Importing Node Modules With JavaScript

Question

I apologize for the simple question, but I'm pretty new to web development and JavaScript.

I want to import a package I've installed using npm, specifically shopify-buy following the guide here: https://shopify.github.io/js-buy-sdk/

The package is in my node_modules folder and I'm trying to import it into a JavaScript document using import Client from 'shopify-buy';

When I try to load everything up in Chrome, I get an error on the import line

Uncaught SyntaxError: Unexpected identifier

The Firefox error is a bit different: import declarations may only appear at top level

What am I doing wrong?

Edit:

The import line is the first line in my JavaScript file. And my HTML file is properly linked to the JS file (I think).

shopify.js

// Functions for SHOPIFY
import Client from 'shopify-buy';

const client = Client.buildClient({
    domain: 'xxxxx.myshopify.com',
    storefrontAccessToken: 'xxxxx'
});

index.html

<script src="javascript/shopify.js"></script>

If you want to use npm modules via the syntax, like import sth from "something" for browsers, you'd need to set up a module bundler and ES6 compiler, such as Webpack and Babel. You'd need to google them and find tutorials for setting up them accordingly.

An easy way to use the SDK seems to be using the CDN, since it's already been built for browsers to understand. Something like:

index.html

<script src="http://sdks.shopifycdn.com/js-buy-sdk/v1/latest/index.umd.min.js"></script>
<script src="javascript/shopify.js"></script>

shopify.js

const client = ShopifyBuy.buildClient({
    domain: 'your-shop-name.myshopify.com',
    storefrontAccessToken: 'your-storefront-access-token'
});

console.log(client);
