Shopify Functions - Introduction and Overview

👨‍🎓 Automate More. Build Faster. Land Better Opportunities with AI: https://codingwithjan.com/ai-develope... 🎬 About this Video Shopify Functions are a powerful new way to extend and customize Shopify by writing your own backend code. For the first time, Shopify opens up parts of its backend logic to developers. In this video I explain how it all fits together: the three layers of a store (database, backend, frontend), what "backend logic" actually means, and how Functions differ from traditional apps (they reach areas apps can't, like checkout discount and shipping logic, run on Shopify's own infrastructure in under five milliseconds, and scale to the biggest sale events). I walk through the function lifecycle, what you need to get started, and then build and deploy the volume-discount demo from the docs so you can watch a real function run live on Shopify's infrastructure. ⏳ Timestamps 00:00 Intro 00:37 The Three Layers of a Store 02:16 Functions vs Traditional Apps 06:01 The Function Lifecycle 06:53 What You Need to Get Started 08:39 Building the Volume Discount Demo 12:56 Testing the Function Live 14:54 Next Steps 🔎 SEO Description An introduction and overview of Shopify Functions, the new way to customize Shopify's backend logic with your own code. Learn how a store is structured across database, backend and frontend layers, how Functions differ from traditional apps (reaching checkout discount and shipping logic, running on Shopify's infrastructure in under five milliseconds, scaling automatically, and integrating settings directly into the admin), the full function lifecycle, and the requirements to get started (a WebAssembly-compilable language like Rust, a package manager, ngrok, a Partner account and a dev store). Includes a hands-on demo building and deploying a volume-discount function from the Shopify docs.
