How to create a storefront to use the plugin?

I would like to ask about the specific process of developing plug-ins because there are too few teaching about shopify plug-in development in China, so I found here. I want to develop a plug-in for the front desk, but why do I get a background interface every time I click the link? I want this plug-in to serve front desk users

Hi,

I’m not 100% sure exactly what you’re looking for - but you can read this doc for an intro to building Shopify apps: https://shopify.dev/docs/apps/build/scaffold-app

And this doc will show you how to build apps that customise the front-end of a store, which we call theme app extensions: About theme app extensions
