to

to: string

Defined in: packages/core/src/fields/upload/types.ts:28

The slug of the media collection that stores uploaded files for this field.

Must match a media collection defined via a storage adapter’s defineMediaCollection(). After running vex generate, this is typed as MediaCollectionSlug — a union of all media collection slugs in the project. Before generation, it falls back to string.

Config validation (in media/config.ts) also checks at runtime that the slug exists in VexConfig.mediaCollections.

Example

upload({ to: "images", label: "Featured Image" })
