getting a import statement error in node js

I started learning node.js recently.
I was using vs code and going through url module and got this error.
PS G:\node js> node "g:\node js\urlmodule.js"
(node:1964) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
g:\node js\urlmodule.js:1
import url from 'url';
^^^^^^

at node:internal/main/run_main_module:17:47
the code was-
import url from 'url';
const myURL = new URL('https://example.org');
myURL.pathname = '/a/b/c';
myURL.search = '?d=e';
myURL.hash = '#fgh';
console.log(myURL)
console.log(myURL.href)

Try to set:
"type": "module"
In your package.json file.

You have to include "type": "module" in package.json file.

Looks like you don't have setup to support es6 imports. Try using commonJS imports:
Eg: const url = require('url');
If you wanna use es6 import please follow this.

NODE [ERR_MODULE_NOT_FOUND]: Cannot find module './config/app'

FIXED, the names of the folders in my pc changed when uploaded to github
So, my app looks something like this
├── config
| ├── app.js
|
└── index.js
app.js
Here i have all my env variables, so I have a central point from which to extract them
require('dotenv').config()
module.exports = {
appPort: process.env.PORT,
appUrl: process.env.APP_URL,
appKey: process.env.APP_KEY,
frontendUrl: process.env.FRONTEND_URL
}
index.js
central file of the server
const express = require('express')
const cors = require('cors')
const app = express()
const { appPort, frontendUrl } = require('./config/app')
app.listen(appPort , () => {
console.log(`Server listening on port ${appPort}`);
})
The problem here is that when i deploy it and starts the server, it throws me error
node:internal/modules/cjs/loader:936
throw err;
^
Error: Cannot find module './config/app'

}
and i really don't know why, because it works perfectly fine in my pc
the code for the whole project is actually much bigger, but only this files are the ones throwing me errors
Hope someone can help see what is happening that throws that error

}

first try to remove the globally installed express
then initialize a package.json file with npm init. Here you will have a list of your dependencies, scripts and name of your package and some other data.
Then install express with npm i express.
after installing try to run it with node server.js or npm start if you have written the script to run the start command in package.json

Gulp SyntaxError: Invalid or unexpected token

I just made an script to compile our scss when we save the file with gulp but I execute "gulp sass" I receive the next error:
gulp.task('sass', function () => {

This is the code:

const sass = require('gulp-sass');
sass.compiler = require('node-sass');
// Creates the task that will compile our scss
gulp.task('sass', () => {
// TODO: Must be a way to call a variable with scss route
return gulp.src('./cartridges/peru/cartridge/client/default/scss/**/*.scss')
.pipe(sass().on('error', sass.logError))
.pipe(gulp.dest('./cartridges/peru/cartridge/static/default/css'));
});
The thing is that it works just fine in my computer but it doesnt work in my partner's computer.
I have no clue of what could be happening.
Any help?

Node and Require import error in Mocha?

I have a working Node application and I'm trying to add Mocha tests, but getting some odd import errors.
This is my file structure:
package.json
index.js
src/
chart.js
highcharts-options.js
test/
test_chart.js
This is what my chart.js file looks like:
var chartOptions = require('./highcharts-options');
var analyseChart = {
doSomething: function() { ... }
};
module.exports = analyseChart;
And this is what highcharts-options.js looks like:
var HighCharts = require('highcharts-browserify');
Highcharts.theme = { ... };
Currently I import everything from /src into a single index.js file, then bundle it with browserify, which works just fine, no errors in the application.
Now I want to start writing Mocha tests for the functions in /src.
This is my first stub in test_chart.js:
var chart = require('../src/chart');
chart.doSomething();
But when I run mocha, I get the following error:
Users/.../js/src/highcharts-options.js:11
Highcharts.theme = {
^
ReferenceError: Highcharts is not defined

How can I fix this import error for Mocha?

var HighCharts = require('highcharts-browserify');
Highcharts.theme = { ... };
You have a spelling error.

How did you not notice this yourself even when you were told exactly what was wrong?
Some errors are so common that we ultimately stop trusting them, and start looking for other faults in our code without even investigating it.
This is especially true for the "someVar is undefined" error in javascript.
Takeaway:
Sometimes you just got to trust your error messages.
