Easily update and query data on Salesforce with refreshApex method!

To start, import the refreshApex function from @salesforce/apex. 

This method is called to retrieve updated data from Apex and refresh the cache of a wired property.

Here's an example:

import { refreshApex } from "@salesforce/apex";

refreshApex(valueProvisionedByApexWireService);

Remember to use {valueProvisionedByApexWireService} as either an annotated property or an argument received by the wired function.

Please note that using refreshApex for non-Apex wire adapters is no longer recommended. 

Instead, utilize notifyRecordUpdateAvailable(recordIds) to refresh data returned by non-Apex wire adapters.

// Example of refreshing data for a wired property

// after you update data via imperative Apex.

import { refreshApex } from '@salesforce/apex';

import { notifyRecordUpdateAvailable } from 'lightning/uiRecordApi';

import getOpptyOverAmount from '@salesforce/apex/OpptyController.getOpptyOverAmount;

@wire(getOpptyOverAmount, { amount: '$amount' })

opptiesOverAmount;

// Update the record in Apex, such as via a button click

// Refresh Apex data that the wire service provisioned

handler() {

  updateRecordApexMethod()

  .then(() => {

      refreshApex(this.opptiesOverAmount);

      notifyRecordUpdateAvailable(recordIds); 

      // Refresh the Lightning Data Service cache

  });

}
