As JavaScript became one of the most popular programming languages, more and more customers demand Node.js hosting. With our unique Node.js Selector, you are now able to host your JavaScript apps using Node.js 6, 8 or 9. Node.js is introduced with a friendly UI that unites all of the features in one place and makes it very convenient to manage.

Note that Node.js Selector icon in end user interface is absent when Node.js is disabled via the Feature Manager in WHM. If you are not a reseller, and for some reason cannot access this please raise a support ticket.
