While these programs have some slight differences, the basic commands for installing, listing and switching between Node.js versions are identical except for where noted. NVM was originally designed for Linux and OS X, but there is a similar program called NVM Windows. You can install each version with a single command and set a default via the command line interface. Node Version Manager is a tool that allows programmers to seamlessly switch between different versions of Node. The Technical Steering Committee of the Node.js Foundation oversees LTS release policies and strategies while the LTS Working Group actually manages support. Maintenance releases periodically receive critical fixes and documentation updates. Meanwhile, active versions get non-breaking backports of any changes implemented in the most current version a few weeks after release. Versions under LTS receive active support for 18 months followed by an additional 12 months of maintenance support.

Whenever a new odd-numbered version comes out, the most recent even version goes to long-term support, or LTS. Node.js version updatesĪ new release of Node.js is cut from the GitHub master branch every six months around April and October. In, Node.js, commands are executed in parallel, and callbacks are used to determine completion or failure. In PHP, functions tend to block until completion, which means that commands execute one at a time.

Node.js is similar to PHP, but there are some notable differences. They can be written with any language that can compile to JavaScript such as CoffeeScript, Dart and TypeScript. Node.js applications run on Linux, macOS, Windows, NonStop and Unix servers. Its core functionality is supported by modules based on an API intentionally designed to make writing server applications less complex. Node.js is an open source JavaScript run-time environment used for making web servers and other networking tools. This guide covers all of the commands you need to know to start switching Node versions with no hassle.

Fortunately, there is an easy way to install and manage them all from a single machine thanks to Node Version Manager.

If you build Node.js applications, you may want to use different versions of Node.
