You can access the main module that node started with require.main from
every module running in the same process, i.e both main module itself and
all imported modules.
main.js:
module.touchable = "ouch!";
mdl = require('./module.js');
mdl.try_touching();
module.js:
module.exports.try_touching = function () {
console.log(require.main.touchable);
}
Be careful that require.main is the module object, not module's globals.
So, instead of var var_name='var_value', we used module.var_name='var_value'.
In addition to this, instead of attaching your variables directly to module
object itself like I did in the example above, it is better practice to use
module.exports for reasons like consistency, niceness, and also preventing
namespace pollution.
