Summary

If you are integrating your Shopify theme with a third-party app you may want to access some of the globally available functions. Since our themes utilize Alpine.js this is done a bit differently than normal.

How to

The first step is to access the app object. This object contains all the exposed functions and is stored in the _x_dataStack array of the html element. Here is how to access it:
​

var app = document.querySelectorAll('html')[0]._x_dataStack[0];

From here you can call any of the functions available in the Paper toolkit. For example if you want to call cart.updateCart() you could do the following.

app.updateCart(true);
