There is no simple answer to this question. It depends on many factors, such as the specific requirements of your eCommerce website, the features you need, the scalability you need, etc.
Node.js is a great choice for eCommerce websites that are heavy on server-side processing. If your website needs to handle a lot of requests at once, Node.js will be able to do so more efficiently than other languages.
However, Node.js is not the best choice for every eCommerce website. If your website does not need to do a lot of server-side processing, or if you need your website to be compatible with older browsers, then you may want to choose a different language.
The best way to decide if Node.js is the right choice for your eCommerce website is to consult with a development team that has experience with Node.js and eCommerce website development.
