Am I installing modules correctly via NPM?

Question

npm

I'm trying to install the Socket.io module in my project folder, but after executing the command
npm install socket.io --save, about 80 modules appear in the node_modules folder.
Is this how it should be or can I remove everything except the desired module?
And one more question: there is also node_modules in the Node.js folder, but only npm is there.
Maybe modules need to be put in it?

That's right, don't delete anything. Each module can have dependencies, which can have their own dependencies, and so on. Therefore, usually when installing one module, several are installed.

Global modules are placed there - those that are used not in a specific project, but in general on your computer.
