When you ran "npm install express" a copy of the express framework is downloaded from npmjs.com and saved to the folder node_modules/express. When you run require('express') the node.js built-in function require is called. This runs the node module resolution algorithm to find a module named "express", which it ends up finding in the file node_modules/express/index.js.
