Transaction Finalizers in Salesforce Apex are a feature that provides developers with a mechanism to execute logic after a transaction is completed, regardless of whether it's successful or encounters unhandled exceptions. This is particularly useful in the context of Asynchronous Apex, such as future methods, batch jobs, and queueable Apex. You can specify a piece of Apex code to run after the asynchronous operation with transaction finalizers. This flexibility allows you to adapt to various scenarios, benefiting resource cleanup, logging, notifications, or other post-processing operations, giving you a sense of control over your code execution. To use a transaction finalizer, you need to implement the Database. Finalizer interface in your Apex class. The execute method in this interface is invoked after the transaction that the asynchronous code is part of either successfully commits or is rolled back due to an exception Transaction finalizers allow you to attach a post-action s...

Platform Events provide a way to deliver secure, scalable, and customizable event notifications within and outside of the Salesforce platform. Platform Events are based on the publish-subscribe model, allowing publishers to broadcast events and subscribers to receive and process those events in real time. Salesforce Event Bus Example: OrderPlaced Platform Event Let's assume you want to create a Platform Event called OrderPlaced__e to represent the event of a new order being placed in your Salesforce org. This event will contain information about the order, such as the order ID, customer name, and total amount. Define the Platform Event Schema: Go to Setup > Platform Events > New Platform Event. Define fields for the event, such as OrderID__c, CustomerName__c, and TotalAmount__c. Publish the Platform Event: You can publish a Platform Event using Apex, Process Builder, Flow, or other methods. Below is an example of publishing an event using Apex. // Publish OrderPlaced event Or...

What is Apex ?  Apex, a strongly typed, object-oriented programming language, empowers developers to execute flow and transaction control statements on the Salesforce servers in conjunction with calls to the API. It's a proprietary language developed by Salesforce, specifically designed to enable the creation of robust business logic within the Salesforce platform. With its syntactical similarity to Java, Apex serves as the backend code that can manipulate data in Salesforce, execute complex validation rules, and automate intricate business processes. Critical features of Apex include: Integration with Salesforce Data : Apex allows you to write complex queries and transactions against the data stored in Salesforce. Transactional Control: Operations in Apex are transactional, meaning that all DML operations can be rolled back if any error occurs during the transaction process. Governor Limits: Salesforce imposes runtime limits, known as governor limits, to ensure that runaway Apex...

Optimizing the performance of Lightning components is crucial for delivering fast and responsive user experiences in Salesforce applications.  Here are some best practices to improve the performance of Lightning components: Use minified versions of libraries and style sheets Use a content delivery network (CDN) Enable browser caching Use smaller image files CDN and Browser Caching wherever possible is a given.  Cloudflare CDN was used. Akamai is another common option. this is a must-have Custom Fonts (TTF files) were used from Google in the site implementation which was surprisingly taking a long time for browsers to download and use. So we moved to standard fonts which increased the score significantly. If you absolutely need to use Custom Fonts, then there are options in the community to preload this custom font as a static resource which loads faster compared to the Google Reference\ The CSS file was heavily optimized and instead of using images, we used CSS styles for some...

Safe Navigation Operator Instead of using explicit, sequential checks for null references, use the safe navigation operator (?.). This new operator short-circuits expressions that attempt to operate on a null value and returns null instead of throwing a NullPointerException. NOTE: All Apex types are implicitly nullable and can hold a null value returned from the operator. Example - Account acc = [SELECT Name FROM Account WHERE Id = :accId]; if (acc != null) {     return acc.Name; } Using Safe Navigation Operator String accName = acc?.acc.Name; String accName =  [SELECT Name FROM Account WHERE Id = :accId]?.Name; The Safe Navigation Operator (?.) in Apex is a feature that allows developers to safely navigate objects and data structures, avoiding null pointer exceptions. When you use the Safe Navigation Operator to access a chain of references, Apex will evaluate the expression from left to right and return null immediately if it encounters a null reference rather tha...

To determine if a Salesforce organization is a sandbox or a production environment in Apex. Salesforce's sObject Organization has a field called IsSandbox, which is true for sandboxes and false for Production. Boolean isSandbox = UserInfo.getIsSandbox(); Organization org = [Select Id, Name, IsSandbox from Organization]; if (org.isSandbox) {     System.debug('The organization is a sandbox.'); } else {     System.debug('The organization is a production environment.'); } You can use this check to conditionally execute logic based on whether the Apex code is running in a sandbox or production environment. This can be useful for implementing different behaviors or configurations specific to each environment. In Salesforce, the Organization object represents metadata and settings for a Salesforce organization. It provides information about the organization's configuration, such as its name, address, edition, features, limits, and more. The Organization object is rep...

The Messaging.CustomNotification class allows you to create, configure, and send custom notifications using Apex code. Here is a basic outline of how you can create and send a custom notification from an Apex trigger: Create a Custom Notification Type : In the Setup, you should create a Custom Notification Type. This defines the type of notification you will be sending from Apex. Use CustomNotification Class : Once you set up your Custom Notification Type, you can craft your Apex code to create the notification. Here's an example code snippet: // Get the Id for our custom notification type CustomNotificationType notificationType = [SELECT Id, DeveloperName FROM CustomNotificationType WHERE DeveloperName='Lead_Due_Diligence_Completed']; Messaging.CustomNotification notification = new Messaging.CustomNotification();  notification.setTitle('Your Notification Title');  notification.setBody('This is the detail of the notification');  notification.setNotification...
