CommerceProvider

Provider component that creates the commerce context for children.

import { CommerceProvider } from 'nextjs-commerce-shopify';

const App = ({ children }) => {
  return (
    <CommerceProvider
      config={{
        domain: 'myshop.shopify.com',
        token: 'XXXXXX',
        currenyCode: 'SGD'
      }}
    >
      {children}
    </CommerceProvider>
  );
};

export default App;

The config takes:

domain: Shopify domain. This is required.
token: Shopify Storefront API Access Token. This is required.
currencyCode: Currency code to use in store. Defaults to your Shopify default currency.
locale: Used for currency format and if your Shopify supports translated content. Defaults to en-US.

useCommerce

import { useCommerce } from 'nextjs-commerce-shopify';

const { checkout, shop } = useCommerce();
