Magento 2 : specific product remove from quote

Question

I set product's expire time in my custom module. When, product is expire at that time that specific product should be remove from quote. I used event layout_load_before for that.

Because, this code should be working from any page in whole site. If, any other event should i should then, please inform me that also.

Actual Result :

Now, point is that if I remove specific product from quote. Then, product will be remove but minicart is not update.

Expected Result :

When product remove from cart/quote then minicart also refresh and product should be remove from quote/cart.

How to do that ? Please help me.

My observer code :

$items = $this->_checkoutSession->getQuote()->getAllItems();
$createdAt = $this->_stdTimezone->date()->format('Y-m-d H:i:s');
foreach ($items as $key => $item) {
    if (strtotime($customModel->getExpireTime()) <= strtotime($createdAt)) {
        $this->_cart->removeItem($item->getId());
    }
}
$this->_cart->save();

You need to inject \Magento\Quote\Model\Quote\Item class in your construct as like below way :

/**
 * @var \Magento\Quote\Model\Quote\Item
 */
protected $_itemModel;
/**
 * Add constructor.
 * @param \Magento\Quote\Model\Quote\Item $itemModel
 */
public function __construct(
    .........
    \Magento\Quote\Model\Quote\Item $itemModel
    .........
) {
    .........
    $this->_itemModel = $itemModel;
    .........
}

Add this below code in your function

$items = $this->_checkoutSession->getQuote()->getAllItems();
$createdAt = $this->_stdTimezone->date()->format('Y-m-d H:i:s');
foreach ($items as $key => $item) {
    if (strtotime($customModel->getExpireTime()) <= strtotime($createdAt)) {
        $this->_itemModel->load($item->getItemId())->delete();
    }
}
$this->_cart->save();

Remove generation/generated folder and clean cache.

RamKrishna, is talk about the right point, you have to update the customer Private content after removing an item from the quote.

See the article for how Magento use update private data

As the private content is updated when request type is POST`,So it means using layout_load_before on get Request you could changes Cart details OR user private data.

So, in this case, you have to perform a post request, which will remove the item from cart and have to implement sections.xml for update cart detail.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Customer:etc/sections.xsd">
    <action name="{FrontendName}/{contollerName}/{POSTACtionName}">
        <section name="cart"/>
    </action>
</config>
