Installing Packages Locally and Globally

Installing Locally:

To install a package locally, meaning it is specific to your current project, use the following command:

npm install <package-name>

Example:

npm install lodash

This installs the "lodash" package and adds it to your project's node_modules folder.

Installing Globally:

To install a package globally, making it available across your entire system, use the -g flag:

npm install -g <package-name>

Example:

npm install -g nodemon

This installs "nodemon" globally, allowing you to use it as a command-line tool.

Updating and Uninstalling Packages

Updating Packages:

To update a package to its latest version, use the following command:

npm update <package-name>

Example:

npm update lodash

This updates the "lodash" package to its latest version.

Uninstalling Packages:

To uninstall a package, removing it from your project or system, use the following command:

npm uninstall <package-name>

Example:

npm uninstall nodemon

This removes the globally installed "nodemon" package.

Uninstalling Globally:

To uninstall a globally installed package, use the -g flag:

npm uninstall -g <package-name>

Example:

npm uninstall -g nodemon

This removes the globally installed "nodemon" package.

These basic npm commands empower developers to manage packages effectively, whether they're working on a specific project or making tools available system-wide. Understanding these commands is fundamental for a smooth development experience and maintaining up-to-date and well-organized projects.
