With vtex.js you can manipulate catalog and checkout data from the client's side, customizing the store template with additional information according to your business needs.

vtex.js depends on jQuery, so make sure it is included in the page before vtex.js.

You may insert all the modules from vtex.js in your store:

Or you may insert the modules individually:

Now you have access to various methods to use VTEX APIs through the objects vtexjs.catalog and vtexjs.checkout.

vtex.js is made up of several modules, which contain functions that are used to communicate with VTEX services.

The modules reside in the global vtexjs object. When you include a module script, an object with all methods is created to access the APIs of that module. For example, by adding the Checkout module, you now have the vtexjs.checkout object, with several methods for accessing the Checkout API.

The Checkout module handles customer purchase data.

Checkout adds different data needed to create an order: client profile data, address, shipping, items data, and others.

The OrderForm is the structure that contains this clustered data. It consists of several sections, each with useful information that can be accessed, manipulated, and (possibly) changed. To learn more, refer to the orderForm documentation.

The Catalog module gets data related to your store's products.

Now vtex.js can be linked to other repositories for development.
