Installing Node.js via Package Manager

Installating Node.js via Package Manager

Ref: Node.js - Installing Node.js via package manager

$ sudo apt install nodejs npm

Update npm to latest version:

$ sudo npm install -g npm

Verifing Node.js and npm (Node Package Manager):

$ node -v
$ npm -v

Installing Node.js using Setup Script

Ref: https://github.com/nodesource/distributions/blob/master/README.md#debinstall

For Ubuntu 18.04 and higher:

$ curl -fsSL https://deb.nodesource.com/setup_<version>.x | sudo -E bash -

which should be: current or 17, lts or 16, 14, 12.

$ sudo apt install -y nodejs

Install build tools (Optional):

$ sudo apt install -y build-essential

Verifing NodeJS:

$ which node
$ node -v

Updating NodeJS with with NPM (Node Package Manager)

First, clear the npm cache:

$ npm cache clean -f

Install n, Node’s version manager:

$ npm install -g n

With the n module installed, you can use it to:

Install the latest stable version:

$ sudo n stable

Install the latest release:

$ sudo n latest

Install a specific version:

$ sudo n [version.number]

Update Node.js with Binary Packages

Navigate to Node’s official downloads page where you can find all available packages. There you can download the source code or pre-built installer for the LTS versions or the latest release.
You can either download the package from your browser or find the version number you need and add it to the wget command:

wget https://nodejs.org/dist/v14.17.0/node-v14.17.0-linux-x64.tar.xz

Next, install xz-utils used to extract the binary package:

$ sudo apt-get install xz-utils 4. Extract and install the package with the command:

$ sudo tar -C /usr/local --strip-components 1 -xJf node-v14.17.0-linux-x64.tar.xz

Installing NodeJS via NVM (Node Version Manager)

Install NVM

Check latest version:

https://github.com/nvm-sh/nvm/releases/latest

Install using script:

$ NVM_VERSION=v0.39.7
$ wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/${NVM_VERSION}/install.sh | bash

Source the profile:

$ source ~/.bashrc

Verify Installation:

$ command -v nvm
$ nvm --version

(Optional) Deeper Shell Integration

Create .nvmrc in project directory:

To make nvm default to the latest 5.9 release, the latest LTS version, or the latest node version for the current directory:

$ cd /path/to/project
$ echo "5.9" > .nvmrc
$ echo "lts/*" > .nvmrc # to default to the latest LTS version
$ echo "node" > .nvmrc # to default to the latest version

Then when you run nvm:

$ nvm use

Found '/path/to/project/.nvmrc' with version <5.9>
Now using node v5.9.1 (npm v3.7.3)

To automatically call nvm use in a directory with a .nvmrc file, put the following at the end of your $HOME/.bashrc:

$ nano ~/.bashrc

cdnvm() {
    command cd "$@" || return $?
    nvm_path="$(nvm_find_up .nvmrc | command tr -d '
')"

    # If there are no .nvmrc file, use the default nvm version
    if [[ ! $nvm_path = *[^[:space:]]* ]]; then

        declare default_version
        default_version="$(nvm version default)"

        # If there is no default version, set it to `node`
        # This will use the latest version on your machine
        if [ $default_version = 'N/A' ]; then
            nvm alias default node
            default_version=$(nvm version default)
        fi

        # If the current version is not the default version, set it to use the default version
        if [ "$(nvm current)" != "${default_version}" ]; then
            nvm use default
        fi
    elif [[ -s "${nvm_path}/.nvmrc" && -r "${nvm_path}/.nvmrc" ]]; then
        declare nvm_version
        nvm_version=$(<"${nvm_path}"/.nvmrc)

        declare locally_resolved_nvm_version
        # `nvm ls` will check all locally-available versions
        # If there are multiple matching versions, take the latest one
        # Remove the `->` and `*` characters and spaces
        # `locally_resolved_nvm_version` will be `N/A` if no local versions are found
        locally_resolved_nvm_version=$(nvm ls --no-colors "${nvm_version}" | command tail -1 | command tr -d '\->*' | command tr -d '[:space:]')

        # If it is not already installed, install it
        # `nvm install` will implicitly use the newly-installed version
        if [ "${locally_resolved_nvm_version}" = 'N/A' ]; then
            nvm install "${nvm_version}";
        elif [ "$(nvm current)" != "${locally_resolved_nvm_version}" ]; then
            nvm use "${nvm_version}";
        fi
    fi
}

alias cd='cdnvm'
cdnvm "$PWD" || exit

Source bash profile changes:

$ source ~/.bashrc

(Optional) Bash Completion

Put the below sourcing line just below the sourcing line for nvm in profile (.bashrc or .bash_profile).

$ nano ~/.bashrc

#! ~/.bashrc
[[ -r $NVM_DIR/bash_completion ]] && \. $NVM_DIR/bash_completion

$ source ~/.bashrc

Usage

nvm:

$ nvm Tab

Install NodeJS

<node_version> can be one of (17, 16, 14, 12).

To install latest version of Node:

$ nvm install node

To install specific version of Node:

$ nvm install <node_version>;

To see all versions of Node that are installed on local machine:

$ nvm ls

To switch to specific version:

$ nvm use <node_version>

To set default specific version:

$ nvm alias default <node_version>

Update NodeJS

Before upgrading Node.js, check which version is running on the system:

$ nvm ls

Check for newly available releases with:

$ nvm ls-remote

To update the latest version, use the nvm command with the specific Node.js version:

$ nvm install [version.number]

E.g: $ nvm install 14 (or) $ nvm install 14.x.x

Uninstall NodeJS

To uninstall latest version of Node use command:

$ nvm uninstall node

To uninstall specific version of Node (for example - 14):

$ nvm uninstall 14

Packages location:

~/.nvm/versions/node//lib/node_modules

UnInstall NPM

Remove any nvm lines from ~/.bash_profile , ~/.bashrc(and/or ~/.profile) and re-source the bash profile:

$ nano ~/.bashrc
...
$ source ~/.bashrc

Remove all directories previously created:

$ rm -rf ~/.nvm
$ rm -rf ~/.npm
$ rm -rf ~/.bower

NodeJS Usage

Use with -g if install/update package globally.

Update npm (NodeJS Package Manager):

$ npm i -g npm

Install/Update yarn:
