error while running with webpack bundle in nodejs

Getting following error while trying to run turndown. I am using esbuild to get the bundle for same.

/Users/mohitsingh/Documents/abc/dom-text-abc-function/dist/main.js:21918
        } else if (stack.top instanceof impl.HTMLTemplateElement) {
                             ^

Its due to this fgnass/domino#146

[mohit-singh-pepper]

Is there a workaround, anyone know of ?

[martincizek]

Not familiar with webpack, so the workaround in general terms:

1. use the browser build as the dependency - the browser build does not contain domino (see package.js)
2. if your build is for a browser, you're done. If it is for an environment without DOM parser, you need to bring your own DOM parser (e.g. jsdom) and call turndown with a DOM object instead of string.

For reference, discussion about separating turndown and the DOM implementation: #265 .

@mohit-singh-pepper did you found a solution ?

[baltagih2]

For anyone still running into this problem, the following worked for me (based on the commit from @julienc91 above):

npm i jsdom
npm i --save-dev @types/jsdom

import { JSDOM } from "jsdom";
import TurndownService from "turndown";

const turndownService = new TurndownService();


const result = turndownService.turndown(
      JSDOM.fragment(your_html_content)
    );
