Problem with Node.JS and jsconfig.json with absolute imports

IDE: Replit
Good afternoon, thanks for checking out.
I wanted to implement absolute imports to my node project, but something odd is happening whenever I try to run the code.
Here are the things I set for my jsconfig.json file:
{
"compilerOptions": {
"baseUrl": "src"
}
}
Now, this is how i'm calling the file I need inside another one:
const {title} = require('util.js')
Oddly, replit's intellisense shows up the right path:
Thumbs Up From Replit
But then, when I finally execute the code, I get this error message:
Error: Cannot find module '/home/runner/Moniqueta-Discordjs/node_modules/util.js/index.js'. Please verify that the package.json has a valid "main" entry

code: 'MODULE_NOT_FOUND',
path: '/home/runner/Moniqueta-Discordjs/node_modules/util.js/package.json',
requestPath: 'util.js'
}
I tried following the error by adding a "valid main entry to my package.json" file, like this:
{
"name": "moniqueta-discordjs",
"version": "1.0.0",
"description": "",
"main": "src/index.js",
"keywords": [],
"author": "sum117",
"license": "ISC",
"dependencies": {
"#replit/database": "^2.0.2",
"discord.js": "^13.8.0",
"src": "^1.1.2",
"util.js": "^0.0.0"
}
}
And when I checked it, it had "util.js" as a declared dependency, I really don't understand what's going on.
Thanks for reading. What am I missing? I really would love this to work...

anchor test command error - Error: Cannot find module '[#project-serum/anchor] ' Please verify that the package.json has a valid "main" entry

I was following an introduction tutorial using anchor (solana framework), it is based in the official github.
In the testing part, I used anchor test command and I got this error:

Try re-installing #project-serum/anchor
yarn add #project-serum/anchor

In your anchor.toml file, try changing the value of 'test' to mocha tests/test.js , replace test.js with whatever the name of your file in tests.

Go check node_modules/#project-serum/anchor if you don't have a "dist" folder there you will have to run yarn add#project-serum/anchor again. When you can see that the "dist" folder was properly installed you'll be able to run your tests again.

protractor import javascript to typescript tests

I have protractor running with typescript and I'm trying to follow the steps on the link
Using require with relative paths
so i can test drag and drop with native javascript from this repo https://gist.github.com/druska/624501b7209a74040175 because there is an issue with Chromedriver and it's not working.
Package.json
"dependencies": {
"#types/jasmine": "^3.5.10",
"#types/node": "^13.11.0",
"dragndrop": "./src/utils/functions/dragndrop/",
"protractor": "^5.4.4",
"typescript": "^3.8.3"
},
Package.json of the module
{
"name": "dragndrop",
"version": "0.1.1",
"description": "Drag and drop object",
"main": "./index.js",
"dependencies": {}
}
This is what I have in my code
var DragAndDrop = require('dragndrop');
var dragAndDropFn = new DragAndDrop();
...
browser.executeScript(dragAndDropFn, elem2, elem1);
When I run the test I get
E/launcher - Error: Error: Cannot find module 'dragndrop'

Can someone tell what do I need to do/change in order to use the javascript module?
Thanks in advance

Electron Cannot find module /resources/app/index.js

I'm new to electron and have made my first electron application, it runs normally running npm start but when using npm run I am unable to execute my application. (I am running ubuntu linux) The cli gives this error message when running the executable file:
A JavaScript error occurred in the main process
Uncaught Exception:

},
"author": "",
"license": "ISC",
"devDependencies": {
"electron-packager": "^8.7.1"
}
}
this is the main.js file :
const electron = require('electron')
const {app, BrowserWindow} = electron
app.on('ready', ()=> {
let win = new BrowserWindow({
width:400,
height:400
})
win.loadURL('http://google.com')
})
Does anyone know what I am doing wrong, thank you for your help.

Ok, that was really stupid. I had named the main js file for the project main.js when in actual fact it had to be named index.js
problem solved!

Node.js "Error: Can not find module"

I am doing the node.js lesson from lynda.com and am unable to find what is causing the "Error: Can not find module". From everything I can tell the package.json has the flight module in it.
Everything has been working so far so I know node.js is installed and running correctly. The way I am running this file is by typing "node app.js" at the command line. Also all of the files are in the same folder.
Here is the console log:
C:\Users\Jonathan\Desktop\flight>node app.js
module.js:340
throw err;
^
Error: Cannot find module './flight'

at Function.Module.runMain (module.js:497:10)
C:\Users\Jonathan\Desktop\flight>
Here is the code.
Package.json file
{
"name": "flight",
"version": "1.0.0",
"description": "a module for keeping track of a flight",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "JBaxter",
"license": "ISC"
}
index.js file
var number, origin, destination;
exports.setNumber = function (num){
number = num;
};
exports.setOrigin = function (o){
origin = o;
};
exports.setDestination = function (d){
destination = d;
};
exports.getInfo = function() {
return {
number: number,
origin: origin,
destination: destination
};
};
app.js file
var flight = require('./flight');
flight.setOrgin('LAX');
flight.setDestination('DCA');
flight.setNumber(462);
console.log(flight.getInfo());
Any help with be great. I thought the name within the package.json file was your module but maybe I am incorrect. Thanks in advance.

"./flight" does not evaluate to index.js in your case.
If you create a subdir :
flight
- index.js
then you can require("./flight") and have it evaluated to "./flight/index.js".
In your case, simplest thing you could to do :
require("./index.js");

you can do it in the following way:
var flight = require('./index.js');
OR
var flight = require('./index');
Following code will not work because the node will look for module named 'flight' in node_modules folder
var flight = require('flight');
