Why is this async/Promise method running synchronously?

I'm really a noob in JavaScript and I'm trying to write a small ElectronJS/NodeJS app. I think the purpose of the App is not relevant to the question, suffice it to say that the App will listen to TCP connections that will send ~100MB of XML content and then will do some further processing on the parsed XML. Since the XML content is "large" the parsing is taking some time to process, so I decided to put the parsing in an asynchronous function but the code is apparently running synchronously. I'm not sure if I'm doing something wrong or if it's just because of the single-thread (AFAIU) nature of JavaScript. var net = require('net'); const fs = require('fs'); const { XMLParser, XMLBuilder, XMLValidator} = require("fast-xml-parser"); const parser = new XMLParser(); var file_counter = 0; var server = net.createServer(function(connection) { console.log('Client Connected'); var content = ""; connection.o...

Why am I not seeing a TypeScript error here?

I would expect the following code (inside an arbitrary Class) to show a TypeScript error in VSCode. But it doesn't. Why? protected someMethod (someArg?: boolean) { this.doSomething(someArg) } protected doSomething (mustBePassedBoolean: boolean) { /* ... */ } The tooltip doesn't even acknowledge that someArg should be boolean|undefined : I'm guessing this must be an eslint configuration error because the same thing in TypeScript playground acts as I would expect. But I'm not seeing any eslint configuration errors in the VSCode console. Any advice on troubleshooting VS Code eslint problems like this? Edit It's worth noting that I am seeing some expected TypeScript errors, in the same file. As far as I can tell this seems to only happen with vars I would expect to be cast as |undefined .

ChartJS Chart how to config Scales

I am creating a website about Bitcoins and using some interactive Charts from ChartJS. Until now the scales in the Charts are changing with the data.

I already tried to do this but it does't work: The trick with the max and min... scales:{ r: { ticks: { beginAtZero: true, min: 150, max: 150, stepSize: 10, If somebody could help me I would be really greatfull!

I am creating a page with image map that has a popup box. It works ok but I am not sure how to close the popup box when user clicks outside of the box or when the users scrolls the page.

Problem with accordion's toggle when combining it with navtabs (Bootstrap)

So, I'm creating this navigation thing using Bootstrap which will be present in the form of tabs in desktop and for mobile it will be an accordion. It's almost finished except there's this error I am not able to resolve. Problem: If I click on any of the tabs (say Link #3) in the desktop version and then I switch to mobile, the correct tab is opened (i.e. Link #3) BUT when I click on it to close the tab and hide the content even though the content gets hidden, the button and toggle remains in "open state". This problem can be seen in desktops or tablets (as they'll show the navtabs). To view the problem on desktop just decrease the viewport size after clicking the nav tab. I thought that if I could use "classList.contains()" to somehow keep track of when the content has "show" class and when it does not I'd be able to control it. But, I think it only keeps track of the class if I mentioned the class inline (it keeps on alerting true f...

useState does not set

First of all, yes, I talked with ChatGPT, it does not give a working answer. The main is that I want an image to be rendered. Why in my case the setter does not work? Probably the error lies on the surface, I am a newbie so please do not be strict. I am trying to set setMeme in two places, but it does not work. What's horroring for me is that I do not receive any error. I screened a few sites, but solutions mostly rely on "useEffect", and did not help this did not help: The useState set method is not reflecting a change immediately import React from "react"; import memesData from "../memesData.js"; import { useState, useEffect } from "react"; import front_img from "../../public/images/front_meme.png"; function importAll(r) { return r.keys().map(r); } const images = importAll(require.context('./', false, /\.(png|jpe?g|svg)$/)); //alert(images); // Create a require.context for the images folder //const images...

How to create multiple paths of different colour using Google StaticMap in Google Apps Script?

I am trying to create a small app that will take x number of lists of locations (in the form of Geocodable Addresses) and displaying them on a StaticMap as x different paths. To change the style of the paths the documentation says to use setPathStyle(weight, color, fillColor) When doing this though I cannot find a way to make the fill colour fully transparent, or to have no fill colour at all. I build the map and retrieve the URL using this Google Apps Script code (The real app is connected to a Google Sheets document with changing addresses which is why I am using GAS): function mainFn() { addressList = [[['London, UK'],['Milton Keynes, UK'],['Cambridge, UK']], [['Reading, UK'],['Oxford, UK'],['Bristol, UK']], [['Gloucester, UK'],['Worcester, UK'],['Birmingham, UK']]]; //would normally be sourced from a Google Sheets document directions = getDirections(addressList); map...

Pagination in Server Component Next js

Expand a certain div when loading from a web search

I have a webpage with a good amount of expandable divs. Since the text is hidden and a person coming in from a web search would have to open each div to check for the content, is there any way I can open the div when the page loads?

Now I search on google about the content in expandableDiv and my website shows up. When I click on it, the div would be hidden.

How to animate a line graph in python where each step of the animation draws an entirely new line based on data in dataframe and export as gif

I would like to animate a line graph in python based on data in my df. For each step in the animation, a line graph would be displayed using one row of the df. A fraction of a second later, a new line graph would be displayed using the next row of data in the df. This process would continue until each row of data had been separately displayed. After this process had been done for all rows, the graph would show the last line of data. I would also have code that converts the animation to a gif and then exports it. I'm lost as to how to do this and was hoping someone could point me in the right direction. Here is the code and df I have so far: # Import dependencies import pandas as pd from datetime import datetime # Create lists to be converted to df data = [['01/01/2016', 4.17, 4.42, 4.53, 4.71, 4.77, 4.72], ['02/05/2017', 4.59, 4.64, 4.70, 4.74, 4.80, 4.68], ['04/17/2018', 4.67, 4.82, 4.90, 5.02, 5.20, 5.06], ['03/03/...
