# no-wildcard-with-specific-fields - ESLint plugin rules

This rule disallows combining the `*` wildcard with specific top-level fields in a `query.graph` or `useQueryGraphStep` field selection, because `*` silently drops those specific field selections.

This rule is available since Medusa [v2.18.0](https://github.com/medusajs/medusa/releases/tag/v2.18.0).

## Severity

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

## What it Targets

This rule targets usages of `query.graph` and `useQueryGraphStep` anywhere in your project. It reports a `fields` array that contains both the `*` wildcard and one or more specific top-level fields.

The following code is reported by the rule:

```ts title="src/workflows/example.ts"
const { data } = await query.graph({
  entity: "cart",
  fields: ["*", "total"],
})
```

Remove the specific top-level fields if you want all of the entity's own fields, since `*` already selects them:

It's highly discouraged to use `*` in production code, as it can lead to performance issues with large data models. It's better to explicitly list the fields you need.

```ts title="src/workflows/example.ts"
const { data } = await query.graph({
  entity: "cart",
  fields: ["*"],
})
```

Or remove `*` and list only the fields you need, including any computed fields:

```ts title="src/workflows/example.ts"
const { data } = await query.graph({
  entity: "cart",
  fields: ["id", "total", "subtotal"],
})
```

Relation selections such as `items.*` or `items.title` are not affected by this rule. They are scoped to a relation and are kept even when `*` is present, so the following is valid:

```ts title="src/workflows/example.ts"
const { data } = await query.graph({
  entity: "cart",
  fields: ["*", "items.*", "items.title"],
})
```

## Why it's Important

The `*` wildcard selects all of an entity's own scalar fields. It does not include computed fields such as `total` or `subtotal`. When you combine `*` with a specific top-level field like `"total"`, the specific field is silently ignored and the response won't contain it.

Listing only the fields you need, without `*`, is the safest approach when you require computed or non-default fields.

## Fixable

This rule isn't auto-fixable.

## Turn it Off

To turn off this rule, set it to `off` in your ESLint configuration:

```ts title="eslint.config.ts"
import { defineConfig } from "eslint/config"
import medusa from "@medusajs/eslint-plugin"

export default defineConfig([
  ...medusa.configs.recommended,
  {
    rules: {
      "@medusajs/no-wildcard-with-specific-fields": "off",
    },
  },
])
```

Or disable it for a single line using an inline comment:

```ts
// eslint-disable-next-line @medusajs/no-wildcard-with-specific-fields
const { data } = await query.graph({ entity: "cart", fields: ["*", "total"] })
```
