Could we get some clarification from Shopify on this? There are 800kB of assets being loaded from “/shopify-cloud/checkout-web/assets” on every page, which is crazy since it’s not even clear what utility it provides outside of checkout.
Topic summary
Merchants are experiencing significant drops in Lighthouse page speed scores (from 90+ to 75) due to large Shopify-generated JavaScript files, particularly app.latest files from cdn.shopify.com/shopifycloud/checkout-web/assets/.
Key Issues:
- Files appear to be core Shopify assets consuming 800kB+ of network payload
- Loading on every page, even outside checkout flows
- Merchants have no control over these files or ability to optimize them
- The specific purpose and utility of these assets remains unclear
Current Status:
- Multiple users report similar problems with checkout-web assets
- One response provided generic optimization tips (image compression, minifying CSS/JS, removing unused apps) but didn’t address the core Shopify files
- Community members are seeking official clarification from Shopify on why these large assets are necessary site-wide and whether they can be delayed or optimized
Unresolved: The discussion remains open with no official Shopify response explaining the files’ purpose or providing solutions for the performance impact.
