We can say that npm is a package manager for Node.js with hundreds of thousands of packages.
Although it does create some of your directory structure/organization, this is not the main purpose. The main goal, as you touched upon, is the automated dependency and package management.
Whenever you work with npm/node you can see it manages a file called package.json in which it stores all the dependency you have used in your project under the dependency section. Which means you can specify your project’s dependencies in the package.json file and any time you or anyone else needs to get started with your project they can just need to run npm install which will install all the dependencies in the node_module directory. On top of this, it is also possible to specify what versions your project depends upon to prevent updates from breaking your project.
It is definitely possible to manually download your libraries, copy them into the correct directories, and use them that way. However, as your project and list of dependencies grows, this will quickly become time-consuming and messy. It also makes collaboration and sharing more difficult. So to make our life easy let’s start installing npm.
