It is asynchronous and event-driven – All NodeJS APIs are asynchronous.NodeJS is Non blocking in nature – It executes the next tasks in the stack while waiting for a response on previous.NodeJS is a single threaded language – It uses multiple threads to execute asynchronous code.In this article we shall cover installation of Node.js 18 LTS CentOS 8|RHEL 8|Rocky Linux 8. NodeJS is built on Chrome’s V8 JavaScript engine and it provides a cross-platform, non-blocking (asynchronous), event driven runtime environment for Developers to build highly scalable server-side applications using JavaScript. JavaScript being the developers first choice to develop new web applications make NodeJS robust framework in creation of server side web applications. Node.js is a popular programming language mainly because it uses the JavaScript as the main application to create new application. If you want to test your Node.js installation, create a web server and run with Node.js.We all know JavaScript as a language to write once and run anywhere. firewall-cmd -permanent -add-port=8080/tcpįirewall-cmd -reload Create Test Web Server So, to access the application, we need to allow TCP port 8080 in the firewall. In the next section, we will create a web server that will listen on TCP port 8080 to validate the NodeJS application.

To install the Yarn package manager, run: curl -sL -o /etc//yarn.repo Yarn is another package manager to install and manage packages for Node.js. yum install -y nodejsĬheck the version of Node.js using the following command. NPM (Node Package Manager) will also be installed along with Node.js.

Once after adding the PPA on the server, install the Node.js by using the following command. Node.js 12.x (LTS) yum -y install -y curlĬurl -sL | bash - Node.js 13.x (Latest Version) yum -y install -y curl You can choose either one of the Node.js version to install on your machine. NodeSource maintains Node.js binary packages for CentOS, Ubuntu and Debian operating systems. yum groupinstall -y 'Development Tools' Configure Node.js Repository You may need to install build tools if you want to compile and install native addons from npm. Check out the official page to get the latest version of Node.js. There are two versions of Node.js is available for the users. CentOS 8 Debian 10/9 Ubuntu 18.04 Ubuntu 16.04 Node.js Versions
