module.exports that include all functions in a single line

Question

This is a follow-up question to In Node.js, how do I "include" functions from my other files?

I would like to include an external js file that contains common

Answer 1

It is worth noting that in ES6, you can now export functions like this:

export function foo(){}
export function bar(){}
function zemba(){}

Simply write export before the functions you want to export. More information here.

Answer 2

A really old question but I just had to solve the same issue myself. the solution I used was to define a Class inside the module to contain all my functions and simply export an instance of the class.

classes.js looks like this:

class TestClass
{
   Function1() {
        return "Function1";
    } 
    Function2() {
        return "Function2";
    }
}

module.exports = new TestClass();

app.js looks like this:

const TestClass = require("./classes");
console.log( TestClass.Function1);

just keep adding more functions to the class and they will be exported :)

Answer 3

I have done something like the following:

var Exported = {
   someFunction: function() { },
   anotherFunction: function() { },
}

module.exports = Exported;

I require it in another file and I can access those functions

var Export = require('path/to/Exported');
Export.someFunction();

This is essentially just an object with functions in it, and then you export the object.

Answer 4

You can write all your function declarations first and then export them in an object:

function bar() {
   //bar
}

function foo() {
   //foo
}

module.exports = {
    foo: foo,
    bar: bar
};

There's no magical one-liner though, you need to explicitly export the functions you want to be public.

Answer 5

If you use ES6 you can do something like that:

function bar() {
   //bar
}

function foo() {
   //foo
}

export default { bar, foo };

const fs = require("fs")


var ExportAll = {

    deleteFile : function deleteFile(image,folder="uploads"){
    
        let imagePath = `public/${folder}/${image}`
    
        if (fs.existsSync(imagePath)){
            fs.unlinkSync(imagePath)
        }
    },


    checkFile : function checkFile(image,folder="uploads"){
    
        let imagePath = `public/${folder}/${image}`
    
        if (fs.existsSync(imagePath)){
            return true
        }
        else{
            return false
        }
    },
    

    rand : function(min=1,max=10) 
           {
        return Math.floor((Math.random() * max) + min)
          }
}

module.exports = ExportAll
