LDkit

Registers a data type handler for translating between RDF literals and JavaScript values.

In order to register a custom data type handler, the custom data type TypeScript mapping needs to be added to the CustomDataTypes interface using module augmentation.

Two handlers are required:

1. A function to translate from RDF literal value (string) to JavaScript value.
2. A function to translate from JavaScript value to RDF literal value (string).

import { registerDataHandler } from "ldkit";

const customNumberDataType = "http://example.org/number";

declare module "ldkit" {
  interface CustomDataTypes {
    [customNumberDataType]: number;
  }
}

registerDataHandler(
  customNumberDataType,
  (literalValue: string) => parseInt(literalValue),
  (nativeValue: number) => nativeValue.toString(),
);
