Create event and observer for customer sign up (Magento 2)

Question

How can I create my own event and observer for customer sign up, From this link,

Magento2 : customer_account_create event is not triggering

I found that We can use customer_register_success for customer register success.

So I found that events.xml in /module-persistent/etc/webapi_rest/events.xml

<event name="customer_register_success">
    <observer name="persistent" instance="Magento\Persistent\Observer\RemovePersistentCookieOnRegisterObserver" />
</event>

So observer file is RemovePersistentCookieOnRegisterObserver.php I want to make my custom event and observer for customer sign up, how to achieve that and where should I write my custom events and observer.

This is my code

 namespace YX\Customer\Observer

 class RegisterSuccess implements \Magento\Framework\Event\ObserverInterface
{

protected  $customlogger;
protected  $tempblock;
protected  $customerHelper;


public function __construct(
    \Rage\Base\Helper\CustomLogger $loggerHelper
     \YX\Catalog\Block\OrderHelper $orderHelper,
    \YX\Customer\Helper\CustomerHelper $customerHelper

)
{
    $this->customlogger = $loggerHelper->getLogger('custom');
    $this->tempblock = $this->getLayout()->createBlock('YX\Catalog\Block\OrderHelper');
    $this->customerHelper = $this->helper('YX\Customer\Helper\CustomerHelper');
}
public function execute(
    \Magento\Framework\Event\Observer $observer
) {

 \Magento\Framework\App\ObjectManager::getInstance()
        ->get(\Psr\Log\LoggerInterface::class)->debug("here in customer 
 login before func " .$this->customerHelper->isCustomer());

    if (!($this->customerHelper->isCustomer())){
        $customerID = $this->customerHelper->getCustomerId();
        $orderId = $this->customerHelper->getOrderId();
        $this->tempblock->guestToCustomer($orderId,$customerID);

    }
}

}

I have put dubgger logs but still, on the user sign up it doesn't go inside execute() function

Try this,

Create this file in the path app/code/vendor/module/etc/events.xml For example ,

<?xml version="1.0" ?><config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
<event name="customer_register_success">
    <observer instance="vendor\modulename\Observer\Customer\RegisterSuccess" name="customer_register_succes"/>
</event>

then

Place the respective observer file in the folder defined like app/code/vendor/module/Observer/Customer/RegisterSuccess.php

<?php                                                         
 namespace vendor\module\Observer\Customer;                        
 class RegisterSuccess implements \Magento\Framework\Event\ObserverInterface                                
 {

public function __construct(
    ......
    ......
    )
{
    ......
}
public function execute(
    \Magento\Framework\Event\Observer $observer
) {

    $customer = $observer->getEvent()->getData('customer');

}}

hope this helps.
