I am trying to upload a Blob using my react native app but unable to do so.

Below code is not working in react native but working fine in web browser:-

const formdata = new FormData();
const content = '<a id="a"><b id="b">hey!</b></a>';
const blob = new Blob([content], { type: "text/xml" });

formdata.append("file", blob);

const requestOptions = {
  method: "POST",
  body: formdata,
  redirect: "follow",
};

fetch("https://some-upload-api-path", requestOptions)
  .then((response) => response.text())
  .then((result) => console.log(result))
  .catch((error) => console.log("error", error));

What’s the difference in uploading files in react native and web browsers.

Please don’t consider this a duplicate. I have searched many blogs and stuffs but haven’t reached to the solution.

First of all, my question is ‘how to resolve react state change in unmounted component error, and cancel an async function call that is imported within the useEffect hook?’

I know that you can resolve ‘state changed in an unmounted component‘ error by using clean up function in useEffect. In the cases of async call within useEffect hook, you can do clearTimeout, use cancel token for Axios, create [isMounted] state to flag mounted/unmounted state, and etc. So, at least, I know how to veil the react warning

However, my boss wants not only veiling the warning but also cancelling the async request. Here’s the simplified version of code.

import { fetchFunction } from '../../../somewhereInTheDir';

function Page() {
  const [data, setData] = useState([]);
  const [isMounted, setIsMounted] = useState(true);

  async function fetchData() {
    try {
      const data = await fetchFunction(someUri);

      setData(data);
    } catch (error) {
      console.warn(error);
    }
  }

  useEffect(() => {
    if(isMounted) {
      fetchData(ENDPOINT);
    }
    
    return () => {
      setIsMounted(false);
    }
  })
}

The isMounted state veils the warning. So I am seeing nothin in the console, which is a good sign. But this code does not block/cancel data coming from the endpoint when Page component is unmounted. And you cannot use strategies like putting cancel token in the http header, because fetchFunction is from outside.

ps. my boss said using isMounted state as if it were a JavaScript variable could be an anti-pattern from React, since React state change leads to a re-rendering. Is there a better way to veil the warning without using isMounted state?

I have tried to use craco but in in the browser showing nothing I am getting below error in the console.
Uncaught TypeError: Cannot read properties of undefined (reading 'prototype')

I’m working on a .NET 6 MVC project, which requires a form that will allow the user to generate <select> elements on the page with a button click. Each dropdown generated will have the same list of options minus any options already selected through the other dropdowns (so that a user can’t select the same option twice). Moreover, whenever a user selects an option using any of the dropdowns, a list of checkboxes that is specific to the option chosen is rendered below the dropdown.

If this description isn’t totally clear, my main point is simply that the form will need a lot of dynamic elements.

The model that I will pass to the form will already have all the properties that the form will need. So, there will be no need for any asynchronous calls to the server while the user is interacting with it. I want the submission to be a simple POST request to the controller of the bound fields.

So, what is the recommended way of building such a dynamic form within an existing MVC application? I thought of two approaches:

1. Creating a Blazor component with an EditForm, and including it on the page where the form needs to be displayed: I actually did this already, and the form works as intended. However, I’m having a hard time figuring out a good way of POSTing all the bound data to the MVC controller now (if anyone can lend any tips, I’d appreciate it).
2. Building the form within a normal MVC view, and using JavaScript for the dynamic parts: The advantage of this approach is that it wouldn’t have to disrupt the MVC’s usual way of submitting form data to the controller. But, I fear that JS code would be far more messy than the Blazor code I already wrote.

I would greatly appreciate any advice regarding the choosing between these two options, or any suggestions about alternative solutions.

Is there any way to be able to minify in webpack 5? I used this plugin before but it is now obsolete and incompatible with the webpack version, is there an alternative?..

I’m implementing a bubble chart on ReactJS with typescript using d3.js, I get the data, structure as according to what I need and and then pass it as nodes but I get an error that says name does not exist on type node.

I’m using :
“d3”: “3.5.17”,
and
“@types/d3”: “3.5.46”

error

Property 'name' does not exist on type 'Node'.  TS2339

        61 | 
        62 |                 var vis = svg.selectAll("circle").data(nodes, function(d, i) {
      > 63 |                   return d.name + i;
           |                            ^
        64 |                 });
        65 | 
        66 |                 vis

that’s how my data is structured

 let _data = Object.keys(data).map((key) => ({
                name: data[key].name,
                className: data[key].name,
                size: data[key].count,
                img: Rising,
            }))

and that’s the function to generate the d3 chart

(function() {
                let json = _data
                let svg = d3
                  .select(".bubble_chart")
                  .append("svg")
                  /*
                  .attr("width", diameter)
                  .attr("height", diameter);
              */
                  .attr("preserveAspectRatio", "xMinYMin meet")
                  .attr("viewBox", "0 0 600 400")
                  //class to make it responsive
                  .classed("svg-content-responsive", true);
              
                let bubble = d3.layout
                  .pack()
                  .size([600, 400])
                  .value(function(d: any) {
                    return d.size;
                  })
                  .padding(2);
              
                // generate data with calculated layout values
                var nodes = bubble.nodes(json).filter(function(d) {
                  return !d.children;
                }); // filter out the outer bubble
              
                var vis = svg.selectAll("circle").data(nodes, function(d, i) {
                  return d.name + i;
                });
              
                vis
                  .enter()
                  .append("circle")
                  .attr("transform", function(d: any) {
                    return "translate(" + d.x + "," + d.y + ")";
                  })
                  .attr("class", function(d: any) {
                    return d.className;
                  })
                  .attr("r", 0)
                  .transition()
                  .duration(1000)
                  .attr("r", function(d: any) {
                    return d.r;
                  });
              
                vis
                  .enter()
                  .append("svg:image").style('opacity', 0)
                  .attr("transform", (d: any) => "translate(" + d.x + "," + d.y + ")")
                  .attr('x', (d: any) => -(d.r/1.5)/2)
                  .attr('y', (d: any) => -(d.r/1.5)/2)
                  .attr("xlink:href", function(d: any) {
                    return d.img;
                  })
                  .attr("width", (d: any) => d.r / 1.5).transition().duration(1000).style('opacity', 1);
            })();

I have a HTML for select that have onchange call getProductFilter function. the script below

when I select the combo box for the first time it working just fine but after I select it twice and so on, the onchange function fired more than once show at console log like this

why is it fired more than once? any idea?

It is possible to know when a cookie expires? I have a function that gets a cookie:

function getCookie(cName) {
    const name = cName + "=";
    const cDecoded = decodeURIComponent(document.cookie);
    const cArr = cDecoded .split('; ');
    let res;
    cArr.forEach(val => {
        if (val.indexOf(name) === 0) res = val.substring(name.length);
    })
    return res;
}

But I need to know the expiration date also, not only the value.

Does someone know? I couldn’t find a solution.
Thanks

I have created 2 web applications using firebase and hosting. I am trying to create buttons that will sign in with Facebook, twitter, GitHub. I have a google button and that works no problem. However, the twitter, Facebook, and GitHub all ask for login info and then nothing happens. The console on Chrome gives no errors.

Here is my HTML code where I am running the scripts

Scenario:

Using flexbox, I’m creating a template where the number of ‘cards’ displayed can change from page to page. If a user adds 2, 3 or 4 cards – the layout is great.

However, if a user adds 5 cards, the layout is now less aesthetically pleasing with the 5th card alone on a new row.

Is there a way I can display up to 4 cards on a row, but if there are 5+ cards.. then the first row would display 3 cards, and the second row would display 2?

Here’s a general idea of how the code would be displayed.

<style>
.cards-wrapper {
display: flex;
flex-wrap: wrap;
}
.cards-wrapper .card {
flex: 1 1 20%;
margin: 10px;
}
</style>

<div class="cards-wrapper">

    <div class="card"> </div>

    <div class="card"> </div>

    <div class="card"> </div>

    <div class="card"> </div>

    <div class="card"> </div>

</div>

I’ve been brushing up on some forgotten skills for a interview recently, mainly sorting algorithms, and I’ve come across two different ways to do quick sort and I’m having trouble telling which one is the proper way of doing it. Does anyone know which one is correct?

Version 1:

const quickSort(arr, start, end){
  if (start >= end) {
        return;
  }
    
  let index = partition(arr, start, end);

  quickSort(arr, start, index - 1);
  quickSort(arr, index + 1, end);
}

function partition(arr, start, end){
  const pivotValue = arr[end];
  let pivotIndex = start;

  for (let i = start; i < end; i++) {
    if (arr[i] < pivotValue) {
      [arr[i], arr[pivotIndex]] = [arr[pivotIndex], arr[i]];
      pivotIndex++;
    }
  }
   
  [arr[pivotIndex], arr[end]] = [arr[end], arr[pivotIndex]] 
  return pivotIndex;
}

Version 2:

function QuickSort(Arr){
  if(Arr.length < 2) return Arr;

  const pivot = Arr[0];
  const leftArr = [];
  const rightArr = [];

  for(let i = 1; i < Arr.length; i++){
    if(Arr[i] < pivot){
      leftArr.push(Arr[i]);
    }
    else{
      rightArr.push(Arr[i])
    }
  }

  return [...QuickSort(leftArr), pivot, ...QuickSort(rightArr)];
}

//I have this Array
“ARRAY_1”:[FC2TADACI012: 2 ,FTVICBWI0014: 1];

//I need the array in this format
"ARRAY_2":["FC2TADACI012: 2","FTVICBWI0014: 1"];

Here on render of the above component I get all the question stored on the server side . Then I perform nested mapping in order to traverse and display the data . Also I set answers and submit it for the particular questionID . The problem I am facing is that when I post an answer I have to either reload the same component in order to get updated allQuestion array of object or I have to navigate to some other component the come back to this component , even navigating to the same component don’t work.
I just want to Display the answer on real-time without loading the component again before or after sending answerObj to the server.

The structure of allQuestion list of object

   allQuestion=[
    {
    "questionId":qid,
    ....,
    ....,
    ....,
    answers:[
    {
    "answerId":aid,
     .....
     },
     ]
     }]

So I have been re-iterating my code and working around with it for a few hours and I need help. My goal was to use “use-effect” to load an api call from a horoscope API. I ran into this error where I was only able to see the data AFTER I loaded another page from the website and re-rendered the homepage. My goal was to see the data displayed initially on UseEffect() from when I called it. However, it seems to not work. Not sure if I need to use setInitialState, or manipulate the way I am exporting the values through context.

On further speculation,
I somewhat see what the problem is in my code, but I have no idea HOW to use setInitialState to load values in from the api.

          initialState.data.yesterday = data;

? Do i save this to the a variable then call set data on that variable?

1.) I tried manipulating state best I could could.
2.) Page never loads data from API on first run, only shows data after I click a button
3.) Code seems to need setInitialDate but can’t find reasonable solution mixed with use effect to get the data right.

Thank you!!

I am willing to hear all optimal solutions for my problem. I am not even sure if I am going in the right direction. Thanks.
