How do Shopify Functions Work?

Shopify Functions mark a significant departure from the traditional approach by opening up Shopify's backend code to developers for the first time. 

This means developers can now extend or replace key parts of Shopify's backend logic with custom code, offering an unprecedented level of flexibility and customization.

Functions operate inline and synchronously, allowing developers to write code in any language that can compile to WebAssembly. 

This enables developers to leverage familiar tools and languages while benefiting from Shopify's robust infrastructure and global deployment.

For merchants, integrating Functions into their store is effortless. By installing an app, the Function becomes configurable directly within the Shopify Admin interface. 

This means that Functions for discounts, shipping, and payment methods seamlessly integrate with Shopify's native settings, providing merchants with a unified experience.

Initially, Shopify Functions focused on familiar backend logic such as discounts, shipping, and payment methods. 

For instance, developers can create custom discount algorithms or enhance shipping calculations to meet specific business requirements. 

As these functions execute inline, they boast sub-five millisecond performance, ensuring they can handle critical tasks seamlessly, even during peak traffic or flash sales events.

Moving forward, Shopify plans to expand the scope of Functions to include additional features like checkout and cart validations, return validations, and programmable order routing. 

This expansion will further empower developers to build innovative solutions and address complex challenges at scale.
