How to declare a global variable and access it in all the other modules in ReactJS?



Being new to ReactJS, I wanted help with the global variable declaration and usage. The scenario is that I have different modules and I want to access a variable which is available in all the modules, irrespective of their relations. To be precise, I have an admin panel and a user dashboard which have no common parent. But, I wish to set a value of a variable in admin panel and use that value in user dashboard and other modules. I tried looking out for solutions but couldn't get a feasible solution. It would be a great help if the solution is explained using an example.





This is a JavaScript question, not a React question. Which module system are you using?

@JonasLochmann I wanted information if there is a concept like Global Variable declaration and accessing it through modules in ReactJS, just like JavaScript

Not sure about your exact use-case and what is most suitable for you, but there are several patterns more suitable to concepts of react, that provide an ability to use shared variable in different components:



Making a parent for both the components and passing states between them solved my problem. For my use case, I defined the Admin Home Page Component (where the state was set) and User Login Component (where I had to access the state) into a common Parent Component and defined this Parent Component into App (where all the other components were defined). This solved my issue of accessing the state of the component and providing it to another component which had no common relationship.

PHP contact form sending but not receiving emails

PHP contact form sending but not receiving emails I have created a contact form using PHP to send the data. The form seems to send fine as there are no errors and success message appears, however I am not receving the emails into the designated inbox. I am using PHPMailer as I originally tried just using the php 'mail' command which I now understand is a bit hit and miss. I cannot see why I would not be receving the emails so I would be very grateful for any help that could be given. I'm quite new to PHP so please be patient with me :) <?php use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; $msg = ""; if (isset($_POST['submit'])) { require 'phpmailer/src/Exception.php'; require 'phpmailer/src/PHPMailer.php'; require 'phpmailer/src/SMTP.php'; function sendemail ($to, $from, $body) { $mail = new PHPMailer(true); $mail->setFrom($from); $mail->addAddress($to); $ma...

Do graphics cards have individual ID by which single devices can be distinguished?

Do graphics cards have individual ID by which single devices can be distinguished? I have several graphics cards of the same manufacturer and same model and I want to distinguish them not only by the pcie socket they reside in but by some individual value I can read from the hardware. Is there such value and if so what would it be called and how could I access it? Right now I'm using modern nvidia cards (10xx series) and nvidia inspector.but I'd prefer if there was any value that was also applicable to amd. I have programming and scripting knowledge. I am running Windows 10 1 Answer 1 This is a powershell example to pull information from video cards. The DeviceID is supposed to be unique but only if the manufacturer supports Windows Display Driver Model (WDDM). (I copied this directly from docs.microsoft.com) $strComputer = "." $colItems = get-wmiobject -class "Win32_VideoC...
