using( 'paypal' )

// upgrade a user to a pro plan, payment via paypal.
purchase(
  account.upgradoTo( 'pro' )
).using('paypal')

Bitcoin payments can be easily added with:
http://bitcore.io/playground/#/address and #/transaction

// ...
.using( 'bitcoin/bitcore' )
.payment_request({
  address: "1address...",
  amount: 10000, // satoshis
})

or some more sophisticated and complete example like:

// ...
.using(['bitcoin/bitcore', 'bitcoin/blockchain_info', 'bitcoin/blockr_io'])
.to({
  address: "1address...",
  amount: 10000, // satoshis
}).sign({
  privateKey: "5pvtkey...." // signs the transaction, doesn't send the private key
}).propagate(['blockchain_info', 'blockr_io'])

super-alpha version, need to be discussed I think, also what about multisig? Anyway dreamcode ftw!

FYI, there's a standard for this now.
Although the API is a bit more complex.
