LWC Passparameters


Hi,
I've created class and method which retrieves List<Account> then it call Visualforce page contains Lightning Web Component.

Is there any way to pass List<Account> from this method to my LWC

Class

public override SearchResult SearchRecords()
    List<Account> accountsCust = SearchClients.searchClientFromCustomerByPhoneMock2(callFolderId);
    if(accountsCust != null && accountsCust.size()>0){  
        result.objectType = 'Url'; 
         Set<String> setIds = new Set<String>();
         setIds.add('https://test.lightning.force.com/apex/SearchClientCustomerByPhoneResultsPage');
        .
        .            
    }
}

Page
<apex:page extensions="SearchClients">
<apex:includeLightning />
<script>
    //Tell your Visualforce page to use your Lightning app
    $Lightning.use("c:SearchClientCustomerByPhoneResultsApp", function() {

        // Write a function that creates the component on the page
        $Lightning.createComponent("c:searchClientCustomerByPhoneResults",
                                   {},
                                   "divid",
                                   function(cmp) {      
                                   })
    });
    </script>
    <body>
        <div id="divid" />
    </body>
</apex:page>

 connectedCallback() {
    this.accounts;
 }

If you want to pass anything back to Lightning Components, then you need to the annotation @AuraEnabled in your apex controller.

In Class A:
I call webservice to retrieve List of account from externe system 
if list<Account> returned size >0 then I open visualforce page which containes my lightning web component
my LWC execute a method connectedCallback which call an other method in class B this method contains annotation @AuraEnabled
My question is how to pass List<Account> retreived in class A to LWC to display it?
is there any way to pass this list<Account> from class A to page VF then to LWC?
OR pass this List<Account> from class A to class B then it will be called from connectedCallback()?
OR I'am forced to redo the same call webservice from connectedCallback()?

thx for help

You need to define an attribute of type = List in the component and then assign the value to this attribute in your controller.js with values from your Apex Controller. This should fix the issue you are facing.
