@track vs @api vs @wire

@Api : @Api properties are considered Public and we use them in 2 scenarios: 1. If we want to exchange data between 2 components. 2. If we want to pass values from App builder (in the aura, this is achieved using the ".design" file and the attributes declared in "design file" are called "design attributes"). childCmp.html < template > Value received From Parent are : Name = {childvar.name} Age = {childvar.age} </ template > childCmp.js import { api, LightningElement,track } from 'lwc'; export default class ChildCmp extends LightningElement { @api childvar; } parentCmp.html < template > <c-child-cmp childvar={passval}></c-child-cmp> </ template > parentCmp.js import { LightningElement } from 'lwc'; export default class ParentCmp extends LightningElement { passval= { name: 'Manju', age: 29

Display Loggedin User details without Apex in Aura

Component: < aura:component implements = "force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,force:lightningQuickAction" access = "global" > < aura:attribute name = "currentUser" type = "User" /> < force:recordData fields = "Username,Name, Email" recordId = "{!$SObjectType.CurrentUser.Id}" targetFields = "{!v.currentUser}" mode = "VIEW" /> < lightning:button variant = "brand" label = "Load Report" onclick = "{! c.handleClick }" /> </ aura:component > Controller: ({ handleClick : function(component, event, helper) { var UserName = $ A . get( "$SObjectType.CurrentUser" ); alert( ' User Name--- ' + component .

Order of Execution in Salesforce

When it comes to the order of execution, many seasoned Salesforce Developers will also get confused. After completing the plural sight video created by Daniel Stange and Don Robins( PluralsightCourseLink ), I thought worth sharing the below 2 diagrams which explain the order of execution. Apex Transaction + DataBase Transaction [ If there is any apex logic, example: triggers/batch apex then only it is treated as apex transaction. ] Max no.of times execution happens if DML occurs through apex + Workflow+ Process builder: tHiNk gooD and dO thE bEsT.........MANJU NATH 🌝
