Magento 2.1 Extensions – Where to Create Custom Extensions for Magento 2

extensionsmagento-2.1magento2

Some articles encourage to create custom extensions in app/code and some other encourage to create them under vendor. Are both these two methods fine?

What if I want to override a module in vendor? Do I need to write my custom module also inside vendor folder or app/code?

Do they act as codepools as in Magento 1.x?

Please anyone clarify the purpose of each directories.

You can look at the folders app/code and vendor as the codepools in M1, but they are not really codepools.
There is no "codepool" concept in M1.

vendor folder is for modules you download via composer. You should not write code in that folder.
app/code is your playground. Add your own extensions here.

If you need to rewrite/extend something in the vendor folder you can do it in the app/code folder. Just make sure you specify the soft dependency in the module.xml of your module, in the same way you did it in M1 in app/etc/modules/Namespace_Module.xml file.
The only difference is that in m2 they are not actually dependencies. They are sequences.
This way your module will be loaded after the one from the vendor folder

By Dependency Injection:

protected $cartModel;

public function __construct(
   ...
   Magento\Checkout\Model\Cart $cartModel
   ...
) {
    $this->cartModel = $cartModel;
}


public function afterIsAvailable(\Magento\Payment\Model\Method\AbstractMethod $subject, $result)
{
    $postcode = $this->cartModel->getQuote()->getShippingAddress()->getPostcode();
    $country = $this->cartModel->getQuote()->getShippingAddress()->getCountry();
    $province = $this->cartModel->getQuote()->getShippingAddress()->getRegion();
    $paymentMethodCode = $subject->getCode();

    if ($paymentMethodCode == 'method-code') {
        return $result; //Return result for true scenario. return true wont work
    } else {
        return false;
    }
}

By ObjectManager:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$cart = $objectManager->get('\Magento\Checkout\Model\Cart');
$postcode = $cart->getQuote()->getShippingAddress()->getPostcode();
$country = $cart->getQuote()->getShippingAddress()->getCountry();
$province = $cart->getQuote()->getShippingAddress()->getRegion();
$paymentMethodCode = $subject->getCode();

if ($paymentMethodCode == 'clickcanarias') {
    return $result; //Return result for true scenario. return true wont work
} else {
    return false;
}
