Question:

how can I go about creating a subtraction between the two fields?

I create an library for my REST API and want to send for my customers to use it, but before it I want to create an API KEY (which must be generated in main app) which must be pass to my library in the main class constructor. And right now i have a question, what is the best way to generate API KEY? Right now i create this key as JWT like below:

return jwt.sign(payload, "SECRET KEY");

but JWT is very very long, and I want to create key which will be much shorter that JWT. How is the best approach to generate KEYS? How for example Github generate API KEY for his REST API?

thanks for any help!

I’m using quite a new technology called Astro (https://astro.build/) to build a completely static, server side rendered page, shipping zero JS.

I have a page with a form that is a simple text input, when the user fills this in and clicks the submit button, it sends a GET request to an astro page. The url will look something like this ….

/?search=1234

What I want to be able to do is get access to that querystring parameter in order to redirect my user to another static page /1234.

I am trying to access the quesrystring parameter with Astro.request, but the object, including the parameters attribute is completely empty.

Is there anyway to access the querystring parameters from a .astro page/file?

I have 2 js files:
utils.js:

class ElementPart
{
    constructor(text)
    {
        this.text = text;
    }
}

elem.js

const btn = document.querySelector('.elem_btn');

btn.addEventListener("click", () =>
{
    const p = new ElementPart("aaaa");
    console.log(p);
})

When I load the page I get the following error:

Uncaught SyntaxError: Unexpected identifier utils.js:1

And when I click on the button:

Uncaught ReferenceError: ElementPart is not defined
    at HTMLButtonElement.<anonymous> (elem.js:5)
(anonymous) @ elem.js:5

I load the files on the html file like this:

 <script src="/utils.js"></script>
 <script src="/createelem.js"></script>

When the user click on the photo is downloading the original photo ,
but what i want is;when the user clicks on download it should be downloaded on for example 400×400 resoulution.

<a href="images/<?php echo $row['image_name'] ?>" 
class="ms-5" download><i class="bi bi-download" 
style="color: black; font-size:20px"></i></a>

I currently have the following code:

const renderModal = location.state?.modal ?? isModal ?? false;

const FormComponent = renderModal ? FormModal : Default;

which checks if renderAsModal is true & then returns the Modal component if so (if not, default component)

But now I have another possible modal, which I can check for like so:

const renderCustomModal: boolean =
   location.state?.modal ?? isModal ?? form.key === "UniqueKey" ?? false;

How can I update my FormComponent assignment to check for renderCustomModal as well so my CustomModal can be included in the 3 React components that can be returned? Any helpful links/ best practises would be really appreciated.

I was trying to do the burger menu and faced some kind of ‘bug’. Burger menu shows up at width less than 780px and when ever it reaches that point all works good exept one thing.

Property transform:translate triggers every time you reach needed width and menu goes back on initial place. Hard to explain, just check the snippet and resize the width. Any suggestions?

let burgerBtn = document.querySelector(".menu_burger");
let menu = document.querySelector(".list");

burgerBtn.addEventListener('click', function() {
    burgerBtn.classList.toggle('active');
    menu.classList.toggle('active');
});

This is the function


import { FormikHelpers } from 'formik';
import { v4 as uuid } from 'uuid';

import { Option } from '@pro4all/shared/ui';

export function splitAndAddToValues(
  name: string,
  value: string,
  currentRecipients?: Option[],
  setFieldValue?: FormikHelpers<unknown>['setFieldValue'],
  setFieldTouched?: FormikHelpers<unknown>['setFieldTouched']
) {
  if (!/[ ,;]/.test(value)) return;

  // Return true if address already exists in field
  const findDuplicate = (address: string) =>
    currentRecipients.find((recipient) => recipient.inputValue === address);

  // Remove duplicates from pasted text
  const toUniqueArray = (addresses: string[]) => [...new Set(addresses)];

  // Pasted text is parsed as addresses delimited by whitespace, semi colon or comma
  const uniqueAddresses = toUniqueArray(
    value
      ?.split(/[s;,]+/)
      .filter(Boolean)
      .filter((address) => !findDuplicate(address))
  );

  const nextRecipients: Option[] = uniqueAddresses.map((address) => ({
    id: uuid(),
    inputValue: address,
    label: address,
  }));

  // Force the state updates to the form/components to the end of the browser's
  // event loop.
  setTimeout(() => {
    // As long as we setValue() in a timed callback, the change triggered in the input will hide and clear autocomplete
    setFieldValue(name, [...currentRecipients, ...nextRecipients]);

    // Touch to trigger validation
    setFieldTouched(name);
  }, 0);
}

And this is the basic test.

import { splitAndAddToValues } from './splitAndAddToValues';

    const name = 'admins';
    const singleValue = '[email protected]';
    const multipleValues = '[email protected] [email protected]';
    test('Return one value if there is no comma, semicolon or space', () => {
    expect(splitAndAddToValues(name, singleValue)).toHaveLength(2);
});

The problem is that if i call my fn with one value it returns undefined.
And if i call it with 2 values it tells me that the param address is not recognized, but the value is called below…
i don’t know if it is a hoisting problem
or a setTimeOut problem…i am kind of lost here

I’m starting learning Webpack.

In the teachers code in the file index.js that Webpack creates its something like:

var {initializeButtons} = require('./mainfile.js');

initializeButtons();

Can someone explain why {initializeButtons} is a variable there?

Thank you so much 🙂

I have the following function which creates a notification:

displayNotification(title: string, msg: string, avatarUrl: string, room: Room) {
    const notifBody = {
        body: msg,
    };
    if (avatarUrl) notifBody['icon'] = avatarUrl;
    const notification = new window.Notification(title, notifBody);

    notification.onclick = function() {
        dis.dispatch({
            action: 'view_room',
            room_id: room.roomId,
        });
        window.focus();
        notification.close();
    };

    return notification;
}

As you can see, when I’m creating the notification I pass a title and body to it. The title contains Bozhidar3 and the body contains Test Message so I expect the notification to only have these 2 fields alongside an icon. What actually happens is that I see this:

I can see my localhost wrapped around <a></a> tag and I have no idea where is it coming from. I went through all the notification instance properties here – https://developer.mozilla.org/en-US/docs/Web/API/notification but I couldn’t figure out what might this be. Does anyone have an educated guess where this might be coming from?I’m using Chrome on Linux.

I’m building a web ar app that allows users to wear GLTF head models. (https://www.head5.camera/) In order to get the correct lighting on the GLTF, I have set renderer.outputEncoding = THREE.sRGBEncoding and this works great BUT it also adjusts the lighting of my THREE.VideoTexture from my video stream. Is there a way to encode just the GLTF but preserve the LinearEncoding? of the rest of the scene. Any help is much appreciated.

Here’s an example of what I mean:

The background is lighter than it is supposed to be because it is also being encoded.

I have a index.html + javascript code in the ‘assets’ folder of my apk. When the app is launched, I open index.html in a webview ; the html page is displayed properly and the basic javascript code is also properly executed.

To open index.html in my webview, I use the following code:

webView.loadUrl("https://appassets.androidplatform.net/assets/www/examples/index.html");

At runtime, a .txt file is created by the app and placed on the disk of my Android phone at:

file:///storage/emulated/0/Android/data/com.example.test/files/www/mytextfile.txt

Now, I have a button in my index.html page. When I click on this button, I want to execute a javascript function that will process some tasks on mytextfile.txt and display it on my html page in the webview.

So I execute in javascript something like this when the user clicks on the button:

doStuffOnDiskTxtFile('file:///storage/emulated/0/Android/data/com.example.test/files/www/mytextfile.txt')

But I get the following error:

    "Fetch API cannot load file:///storage/emulated/0/Android/data/com.example.test/files/www/mytextfile.txt. 
URL scheme "file" is not supported.", 
source: https://appassets.androidplatform.net/assets/www/build/module.js

Any idea how to solve this issue ? Would it work better if my html + javascript code were hosted on a distant server and not ran locally ?

Thanks for your help.
