Wrap Stripe.js async methods to return promises
npm install stripe-as-promised> Wrap Stripe.js's asynchronous methods to return promises instead of calling callbacks.
``sh`npm
$ npm install stripe-as-promised
#### stripeAsPromised(Stripe, Promise) -> promisifedStripe
##### Stripe
Required
Type: function
The Stripe.js library
##### Promise
Required
Type: function
A Promise constructor
The returned promisified object promisifes the following methods in addition to exposing utility methods:
* card.createToken
* bankAccount.createToken
* piiData.createToken
* bitcoinReceiver.createReceiver
* bitcoinReceiver.pollReceiver
* bitcoinReceiver.getReceiver (undocumented)
Below is an abbreviated version of Stripe's documented example for creating a token:
`js
// card === {number: '42...', ...}
Stripe.card.createToken(card, stripeResponseHandler);
function stripeResponseHandler(status, token) {
if (token.error) {
console.error('Tokenization failed');
} else {
console.log('Created token', token.id);
}
}
`
The same logic with stripe-as-promised would be written as:
`js
var stripe = stripeAsPromised(Stripe, Promise);
stripe.card.createToken(card)
.then(function (token) {
console.log('Created token', token.id);
})
.catch(function (err) {
console.error(err);
});
`
For handling bitcoin transactions, you'll probably want to avoid using the pollReceiver method as-is. cancelReceiverPoll does not notify the callback passed to pollReceiver of the cancellation, so the following code could result in a promise that never resolves:
`js``
stripe.bitcoinReceiver.createReceiver(payment)
.then(function (receiver) {
return stripe.bitcoinReceiver.pollReceiver(receiver.id);
})
.then(function (receiver) {
console.log('Payment received!');
})
.catch(function (err) {
console.error('Payment error', err);
});
If the receiver is never filled, neither statement is printed. In your application, you'll probably want to implement your own polling implementation that treats cancellations as errors that can be caught and handled downstream.
