In which path should I install socket.io for node.js programming

In which path should I install socket.io for node.js programming. should I install it in the same path as that of node.js ?

Your best approach is to use npm to install your packages:

npm install socket.io

This will install it in the folder where you run it for that specific project.

If you want it to be installed globally for all your projects:

npm install -g socket.io
