JS course recommendation? Check out The complete Node Developer course by Rob Percival - see others As I mentioned above, picking a Node version is not that of a big deal and you can always upgrade or downgrade versions when needed.
If you are learning Node JS by following a tutorial, you can always check the version the instructor has used. You will be safe using a version that is higher than the version used by the instructor. Now that you know which version to pick when working with Node JS, let me tell you a bit more about the Node version lifecycle. Nodejs org makes new versions frequently with new features, bug fixes, and performance optimizations.
As a general rule, we can safely assume that the latest version is always the best version to use. A major node version increments the first number like this: 6.
You will notice that in the Node download page you will find two versions, one marked as LTS and the other marked as Current. Instinctively you would want to download and start using the current version of the software. However, this version is not intended for you the general user but for the library authors.
Node JS has many uses. Various tools that make it easy to compile code such as Webpack, Gulp, Browserify, and others heavily rely on Node JS. With a new major release of Node, it will allow these library owners 6 month time to download and make their tools compatible with new features and updates. So in a nutshell, the current odd number Node JS versions such as After 6 months, the odd number versions become unsupported, so there is no point in using these versions for development.
After the first 6 months have passed and library vendors have enough time to test and implement new features into their tools, the even number versions 8. By the time you get access to an LTS version, you can rest assured that all of your favorite NPM tools are tested and supported by this version of Node. So if you are building a production application, you will get support for it for the next two years and more. The LTS version guarantees that the software will be maintained and critical bugs will be fixed during this period of time.
This all means that if today you start learning with Node JS 12, you are good to deploy a production app within with the same version. You can downgrade the node version by specifying a version in the related commands. You can use the nvm install command to install a specifc version: nvm install[version. For installing npm, please refer to the Node. If you need npm for building mobile apps, the easiest way to run npm commands in the app build workflows is to use Appcircle which handles all the installation and maintenance steps automatically.
Even though npm comes with Node. For this reason, upgrading npm is an independent task. There may be cases where you only update npm, but keep Node. Also note that npm-upgrade and npm-update are related with npm packages, so they are not directly related with upgrading the npm itself. Before any operation, you can check the npm version by using the npm -v command in the terminal.

You can downgrade the npm version by specifying a version in the related commands. To upgrade npm to the latest version on macOS or Linux, you can use the following command: npm install -g [email protected].
If you want to downgrade npm to a specific version, you can use the following command: npm install -g [email protected] [version. Yarn requires the presence of Node. Every operating system has different ways to install Yarn. If you need Yarn for building mobile apps, the easiest way to run Yarn commands in the app build workflows is to use Appcircle which handles all the installation and maintenance steps automatically.
To install Yarn on macOS, you can use the Homebrew package manager with the command brew install yarn or you can run the following official install script:. Before any operation, you can check the Yarn version by using the yarn --version command in the terminal.

The common way is to use the and yarn set version command. You can download the latest release with yarn set version latest or you can use yarn set version [version.
The aim of NPM is automated dependency and package management, anytime or anyone needs to get started with the project they can simply rum NPM install and all the dependencies they will have immediately.
