John's Notes

The Next.js Commerce Section and below are cloned OOTB from NextJS Commerce Starter. Here are some of my notes:

1. This app has two APIs currently: The Commerce API and the app-specific Futurecaster API.
   • BigCommerce, Swell, and Shopify APIs extend the OOTB NextJS Commerce API.
   • Futurecaster API is currently in Supabase. Later, I might add Hasura or some other stuff.
   • The implementations are moderately different; Commerce API uses higher order hooks and I'm not about that life.
   • Both APIs use isomorphic fetch for HTTP requests. Server-side is Vercel fetch which wraps node-fetch.
2. The APIs are quasi-MVC. NextJS page/api section is like server routes and the framework folder is like a services directory.
   • handlers is a subfolder used to catch subservices when the top level services is complicated. As such, in my opinion, handler files are optional / as needed.
3. Site is a static prerender NextJS pattern with SWR for state management.

Integrations

Next.js Commerce integrates out-of-the-box with BigCommerce and Shopify. We plan to support all major ecommerce backends.

Considerations

• framework/commerce contains all types, helpers and functions to be used as base to build a new provider.
• Providers live under framework's root folder and they will extend Next.js Commerce types and functionality (framework/commerce).
• We have a Features API to ensure feature parity between the UI and the Provider. The UI should update accordingly and no extra code should be bundled. All extra configuration for features will live under features in commerce.config.json and if needed it can also be accessed programatically.
• Each provider should add its corresponding next.config.js and commerce.config.json adding specific data related to the provider. For example in case of BigCommerce, the images CDN and additional API routes.
• Providers don't depend on anything that's specific to the application they're used in. They only depend on framework/commerce, on their own framework folder and on some dependencies included in package.json

Configuration

How to change providers

Open .env.local and change the value of COMMERCE_PROVIDER to the provider you would like to use, then set the environment variables for that provider (use .env.template as the base).

The setup for Shopify would look like this for example:

COMMERCE_PROVIDER=shopify
NEXT_PUBLIC_SHOPIFY_STOREFRONT_ACCESS_TOKEN=xxxxxxxxxxxxxxxxxxxxxxxxxxxx
NEXT_PUBLIC_SHOPIFY_STORE_DOMAIN=xxxxxxx.myshopify.com

And change the tsconfig.json to resolve to the chosen provider:

  "@framework": ["framework/shopify"],
  "@framework/*": ["framework/shopify/*"]

That's it!

Features

Every provider defines the features that it supports under framework/{provider}/commerce.config.json

How to turn Features on and off

NOTE: The selected provider should support the feature that you are toggling. (This means that you can't turn wishlist on if the provider doesn't support this functionality out the box)

• Open commerce.config.json
• You'll see a config file like this:

  {
      "features": {
          "wishlist": false
      }
  }

• Turn wishlist on by setting wishlist to true.
• Run the app and the wishlist functionality should be back on.
