Starting with LWC

To know How to Setup VS Code for Salesforce Please visit : VS Code Setup

Lightning Web Component is having three main bundle Elements,

  1. nameSpace.hlml              = to show the UI View
  2. nameSpace.js                  = for logic implementations 
  3. nameSpace.js-meta.xml  = for metadata Access
The power of Lightning Web Components is the templating system, which uses the virtual DOM to render components smartly and efficiently. It’s a best practice to let LWC manipulate the DOM instead of writing JavaScript to do it.

Create a web Component from VS Code:
1. First Create Project 
  • Press ctrl+shift+p
  • Select SFDX: Create Project
  • Select Standard Project Template
  • Give a Name to your project
  • Select Project Location Where you want to save locally
  • Open you new Folder
2. Create First LWC Component:
  • Press ctrl+shift+p
  • Select SFDX: Create Lightning Web Component
  • Give a name to your lwc Component
  • location will be default if you donot want to change the location of newly created lwc component.
  • Once press enter your lwc will be created. you'll be seeing three elements in that bundle
Lightning web Component name = lwcHelloWorld

    <lightning-card title="LWC Hello World" icon-name="custom:custom14">
        <div class="slds-card__body slds-card__body_inner">
            Hello {name},

import { LightningElementapi } from 'lwc';

export default class HelloWorld extends LightningElement {
    @api name = 'testing Name';
    @api message = 'How are you?';

<?xml version="1.0" encoding="UTF-8"?>
<LightningComponentBundle xmlns="">
