I’m trying to interpret user commands as dash optional flag.

{run -o -f -a file1 file2}

Something like this:

/{run (-o|-f) (w+) (.+?)}/g;

Is very limiting with only 1 choice of flag, how do I let them flag any amount, spit out the flags into groups, and not worry about a set amount of whitespace in between.

string = "{run    -a  file1 file2}"
string = "{run    -a -o -f  file1 file2}"
string = "{run -f-a-o  file1 file2}"

string.match(regex) should output each flag and each file name.

So, basically I want to make an anti-swear system for my bot, I already made a bannedWord.js file in the events.js folder but I want a clear step by step answer on what to do.

Is there any option to share an image via WhatsApp link (ex: https://wa.me/)?

I mean if I have an image-blob, or a data-URL, how can I share it on WhatsApp from a web app?

Thanks

Here is my code. Whenever I play the start button, it spasms out. Any help would be appreciated! I’m wanting to, whenever I press the button, a timer for 1 second to count down based on the truthiness of isPlaying.

const [onBreak, setOnBreak] = useState(false) 
  const [isPlaying, setIsPlaying] = useState(false)

  useEffect(() => {
    const timerFunc = setInterval(() => {
    setIsPlaying(!isPlaying)
    if (!onBreak) {
      if (sessionSec === 0 && sessionMin !== 0) {
        setSessionSec(59)
        setSessionMin(sessionMin - 1)
      } else if (sessionSec !== 0 && sessionMin !== 0)  {
         setSessionSec(sessionSec - 1)
      } else if (sessionSec === 0 && sessionMin === 0) {
        setOnBreak(true)
      }
    } else if (onBreak) {
        if (breakSec === 0 && breakMin !== 0) {
        setBreakSec(59)
        setBreakMin(breakMin - 1)
      } else if (breakSec !== 0 && breakMin !== 0) {
         setBreakSec(breakSec - 1)
      } else if (breakSec === 0 && breakMin === 0) {
        setOnBreak(false)
      }
    } else {
  clearInterval(timerFunc)
  }
  }, 100);
  }, [isPlaying]);

    <button onClick={() => setIsPlaying(!isPlaying)}>{isPlaying ? 'Pause': 'Play'}</button>

So I have made a custom hook for fetching and I’m trying to use that hook and filter some stuff from it using my params. But the fetch returns undefined firstly which actually breaks my code.

Custom Hook code

import axios from "axios";
import { useState, useEffect } from "react"

export const useFetch = (url) => {
    const [loading, setLoading] = useState(false);
    const [data, setData] = useState([]);
    const [error, setError] = useState('')


    const getData = () => {
        setLoading(true)
        try {
            axios.get(url)
                .then(response => {
                    setData(response.data);
                    setLoading(false)
                })
          } catch (error) {
            setError(error)
          }
    };

    useEffect(() => {
        getData()
    }, [url])

    return {loading, data, error}

}

Code where I’m trying to use the fetch

import React, { useEffect, useState } from 'react';
import { useParams } from 'react-router-dom';
import { useFetch } from '../custom_hooks/useFetch';

const PersonDetails = () => {

    const { loading, data , error } = useFetch('https://randomuser.me/api?results=20');
    const { results } = data;
    const { id } = useParams();

    const [person, setPerson] = useState({})

    useEffect(() => { 
        const newPerson = results?.find(person => parseInt(person.login.uuid) === parseInt(id))
        console.log(newPerson)
        setPerson(newPerson)
    }, [])

    return (
        <div>
            Testing
        </div>
    )
}

export default PersonDetails

I am working on a coding assessment and running into a problem when it comes to rendering dummy data from Mirage JS on my page. When I console log the data I’m looking for it shows up fine in the console but I can’t figure out why it’s not rendering on the page.

Here’s the server.js

import { createServer, Model } from "miragejs";
import faker from "faker";
import avatar from "./avatar.png";

export function makeServer({ environment = "test" } = {}) {
  let server = createServer({
    environment,
    models: {
      employee: Model,
    },
    seeds(server) {
      for (let i = 0; i < 10; i++) {
        server.create("employee", {
          id: faker.datatype.uuid(),
          firstName: faker.name.firstName(),
          lastName: faker.name.lastName(),
          email: faker.internet.email(),
          phone: faker.phone.phoneNumber(),
          bio: faker.lorem.paragraph(),
          avatar: avatar,
          address: {
            streetAddress: `${faker.address.streetAddress()} ${faker.address.streetName()}`,
            city: faker.address.city(),
            state: faker.address.stateAbbr(),
            zipCode: faker.address.zipCode(),
          },
        });
      }
    },
    routes() {
      this.namespace = "api";
      this.get(
        "/employees",
        (schema) => {
          return schema.employees.all();
        },
        { timing: 1000 }
      );
      this.patch(
        "/employees/:id",
        (schema, request) => {
          const attrs = JSON.parse(request.requestBody);
          const employee = schema.employees.find(request.params.id);
          employee.update(attrs);
        },
        { timing: 300 }
      );
      this.delete(
        "/employees/:id",
        (schema, request) => {
          const employee = schema.employees.find(request.params.id);
          employee.destroy();
          return new Response();
        },
        { timing: 300 }
      );
    },
  });
  return server;
}

and here’s the app.js

import { makeServer } from "./server";
import { useEffect, useState } from "react";

if (process.env.NODE_ENV === "development") {
  makeServer({ environment: "development" });
}

function App() {
  const [employees, setEmployees] = useState([])

  useEffect(() => {
    fetch('/api/employees')
    .then(res => res.json())
    .then(json => setEmployees(json.employees)
    )
  }, [])
  return (
    <div>
      <header>
        <h1>Employees</h1>
      </header>
      {employees.length > 0 ? (
        <table>
          <thead>
            <tr>
              <th>id</th>
              <th>first name</th>
              <th>last name</th>
            </tr>
          </thead>
          <tbody>
            {employees.map(({id, firstName, lastName}) => {
              <tr key={id}>
                <td>{id}</td>
                <td>{firstName}</td>
                <td>{lastName}</td>
              </tr>
          console.log(firstName)
            })}
          </tbody>
        </table>
      ) : (
        <p>No employees</p>
        )}
  </div>
  );
}
export default App;

I am loading data card and when I press pagination buttons, the data changes but screen remains in the same place. How do I scroll to top when button is pressed? The application is a SPA so maybe that is causing the issue?

Having this clsx method which works fine:

const getLinkClasses = (disabled: boolean) => {
  return clsx('flex whitespace-nowrap', {
    'text-gray-500': !disabled,
    'text-gray-300 cursor-not-allowed': disabled
  });
};

There are two other optional variables, one for disabled and one for !disabled that are strings and can add new rules to the above method. Let’s call them disabledValue and notDisabledValue.

For example,

const disabledValue = 'bg-red-100'; 
const notDisabledValue = 'bg-green-100';

In order to add those variables, I’ve made the following changes:

export interface MyProps {
  disabledValue?: string;
  notDisabledValue?: string;
}

const getLinkClasses = (disabled: boolean, style: MyProps) => {
  const notDis = `text-gray-500 ${style.notDisabledValue ?? ''}`;
  const dis = `text-gray-300 cursor-not-allowed ${style.disabledValue ?? ''}`;

  return clsx('flex whitespace-nowrap', {
    notDis: !disabled,
    dis: disabled
  });
};

The problem is that those two variables, notDis and dis aren’t read:

‘notDis’ is declared but its value is never read.ts(6133)

‘notDis’ is assigned a value but never
used.eslint@typescript-eslint/no-unused-vars

Is there a way to fix it?

I would like to send Javascript array containing files to PHP using AJAX

The following are 3 files that I want to send to the php side. (These outputs come from console.log(document.getElementById("id").files[0]);

File { name: "img1.svg", lastModified: 1641853737982, webkitRelativePath: "", size: 2506, type: "image/svg+xml" }
File { name: "img2.svg", lastModified: 1641853677323, webkitRelativePath: "", size: 1060, type: "image/svg+xml" }
File { name: "img3.svg", lastModified: 1641853656789, webkitRelativePath: "", size: 1845, type: "image/svg+xml" }

In this case there are 3 files (There can be more or less than that).

The 3 files are in a variable arrFiles.
So console.log(arrFiles) outputs:
Array [ File, File, File]

JQuery file

var form_data = new FormData();
var arrFiles = JSON.stringify(arrFiles)
form_data.append("imgs", arrFiles);

$.ajax({
    url:url,
    method:"POST",
    data: form_data,
    contentType: false,
    cache: false,
    processData: false,
    success:function(data)
    {
        alert(data);
    }
}); 

php file

if(isset($_POST["imgs"])){
    //Would like to handle each image separately.
    $imgs = json_decode($_POST['imgs']);


    //May be something like :
    foreach($_POST["imgs"] as $img){
        $movePath = "images/".$img['name'];
        move_uploaded_file($img["tmp_name"], $movePath);
    }
    return;
}

Is there a way to handle this ?

I am trying to implement a function that allows users to input any URL they would like to their home screen on my website.

Is there a proper way to sanitize URL links before inserting to a database?

Thank you in advance!

I’m trying to filter out objects based on whether ALL the given search terms exist in SOME of the property values of EACH object in the array.
But I also don’t want to search within the deviceId property.

But is there a way to do it with less code?

So I do the following:

1. Convert the objects into iterable arrays
2. Filter out the array to remove arrays withdeviceId
3. Convert the arrays back into the Key/Value pair objects

let DeviceDtoArrayOfArray = [];

DeviceDtos.forEach((indiv) => {
  DeviceDtoArrayOfArray.push(Object.entries(indiv));
});
let DeviceDtoArrayOfArrayFiltered = [];
DeviceDtoArrayOfArray.forEach((indiv) =>
  DeviceDtoArrayOfArrayFiltered.push(
    indiv.filter((indiv) => indiv[0] !== "deviceId")
  )
);

let DeviceDtoArrayOfArrayFilteredObjects = [];

DeviceDtoArrayOfArrayFiltered.forEach((indiv) => {
  DeviceDtoArrayOfArrayFilteredObjects.push(Object.fromEntries(indiv));
});

4. Define sample search term array
5. For each object from Step 3, create an array of it’s property values
6. Filter each Object in the array by searching each Search Term, check to see if it exists within some of the property values from Step 5, if it exists, then the object is returned to a new array, if not, it’s filtered out

Sample Array containing the objects with deviceId

const DeviceDtos = [
  {
    deviceId: 1,
    deviceName: "Device0000",
    hwModelName: "Unassigned",
    deviceTypeName: "Unassigned",
    serviceTag: "A1A"
  },...

Sample Search Terms

const searchTerms = ["HwModel", "A1A"];

Filter out objects based on Search Terms

const results = DeviceDtoArrayOfArrayFilteredObjects.filter((indiv) => {
  const propertiesValues = Object.values(indiv); // all property values

  return searchTerms.every((term) =>
    propertiesValues.some(
      (property) => property.toLowerCase().indexOf(term.toLowerCase()) > -1
    )
  );
});

console.log(results);

I am using JavaScript to automate sending emails on my website, with SMTP and a gmail email address however the emails are sent directly to the receivers spam folder. Is there a way around this?

Here is my code:

   function sendEmail() {

      Email.send({
        Host: "smtp.gmail.com",
        Username: "[email protected]",
        Password: "pass",
        To: document.getElementById('email').value,
        From: "[email protected]",
        Subject: "Subject",
        Body: "hooray",
      })
        .then(function (message) {
          alert("mail sent successfully")
        });
    }

Right now I have something like

const route = '/Images/Banner/'
const slides = [
  {
      name: "banner-01",
      url: `${route}banner-01.png`
  },
  {
      name: "banner-02",
      url: `${route}banner-02.png`
 
  },
  {
      name: "banner-03",
      url: `${route}banner-03.png`
  },
]
]

In this, I’m manually adding each image and it’s properties because there are only 3 images, but i want to dynamically add them based on the quantity of images with the same name (they’ll always are going to be named banner-NN).

Is there an efficient way to iterate through images with the same pattern of name (‘banner-‘) and place them in an array of objects?
