Node.js - What's the scope of the require()d modules?

If I understand your question correctly, you have theses files:

.|_. app.js|_. routes/  |_. user.js  |_. department.js  |_. services/    |_. user

And your code do this:

app.js call user.js    user.js call userapp.js call department.js    department.js

In that case, at the first time user is required, it is put on cache in require.cache.

Then the second time it is called, the caller get require.cache['./service/user'], where is stored your object.

As such, you do have the same object in both department.js and user.js.
