I am using node-worker-thread-pool package.I am unable to import certain node modules into my worker.ts, giving an error SyntaxError: Cannot use import statement outside a module. How to resolve this. Is there any other package which can help, since my task for worker thread have other import/module dependency?
import {Item} from "#package in node modules";

Initial error when trying to use #iconify-icons/cryptocurrency with next.js and typescript (it happens only when in typescript).

The problem does not happen with all libraries. It seems to me that during the transpilation babel has a problem with the library syntax.
Then I've tried to transpile the lib next-transpile-modules to fix the problem using the code below.
const withTM = require("next-transpile-modules")([
"#iconify-icons/cryptocurrency"
]);
module.exports = withTM();
But a new problem has happened.
Error: next-transpile-modules - an unexpected error happened when trying to resolve "#iconify-icons/cryptocurrency"
Error: Can't resolve '#iconify-icons/cryptocurrency' in '/sandbox'

To conclude, transpiling the module is the way I'm trying to achieve the main goal. It might not be necessary.
The way the #iconify-icons/cryptocurrency library is exported means you need to transpile each icon package you use individually.
const withTM = require("next-transpile-modules")([
"#iconify-icons/cryptocurrency/usdt"
]);
module.exports = withTM();
My goal is to use the logger.js inside my app.js
I typed this from a tutorial but I have got different results than the tutorial.
-node-tutorial
--logger.js
--app.js
When I type node app.js in the console, I get this:
timbliefert#Tims-Air node-tutorial % node app.js

module.exports(log) = log;

module.exports is an object by default and you haven't reassigned it to a function so you're not able to invoke it with parenthesis like a function. You can add properties to module.exports exactly like how you'd add them to an object in JS through assignment.
module.exports.log = log;
I want to run some function inside javascript file via the console.
I'm using Node v12.14.1.
My case is as follows:
I have a testIt.js file as follows:
import {settings} from "./config";
const someMainFunction = (testParam) => {
console.log("This is init");
console.log("This PARAM", testParam);
otherFunction();
};
const otherFunction = () => {
console.log("This is other function")
};
export { someMainFunction }
I want to run someMainFunction via console.
I tried with
node -e 'require("./testIt").someMainFunction("Testing...")'
But it doesn't work.
I do not want to use any external libraries.
Any idea how to do that?
UPDATE
I get an error as follows:
import {settings} from "./frontend/config";

Hey guys I'm new to JS and Node.js and I'm having trouble setting up a webdriverio project using cucumber and PageObject. And every time I try to run a test this error happens:

This is the loginStepsDef.js file where the openWebSite is being called:
import openWebsite from '../support/action/openWebsite';
import LoginPage from '../pageobject/LoginPage/LoginPage';
module.exports = function given() {
this.Given(
/^I open salesforce login page$/,
openWebsite
);
this.When(
/^I set user "([^"]*)?" and password "([^"]*)?"$/, function(arg1,arg2) {
LoginPage.open();
LoginPage.username.setValue(arg1)
LoginPage.password.setValue(arg2)
});
this.And(
/^I click the login button$/,function(){
LoginPage.open();
LoginPage.submit();
});
}
Any idea what could be happening would be great. Do you need me to show something more let me know.
Try with this :
var openWebsite = require('../../support/action/openWebsite');
var LoginPage = require('../../pageobject/LoginPage/LoginPage');
I got this error after updating react-native and react
I think this is right syntax, but I don't know why this error is shown:
this.list = function(table, callback, wheredata = [],selection = '',extra = '') {

You need to compile your code with Babel.js to use Ecmascript 6 features or if you want to work on es5, you can do like this
