### getEntityAssets

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, entity: T) => Promise<<a href='/reference/typescript-api/entities/asset#asset'>Asset</a>[] | undefined>`}   />

Returns the Assets of an entity which has a well-ordered list of Assets, such as Product,
ProductVariant or Collection.
### updateFeaturedAsset

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, entity: T, input: <a href='/reference/typescript-api/services/asset-service#entityassetinput'>EntityAssetInput</a>) => Promise<T>`}   />


### updateEntityAssets

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, entity: T, input: <a href='/reference/typescript-api/services/asset-service#entityassetinput'>EntityAssetInput</a>) => Promise<T>`}   />

Updates the assets / featuredAsset of an entity, ensuring that only valid assetIds are used.
### create

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, input: CreateAssetInput) => Promise<CreateAssetResult>`}   />

Create an Asset based on a file uploaded via the GraphQL API. The file should be uploaded
using the [GraphQL multipart request specification](https://github.com/jaydenseric/graphql-multipart-request-spec),
e.g. using the [apollo-upload-client](https://github.com/jaydenseric/apollo-upload-client) npm package.

See the [Uploading Files docs](/developer-guide/uploading-files) for an example of usage.
### update

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, input: UpdateAssetInput) => Promise<<a href='/reference/typescript-api/entities/asset#asset'>Asset</a>>`}   />

Updates the name, focalPoint, tags & custom fields of an Asset.
### delete

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, ids: <a href='/reference/typescript-api/common/id#id'>ID</a>[], force: boolean = false, deleteFromAllChannels: boolean = false) => Promise<DeletionResponse>`}   />

Deletes an Asset after performing checks to ensure that the Asset is not currently in use
by a Product, ProductVariant or Collection.
### assignToChannel

<MemberInfo kind="method" type={`(ctx: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, input: AssignAssetsToChannelInput) => Promise<<a href='/reference/typescript-api/entities/asset#asset'>Asset</a>[]>`}   />


### createFromFileStream

<MemberInfo kind="method" type={`(stream: ReadStream, ctx?: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>) => Promise<CreateAssetResult>`}   />

Create an Asset from a file stream, for example to create an Asset during data import.
### createFromFileStream

<MemberInfo kind="method" type={`(stream: Readable, filePath: string, ctx?: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>) => Promise<CreateAssetResult>`}   />


### createFromFileStream

<MemberInfo kind="method" type={`(stream: ReadStream | Readable, maybeFilePathOrCtx?: string | <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, maybeCtx?: <a href='/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>) => Promise<CreateAssetResult>`}   />

<GenerationInfo sourceFile="packages/core/src/service/services/asset.service.ts" sourceLine="67" packageName="@vendure/core" />

Certain entities (Product, ProductVariant, Collection) use this interface
to model a featured asset and then a list of assets with a defined order.

```ts title="Signature"
interface EntityWithAssets extends VendureEntity {
    featuredAsset: Asset | null;
    assets: OrderableAsset[];
}
```
* Extends: [`VendureEntity`](/reference/typescript-api/entities/vendure-entity#vendureentity)



<div className="members-wrapper">

### featuredAsset

<MemberInfo kind="property" type={`<a href='/reference/typescript-api/entities/asset#asset'>Asset</a> | null`}   />


### assets

<MemberInfo kind="property" type={`<a href='/reference/typescript-api/entities/orderable-asset#orderableasset'>OrderableAsset</a>[]`}   />




</div>
<GenerationInfo sourceFile="packages/core/src/service/services/asset.service.ts" sourceLine="79" packageName="@vendure/core" />

Used when updating entities which implement [EntityWithAssets](/reference/typescript-api/services/asset-service#entitywithassets).

```ts title="Signature"
interface EntityAssetInput {
    assetIds?: ID[] | null;
    featuredAssetId?: ID | null;
}
```

<div className="members-wrapper">

### assetIds

<MemberInfo kind="property" type={`<a href='/reference/typescript-api/common/id#id'>ID</a>[] | null`}   />


### featuredAssetId

<MemberInfo kind="property" type={`<a href='/reference/typescript-api/common/id#id'>ID</a> | null`}   />
