I want to add a child-component ColorBox in return of parent component ColorBoxContainer based on No of times there is a value in state noOfBoxes: 16. I am trying doing using for-loop but I guess the code is wrong. Can someone help me out, how to achieve this?

import React, { Component } from 'react';
import ColorBox from './ColorBox';

class ColorBoxContainer extends Component {

  constructor(props) {
    super(props);
    this.state = {
      noOfBoxes: 16
    }
  }

  render(){
    return (
      <div>
        {for(i=0;i<this.state.noOfBoxes;i++){
           <ColorBox />
        }}
      </div>
    )
  }  
}

export default ColorBoxContainer1;

I’m trying to use child_process to open another program through electron, but when I click the button even calling the function to render it doesn’t open the requested application.

Electron version ^16.0.7:

main.js

const { app, shell, BrowserWindow } = require('electron')
const path = require('path')

let mainWindow = null;

function createWindow () {
  mainWindow = new BrowserWindow({
    autoHideMenuBar: true,
    width: 1300,
    height: 840,
    resizable: false,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js'),
      webPreferences: {nodeIntegration: true}
    }
  })

  mainWindow.loadFile('./app/home.html')

}

app.whenReady().then(() => {
  createWindow()

  app.on('activate', () => {
    if (BrowserWindow.getAllWindows().length === 0) {
      createWindow()
    }
  })
})

app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('web-contents-created', (e, contents) => {
  contents.on('new-window', (e, url) => {
    e.preventDefault();
    require('open')(url);
  });
  contents.on('will-navigate', (e, url) => {
    if (url !== contents.getURL()) e.preventDefault(), require('open')(url);
  });
});

preload.js

window.openGaeme = function(executablePath) {
  let child = require('child_process').execFile;
  child(executablePath, function(err, data) {
    if(err){
       console.error(err);
       return;
    }
 
    console.log(data.toString());
});
}

function in renderer.js

function onClick() {
    var executablePath1 = "C:\Program Files (x86)\Game\system\game.exe";
    window.openGaeme(executablePath1);
}

HTML BUTTON AND SCRIPT:

<button class="button-go" role="button" onclick="onClick()">JOIN</button>

<script src="./core/renderer.js"></script>

This is my state:

const [time, setTime] = useState(10)

And this is my handler:

const runTimer = () => {
    useEffect(() => {
        const interval = setInterval(() => {
            console.log(time)
            if (time > 0) {
                setTime(time - 1)
            } else {
                console.log("End")
            }
        }, 1000);
        return () => clearInterval(interval)
    }, [])
}

My log:

9
9
9
9
9
.
.
.

Why setTime doesn’t work ?

time variable most increase per 1000 delay

Hi I am using a simple useReducer Function to Start and Stop a Lottie Animation for a Hamburger Menu Icon
Please suggest a better approach or something with faster performance if it exists or let me know if it is good enough.
Thanks in Advance

import Lottie from 'react-lottie-player/dist/LottiePlayerLight' //@ Lottie Player
import menuIcon from './menu-icon.json' //@ Lottie Menu Icon
import { useReducer } from 'react'

const Menu = () => {
  
  //$ Reducer Hook for Menu State Management
  //@ Reducer Function
  const controlAnim = (controls, action) => {
    switch (action) {
      case 'OPEN':
        return { isClicked: true, close: false }
      case 'CLOSE':
        return { isClicked: true, close: true }
      case 'SWITCH':
        return { isClicked: false, close: !controls.close }
      default:
        return controls
    }
  }
  //@ States and Controls
  const [controls, setControls] = useReducer(controlAnim, {
    isClicked: false,
    close: false,
  })

  return (
        <div className="menu-header-button" onClick={() => (controls.close ? setControls('CLOSE') : setControls('OPEN'))}>
          <Lottie
            className="menu-header-button-lottie"
            animationData={menuIcon}
            loop={false}
            speed={1}
            play={controls.isClicked}
            direction={1}
            segments={controls.close ? [55, 90] : [15, 45]}
            onComplete={() => setControls('SWITCH')}
          />
    </div>
  )
}

export default Menu

JS:

import React from "react";
import { ReactDOM } from "react";
import './style.css';
import App2 from "./App2.js";

function App() {
    return (
        <App2.js />
    )
}

ReactDOM.render(<App />, document.getElementById('root'))

Referred App2.js in the above file:

import React from "react";
import { ReactDOM } from "react";

export default function App2() {
    return (
        <div>
            <h1>Yusif Ahmedov</h1>
            <button id="email"></button>
            <button id="linkedin"></button>
            <h2>Front-End Developer</h2>
            <header id="about-header">About</header>
            <p id="about">I am a front-end developer who is passionate about coding and engaging both creative and practical side of the human potential.</p>
            <header id="interests-header">Interests</header>
            <p id="interests">Productivity articles, Time Management, Coffee, Music, Sports, Social Activities.</p>
        </div>
    )
    }

And simple HTML:

<!DOCTYPE HTML>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My Card</title>
    <script type="module" src="./App.js" defer></script>
</head>
<body>
    <div id="root"></div>
</body>
</html>

I wrote all from scratch and so there are no extra files.
When I run it, it gives an error:
Uncaught SyntaxError: Unexpected token ‘<‘ App.js:8(line)

I didn’t get it why it gives an error on the 8th line.

I need to recursively call an API to walk down child entries, and return the filtered results before continuing. I was initially putting the results in an array, and then doing a .forEach, and if I found a match I needed to recurse doing so; however, that didn’t work because of the problem described in the answer to this question. So, I tried to modify the answer to that question, but it’s still not waiting.

const getDatabases = async (blockId) => {
  let databases = [];
  let childDatabases = [];
    
  const children = await getChildren(blockId);
  Promise.all(children.results
    .filter( (child) => {
      return (['child_database', 'database'].includes(child.type)
        || child.has_children === true);
    })
    .map( async (child) => {
      if (['child_database', 'database'].includes(child.type)) {
        return { id: child.id, title: child.child_database.title };
      } else {
        console.log(`Waiting on getDatabases for ${child.id}`); // 1
        childDatabases = await getDatabases(child.id);
        return false;
      }
    })  
  )
    .then((childDbs) => {
      console.log(`Got childDbs`); // 3, 4
      databases = 
        [...databases, ...childDatabases].filter(dbId => dbId !== false);
      return databases;
    })
    .catch((err) => console.log(err));

}

app.get('/api', async (req, res) => {
  const dashboardPage = await getDashboardPage();
  const databases = await getDatabases(dashboardPage);
  console.log('No longer awaiting getDatabases'); // 2
  ...
}

So the question is, why is 2 happening before 3 and 4, instead of after them? Shouldn’t const databases = await getDatabases(dashboardPage); before 2 be waiting for all the recursive calls that pass through childDatabases = await getDatabases(child.id); after 1?

We are going to develop a dashboard for internal use using Nuxt.js. As this will be an internal dashboard there is no need for a universal mode. Generally most of the dashboard are developed in SPA.

But SPA also requires a server to send the initial HTML and js bundle to the browser. So what if we use SSG and deploy it to s3 as it will no longer need a server and we can save the cost?

I want users to be able to click on a certain area on the body (as image) where they endure pain, i want to ask what is the best way to accomplish this?
Kind regards!

When scrolling down, the class is added and immediately removed, which is seen in this video https://radikal.ru/video/Ua66Nz79e5D -radikal.

need to make the script work correctly so that the header is removed, and the block with the player is stretched to the full screen by height 100vh

html

<div class="oneboss">
    <div class="header">HEADER</div>
    <div class="main">
        <div class="player"></div>
    </div>
</div>

css

body {
    width: 100%;
    min-height: 100%;
    overflow-x: hidden;
}

.oneboss {
    display: flex;
    flex-direction: column;
    height: 100vh;
    overflow: hidden;
    position: relative;
}

.main {
    width: 100%;
    overflow: hidden;
    overflow-y: auto;
    position: relative;
}

.player {
    //there is nothing
}

js jq

const $header = $(".header")
let prevScroll
let lastShowPos

$('.main').scroll(function() {
  const scrolled = $('.main').scrollTop()

  if (scrolled > 0 && scrolled > prevScroll) {
    $header.addClass("header_hide")
    lastShowPos = scrolled
  } else if (scrolled <= Math.max(lastShowPos - 255, 0)) {
    $header.removeClass("header_hide")
  }
  prevScroll = scrolled
});

this class is being added.

.header_hide {
  display:none;
}

pls tell me how do solve this?

I am trying to get PanelSnap.js work on my wordpresssite.
My coding experience is like read manuals and copy-paste. So I am sorry if basic stuff isn`t right.

I downloaded the panelsnap.js the developer uses on panelsnap.com/panelsnap.js and took the file to upload it to the server (in the child-themes-directory). After that i added this line to the functions.php in the child-theme.

wp_enqueue_script( 'panelSnap', get_template_directory_uri() . '/js/panelsnap.js', array ( 'jquery' ), 1.1, true);

Next step was to use the “Simple Custom CSS and JS”-PlugIn to add some HTML to the Header

      <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/jquery.js"></script>
<script src="/wp-content/themes/kadence-child/assets/js/panelsnap.js"></script>
    
<script>
      jQuery(function () {
        new PanelSnap();
      })
    </script>

<script src="/wp-content/themes/kadence-child/assets/js/panelsnap.js" defer></script>
    <script>
        document.addEventListener("DOMContentLoaded", function() {
          new PanelSnap();
        });
    </script>
<script>
  var defaultOptions = {
    container: document.body,
    panelSelector: '> section',
    directionThreshold: 50,
    delay: 0,
    duration: 300,
    easing: function(t) { return t },
  };

  new PanelSnap(options);
</script>

and some JS in to the footer

 jQuery(document).ready(function( $ ){
var options = {
// jQuery object referencing a menu that contains menu items
$menu: false, 
// CSS selector to menu items (scoped within the menu)
menuSelector: 'a',
// css selector to panels (scoped within the container)
panelSelector: 'section', 
// jQuery event namespace that's being used
namespace: '.panelSnap',
// fired before a panel is being snapped
onSnapStart: function(){}, 
// fired after a panel was snapped
onSnapFinish: function(){}, 
// fired before a panel is being snapped.
onActivate: function(){},
// An integer specifying the ammount of pixels required to scroll 
// before the plugin detects a direction and snaps to the next panel.
directionThreshold: 50, 
// The ammount of miliseconds in which the plugin snaps to the desired panel
slideSpeed: 200,
// The jQuery easing animation to use.
easing: 'linear',
// An integer specifying the number of pixels to offset when snapping to a panel.
offset: 0,
// keyboard navigation.
keyboardNavigation: {
  enabled: false,
  nextPanelKey: 40,
  previousPanelKey: 38,
  wrapAround: true
},
strictContainerSelection: true
};
jQuery('body').panelSnap(options);
  });

If I open the site and the console it gives me this

Click to open

I tried even to build one of the sites like should be similiar to the developers demo.

Thank you for your time reading this and i would appreciate every help or critics.

Soo. I am getting an infinite loading screen when I start my react app. Eventually after waiting like 2 minutes it says Error code: Out of Memory. I tried lazy loading with seperate components in seperate files and it stills does the same thing.
