    }

    Bas.Sonraki = EklenecekKullaniciAdi;

    this.Uzunluk++;

    return EklenecekKullaniciAdi;
};

Answer 1

First you have to declare inside of your KullaniciLibrary.js file, what you want to export. you do this by adding following line at the end of the file:

module.exports = YOUREXPORT;

YOUREXPORT will probably just be the methodname (or some object). After that, you wanna import it like this:

var KullaniciJS = require('./KullaniciLibrary');

Note that you have to prefix the name with ./ and you don't need to define the file-ending.

If you don't prefix the module with ./ , node will search for the module in the node_modules folder, instead of the current directory

Answer 2

In nodejs to require a function from another file you have to export then function. To export the function use:

module.export='your function name';

and to require the function use:

const variable=require(./filename)
