Node.js<\/a> is a performant JavaScript backend built off Chrome’s JavaScript engine (v8<\/a>). It’s also wicked fast. Node.js and its accompanying package management, npm<\/a>, are available on newer platforms<\/a> (v6+) without any additional compilation<\/a> from source. Accounts with terminal access<\/a> are eligible to use Node.js and npm.<\/p>\n Newer hosting servers, v6+ and above<\/a>, support running Node.js through Passenger. Passenger automatically manages launching Node.js and scaling the number of Node.js instances\u00a0to meet demand.\u00a0To adapt a\u00a0Node.js script to Passenger, create a compatible<\/a>\u00a0filesystem layout:<\/p>\n Create a .htaccess<\/a> file in Note<\/strong> (v6.5+ platforms<\/a><\/em>): if the system version is insufficient, use nvm<\/a> to specify or install a different Node interpreter.
