Quick Shopify Dev Tip #2

If you're building a Shopify App that injects code into the storefront, make sure it can also remove that code automatically on install. Nothing is worse than a customer trying to remove your app and having to dig into their theme's code and then angrily leaving you a review afterwards.

To make this a smooth process on your end, what you can do is create separate snippets with the code you want on the store, then update theme.liquid or any other template/section with {% render %} tags (see this post to learn about the new render tag) to have your code be included in the theme itself.
