Answer first
Liquivelte v4 solves a concrete workflow problem.
- Problem
- Shopify themes need Liquid to remain the runtime source of truth, but modern component authoring and hydration still matter.
- Built
- Tokenizer, parser, scope and expression modules, runtime helpers, Vite plugin, fixtures, Vitest contract tests, and Liquid/Svelte hydration rules around loops, scope, component boundaries, and trace data.
- Judgment
- Keeps Shopify/e-commerce as a technical rescue lane while showing compiler-level product engineering beyond theme work.
- Search fit
- Svelte Shopify Liquid compiler; Shopify Liquid hydration; Svelte Shopify theme tooling
