[SalesForce] Listen LWC Event From Aura Component

In the new salesforce release Spring'20, we have this privilege to set the predefined values. We can now make the field API names and their values as a string and pass it to pageReference.state.defaultFieldValues attribute on standard__objectPage page reference types.

You can have the look here - https://releasenotes.docs.salesforce.com/en-us/spring20/release-notes/rn_lc_navigate_to_record_dfv.htm

For instance -

import { LightningElement } from 'lwc';
import { NavigationMixin } from 'lightning/navigation';

export default class Demo extends NavigationMixin(LightningElement) {

    handleClick(){
        let temp = {
            type: 'standard__objectPage',
            attributes: {
                objectApiName: 'Account',
                actionName: 'new'                
            },
            state : {
                nooverride: '1',
                defaultFieldValues:"Name=Salesforce,AccountNumber=A1,AnnualRevenue=37000,Phone=7055617159"
            }
        };
        this[NavigationMixin.Navigate](temp);
    }

}

Note - Spring'20 is only available for sandboxes for now.

e.force:navigateToComponent is deprecated. I wont recommend using it.

Instead use lightning:navigation , you generate state(aka URL params) by setting page references.

<lightning:navigation aura:id="navService"/>

JS:

 var navService = cmp.find("navService");
    // Sets the route to /lightning/o/Account/home
    var pageReference = {
        type: 'standard__component',
        attributes: {
            componentName: 'c:testContainer'
        },
        state : {
            c__recordId : cmp.get('v.recordId');
        }
    };

    // Set the URL on the link or use the default if there's an error
    var defaultUrl = "#";
    navService.generateUrl(pageReference).then($A.getCallback(function(url) {
        window.open(url,'_blank'); // This will open in new tab with pageReference with state/URL params you sent while creating instance of pageReference
    }

In your client-side aura controller, set the pageReference attribute for the Component . Set the URL on your link using the generateUrl() method, which is useful for opening links in a new tab

Now you have to make your LWC component listen to pageReference and get state(the recordId that we sent)

you can do that in your lwc by declaing @wire(CurrentPageReference)

import { CurrentPageReference } from 'lightning/navigation';

export default class TestLWC {


     // Injects the page reference that describes the current page
    @wire(CurrentPageReference)
    currentPageReference; 

    get recordIdFromState(){
        return this.currentPageReference &&
            this.currentPageReference.state.c__recordId; // Once you have recordId you can call apex
    }
}
