# InferMaybeRef

> Unwrap a Vue `Ref<U>` to its inner `U` - leaves non-ref types unchanged.

- Package: `@maz-ui/utils`
- Import: `import type { InferMaybeRef } from '@maz-ui/utils/ts-helpers/InferMaybeRef'`
- Web: https://maz-ui.com/ecosystem/utils/types/infer-maybe-ref

Useful when authoring composables that accept either a plain value or a `Ref`, and you want a unified type for the inner value.

## Usage

```ts
import type { InferMaybeRef } from '@maz-ui/utils'
import { ref } from 'vue'

const a = ref(42)
const b = 42

type A = InferMaybeRef<typeof a> // number
type B = InferMaybeRef<typeof b> // number
```

## API

```ts
import type { Ref } from 'vue'

type InferMaybeRef<T> = T extends Ref<infer U> ? U : T
```

## Notes

- Pairs well with Vue's built-in [`unref()`](https://vuejs.org/api/reactivity-utilities.html#unref), which provides the same behaviour at runtime.
