So I checked out the git branch for Next.js Commerce (<a href="https://github.com/vercel/commerce/" rel="nofollow">https://github.com/vercel/commerce/</a>). Aside from the missing documentation, there seems to be a lot of touch points where the code is tightly integrated with BigCommerce's npm library.<p>At this point, it does not feel like the headless ecommerce part swappable. I'm sure that with time, the team will probably extract this out so that it's more plug and play (<a href="https://github.com/vercel/commerce/issues/2" rel="nofollow">https://github.com/vercel/commerce/issues/2</a>) or will require the libraries (ie. for Shopify, etc) to follow a certain pattern.<p>If anyone on the Next.js Commerce team is reading this, the other thing I noticed is that this requires a BigCommerce account. Would be great to have a functionality where one could test out all the end points without needing a third party service in local development. I happen to have a sandbox BigCommerce shop, but there's quite a few steps to get one set up.
