"npm install saxon-js" not generating .d.ts file

Question

Following command failing with 404 error.

npm i --save-dev @types/saxon-js 

I am trying to convert xml using stylesheet from a nodejs typescript project. Can anyone help me here to get rid of the following error?

npm ERR! 404 Not Found - GET https://registry.npmjs.org/@types%2fsaxon-js - Not found

Generally --save-dev works for all packages, but this one is not working.

npm i --save-dev @types/saxon-js

Seemingly, there are no type definitions available. I am also currently trying to find the source for those type definitions. However, I found them earlier but can't remember where I found them. So, here you go:

declare module "saxon-js" {
  /**
   * Exactly one of stylesheetLocation, stylesheetFileName, stylesheetText, or stylesheetInternal must be supplied.
   * Exactly one of sourceLocation, sourceFileName, sourceNode, or sourceText can be supplied.
   */
  export interface ITransformOptions {
    /**
     * A URI that can be used to locate the compiled stylesheet (a SEF file in JSON format).
     */
    stylesheetLocation?: string;

    /**
     * A file name that can be used to locate the compiled stylesheet (a JSON document).
     * Available in Node.js only. The filename, if relative, is resolved against the
     * current working directory.
     */
    stylesheetFileName?: string;

    /**
     * The JSON text content of the compiled stylesheet.
     */
    stylesheetText?: string;

    /**
     * This may be set to the JavaScript object that results from JSON-parsing of the SEF file.
     */
    stylesheetInternal?: object;

    /**
     * The static base URI of the stylesheet, as an absolute base URI.
     * Used, for example, by functions such as doc() or resolve-uri().
     */
    stylesheetBaseURI?: string;

    /**
     * Either "json" or "xml": used with sourceLocation, sourceFileName, or sourceText
     * to indicate whether the source is JSON or XML. Defaults to "xml".
     */
    sourceType?: string;

    /**
     * URI that can be used to locate the XML or JSON document.
     */
    sourceLocation?: string;

    /**
     * File name of the XML or JSON document. Available in Node.js only.
     * The filename, if relative, is resolved against the current working directory.
     */
    sourceFileName?: string;

    /**
     * The principal input as a DOM Node. This will normally be a Document or
     * DocumentFragment node, but any node is acceptable. (If it is not a
     * Document or DocumentFragment, then it will not match any match="/"
     * template rule.)
     */
    sourceNode?: Node;

    /**
     * Lexical XML or JSON supplying the source document.
     */
    sourceText?: string;

    /**
     * Absolute base URI for the source. The base URI of the source is automatically

     */
    sourceBaseURI?: string;

    /**
     * Determines what happens to the principal result tree from the transformation.
     * The default value is "application".
     */
    destination?:

     */
    resultForm?: "default" | "array" | "iterator" | "xdm";

    /**

    baseOutputURI?: string;

  export interface ITransformOutput {
    principalResult: any;
    resultDocuments: object;
    stylesheetInternal: object;
    masterDocument: Node;

  export function transform(
    options: ITransformOptions,
