How to Update Mini Cart in Magento2 ?

Update mini cart when you are submitting a form

Magento provides a way to update minicart if you are submitting a form. First of all create sections.xml file in ‘etc/frontend’ folder in your module.

Now write following code snippet in sections.xml file

<?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="modulename/controller/addProduct">
<section name="cart"/>
</action>
</config>

Action name: action name is controller where you are submitting form.

Example of this situation may be when you want to set custom price of product in your own controller. This approach will work when you are using POST or PUT form submitting. It will also work for AJAX request.
