JS-Cookie not being able to be set due to “HTTPONLY cookie already exists”

Next.js v12.0.7
NodeJS v14.17.4

I’m trying to create change my authentication from localstorage to a httponly cookie. I’ve chosen to use js-cookie for this but for some reason I just can’t create a cookie with the httponly parameter. I’m using this code below to set the cookie:

Cookies.set('authtoken', 'test', {
     path: '/',
     expires: 7,
     sameSite: 'strict',
     httpOnly: true
});

If I remove the httponly then the cookie would be set.. If I keep the httponly I get an error saying:

Cookie “authtoken” has been rejected because there is already an HTTP-Only cookie but script tried to store a new one.

I use Mozilla Firefox as my browser and I’ve tried changing the browser to see if something is up with the browser. Chrome does not state any errors in console but cookie also would not be set with httponly but without, no problemos.

Just in case it could be the value, my value consists of an base64 encoded jwt token. Could this break it?

Do we have any cookie experts out there who could assist, preferably not Santa. I’ve also done a short GIF to show my issue:

I’m going to keep trying. Was just hoping someone could end my suffering 😉

check date existence on array of string

This is my dataset from MongoDB Collection:


{
  "_id": "60c0ace96e93993880efd337",
  "lv": [
   uid: 1,
   "createdate": "2021-12-15T12:30:01.935Z",
   "updatedAt": [
      "2021-12-15T12:31:11.635Z",
      "2021-12-15T12:31:51.955Z",
      "2021-12-16T12:30:01.935Z",
      "2021-12-16T12:30:01.935Z",
      "2021-12-17T12:30:01.935Z",
      "2021-12-18T12:30:01.935Z"
   ]
  ]
},
{
...
}

I want to filterout only the data which date range lies in createdate column or updatedAt column.

I am not able to get the desired result. Not getting the idea that where I am making the mistake in the query or coed.

What I have tried I will mention here.

let startA = new Date("2021-12-14");
const a = new Date(startA.setHours(startA.getHours() - 5));
const start = new Date(a.setMinutes(startA.getMinutes() - 30));

let endA = new Date("2021-12-17");
const b = new Date(endA.setHours(endA.getHours() - 5));
const end = new Date(b.setMinutes(endA.getMinutes() - 30));

const fetchData = await MyCollection.findOne(
  { 
    _id: ObjectId(req.body.id),
    'lv.createdate': { $gte: start, $lt: end },
    'lv.updatedAt': {
      $elemMatch: { $gte: start, $lt: end }
    }
  }
).lean().exec();

Any help or suggestion is really appreciated. Thanks in advance for the interaction.

Got an error “cannot read properties” in my game code

I am working on a simple game project on my studies, still not too good at it. I’ve tried to implement an “if-statement” that limited my game character movements inside the canyon so it could not go through the walls and find itself underground. I thought that it looks pretty good and functional but I still get information in the console that properties x_pos are undefined in line 160. Can someone smarter show me where is my problem? I suppose that I should somehow recall properties inside the if-statement but as far I’ve tried I just ruined everything and made it messier than this is now.

React script is found but it won’t render the simple hello world element

I’m new to react and i’m just testing out a simple render at the moment. I get no errors in the browser but nothing shows up on my screen that appears in my javascript react file.

html

<html>
    <head>
         <script  type="text/babel" src="reactfile.js"> testing</script>

<link rel="stylesheet" href="/styles.css">

How to implement this method in Ruby? or is there third party lib to do this?

I have this ts function:

import { keccak_256 } from "js-sha3";
import { Buffer } from "buffer/";


export function getNamehash(name: string) {
  let node = "0000000000000000000000000000000000000000000000000000000000000000";

  if (name) {
    let labels = name.split(".");

    for (let i = labels.length - 1; i >= 0; i--) {
      let labelSha = keccak_256(labels[i]);
      node = keccak_256(Buffer.from(node + labelSha, "hex"));
    }   
  }

  return "0x" + node;
}

and when calling this method, it gives results like:

getNamehash("a")
// "0xc3025f6c23b9ab4d91adbcccf350072ec880c65db9a3f42e802fe4ceed56e728"

getNamehash("a.b")

How do I ensure that my media query sidebar nav closes without affect my main nav menu

In my max-width:320px media query I have a sidebar navigation as oppose to the regular normal bar that is in the other max-width’s. now the problem I’m experiencing is that every time I close my sidebar nav in max-width:320px. the regular menu in the largest width:1440px is removed because the browser’s element style is set to “display:none”. How do I get around this, close my sidebar nav without removing main nav in the other width?

    switch (block.type) {
      case "header":

        break;

        break;
      case "delimiter":
        convertedHtml += "<hr />";
        break;
      case "image":
        convertedHtml += `<img class="img-fluid" src="${block.data.file.url}" title="${block.data.caption}" /><br /><em>${block.data.caption}</em>`;

      default:
        console.log("Unknown block type", block.type);
        break;
    }
  });
  return convertedHtml;

}

Then I have no idea how to convert html tag to styled html.

var parser = new DOMParser();
var msg = parser.parseFromString(msg, 'text/html');

I have tried this, but it comes [object HTMLDocument]

I want to zoom image but inside the div

I want to zoom the image inside the div but when I am trying to zoom the image the size of the div is also increasing.

<img src="" alt="Image Preview" id="zoom" class="image-preview__image">

   <div class="btn-group mt-2" role="group" aria-label="">
            <button ng-click="Size=100" class="btn btn-sm btn-group btn-outline-info" onclick="zoomout()" >100%</button>
            <button ng-click="Size=200"  class="btn btn-sm btn-group btn-outline-info"  onclick="zoomin()" >200%</button>
            <button ng-click="Size=300" class="btn btn-sm btn-group btn-outline-info">300%</button>
            <button ng-click="Size=400" class="btn btn-sm btn-group btn-outline-info">400%</button>
            </div>

    <script type="text/javascript">

   function zoomin() {
        var GFG = document.getElementById("zoom");
        var currHeight = GFG.clientHeight;
            GFG.style.height = (currHeight + 40) + "px";
    }
    function zoomout() {
        var GFG = document.getElementById("zoom");
        var currHeight = GFG.clientHeight;
            GFG.style.height = (currHeight - 40) + "px";
    }

Mirroring or clonning a div to another div

I was trying to mirror/clone a div into another div but I couldn’t find any solutions to this online. What I mean by clone is replicate everything live from one div to another. An example of this is when you hover on icons in your taskbar on Windows OS it shows you what is happening on that specific GUI. How can I achieve this? If there are no ways of live cloning , screenshotting that specific div and showing it on a separate div would be fine. One important thing to keep in mind is that the div to be cloned could contain elements like Images, text, videos, Iframes, etc… Any help on this or a nudge in the right direction is much appreciated. Thanks in advance.

//Things I tried 

let div =
  document.getElementById('testDiv');

html2canvas(div).then(
  function(canvas) {
    document
      .getElementById('#testDivClone')
      .appendChild(canvas);
  })

Using eslint with javascript- Unable to resolve path to module

I was having this problem!

enter image description here

The reference exists and it works, the problem is that eslint cannot find it. I fix it as follows!

.eslintrc.json

I assume eslint installed and has problems integrating express node and react js projects

You can use the automatic configuration of eslint follow the steps and when it is installed configure your .eslint file add the description of setting

"settings": {
"import/resolver": {
  "node": {
    "extensions": [".js", ".jsx"],
    "moduleDirectory": ["node_modules", "src/"]
  }
}

}
