I'm new to Shopify development and I have a few questions -
I followed the tutorial (official Youtube channel and documentation) to build an embedded Admin App using React and Node.
What I want to be able to do - when installing an app also add a piece of UI to the storefront for example - 1. An announcement bar across all pages. 2. A gallery that the user can drag and drop using the page editor.
Plus this piece in the store front should get config from the admin page.
I can't find any resources for that, any suggestions?
