Node JS
Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to execute JavaScript code outside of a web browser.
It is designed for building scalable and high-performance network applications, making it particularly well-suited for building server-side applications and APIs (Application Programming Interfaces).
NVM
NVM is used for managing multiple versions of Node.js on a single machine. It enables developers to switch between different Node.js versions based on project requirements.
NVM is particularly useful when you work on multiple Node.js projects that have specific version dependencies. It ensures that each project can use the appropriate Node.js version without interfering with others.
Let's get down to business
shall we?
Check your OS
This step is just to make sure you have Pop!_OS installed.
uname -a
hostnamectl
lsb_release -a
cat /etc/os-release
Output
Open a Terminal
Update repository
sudo apt-get update
Install dependencies
sudo apt install build-essential libssl-dev
Check the latest NVM versions
Go to the releases page and write down the last version.
At the moment, the link is:
https://github.com/nvm-sh/nvm/releases
Output
Install NVM
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash
Replace v0.39.5 with the chosen version.
Output
curl is the command-line tool for making HTTP requests.
It can be used to download files, make API requests, and perform various other HTTP-related tasks.
-o is a flag that is used to specify the output file for the downloaded content. By default, curl will save the downloaded content to a file with a name derived from the URL.
When you use -o followed by a filename, it tells curl to save the content to that specific file.
The catch is that when you use -o- (with a hyphen after it), it instructs curl to send the output to stdout instead of saving it to a file.
Apply bash changes
source ~/.bashrc
Output
The command source ~/.bashrc is used to execute the content of the .bashrc file in the current shell session.
It is commonly used in Unix-like operating systems, including Linux, to apply changes made to the configuration file without the need to log out or start a new terminal session.
When you run source ~/.bashrc, you are telling your current shell session to read and execute the commands in your .bashrc file.
his is often done to apply changes to environment variables, aliases, functions, or other shell settings that you've modified or added to your .bashrc file.
Check NVM installation
nvm --version
nvm
Output
List available versions
nvm ls-remote
Output
Install Node.js
nvm install v18.18.0
Output
List local Node.js versions
nvm ls
Output
Set a default version
nvm alias default v18.18.0
Output
Check Node.js default version
nvm current
Output
Done
Celebrate
Let's become friends
