FastStore Section & Component Overrides

When this skill applies

Use this skill when:

• You need to customize the behavior or appearance of a FastStore storefront component beyond what theming and design tokens can achieve.
• You need to replace a native component entirely with a custom implementation.
• You need to inject custom logic or modify props on native components within a section.
• You are working with files in src/components/overrides/.

Do not use this skill for:

• Visual-only changes (colors, typography, spacing) — use the faststore-theming skill and design tokens instead.
• Building custom state management for cart, session, or search — use the faststore-state-management skill.
• Extending the GraphQL data layer — use the faststore-data-fetching skill.
