Node.js | 从导入文件中的原始文件调用函数

Question

I recently tried to organize my code by exporting functions into different files, so my main file stays clean. To do so I imported the other js file in my main file with
const request = require('./request.js');
In "request.js" I used export , so I can call the function in my main file. Is it is possible to call a function, that is defined in the main file, from the "request.js" file? Unfortunately I can't just return the information back to the main file, because I am using callbacks.

Yes it's possible.

You just need to export function from the main file and then import your main file inside request.js :

// main.js:

module.exports.someFunction = function() {
    // Some code
};

const request = require('./request.js');
request.someRequestFunction();

// request.js

var main = require('./main.js');

module.exports = {
    someRequestFunction: function() {
        main.someFunction(); // Call function from main module
    }
};
