External frontend deployment
If you've chosen to build an external frontend for your Gadget app, you'll need to deploy it to a hosting platform. Frontend deployment can be complicated, which is why Gadget recommends using the built-in frontend when possible, but if you want to use an external frontend, you can use one of the following deployment guides.
If you are trying to deploy a Shopify app and don't already have one connected, you must already have a Gadget backend app setup connected to Shopify and a working Shopify CLI-based frontend.
To create these, you can follow Gadget's Shopify CLI Connection tutorial.
