meteor-braintree-helper

A meteor package wrapped for the braintree

• braintree npm 1.23.0 (server) - https://www.npmjs.com/package/braintree
• braintree javascript client v2 (client) - https://js.braintreegateway.com/v2/braintree.js

Server-Side Usages

There are two possible usages:

i. Braintree object is directly ported from Npm braintree Braintree = Npm.require('braintree');, so you can use it to do basically anything.

ii. BraintreeHelper is a singleton helper object for calling braintree API. It provides Meteor.wrapAsync on the asynchronous API calls for convenience.

Sample Code for BraintreeHelper

i. In Meteor.startup (or any other places), connect braintree server, i.e.

Meteor.startup(function() {
  var config = {
    environment: Braintree.Environment.Sandbox, // OR production
    publicKey: 'YOUR PUBLIC KEY,
    privateKey: 'YOUR PRIVATE KEY',
    merchantId: 'YOUR MERCHANT ID'
  };
  BraintreeHelper.getInstance().connect(config);
});

ii. To create a client token, i.e.

  var options = {}; // fill it, if any
  var response = BraintreeHelper.getInstance().clientTokenGenerate(options);
  var clientToken = response.clientToken;

iii. To create a transaction, i.e.

  var options = {
    amount: 10,
    paymentMethodNonce: 'NONCE FROM CLIENT'
  };
  var response = BraintreeHelper.getInstance().transactionSale(options);

iv. Other API calls Currently, only two API calls are wrapped with Meteor.wrapAsync (gateway.clientToken.generate and gateway.transaction.sale) as shown above in ii) and iii). You are welcome to contribute by wrapping up the other calls as well.

Or as a workaround, you can obtain the gateway object by BraintreeHelper.getInstance().getGateway(), which would allow you to call any other APIs asynchronously (of course you can still do Meteor.wrapAsync around them), i.e.

  var gateway = BraintreeHelper.getInstance().getGateway();
  gateway.clientToken.generate(); // The original API call for generating clientToken

Client-Side Usage

In client side, you can access the braintree object from the Braintree javascript client( https://js.braintreegateway.com/v2/braintree.js) directly. e.g.

  var clientToken = GET_CLIENT_TOKEN_FROM_SERVER(); // e.g. through Meteor.call()
  braintree.setup(clientToken, 'dropin', {
    container: 'dropin',
    paymentMethodNonceReceived: function(event, nonce) {
      // You can can send the nonce back to server to proceed with the payment, e.g. through Meteor.call()
    }
  }
