Shopify CLI
The Shopify CLI is the command-line tool merchants and developers use to scaffold, develop, deploy, and validate Shopify apps and themes. It is the primary local-development surface for accessibility-aware theme editing.
Detailed explanation
Shopify CLI 3.x covers app development (`shopify app dev`), theme development (`shopify theme dev`), theme push/pull/check, and store-level GraphQL execution (`shopify store execute`). The `shopify theme check` subcommand runs Theme Check, Shopify's static analyzer for Liquid templates — including a small set of accessibility checks (image-alt-text, valid-html, etc.) but not a full WCAG audit.
For accessibility work specifically, CLI is the offline-edit-and-push path: pull the theme, edit Liquid + CSS in your local editor with full diff visibility, push back. Compared to editing live in the Shopify admin, the CLI workflow gives you Git history of every accessibility change.
How this applies to Shopify stores
AccessComply's deterministic fixes are pushed via the Shopify Admin API (not CLI), but merchants who want to review every fix before publishing can connect their store to GitHub via the Shopify GitHub integration and have AccessComply open PRs against the theme repo. The Shopify CLI is the canonical way to develop the theme code those PRs touch.
