Solution

There is no official documentation, but take a close look at source code, you will find the answer.

source

Module.prototype._compile = function(content, filename) {
    ...
    var args = [self.exports, require, self, filename, dirname];
    return compiledWrapper.apply(self.exports, args);
};

while module._compile in invoke by NativeModule source
