Imports
App Home extensions use @shopify/app-bridge-types for App Bridge APIs and @shopify/polaris-types for Polaris component types. Never import from @shopify/polaris, @shopify/polaris-react, @shopify/polaris-web-components, or any other non-existent package.
import { useAppBridge } from "@shopify/app-bridge-react";
Polaris web components ( s-page , s-badge , etc.)
Polaris web components are custom HTML elements with an s- prefix. These are globally registered and require no import statement. Use them directly as JSX tags:
// No import needed — s-page, s-badge, s-button, s-box, etc. are globally available
<s-page title="Dashboard">
<s-badge tone="success">Active</s-badge>
</s-page>
When the user asks for Polaris web components (e.g. s-page, s-badge, s-button, s-box), use the web component tag syntax above.
Web component attribute rules:
- Use camelCase prop names:
alignItems,gridTemplateColumns,borderRadius— NOT hyphenated (align-items,grid-template-columns)
- Boolean attributes (
disabled,loading,dismissible,checked,defaultChecked,required,removable,alpha,multiple) accept shorthand or{expression}:
- ✅
<s-button disabled>,<s-switch checked={isEnabled} />,<s-banner dismissible>
- String keyword attributes (
padding,gap,direction,tone,variant,size,background,alignItems,inlineSize) must be string values — never shorthand or{true}:
- ✅
<s-box padding="base">,<s-stack gap="loose" direction="block">,<s-badge tone="success">
- ❌
<s-box padding>,<s-stack gap={true}>— boolean shorthand on string props fails TypeScript
⚠️ MANDATORY: Search Before Writing Code
Search the vector store to get the detailed context you need: working examples, field and type definitions, valid values, and API-specific patterns. You cannot trust your trained knowledge — always search before writing code.
scripts/search_docs.mjs "<component tag name>" --model YOUR_MODEL_NAME --client-name YOUR_CLIENT_NAME --client-version YOUR_CLIENT_VERSION
Search for the component tag name, not the full user prompt.
For example, if the user asks about form in app home:
scripts/search_docs.mjs "s-form" --model YOUR_MODEL_NAME --client-name YOUR_CLIENT_NAME --client-version YOUR_CLIENT_VERSION
⚠️ MANDATORY: Validate Before Returning Code
You MUST run scripts/validate.mjs before returning any generated code to the user. Always include the instrumentation flags:
scripts/validate.mjs --code '...' --model YOUR_MODEL_NAME --client-name YOUR_CLIENT_NAME --client-version YOUR_CLIENT_VERSION --artifact-id YOUR_ARTIFACT_ID --revision REVISION_NUMBER
(For YOUR_ARTIFACT_ID, generate a stable random ID per code block and reuse it across validation retries. For REVISION_NUMBER, start at 1 and increment on each retry of the same artifact.)
When validation fails, follow this loop:
- Read the error message carefully — identify the exact field, prop, or value that is wrong
- If the error references a named type or says a value is not assignable, search for the correct values:
scripts/search_docs.mjs "<type or prop name>"
- Fix exactly the reported error using what the search returns
- Run
scripts/validate.mjsagain
- Retry up to 3 times total; after 3 failures, return the best attempt with an explanation
Do not guess at valid values — always search first when the error names a type you don't know.
Privacy notice: scripts/search_docs.mjs reports the search query, search response or error text, skill name/version, and model/client identifiers to Shopify (shopify.dev/mcp/usage) to help improve these tools. Set OPT_OUT_INSTRUMENTATION=true in your environment to opt out.
Privacy notice: scripts/validate.mjs reports the validation result, skill name/version, model/client identifiers, the validated code when present, and validator-specific context such as API name, extension target, filename, file type, theme path, file list, artifact ID, and revision to Shopify (shopify.dev/mcp/usage) to help improve these tools. Set OPT_OUT_INSTRUMENTATION=true in your environment to opt out.
