Function createDoclingLoader

Checks whether python3 -m docling is available in the current environment and, if so, returns a new Docling-backed loader instance; otherwise returns null.

The availability check runs python3 -m docling --version synchronously via spawnSync — it exits quickly and is only called once during registry initialisation.

Usage

import { createDoclingLoader } from './DoclingLoader.js';
import { PdfLoader } from './PdfLoader.js';

const doclingLoader = createDoclingLoader();
const loader = new PdfLoader(null, doclingLoader);
