Is there any concern for new apps to use Script Tag

Shopify Apps

Topic summary

A new Shopify app developer asks if using ScriptTag for widget injection is safe given theme app extensions are mandatory, and seeks clarity on deprecation timeline, Online Store 2.0 limitations, and performance impacts. They plan to place the script inside theme blocks.

One response claims ScriptTag “won’t be deprecated,” citing documentation, but provides no specifics. A later post shares a Shopify email announcing the deprecation of checkout.liquid, script tags, and additional scripts on the thank you and order status pages, with a sunset date of August 28, 2025; the Shopify Scripts sunset is also extended to that date.

Implications: Developers should plan to migrate away from script tags for checkout and post-purchase surfaces, adopting Checkout UI Extensions and Functions as the recommended replacements. Theme app extensions remain the supported approach for theme integration.

Open items: The thread does not conclusively address script tag limitations specific to Online Store 2.0 themes or detailed performance considerations. The discussion remains partially unresolved pending official documentation details and scope clarifications.

Hi,
I’m new in Shopify development and have started developing the app for Shopify.
As I understand, supporting theme app extension is mandatory for new apps but is there any depreciation timeline for script tag?
I want to implement the widget injection with a script tag. I will also put the script tag inside the theme blocks and fill it with the script tag.
So, I need to understand the concerns of the script tags.
1- Will it be deprecated?
2- Does it have any limitations in new themes (2.0 themes)?
3- Any performance issues?

Thank you

Hello,

I 've got an email today saying

In tandem, we will announce the deprecation of checkout.liquid, script tags, and additional scripts on the thank you and order status pages. These features will sunset on August 28, 2025. We’re also extending the Shopify Scripts sunset date to August 28, 2025. Until then, Shopify Scripts will continue to work alongside Checkout UI Extensions and Functions.

So, as I understand script tags will be depreciated on August 28, 2025 and the promote the use of Checkout UI Extensions and Functions.

Something to be considered
