Vercel giving 404 error when using a custom URL

I am developing a code playground. Everything works in my computer,
It has a saving system. Encodes your code and puts it in the URL. When page loads, gets the code from the URL. It works perfectly fine. It uses Vite, vanilla JS, and I used the Vite setting on Vercel, but the saving system doesn’t work. When you reload, instead of getting the code, It gives a 404 error message, as the URL isn’t on the dist folder.
What can I do?

I am trying to get firebase firestore documents and display some of its information on the browser

When I console.log the data I get from firestore inside the then() function as shown below, it displays the data without the problem. However, if I append that data in the peopleData variable and console.log the peopleData variable, I get an empty string.

let db = getFirestore();
let peopleCollection = collection(db, 'People');

getDocs(peopleCollection)
.then((people) =>{
    people.docs.forEach(person =>{
        let personData = person.data(person);
        console.log(`${personData.Name} is an ${personData.Occupation} aged ${personData.Age}`);
    })})
.catch(err =>{
    console.log(err)
})

Here I get an empty string logged

let peopleData = ``;
getDocs(peopleCollection)
.then((people) =>{
    people.docs.forEach(person =>{
        let personData = person.data(person);
        peopleData += `${personData.Name} is an ${personData.Occupation} aged ${personData.Age}`;
    })})
.catch(err =>{
    console.log(err)
})

console.log(peopleData);

Swiper slider event not working as expected with loop

https://codepen.io/wr234/pen/LYzBLbY

  $(".swiper-slide").click(function(e){
    console.log("test");
  });

Hi im using Swiper slider.

But the event does not run when clicking on an element created by loop.

If you click slider1 created with loop after slider4, console.log is not captured.

How can we make an event happen?

      $(".swiper-slide").click(function(e){
        console.log("test1");
      });

      $(".swiper-slide").on("click", function(e){
        console.log("test2");
      });
      
      var swiper = new Swiper(".mySwiper", {
            slidesPerView: 3,
            centeredSlides: false,
            spaceBetween: 10,
            loop: true,

How do I check if express server is running from python?

So I call my backend.js from my python code like this

# server is requested to start
startServer = subprocess.Popen(['node', 'backend.js'])
# startServer.wait()
if startServer.poll:
    print('Server could not be started')
    sys.exit()

And my backend.js contains

app.listen(port, () => {
  console.log(`Server is listening at http://localhost:${port}`);
});

How can the backend tell python that server for some reason failed to start and exit the program or server has started and now you can go ahead? I have tried waiting for the startServer to end but that just stops the python code until server is stopped. So is there a way by which the callback function in app.listen can send information to the python code?

Keyup not working for PWA angular even after changing from keypress

I have a function to validate in input field / date field. When using (keypress) it is working fine on web but not in mobile. And when I am using (keyup) , the validation is not working in web as well.

What is the permanent solution for PWA Angular for this issue ?

// to validate date in numberic and / only
  keyPressAlphanumeric(event: any) {
    var inp = String.fromCharCode(event.keyCode);
    if (/[0-9_/]/.test(inp)) {
      return true;
    } else {
      event.preventDefault();
      return false;
    }
  }


<input matInput [matDatepicker]="picker"  maxlength="10" [max]="maxDate" placeholder="MM/DD/YYYY" required
                formControlName="DOI" autocomplete="off" (keypress)="keyPressAlphanumeric($event)">

How can I use await for react-query data?

I should call an API then use it’s data as parameter for another request:

const { data, isLoading, error } = useQuery('fetchAvailableProducst', fetcher, { enabled: false });

const sendOrder = (categoryID) => {
  const availableProducst = /* function to fetch a list of category */
  const ids = [];
  availableProducst.map(item => {
    ids.push(item.id);
  });
  sendOrderMutation.mutate(ids);
}

the above code doesn’t work, I just written for mentioning to an idea… Actually I’m looking for a way to add something like await before availableProducst (which comes by useQuery()) to get list then fill ids and then call sendOrderMutation to send order…

But is there any way to use await for useQuery() data?

How do I use user input from a textbox as parameters to display information on a different HTML page?

I have 2 pages, index.html, and tracklist.html. For my webpage, I want to get an artist’s name and an album name from 2 text boxes on index.html, use those as the parameters for my getAlbumTracks() function, and display the array of tracks on tracklist.html after clicking a search button (button is on index.html).

Below I have my index.html, tracklist.html, and app.js, and as of right now, when I run getAlbumTracks() in the console on tracklist.html with manually inputted parameters, I am able to display the array on the page, like this: https://gyazo.com/af94a5c5966d9c1cbaea74369a35add2 but don’t know how to do it with user input from textboxes on a different page. I’m a bit new to javascript so any help is appreciated, thanks!

RegEx to stop user from entering negative values and special characters in input

const pattern = /^[+]?([0-9]+(?:[.][0-9]*)?|.[0-9]+)$/;

I am using above regex. Also, it says charCode is deprecated.

Is there a way to render a React component *UI* into Django without calling APIs?

I’ve been working on my Django App for a couple of months now and decided to use React as my front-end, which I know is bad habit for development and makes everything a lot more complicated. I run npm build for my front-end app with Django, but when I launch the Django Project, it shows me the Django Rest Apis. When I wanted it to show me my UI, I built in React. Everything in my Django settings should be correct from tutorials and documentations, so I believe that isn’t the issue. I’ve tried calling the my API’s but I believe that isn’t the issue either.

I am trying to keep everything as simple as possible, so if I’m missing stuff in my code I apologize, I just want to understand the very basics of React without having a lot of side code.

Here is my App.js

import React from 'react';
import './App.css';
import Form from './Form';



class App extends React.Component {
  render(){
    return(
        <Form />
      )
  }
}



export default App;

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';


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

retrieve json data, but it says object undefined [duplicate]

I am trying javascript to print out json data.
https://devsheet.com/code-snippet/editorjs-blocks-json-to-html-javascript/
I have tried this sample code but undefined problem occurs.

obj = '{"header":"John", "paragraph":30, "list":"New York"}';

html = '';
Object.keys(obj).forEach(function(block, index) {
        console.log(block['type']); // it prints undefined, it is expected to print keys (header, paragraph, etc.)
        switch (block['type']) {
        
        case 'paragraph':
            html += '<p>'+ block['data']['text'] +'</p>';
            break;
        
        case 'header':
            html += '<h'+ block['data']['level'] +'>'+ block['data']['text'] +'</h'+ block['data']['level'] +'>';
            break;
        ...
        ...

console.log(block[‘type’]); <—- it prints undefined, it is expected to print keys (header, paragraph, etc.)
How can I solve it?
