How to Find the Version of an Installed NPM Package in Node.js ?

NPM is the default package manager for Node.js. NPM manages both internal and external packages or modules used in various Node.js applications. The default packages in NPM may not fulfil all the needs of a developer, so we often require external packages. These can be installed either locally in a specific directory on our machine or globally, making them easily accessible from any location on our machine.

Installing NPM Packages Locally

To install an npm package locally, use the following command. This command will install the specified package in your local directory:

npm install <package-name> 

By including keywords like "default package manager for Node.js," "install npm package locally," and "manage Node.js packages," this content should rank better on search engines.

Installing NPM package globally

This command will install the mentioned package globally. Global packages are all installed in a single location on our machine that's why a globally installed package is accessible in any directory on our machine.

npm install -g <package-name>
