Find important nodes and edges with their edge connection count in cytoscape.js

I am using a cytoscape.js chart for showing data with nodes and edges. I know the cytoscape.js chart may encounter some performance issues while rendering a large number of data (like people collaboration chart). I am looking for any inbuilt function available to find the important nodes with their edges in the chart canvas and remove the other nodes and their relation. I think the cytoscape.js library doesn’t provide any straightforward method to achieve this.
Any help is much appreciated.

code coverage results doesn’t reflect results of unit test cases written for electron js code

I am able to write test cases for electron.js POC code but their results are not reflecting on nyc code coverage results. As per my understanding, code coverage HTML results files should reflect the covered test cases, but it’s not happening. I have tried to find a solution on google, but no luck so far. I didn’t get much about the code coverage for electron code on google, Badly stuck with this task. I am desperately looking out for the solution. Hence, I thought to raise my doubt in this forum.

Any suggestion or input would be highly appreciated & great help to me! Thanks for reading .

How to efficiently make multiple api calls from an array in node js

I have the following snippet of code to make multiple api calls

var userdetails:any=[]
for(var i=0;i<userids.length;i++)
            {
                               userdetails.push(await this.getUserData(authToken,userid[i]))
            }

Implementation of get userdetails function is as follows

async getUserData(authtoken,userid) {
        return new Promise((resolve, reject) => {
        
            const url = `https://***********/***/users?id=userid`;
            const requestOptions = {
                url,
                method: 'GET',
                headers: {
                    'Authorization': authtoken,
                }
            };
            request(requestOptions, (err, response, body) => {
                let errorMessage = 'Error in getting data';
                if (err) {
                    
                    return reject(err);
                }

                if (!response) {
                    
                    return reject({
                        message: errorMessage
                    });
                }

                if (response.statusCode === 200) {
                    
                    try {
                        body = JSON.parse(body);
                    } catch (err) {
                        
                        reject({ message: errorMessage });
                    }
                    if (isArray(body)) {
                        let newArray: any = [];
                        body.forEach(element => {
                            newArray.push({         
                                userId:element["userId"],
                                username:element["username"],
                                
                            });
                        });
                        return resolve(newArray);
                    } else {
                        return resolve(body);
                    }
                }

                if (response.statusCode >= 400) {
                    return reject({
                        message: errorMessage
                    });
                }
            });
        });
    }

The above code works just fine and returns all the data. But there is a performance glitch in it and it is taking lot of time to return the data as the number of userid’s increase. I am already using async await approach. What can I do to tune the performance of this code?

The chart does not appear although no error message in console (chart.js)

I am publishing the bar chart using JSON data and AJAX. The chart does not appear although no error showed in console. I am confused what is the problem because I was able to build another chart using the same way. Is there anyone can give me some clue please?

This is my codes in HTML file:

Note, the errors are shown in example 1 and example 2 are in different repositories as this error is happening with every project, I thought it best to show the two different steps.

Not sure if these errors are related. From searching online, I found that the following part of the error

npm ERR! code 1

Is from a conflict with node versions. As I result, I have tried brew install node@14 to step down versions, but brew link did not seem to work / did not resolve this error.

Any advise would be greatly appreciated.

I have also tried reinstalling the packages one at a time, which didn’t prevent me from installing at any point, but seemed to give a bunch of random errors on running “gulp dev” that were unclear to me.

Here is my package.json, as this will likely be required

javascript reposition overflow table scroll position

I am drawing a table using a function after data is received from a GET request.
After I draw the table, I want to hold the scroll position relative to the previous table that was there before (all tables have overflow:auto;).

The way I overcome this problem is as follows:

  1. listen to the scroll
  2. store the scroll position in sessionStorage
  3. After the new table is drawn, I use .scrolLeft = sessionStorage.getItem('PosY')

This works fine as it does what I want it to do, but I get the following from Chrome Dev.

[Violation] Forced reflow while executing JavaScript took 51ms

I understand why I get this from Chrome Dev. but I want to know if there is another way to do this that will not give me this [Violation]

I have looked into listening to the DOM and repositioning upon changes, but this gives the same [Violation]

Any suggestions would be much appreciated, especially if there is some simple CSS.

No jQuery OR other Libraries, please.

Is there any way that React component still keep the value from previous render?

I have a parent component, that render one child component several time. This child component is used in many different components. I need to have an array in this child component that keeps all the previous renders of the component, then get access to the largest text passed to it.

import TextComponent from '../../text'
const ParentComponent = ()=>{
  // ... some code here and get some data from API
 const text = getTextFromAPI()
  return (
   <>
    <ARandomComponent/>
    <AnotherRandomComponent/>
    <TextComponent text={text}/>
  </>)
}

In the TextComponent I need to know what text each element received, and return the largest text. I thought maybe I can have an array inside TextComponent but of course with each render, component has fresh data and I know this is by design.

Is there any way to active this? To store a value in the TextComponent that other renders from different places still have access to that value

How to pass DotNetObjectReference to JS DOM-event

I am trying to utilise JS drag & drop in Blazor, which works fine in general but I want to set a custom drag image during the ondragstart event. In general my code looks like this:

<div class="some-draggable-container"
     draggable="true"
     ondragstart="Element.dragStartHandler(event, '@(ImageSrcBase64)')" >
</div>
Element.dragStartHandler = function(event, imgSrcBase64) {
    var img = new Image();
    img.src = imgSrcBase64;
    event.dataTransfer.setDragImage(img, 0, 0);
}

The problem occurring to me is that I need to call a .Net function after setting the drag image and I cannot find a way to pass the needed DotNetObjectReference through to the JS part.

Simply passing the newly created objectRef into the JS event call leads to an Unexpected end of input error.

ondragstart="Element.dragStartHandler(event, '@(ImageSrcBase64)', @(DotNetObjectReference.Create(this)))"

Also using the JsonSerializer does not do the trick. It surely does serialise the object and JS is able to deserialise it, but as expected the DotNet.invokeMethod() methods are not present.

ondragstart="Element.dragStartHandler(event, '@(ImageSrcBase64)', @(JsonSerializer.Serialize(DotNetObjectReference.Create(this))))"

Utilising the Blazor event and handling it fully in .Net does not offer the ability to set the drag image because the passed DragEventArgs are not fully compliant to the JS one.

Passing the event args through IJSRuntime into a JS function leads to errors because it’s just not the same thing as the native JS event, so at least the setDragImage() Method is missing.

Is there any way to make this work? I don’t want to juggle around with JS-to-static-.Net calls and guids or that kind of workaround.

Jumpy CSS transition in sidebar links text while toggle transition is running

When collapsing, the text adapts to the width of the sidebar progressively which causes a jumpy transition

Example:

enter image description here

As you can see the text Collapse sidebar appears in two lines instead of a single line of text.

Desired result:

enter image description here

LIVE JS FIDDLE

I would like to know if there is any mechanism to show the text only when it fits 100% in the sidebar and it is not cut in two lines.

I need is the text to appear only after the transition of the collapse has finished.

What I’ve tried:

-Increasing/decreasing the transition time (too radical, works if I delete the transition but somehow has to be smooth so it’s not a valid solution)

.sidebar{
    position: fixed;
    top: 0;
    left: 0;
    height: 100%;
    width: 290px;
    background: #193D4C;
    z-index: 100;
    transition: all 0.5s ease;
}

-Using backface-visibility property. Did not work.

-Using Bootstrap 5 event type shown.bs.collapse like this:

var myCollapsible = document.getElementById('sidebar')
myCollapsible.addEventListener('shown.bs.collapse', function () {
  alert("it works!"); //This never gets fired
})

I’ve been looking for a similar question for a long time but I didn’t find anything

How will i filter sitemap urls by last modification date of today in google app script?

with the code below am able to retrieve a site’s sitemap urls and last modification dates. the problem is that there are over 600 urls retrieved, how will i filter in the script to only show urls with the last modification date of today, removing urls with old dates?

var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName(‘Sheet1’);

//Create function that fires when menu item clicked.

function getLinks() {

var xml = UrlFetchApp.fetch(‘https://example.com/blog_listing-sitemap.xml’).getContentText();

var xml = XmlService.parse(xml);

var root = xml.getRootElement();

var ns = XmlService.getNamespace(‘http://www.sitemaps.org/schemas/sitemap/0.9’);

    //Get list of sitemap urls

    var sitemaps = root.getChildren();//sitemap

    //for each sitemap URL

    for (i = 0; i < sitemaps.length; i++) {

      //Get child elements of sitemap element

      var sitemap = sitemaps[i].getChildren();

      //For each child element of sitemap element

      for (a = 0; a < sitemap.length; a++) {

        var element = sitemap[a];

        //Find loc element for sitemap URL

        if (element.getName() === 'loc') {


         // xml = loadXML(element.getText());

          appendRows(xml.getRootElement().getChildren());

        }
      
   else if (root.getName() === 'urlset') {//if sitemap is url sitemap.

    appendRows(root.getChildren());

                   }

                 }

               }

           }

function appendRows(items) {

var urls = [];

var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet(); //to write rows

//var filtered = data.filter(function (row) {

// return row[1].getFullYear() === 2016;

// });

for (var i = 0; i < items.length; i++) {

var children = items[i].getChildren();

var row = [];

for (var a = 0; a < children.length; a++) {

  var child = children[a];

  if (child.getChildren().length === 0) {

    row.push(child.getText());

   // row.filter(items)

  }

}

urls.push(row);

}

//write rows to sheet

sheet.getRange(sheet.getLastRow() + 1, 1, urls.length, urls[0].length).setValues(urls);

}

Create a computed JSON array in JS with multiple variables

First off, apologies if this is normally a simple thing, but I’m not particularly experienced in JS. I’m trying to make some graphs in Plotly.js for a work site that currently holds raw JSON. We have a JSON in the format:

stuff = [{"name": "shark", "location": "somewhere", "number":10},
         {"name": "shark", "location": "somewhereelse", "number":50},
         {"name": "shark", "location": "somewhere", "number":25},
         {"name": "turtle", "location": "anotherplace", "number":1},
         {"name": "elephant", "location": "greatplace", "number":50},
         {"name": "elephant", "location": "greatplace", "number":75}

And I need the result to look like:

computed = [{"name":"shark", "location":"somewhere", "number":35},
            {"name":"shark", "location":"somewhereelse", "number":50},
            {"name":"turtle", "location":"anotherplace", "number":1},
            {"name":"elephant", "location":"greatplace", "number":125}

Where all names are grouped by location and all numbers in that group are summed. It is then this computed JSON that I’ll be using to graph with Plotly.js with some functions I have already built.

I think I can simplify the problem as:

forEach((item) => {
x.push(item['location']
y.push(y += stuff.number where stuff.location === x[-1])
}

But this also means I’ll get the same number of rows as in stuff, just computed and graphed. I’m afraid I can’t figure it out any further.

Any help would be muchly appreciated.

Everytime I test my attributes are undefined?

I want to create a class Deck that gets two attributes id and remaining. I use the Deck of Cards API to get the information of a deck but every time I create a Deck I keep getting id and remaining as undefined and I don’t understand why because the JSON value is good and when I print it I got something but my attributes are undefined.

 class Deck {

    constructor(numberOfDeck, jokersEnabled) {
        let url;

        if (jokersEnabled) {
            url = "https://www.deckofcardsapi.com/api/deck/new/shuffle/?deck_count=" + numberOfDeck + "&jokers_enabled=true";
        } else {
            url = "https://www.deckofcardsapi.com/api/deck/new/shuffle/?deck_count=" + numberOfDeck;
        }
        console.log(url);
        fetch(url).then(res => res.json()).then(value => {
            this.id = value.deck_id;
            this.remaining = value.remaining;
        }).catch(function(err) {
            console.log(err);
        });
    }
}

let deck = new Deck(1, true);
console.log(deck.id + " " + deck.remaining);
