Remixing Shopify's Admin: How We Made It 30% Faster and AI-Ready (2025) - Shopify

This post details the migration of admin.shopify.com to Remix, resulting in a 30% performance improvement and enhanced AI readiness. Key technical contributions include the introduction of route manifests for a single source of truth for all Admin routes, the adoption of Remix loaders for parallel data fetching and component loading, and the use of Remix actions with zod schemas to enable AI agents like Sidekick to understand and interact with forms and data. The migration also standardized loading experiences with global indicators and smooth view transitions, and implemented intelligent prefetching of loaders to warm the Apollo cache.
