Here’s my App component –

import Sidebar from "./components/Sidebar";
import { useState } from "react";
import Project from "./components/Project";
import CreateProject from "./components/CreateProject";
import HomePage from "./components/HomePage";

function App() {
  const [mainArea, setMainArea] = useState(undefined);
  const [projects, setProjects] = useState([]);
  function handleMainArea() {
    console.log(mainArea)
    return(
      <div id = "main-area">
        {
          mainArea  ?  <Project /> : <CreateProject onSaveProject = {handleSaveProject} onCancel = {handleCancel}/>
        }
      </div>
      );
  }
  function handleSaveProject(projectDetails) {
    console.log('here')
    setProjects((projects) => {
      let tempProjects = [...projects];
      tempProjects.push(projectDetails);
      return tempProjects;
    })
    //setMainArea(undefined)
  }
  function handleCancel() {
    setMainArea(undefined)
  }
  function handleAddProject() {
    setMainArea(false)
  }
  return (
    <>
      <Sidebar onAddProject={handleAddProject} projects={[...projects]} />
      {mainArea === undefined ? <HomePage /> : handleMainArea()}
    </>
  );
}

export default App;

Here’s my CreateProject component –

import { useRef } from "react"
export default function CreateProject({onSaveProject, onCancel}) {
    const titleRef = useRef();
    const descrRef = useRef();
    const dateRef = useRef();
    function onSubmit() {
        const projectDetails = {};
        projectDetails.title = titleRef.current.value;
        projectDetails.description = descrRef.current.value;
        projectDetails.date = dateRef.current.value;
        onSaveProject(projectDetails);
    }
    return(
        <form id="myform" >
            <div id = "buttonHeader">
                <button id = "cancel" onClick = {onCancel}>
                    Cancel
                </button> 
                <button id = "save" onClick = {onSubmit}>
                    Save
                </button>
            </div>
            <label>
                TITLE
            </label> <br></br>
            <input ref = {titleRef} type = "text" className = "input" id = "titleInput"></input> <br></br>
            <label>
                DESCRIPTION
            </label> <br></br>
            <textarea ref = {descrRef} type = "text" className = "input" id = "descriptionInput"></textarea> <br></br>
            <label>
                DUE DATE
            </label> <br></br>
            <input ref = {dateRef} type = "date" id = "dateInput"></input> <br></br>
            
        </form>
       
    )
}

When I click on AddProject button, the handleAddProject() is called, which sets the mainArea to false, and displays the CreateProject component, which is just a form.

Now, when I submit this form, the handleSaveProject function is called, which should update the state of projects and re-renders the page. But I am encountering a weird bug here, where my entire app is resetting, erasing all states, etc.

(This bug is solved if I just uncomment the setMainArea(undefined) in the handleSaveProject function. But I am trying to understand why it occurs in the first place)

I am working on a guessing game where Java holds a random number from 1-50. The user has unlimited tries, and will be told if they were too high or too low. Once they get it correct, I let them know and tell them how many tries they took. I just don’t know how to get the correct amount of tries without errors. And yes, this is an assignment so I would just like a little help without solving it for me completely.

I tried myGuess.length, which obviously wouldn’t work but I wanted it as a placeholder for now. I also tried holding a const or var and then placing it into the loop with increments, and calling it back. I actually didn’t expect it to work because I didn’t see the logic behind it. Also I am using Brackets.

I’m trying to make my webpage to refresh when a user deletes an album from a digital record collection. I’ve tried a few different options with no luck and cant seem to find out what the problem is. Here’s my code. I’d really appreciate any help! Some comments are from previous things I’ve tried.

import React from "react";
import { useState, useEffect } from "react";
import { Link } from "react-router-dom";4
import { useGetSingleCollectionQuery } from '../src/api/spinsapi'; 
import { fetchCollectionAlbumsById, fetchCollectionById, fetchSpotifyAlbumArt, deleteCollectionAlbum, deleteCollectionById} from "../fetching"
// import styles from "../index.css"; 
import { useNavigate} from "react-router-dom";
import { useParams } from "react-router-dom";


export default function SingleCollection ({token, setToken, spotifyToken}) {
  const { id } = useParams()
  const [error, setError] = useState(null)
  const backToCollections = useNavigate()
  const [albums, setAlbums] = useState([])
  const [collection, setCollection] = useState({})
  const nav = useNavigate()
  // const newCollectionPage = () => {
  //   const { isLoading, data, isError, error, isFetching } = useGetSingleCollectionQuery(
  //     'collections',
  //     fetchCollectionAlbumsById,
  //     {refetchOnMount: true,
  //     }
      
  //   )
  //   console.log({isLoading, isFetching})

  //   if (isLoading) {
  //     return <h1>Loading...</h1>
  //   }
  //   if (isError) {
  //     return <h2>error.message</h2>
  //   }
  // }
  // // const [reducerValue, forceUpdate] = useReducer(x => x + 1, 0);

  useEffect(() => {
    async function fetchCollection() {
      let res = await fetchCollectionAlbumsById(id)
      const coll_res = await fetchCollectionById(id)
      setCollection(coll_res)
      console.log(coll_res)
      async function fetchArt(albs) {
        await albs.forEach(async (album) => {
          let url = await fetchSpotifyAlbumArt(album.title, album.artist, spotifyToken)
          album.imgUrl = url
          albums.push(album)
        })
      }
      fetchArt(res)
      console.log(res)
    }

    fetchCollection()
  }, [])

async function removeAlbum(album_id) {
    let removedAlbum = await deleteCollectionAlbum(album_id, token, id)
    console.log(removedAlbum)
    // refetch();
  }

async function deleteCollection() {
  let deletedCollection = await deleteCollectionById(id, token)
  nav('/collections')

}

return (
  <>
  <div key={id} className="singleCollection column">
    <h1>{collection.name}</h1>
    <div className="all-albums-container">
      {albums.map((album) => {
        console.log(album.imgUrl)
        return (
        <ul key={album.id} className="album-card">
          <Link to={`/albums/${album.id}`}><img src={album.imgUrl} alt={album.title} /></Link>
            <li>{album.title} </li> 
            <li>{album.artist}</li> 
             <button onClick={() => removeAlbum(album.id)}>Remove</button>
        </ul>)
      })}
    </div>
  </div>
        <button onClick={() => deleteCollection()}>Delete Collection</button>
        <button onClick={() => backToCollections('/collections')}>Return To Collections</button>
  </>
  );
  }

Everything I’ve tried putting something in the dependency array within useEffect so it’s updated on that change too, but I may have been putting the wrong call in there.

I am currently using the Stripe Payment Element in my React application with the following code:

import { useStripe, useElements, PaymentElement, } from '@stripe/react-stripe-js'

export const PaymentDetails = () => {
  const stripe = useStripe()
  const elements = useElements()

  const paymentElementOptions = {
    layout: 'tabs',
    paymentMethodOrder: ['card']
  }

  return (
    <div className="mb-4">
      <PaymentElement
        id="payment-element"
        options={paymentElementOptions}
      />
    </div>
  )
}

I want to customize the appearance of this payment element align with the theme of my application, specifically changing the colorText for the labels above input fields.

I have reviewed the Stripe documentation, however I wasn’t able to amend the appearance of the payment element.

Any help would be appreciated. Thanks!

I am trying to set values of a 2d array at the specific index.

Each iteration is setting all contained arrays at the j index to the variable(number).

inputTensor dimensions 140x7 - 140 arrays of 7 
inputMinArray dimensions 1x7 - 1 array of 7 
inputMaxArray dimensions 1x7 - 1 array of 7 

  var transformedInputTensor = new Array(inputTensor.length).fill(new Array(inputTensor[0].length))
  for(let i = 0; i< inputTensor.length; i++){
    for(let j = 0; j< inputTensor[0].length; j++ ){
      number = scale(inputTensor[i][j], inputMinArray[j],inputMaxArray[j], outMin, outMax);
      transformedInputTensor[i][j] = number;
    }
  }

The function scale() only returns a single value.

Everything works as expected, except transformedInputTensor[i][j] = number;.

Have I missed something very simple or any suggestions? – Thank You

I’ve tried to create a new react directory with npx create-react-app and with every solution I’ve tried, the template was not provided with the recommended reasoning being that I might be using an outdated version of create-react-app.

I’ve checked what version of React is being downloaded and it up to date (18.2.0).

I’ve cleared the cache in my directory, uninstalled create-react-app globally multiple times, checked in my ‘~/users/name’ directory to manually delete it. I installed with both npx create-react-app@latest and without @latest.

Installing react, react-dom, and react-scripts...

I have a input that i want to recive any number (dont matter if its negative, float, long) i code this to now allow null, undefined or empty values, but if I enter 0 it is read as empty

const inputElement = Number(document.getElementById("inputNumber").value);
  if (!inputElement) {
    window.alert("Insira um valor válido");
    return;
  }

i already tried this but dont work

if (!inputElement && inputElement != 0){
  window.alert("Insira um valor válido");
  return;
 }

Does anyone know how to differentiate 0 from empty or vice versa?

I’m currently working on implementing a signup feature using Firebase Auth. To ensure security, I’ve placed my Firebase config within an action function, despite understanding that the risks of exposing config values on the client side are minimal. The signup process itself is functioning smoothly. However, I’m encountering an issue with the error handling part of my code. Specifically, the code within my catch block doesn’t seem to trigger at all, even in scenarios where it is expected to throw an error code snippet

I would expect an error to occur, such as signing up with credentials that have already been used. There’s no feedback or error message on either the client or the server side in these cases. Could anyone offer some insights or suggestions on what might be causing this issue and how to resolve it?

I have two arrays: A and B, A contains all elements of B, A also contains some other elements.
When array B changes, array A should be updated according B, here’re some rules:

1. in array A, we must keep the elements that not belong to array B and keep their order.
2. we can add new elements to array B, the new elements are added at the end of array B, and they are also added to the array A, following closely with the last element of array B in array A.
3. we can switch the position of two elements in array B, and relative elements in array A will also switch their position.
4. we can add new elements to array B and meanwhile switch positions of some elements (multiple switches), the array A should be updated according the 3 rules above.

I want to write a function taking 3 parameters: A, B, BX, and it will return the updated array A (we call it as AX).
Here’re some examples:

1. A = [a1, a2, b1, a3, b2, b3, a4], B = [b1, b2, b3], BX = [b3, b2, b1], then AX = [a1, a2, b3, a3, b2, b1, a4]
   

2. A = [a1, a2, b1, a3, b2, b3, a4], B = [b1, b2, b3], BX = [b3, b1, b2], then AX = [a1, a2, b3, a3, b1, b2, a4]
   

3. A = [a1, a2, b1, a3, b2, b3, a4], B = [b1, b2, b3], BX = [b1, b2, b3, b4, b5], then AX = [a1, a2, b1, a3, b2, b3, b4, b5, a4]
   

4. A = [a1, a2, b1, a3, b2, b3, a4], B = [b1, b2, b3], BX = [b3, b1, b2, b4, b5], then AX = [a1, a2, b3, a3, b1, b2, b4, b5, a4]
   

5. A = [a1, a2, b1, a3, b2, b3, a4], B = [b1, b2, b3], BX = [b4, b3, b1, b2, b5], then AX = [a1, a2, b4, b3, a3, b1, b2, b5, a4]
   

6. A = [a1, a2, b1, a3, b2, b3, a4], B = [b1, b2, b3], BX = [b4, b3, b1, b5, b2], then AX = [a1, a2, b4, b3, a3, b1, b5, b2, a4]
   

How can this be done?

Problem statement: I am tring to import a Navbar component that is built using the Radix library into the root component App.js of my react application. I have tried both name and default export to render the component. None of these options work.

Error that comes in Live Server

Code setup and App.js file

Navbar Component

Troubleshoots:

I have tried renaming the components to resolve any possible conflicts. Also, I used different export and import convention built for react. None of these solutions work.I adjusted the file paths but it doesn’t help either.

Can you kindly help me?

I am trying to make a very simple project as one of my first react projects ever. What i tried to accomplish is making a simple input and making it print itself as i type however it doesn’t do anything. This is the code i wrote so far:

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

function App() {

  const [userInput, setUserInput] = React.useState('')

  const handleChange = (event) => {
    console.log(event.target.value)
    setUserInput(event.target.value)
  }

  return (
    <div className="App">
      <Header userInput={userInput} handleChange={handleChange}/>
      <h1>{userInput}</h1>
    </div>
  );
}

export default App;

---

import React from "react";
import './Header.css'

const Header = ({userInput, handleChange}) => {
    return (
        <div className="headerContainer">
            <picture>
                <img alt='Something' className="logo"></img>
            </picture>
            <div>
                <label>Event:</label>
                <input type="text" onChange={handleChange} value={userInput}/><br /><br/>
            </div>
        </div>
    )
}
export default Header

I tried debugging, asked ChatGPT and Googling.`

I want to be able to intercept the video/audio being received by the player and analyze it as it is being received by the socket much before it is played by the player. If possible, I’d also need the stream information (where on the buffer is the player at). In sum, I want to synchronize an external audio player with twitch’s video player.

Reversal engenier seems to be the way, but it seems very convoluted. Looking at the network traffic, the response for what it seems to be the stream data doesn’t look readable and looking trough the javascript is a bit inconvinient. Tried to search for the video tag inside the js file as it might be what is manipulated, but nothing useful.

Looked it up if someone knows how to mess around with the played, but most google searches are unreleated

Actually I have a link of one JSON format file. And I want to fetch url of MP4 video. Please help me in JavaScript
Link = JSON file
