Constructor parameters

Methods

Rijks client includes the following three methods:

getCollection

Description

This asynchronous method handles GET /api/[culture]/collection REST API.

Prototype

async getCollection(params: CollectionRequest): Promise<Result<CollectionResponse>> 

Sample code

const params: CollectionRequest = {searchTerm: "Vermeer"}
const collection: CollectionResponse = await rijks.getCollection(params)

CollectionRequest

This interface contains all the possible parameters handled by getCollection method.

CollectionResponse

This interface contains all the values returned by getCollection method

getCollectionDetails

Description

This method handles GET /api/[culture]/collection/[object-number] REST API.

Prototype

async getCollectionDetails(params:CollectionDetailsRequst) : Promise<Result<CollectionDetailsResponse>>

CollectionDetailsRequst

This interface handles all possible getCollectionDetails parameters.

interface CollectionDetailsRequest {
  objectNumber: string;
  format?: Format;
}

CollectionDetailsResponse

This interface handles getCollectionDetails response.

interface CollectionDetailsResponse {
  elapsedMilliseconds: number;
  artObject: ArtObjectDetails;
  artObjectPage: ArtObjectPage;
}

getCollectionImage

Description

This method handles GET /api/[culture]/collection/[object-number]/tiles REST API.

Prototype

async getCollectionImage(params:CollectionImageRequst) : Promise<Result<CollectionImageResponse>>

CollectionImageRequest

This interface handles all possible getCollectionImage parameters.

interface CollectionImageRequest {
  objectNumber: string;
}

CollectionImageResponse

This interface handles getCollectionImage response.

interface CollectionImageResponse {
  levels: Level[];
}

Interfaces

The following interfaces are used for mapping all API requests and responses. In case of complex structure, interfece are used in order to extends basic features.

Result

This interface handles all REST APIs responses.

interface Result<T extends Respnse> {
  success: boolean;
  status: number;
  data?: T;
  error?: string;
}

Types

In order to implement all features, the following common types have been implemended:

ArtObject

This interface has the following structure:

interface ArtObject {
  links: Link;
  id: string;
  objectNumber: string;
  title: string;
  hasImage: boolean;
  principalOrFirstMaker: string;
  longTitle: string;
  showImage: boolean;
  permitDownload: boolean;
  webImage?: Image;
  headerImage?: Image;
  productionPlaces: string[];
};

ArtObjectDetails

This interface extends ArtObject with the following addon fields:

interface ArtObjectDetails extends ArtObject {
  priref: string;
  language: Culture;
  copyrightHolder?: string;
  colors: Color[];
  colorsWithNormalization: ColorNormalization[];
  normalizedColors: Color[];
  normalized32Colors: Color[];
  materialsThesaurus: string[];
  techniquesThesaurus: string[];
  productionPlacesThesaurus: string[];
  titles: string[];
  description: string;
  labelText?: string;
  objectTypes: string[];
  objectCollection: string[];
  makers: string[];
}

  audioFileLabel1?: string;
  audioFileLabel2?: string;
  createdOn: string;
  updatedOn: string;
  adlibOverrides: Override;
};
