  A headless quick action executes custom code in a Lightning web component. Unlike a screen action, a headless action doesn’t open a modal window. Expose invoke() as a public method for headless quick actions; the invoke() method executes every time the quick action is triggered. Return type of invoke() is void . Using async will make invoke()  execute asynchronously.  // js file import { LightningElement, api } from 'lwc'; import { ShowToastEvent } from 'lightning/platformShowToastEvent'; export default class DispatchEventHeadlessAction extends LightningElement {     @api recordId;      isExecuting = false;     @api async invoke() {           if (this.isExecuting) {           // This code uses a boolean flag to block a double execution            return;          }           this.isExecuting ...

Communication between unrelated components in salesforce using  Lightning Message Service (LMS) LMS is a publish and subscribe service that facilitates communication between Lightning web components, Aura components, and Visualforce pages.
 Step1: Create a Lightning Message Channel Create a folder named “messageChannels” under force-app/main/default Create a file under the "messageChannels" folder with the name <channel>.messageChannel-meta.xml Example: <?xml version="1.0" encoding="UTF-8" ?> <LightningMessageChannel xmlns="http://soap.sforce.com/2006/04/metadata">     <masterLabel>CountUpdated</masterLabel>     <isExposed>true</isExposed>     <description>Message Channel to pass Count updates</description>      <lightningMessageFields>         <fieldName>operator</fieldName>         <description>This is the operator type...

What is GraphQL?   GraphQL is a standard query language for APIs and a runtime for fulfilling those queries with your data. It provides users with a single endpoint to request all necessary data from in a single request. Applications that utilise GraphQL APIs are frequently far more efficient than those that stick with REST APIs. This is due to their capacity to retrieve all required data in a single invocation, which reduces the number of round trips to the server, allowing you to customise it to meet your needs. Why GraphQL is better than REST API? REST API is the gold standard for APIs, yet traditional REST APIs present significant issues when developing modern, highly performant, and scalable online and mobile applications. REST endpoints do not allow client changes to the API endpoint's response.   For example, when fetching a user's phone number from a REST API, receiving extraneous data beyond the number adds unnecessary costs for both the server and the requester. ...
