Why Migrate to Shopify Functions?
1. Scalability and Performance
Shopify Functions operates on Shopify’s fast and secure backend infrastructure. Unlike Scripts, which run in the storefront’s browser, Functions execute server-side, reducing latency and enhancing performance during high-traffic periods.
2. Customization Flexibility
Shopify Functions support advanced customization of discounts, shipping rates, payment methods, and more without the need for third-party apps or custom storefront adjustments.
3. Maintenance and Updates
Functions are easier to maintain and adapt to future Shopify platform updates compared to Scripts, which may require regular tweaks to remain compatible.
