The two primary package managers for Node.js applications, including for JavaScript/TypeScript are NPM and Yarn. Additions to the Plug 'n' Play strategy have yielded current state-of-the-art package managers

• PNPM: An stand-in NPM replacement (my personal favourite).
• Yarn 2 (with Plug 'n' Play): The second generation of the awesome Yarn package manager.

Using (P)NPM ​

Note that I will be using the npm but pnpm can be used as a direct replacement for this command. Many people set the alias npm=pnpm To install Node Package Manager (NPM) on Ubuntu/Debian use

sudo apt install npm nodejs

sudo apt install npm nodejs

To change versions, install Node Version Manager (NVM) with the following install script

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

Then change version with

nvm install 14
nvm use 14
nvm -v

nvm install 14
nvm use 14
nvm -v

Using Yarn ​

Install Yarn through NPM.

npm install --global yarn

npm install --global yarn
