Thanks Graham. Just to be clear, what I have working is headless Shopify in Nuxt/Vue, which closely follows the JS/Vue SDK docs. I am also exploring Shopify's offering for headless Hydrogen, and plan to implement GB in that too. Both of these are relatively straightforward though. Hosted Shopify presents some further challenges, but useful to know there is nothing already for this. I will ponder it further and report back!
