  17. 17. Developer Productivity
  18. 18. Salesforce Development Workflows Org Development Package Development Use the workflows you know to deploy to sandboxes and production orgs Use packages and scratch orgs for flexible and modular release managememnt
  19. 19. What’s new with Org Development Modern tools are now integrated with traditional methods Use Salesforce CLI for sandbox operations (beta) force:org commands to create, clone, delete, list, and display information Use CLI source Commands for Full Application Lifecycle source:deploy and source:retrieve are consistent with mdapi
  20. 20. What’s new with Package Development Create environment with more scratch org features Configure scratch org with Einstein Bots Turn on Einstein feature in Dev Hub and add the chatbot feature in scratch org definition file Scratch org version selection is available Select previous, current or preview version with release property in scratch org definition file
  21. 21. More CLI and VS Code updates Run Salesforce CLI commands faster with oclif Salesforce CLI is migrated to Heroku's Open CLI Framework (oclif) for v7 of Salesforce CLI Create DX project with expanded scaffolding use force:project:create --template empty for minimal amount of scaffolding Lightning Explorer for VS Code Salesforce Aura Extension for VS Code now supports code completion for Aura component tags, attributes, and JavaScript (Beta) Faster list of authorized orgs with force:auth:list

  28. 28. Platform Events and Change Data Capture
  29. 29. Capture changes without custom code Easily select objects to capture data changes on with clicks Keep your key systems up to date Ensure downstream systems always have the right data Scale with ease to millions of events daily Events are held for 72-hours to prevent data loss Change Data Capture Generally Available 12/18 Detect changes on Salesforce records in real-time No polling No batch ETL processes No point-to-point integrations “/data/ChangeEvents” Channel Account { Name : } Account { Name : } Account { Name : “Acme” } “Acme” “Acme” “Acme”
  30. 30. Async Apex Triggers GA Complex computations and logic executed outside of the transaction True Post-Commit Execution Triggers execute asynchronously after a transaction Faster End-user Experience Less logic and computation inside the transaction leads to quicker end-user experiences and fewer limit concerns Event-driven and Decoupled Errors in processing won’t rollback or impact the transaction trigger CaseChangeEventTrigger on CaseChangeEvent (after insert) { // Setup .... // Perform heavy (slow) computation .... // Cleanup / Finish .... }
  31. 31. trigger CaseChangeEventTrigger on CaseChangeEvent (after insert) { List<CaseChangeEvent> changes =; Set<String> caseIds = new Set<String>(); // Get all Record Ids for this change for (CaseChangeEvent change : changes) { List<String> recordIds = change.ChangeEventHeader.getRecordIds(); caseIds.addAll(recordIds); } // Perform heavy (slow) computation determining Red Account RedAccountPredictor predictor = new RedAccountPredictor(); Map<String, boolean> accountsToRedAccountStatus = predictor.predictForCases(new List<String>(caseIds)); // Publish platform events for predicted red accounts List<Red_Account__e> redAccountEvents = new List<Red_Account__e>(); for (String acctId : accountsToRedAccountStatus.keySet()) { if (rating=='Red') { redAccountEvents.add(new Red_Account__e(Account_Id__c=acctId, Rating__c=rating)); } } if (redAccountEvents.size() > 0) { EventBus.publish(redAccountEvents); } } When should I use Async Triggers? Any calculation or piece of logic that can happen after the data is changed Keep critical logic in the transaction Data validation, data consistency, and required prerequisite operations before data is changed Processing that can happen “later” -- Heavyweight computations -- Einstein (or other ML/AI) operations -- Notifications to other systems -- Joining of data from different sources -- Summary calculations
  32. 32. External Change Data Capture GA Detect changes on external objects and execute business logic Declarative Setup and Enablement Use clicks to enable -- no code required Deep Platform Integration Change events are delivered to Apex Triggers and external subscribers OData 4 Compatible Leverage your existing connectors and start receiving change notifications today trigger LowOnStock on Product__ChangeEvent (after insert) { // Filter out deleted product events. Get product ids Set<Id> ids = new Set<Id>(); for (Product__ChangeEvent event: { if (event.ChangeEventHeader.getChangeType() != ‘DELETE’) { ids.add(event.ChangeEventHeader.getRecordIds()[0]); } } // Get Products for associate change events low in stock List<Product__x> products = [SELECT Id, Stock__c FROM Product__x WHERE Id in :ids AND Stock__c < 5]; // Get potential buyers interested in product List<Buyer__c> buyers = ProductBuyers.getPotentialBuyers(products); // Send SMS to potential buyers. Notifier.sendSms(buyers, ‘We have ‘ + products.size() + ‘ products low on stock that might interest you.’) }
