Efficient theming systems require an architecture that supports different users at various stages. Shopify has been pioneering that with Liquid themes for years, in this talk I'll explore the critical components that make it possible, and how to build them from authoring to rendering.
Liquid demonstrates how a secure and human-friendly DSL can power customizable and lightning-fast storefronts. While the Liquid themes architecture showcases how to build bridges between technical and non-technical users through a visual editor.
On the developer tooling side, I'll show how supporting and optimizing workflows through a language server and a VS Code extension are crucial to help, encourage, and guide developers in building optimal solutions for merchants—from both performance and customizability perspectives.
Finally, I'll approach the runtime that powers this entire ecosystem at scale and share the techniques to evolve your platform balancing innovation, backward compatibility, and collaboration across diverse user personas.
