I am facing some issues using findOrCreate together with sequelize. I tried to apply the code bellow in order to catch sequelize errors and make sure the user transaction works.

const { User } = require('../models/user');
const { ValidationError, Sequelize } = require('sequelize');
const { getSequelizeErrorObject } = require('../utils/functions');

const registerController = async (req, res) => {
  const queryCondition = {
    where: Sequelize.or(
      { username: req.body.username },
      { email: req.body.email },
    ),
    defaults: {
      username: req.body.username,
      email: req.body.email,
      password: req.body.password,
    },
  };

  const [user, userCreated] = await User.findOrCreate(queryCondition).catch(
    (err) => {
      if (err instanceof ValidationError) {
        const sequelizeError = getSequelizeErrorObject(err);
        return res.status(400).send(sequelizeError);
      }

      return res.status(500).send({
        message: 'Something went wrong when trying to process the request',
      });
    },
  );

  if (userCreated) {
    const { username, email, id } = user;
    return res.status(200).json({ username, email, id });
  }

  return res.status(400).send({
    message:
      'The email/username are already associated within the app, try to sign in instead',
  });
};

module.exports = registerController;

I am getting this error:

TypeError: (intermediate value) is not iterable
    at registerController (C:UsersfilipDesktopProjectselfmetterservercontrollersregisterController.js:18:31)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

It just happens if I send this kind of data (that hits the sequelize validation):

"email": "",
"password": "m",
"username": ""

Tried to also use the promise chain (.then, .catch) but would like to avoid that if possible.

also tried to add a try catch block around the whole thing, but the error was the following:

Error: Can’t set headers after they are sent to the client

Any help with this? (The docs are not very clear on how to handle things with sequelize)

Thanks a lot, appreciated!

I have long text for each item but I want to set substring the value for the text while loading the select dropdown.

I tried this but not working.

  <select class="form-control chosen-select" id="eventCode" name="eventCode" >
  @foreach (var item in ViewBag.Events)
  {
      <option value="getEventCode(@item)">@item</option>
  }

script

 <script type="text/javascript">
    
function getEventCode(eventCodeStr) {

    let eventCode = eventCodeStr.substring(0, eventCodeStr.indexOf("("));
    alet(eventCode);
    return eventCode;
}
</script>

text example is this 18AA10 (Smarter Well Integrity 5/7/2018) and I need to get value 18AA10. How to do this?

I am using dreamland.js to write a simple application. I expect the text in the “preview” section to update when I set the value in state, but it’s not updating despite the value clearly being changed. Code is below

import "dreamland/dev";

let state = stateful({
    currentText: ""
})

function Editor() {
  return (
    <div id="editor">
      <textarea
        value={state.currentText}
        on:input={(e: InputEvent) => {
          state.currentText = e.target!.value
          console.log(state.currentText)
        }}
        autofocus
      />
      <div id="preview">
        {state.currentText}
      </div>
    </div>
  )
}

function MainApp() {
  return (
    <div id="app">
      <Editor />
    </div>
  )
}

window.addEventListener('load', () => {
  document.body.appendChild(<MainApp />)
})

does anyone know a script preferably Tampermonkey script which check people who see your story and if a specific person sees it to sent you a notification? Is that even possible? I have tried to do this but for me with my lack of knowledge on js I couldn’t manage to even get if the person saw it and then to even get a notification.

I am using:

console.log('Instagram Story Notifier script loaded');

(function() {
  'use strict';
  const targetUsers = ['usr1', 'usr2', 'usr3']; // Add the usernames you want to monitor
  const notificationMessage = 'Someone viewed your story';

  const observer = new MutationObserver(() => {
    const storyViewsContainer = document.querySelector('div[role="dialog"] ul li');
    if (storyViewsContainer) {
      console.log('Story views container found!');
      checkStoryViews();
      observer.disconnect(); // stop observing
    }
  });

  observer.observe(document.body, {
    childList: true,
    subtree: true
  });

  function checkStoryViews() {
    console.log('Checking story views...');
    const viewers = Array.prototype.slice.call(storyViewsContainer.children);
    const viewerUsernames = viewers.map(viewer => viewer.querySelector('span').textContent);
    console.log('Viewers:', viewerUsernames);

    targetUsers.forEach(targetUser => {
      if (viewerUsernames.includes(targetUser)) {
        console.log(`Target user ${targetUser} found`);
        notify(targetUser);
      } else {
        console.log(`Target user ${targetUser} not found`);
      }
    });
  }

  function notify(username) {
    alert(`${username} viewed your story`);
  }
})();

I need the @revolut/checkout npm package as a minified js single file to use it in my ASP.net website, somehow I can not find any CDN or a download link, that’s why I want to build it in node.

When I tried importing razorpay module in above code then it is throwing below error:

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
– add a fallback ‘resolve.fallback: { “url”: require.resolve(“url/”) }’
– install ‘url’
If you don’t want to include a polyfill, you can use an empty module like this:
resolve.fallback: { “url”: false }

am using shadcn Form that uses react hook form, zod for validation and react dropzone together to validate my input before i submit a form.

below is the schema am using and how am mounting the component:

in The Validations

import { z } from "zod";
export const myFormSchema = z.object({
   images: z
    .custom<File>(),
  title: z.string(),
});

and here is my dropzone component

import { FileWithPath, useDropzone } from "react-dropzone";
import { useState, useCallback } from "react";
import Image from "next/image";
import { Upload } from "lucide-react";

type FileUploaderProps = {
  fieldChange: (FILES: File[]) => void;
  mediaUrl: string[] | null;
};

const FileUploader = ({ fieldChange, mediaUrl }: FileUploaderProps) => {
  const [fileUrl, setFileUrl] = useState<string[] | null>(mediaUrl);

  const onDrop = useCallback(
    (acceptedFiles: FileWithPath[]) => {
      fieldChange(acceptedFiles);
      const urls = acceptedFiles.map((file) => URL.createObjectURL(file));
      setFileUrl(urls);
    },
    [fieldChange],
  );
  const { getRootProps, getInputProps } = useDropzone({
    onDrop,
    accept: {
      "image/*": [".png", ".jpeg", ".jpg", ".svg"],
    },
  });

  return (
    <div
      {...getRootProps()}
      className="flex-center bg-dark-3 flex cursor-pointer flex-col rounded-xl"
    >
      <input {...getInputProps()} className="cursor-pointer" />
      {fileUrl ? (
        <>
          <div className="grid grid-cols-3 gap-2">
            {fileUrl.map((image, index) => (
              <button key={index}>
                <Image
                  alt="Product image"
                  className="aspect-square w-full rounded-md object-cover"
                  height="84"
                  src={image}
                  width="84"
                />
              </button>
            ))}
          </div>
          <p className="mt-10 text-center">Click or drag photo to replace</p>
        </>
      ) : (

          <button className="flex aspect-square w-full items-center justify-center rounded-md border border-dashed shadow">
            <Upload className="h-4 w-4 text-muted-foreground" />
            <span className="sr-only">Upload</span>
          </button>
        </div>
      )}
    </div>
  );
};

export default FileUploader;

here is my Form Component that connects them all here am using shadcn ui form to validate that the dropzone is not empty and it must show error if user tries to submit it without selecting images but the validations are not working:

I’m trying to update my electron app on windows with electron-updater.

It all works except when the updater is running, it first asks the users where does he want to install the software and if the install is meant to be per machine or per user.

I do want these questions to be asked when running the installer for the first time, so my electron-builder.json nsis field look like this:

"build": {
        "appId": "com.shuv.oniyama",
        "productName": "Oniyama",
        "directories": {
            "output": "dist"
        },
        "win": {
            "target": [
                "nsis"
            ],
            "icon": "./src/logo/logo.ico"
        },
        "nsis": {
            "oneClick": false,
            "allowToChangeInstallationDirectory": true,
            "installerIcon": "./src/logo/logo.ico",
            "uninstallerIcon": "./src/logo/logo.ico",
            "createDesktopShortcut": true,
            "createStartMenuShortcut": true,
            "shortcutName": "Oniyama"
        }
    }

But I definitely don’t want them when it’s about updating, the app should detect it has already been installed and not ask anything.

Is there any way to achieve this? (preferably other than having two separate installers, one for the updates and one for the installations)

autoUpdater.autoInstallOnAppQuit = true;

i want to use this and not just the quitAndInstall() method

Above is the code I have written to create an access a JSON array, however, when I run the console.log() command I get the following error:

I’m new at programming. I’ve been tasked to develop a website as a final requirements for my database management class. Now i wanna try doing this multi-step form in my website and yes it might be an unnecessary problem but its the one I’m going with.

My problem is:
I am creating something like the Twitch Donation System where Users buy Credits and pay other with the Credits. The Person who gets paid with the credits should be able to transfer the credits to Dollars and send them to the person’s bank account.

I searched though the Stripe API but I only found how the Owner can cash out the money that the users spend and not how the users can cash out the money. Please let me know how this works or if this is even legal or if I should use another API.

Is it required to do a batch update? The “emails” collection will not update. If I do a console.log, it does know what the uid and email are. It also knows there is one record in the “emails” collection. It also updates the “users” collection.

I tried making a second db reference as db2, which did not work.

If I put the “users” update above the “emails” update, the “users” updates but “emails” does not. If I put “emails” above “users”, neither update because “emails” fails to update.

async function setupNewUserInFirestore2(uid, email) {
  try {  

    let date = new Date('2000-01-01T12:00:00');
    const timestamp = date.getTime();
    const unixTimestamp = timestamp / 1000;

    const usersRef = collection(db, "users");
    await setDoc(doc(usersRef, uid), {
      usernameLastUpdated: unixTimestamp, 
      xVerEmailSent: 1

Yesterday I asked if it was necessary to check for duplicate emails when using “verifyBeforeUpdateEmail” and someone commented saying the question wasn’t clear. It was very clear and the answer to that one is YES you do because Google won’t send the email if it’s a dupicate and they don’t bother to give you an error because of it. And that’s why I’m working on this today.

I am trying to create a button where every time you click, a new sentence generates from a list. What I have now is only generating a new sentence when I refresh the page and I’m not sure what to try. I only started learning yesterday so be nice to me please.

Here is what I have so far.

<div>
    <button onclick="button" id="myButton">Hit me.</button>
    <p id="randomQuote"> </p>
</div>

<script>

    var quote = ["S1","S2","S3","S4",  ];

    var randomQuote = Math.floor(Math.random() * quote.length);
    document.getElementById("randomQuote").innerHTML = quote[randomQuote];

</script>
