Next.js Commerce refresh. (#966) We're making some updates to Next.js Commerce. Everything prior to this commit marks what we're calling [`v1`](https://github.com/vercel/commerce/releases/tag/v1) as a point in time to be able to reference and still use going into the future. The current architecture of Commerce is a multi-vendor, interoperable solution, including: - [Shopify](https://shopify.vercel.store/) - [Swell](https://swell.vercel.store/) - [BigCommerce](https://bigcommerce.vercel.store/) - [Vendure](https://vendure.vercel.store/) - [Saleor](https://saleor.vercel.store/) - [Ordercloud](https://ordercloud.vercel.store/) - [Spree](https://spree.vercel.store/) - [Kibo Commerce](https://kibocommerce.vercel.store/) - [Commerce.js](https://commercejs.vercel.store/) - [SalesForce Cloud Commerce](https://salesforce-cloud-commerce.vercel.store/) All features can be toggled on or off, and it's easy to change between commerce providers. To support this, we needed to create a ["commerce metaframework"](https://github.com/vercel/commerce/blob/d1d9e8c4343e70d72df6e00ec95f6ea4efbb7c54/packages/commerce/new-provider.md) where providers could confirm to an API spec to add support for Next.js Commerce. While this worked and was successful for `v1`, we have different design goals and ambitions for `v2`. **What You Need To Know** - `v1` will not be updated moving forward. If you need to reference `v1`, you will still be able to clone and deploy the version tagged at this release. - `v2` will be shifting to be a single provider vs. provider agnostic. Other providers are welcome to fork this repository and swap out the underlying `lib/` implementation that connects to the selected commerce provider (Shopify). This architecture was chosen to reduce the surface area of the codebase, remove the intermediate metaframework layer for provider-interoperability, and enable usage with the latest Next.js and React features. - We will be sharing more about `v2` in the future as we continue to iterate before the marked release.
