FOR THE QUESTION YOU HAVE ASKED, IN MY OPINION, THE ANSWERS GIVEN WITH OPEN SOURCE E COMMERCE SOLUTIONS LIKE MAGENTO, OPENCART, WOOCOMMERCE, VIRTUEMART ARE NOT RELEVANT. BECAUSE, THESE E COMMERCE SOLUTIONS ARE MORE THAN 10 YEARS OLD.
Next, I'm not sure if I have to answer your questions stating the newest eCommerce solutions in the market or the solutions built on the latest technologies. However, I strongly believe that technologies matter too and today, although 80 percent of the websites' backend is built on PHP, the recent and futuristic NodeJS technology is seeing a popularity among modern Developers.
So, I would like to answer your question on two lines - first, based on the recent entry into the market and not older ones like OpenCart or Magento that exists for more than last 12 years. And second, based on the technology on which these new entries have been built on. Because, I strongly think that technology that matter a lot.
Now, coming to NodeJS, although as already mentioned, PHP has been popular for over years, NodeJS is now being adored by many Developers because, of its scalability and performance. Using NodeJS, an eCommerce website can be built not only at low cost, but a result of high performing, fast and speedy application can be seen.
