You’ll have to close and re-open the terminal first, but you can verify a successful installation by using command -v nvm. To update to the latest version of nvm, you can get the install script by using cURL: curl -o- | bash Run an update of nvm first, then get the latest packages of Node.js to update your web server environment: sudo apt-get update sudo apt-get install build-essential checkinstall libssl-dev You’ll need a C++ compiler, as well as the build-essential, and the libssl-dev packages. Node Version Manager, or nvm, is far and away the best method for updating Node.js.
Update Node.js Using Node Version Manager (nvm)
This guide also includes instructions for updating Node.js through binary packages with version-specific references. If extenuating circumstances prevent you from using nvm, you can rely on the resources of Node Package Manager (npm). We value simplicity and effectiveness in systems administration and, for us, the easiest method is to use Node Version Manager (nvm).īefore you start, check which version of Node.js you’re currently using by running node -v in a command line terminal. I will show you how to install build tools here.The exact steps to updating Node.js on a Linux system can vary by distribution, but our recommended methods will work across most versions. The NodeJS native addons needs a C++ build tool installed on your computer as the modules are built while you install them using Node Package Manager. NodeJS codes runs almost as fast as C and C++ compiled code if the NodeJS module that you’re using is written using the Native Addons NodeJS API. So NodeJS adds an additional layer to compile JavaScript code to native binary code. How that work is, NodeJS relies on Chrome V8 JavaScript engine, which is written in C++. To solve this problem, NodeJS has native addons. At times that has performance issues as JavaScript is not as fast as a compiled language such as C and C++. Installing Build Tools for Native Addons:Īll the NodeJS modules are written in JavaScript. NodeJS is basically JavaScript on the server.In this article, I will show you how to install and configure NodeJS on CentOS 7. JavaScript can be used just like any other interpreted programming languages such as Python, Ruby etc. But a web browser is not the only place JavaScript is used these days. It is mainly used in Web browser to make your website interactive. JavaScript is the programming language of the Web.
