Node.js: Which module to “require('..')” to use socket.io？

Question

In https://github.com/socketio/socket.io/blob/master/test/socket.io.js

The code:

What is the module name to require?

Answer 1

它需要父目录中的模块-在本例中为socket.io

Answer 2

A folder can be used as a module if that folder contains, index.js or package.json files etc.

So in this case it is requiring the socket.io.js file in the above folder.

Also if a package.json and index.js file are in the same folder the package.json will get look up priority.
