NodeJS module structure for multiple .js files with functions

ATM I have a folder in my NodeJS application where I store my JS files with a couple of functions. I require these files in my main.js at the top an use them as usual.

my-app/
├── node_modules/
├── my_jsfiles/
│   ├── functions_1.js
│   └── functions_2.js
├── package.json
└── main.js

main.js:

const myFuncs1 = require('./my_jsfiles/functions_1.js')
const myFuncs2 = require('./my_jsfiles/functions_2.js')

myFuncs1.someFuncsInside()
myFuncs2.someFuncsInside()

APPROACH: Now that I am going to use my_jsfiles in more applications I would like to make my own NodeJS module, which works so far, but I stuck at the point how I can include multiple js files instead of just calling functions from the index.js

my-app/
├── node_modules/
│   ├── my-jsfunctions/
│   │   ├── index.js
│   │   ├── functions_1.js
│   │   └── functions_2.js
├── package.json
└── main.js

main.js:

const myFuncs = require('my-jsfunctions')
//How do I call functions from functions_1.js and functions_2.js?

I know that I can export functions from the index.js

exports.someFunction = function () {
    console.log("This is a message from the index.js");
}

But what is the propper way to call functions from the other files, because I do not want to have just one index.js file with million lines of code.

Solution 1:

you just need to import all your functions into index.js file and export from there

my-app/
├── node_modules/
├── my_jsfiles/
│   ├── functions_1.js
│   └── functions_2.js
├── package.json
└── main.js

function_1.js

function functions_1_1(){
}
module.exports={functions_1_1}

function_2.js

function functions_2_1(){
}
module.exports={functions_2_1}

index.js

const {functions_1_1} = require("./function_1.js");
const {functions_2_1} = require("./function_2.js");
module.exports={functions_1_1,functions_2_1}

main.js

const {functions_1_1,functions_2_1} =require("./my_jsfiles/index.js");
functions_1_1()
functions_2_1()

Solution 2:

you should just be able to do

const myFuncs1 = require('my_jsfiles/functions_1.js')
const myFuncs2 = require('my_jsfiles/functions_2.js')

isn't it working?
