@shopify/theme-product

Getting Started

Theme Scripts can be used in any theme project. To take advantage of semantic versioning and easy updates, we recommend using NPM or Yarn to include them in your project:

yarn add @shopify/theme-product

and then import the functions you wish to use through ES6 imports:

import * as product from '@shopify/theme-product';

If you prefer not to use a package manager, you can download the latest version of Theme Product and include it in your project manually from the following links:

These files make Theme Product accessible via the Shopify.theme.product global variable.

Usage

theme-product.js helps developers work with and navigate a Shopify product object. A common use is find a product variant based on a selection of product options, e.g. the variant of a t-shirt which is size S and color black.

Product object

When using the following methods, make sure your product JSON object is valid. Usually it is the Product object generated from Liquid. Note: The JSON generated from Liquid is different from the conventional {{ json }} filter due to some properties not being exposed.
