The latest version of Node installed on your machine.To complete this tutorial, you will need the following: In this tutorial, you will install nvm and learn to install, remove, and switch between different versions of Node.js. In those situations, the Node Version Manager (nvm) is a great tool to use, allowing you to install multiple versions of Node.js and switch between them as you see fit. You have the latest and greatest version of Node.js installed, and the project you’re about to work on requires an older version. Once this is setup, you can install Node: # chose desired node version VERSION="8.12.0" # install node nvm install $) app.listen(PORT) console.If you work on multiple Node.js projects, you’ve probably run into this one time or another. ~/.bashrc, ~/.profile, ~/.zshrc, you’ll need to add this: export NVM_DIR=" $HOME/.nvm" & \. We can get the latest stable version of NVM using this process: export NVM_DIR=" $HOME/.nvm" & ( git clone " $NVM_DIR" cd " $NVM_DIR" git checkout `git describe -abbrev=0 -tags -match "v*" $( git rev-list -tags -max-count=1)` ) & \. This guide demonstrates how to do install and use NVM ( Node Version M anager) to accomplish this on Linux, macOS, and Windows. For this reason, you need a way to not only install Node.js easily, but also switch between Node.js versions. There’s one slight problem, the Node.js platform and community of tools and libraries are fast moving targets, and what might work under one Node.js version will not be guaranteed to work for another version of Node.js.
It’s used for traditional web sites and back-end API services, but was designed with real-time, push-based architectures in mind. js is primarily used for non-blocking, event-driven servers, due to its single-threaded nature.
There are many reasons, including the ability to transfer JavaScript platform knowledge around frontend programming to backend programming, and the platform itself: These days in web applications, Node.js platform is ubiquitous.įor frontend tooling, the npm (node package manager) part of Node.js tool set will likely be part of that your frontend tool set.įor backend services, to say that Node.js is extremely popular would be an understatement.
