Close this issue Delivery: Use Remix template for function app tutorial and sample app
Update the Delivery Customization app sample app to use Remix.

What approach did you choose and why?

• Followed Shopify App Template - Remix to create a remix app template.
• Followed the example PR Rewrite payment customizations app with Remix in the issue.
• app.delivery-customization.$functionId.$id.jsx authored-by: David Cameron @davejcameron
• For prototyping, I created this repo delivery-customizations-app. For 🎩, in your terminal

dev clone delivery-customizations-app
npm install
npm run setup
npm run dev
npm run deploy

The only issue I ran into is that the CLI doesn't like shopify.app.toml only having scopes in there. I had to delete the file for the dev to work.

Turns out it's not because the file exists, but it's because there's a space between scopes 🤦 I've pushed a commit with the fix.
