If you ever had the need to use Intuit's Customer Account Data(CAD) and are using NodeJS we have definitely been in the same boat together.  The boat where there is about ten anchors holding you back because Intuit does not have a module for NodeJS yet to help you.  Sound familiar?  If so, look no further, as I implemented their CAD API with JavaScript and put it in a NPM module called intuit-cad.  This allows you to effortlessly authenticate your customers and get access to their institution's data such as transactions and accounts.
