Introduction to installing Node with NVM

In the world of web development, JavaScript is one of the most popular programming languages. And if you are interested in working with JavaScript, you will surely need to install Node.js on your machine. But how can you do it in the most efficient way?

Installing Node with NVM

To install Node.js easily and without compatibility problems, I recommend using NVM (Node Version Manager). NVM is a tool that allows you to manage multiple versions of Node.js on your system. This is especially useful if you need to work on projects that require specific versions of Node.js.

To get started, you can download and install NVM by following the instructions in the official NVM documentation. Once you've installed NVM, you're ready to install Node.js.

Installing Node.js with NVM

The Node.js installation process with NVM is very simple. Here I show you the steps to follow:

1. Open your terminal and run the following command to list the Node.js versions available for installation:

nvm ls-remote

1. Select the version of Node.js you want to install and run the following command:

nvm install desired_version

For example, if you want to install version 14.17.0 of Node.js, you would run:

nvm install 14.17.0

1. Once the installation is complete, you can verify that Node.js has been installed correctly by running the following command:

node -v

And that's it, you have successfully installed Node.js using NVM!

npm: Package management in Node.js

Once you have Node.js installed, you will also have access to npm (Node Package Manager). npm is the most widely used JavaScript package manager and allows you to install, share, and manage dependencies for your Node.js projects.

You can use npm to install popular libraries and frameworks, such as Express.js, React.js, Angular.js, and many others. Additionally, npm allows you to keep your dependencies up to date and easily update them to new versions.

To use npm, simply run the following command in your terminal:

npm command

For example, to install a specific dependency, you can run:

npm install package

Remember that you can find more information about the commands and options available in the official npm documentation.
