Using with Node.JS

I faced problem with missed XMLSerializer.

canvas2svg use global defined XMLSerializer. To avoid this problem, you can define globaly XMLSerializer. My snippet with ts, jsdom, c2s

---

import { JSDOM } from 'jsdom';
import { XMLSerializer } from 'xmldom';
const canvas2svg = require('canvas2svg');
///
public asSvg(): string {
    const document = new JSDOM();
    // unnecessery line, but just in case
    document.window.XMLSerializer = XMLSerializer;
    // define globaly window, just in case too :)
    global.window = document.window as any
    // define globaly XMLSerializer
    global.XMLSerializer = XMLSerializer;

     // now you can use c2s without a headache
     const context = new canvas2svg({
         document: document.window.document
    });

    this.buildContext(context);
    return context.getSerializedSvg();
}
