# widget-zone-must-be-string-literal - ESLint plugin rules

This rule requires the `zone` property in `defineWidgetConfig` to be a string literal or an array of string literals.

## Severity

`error`. This rule is enabled in the [recommended](https://docs.medusajs.com/resources/lint#recommended) preset.

## What it Targets

This rule targets files in your project's `src/admin/widgets` directory. It reports a `zone` property whose value isn't a string literal, an array of string literals, or a template literal without expressions.

The following code is reported by the rule:

```tsx title="src/admin/widgets/product-widget.tsx"
import { defineWidgetConfig } from "@medusajs/admin-sdk"

const ZONE = "product.details"

export const config = defineWidgetConfig({
  zone: ZONE,
})
```

Instead, use a string literal:

```tsx title="src/admin/widgets/product-widget.tsx"
import { defineWidgetConfig } from "@medusajs/admin-sdk"

export const config = defineWidgetConfig({
  zone: "product.details",
})
```

## Why it's Important

Medusa statically analyzes widget files to determine the zones a widget is injected into. A dynamic `zone` value can't be resolved at build time, so the widget may not render in the expected location.

Learn more in the [Admin Development Constraints documentation](https://docs.medusajs.com/learn/fundamentals/admin/constraints).

## Fixable

This rule is auto-fixable. Run the linter with the `--fix` option to apply the fix automatically.
