3. Lightning Components
Ø Aura design tokens now supported in Lightning Web Components
Ø Instead of copying and pasting you can now define CSS values in one place and refer to
them from LWCs.
Ø Lightning (aura) tokens file:
Ø Can reference Salesforce community styles, so that theme changes done declaratively
automatically update your component
Ø The LWC’s CSS file:
Ø You may prefer to use SAAS or LESS or something like that instead

4. Lightning Components
Ø @track is no longer needed – Happens automatically
Ø @track was used to track private property’s value and rerender a component when it
changes (a.k.a. private reactive properties) as opposed to @api (public)
Ø Before: @track amount;
Ø After: amount;
Ø Not so fast, folks! Objects and Array Elements still need @track

5. Lightning Components
Ø Base Components have been open sourced
Ø Use the source as a start for your own
Ø Use the source as a reference for best practices
Ø When in doubt, consult them
Ø However, not all have been open sourced
Ø Some of the older ones have not-so-great code and need to be cleaned up, but they will be
open sourced at some point
Ø No lightning-datatable!
Ø https://github.com/salesforce/base-components-recipes/tree/master/force-
app/main/default/lwc

6. Record Create Page Defaults
Ø In classic we had URL hacks to prepopulate standard pages.
Ø Used in custom buttons or links, many times
Ø /a0U/e?CF00Ni000000EpsgO={!Opportunity.Name}&CF00Ni000000EpsgO_lkid={!Opp
ortunity.Id}&00Ni000000EpsgY={!Opportunity.Description}
Ø It was not supported, but so widely used by Salesforce’s customers that there was no way
that Salesforce would have broken it.
Ø There has been on equivalent in Lightning, until now. And, it is officially supported!
Ø /lightning/o/Account/new?defaultFieldValues=
Name={!URLENCODE(Account.Name)}, OwnerId={!Account.OwnerId},
AccountNumber={!Account.AccountNumber}, NumberOfEmployees=35000,
CustomCheckbox__c={!IF(Account.SomeCheckbox__c, true, false)}

7. Local Development in Beta
Ø We have been doing this for a while with angular in VF and a local node server with the
localhost conditional components. But no way to do with LCs existed!!!
Ø Install the plugin:
Ø …yada, yada, yada…
Ø Start the server:
Ø Go to http://localhost:3333 (give –port <port-num> for different port)
Ø Alternatively, just use VS Code’s command palette
Ø What’s supported/not:
Ø https://developer.salesforce.com/docs/component-
library/documentation/lwc/lwc.get_started_local_dev_modules
Ø Can use most @salesforce, including @salesforce/apex

8. Security Enhancements are GA – Use ‘em!
Ø WITH SECURITY_ENFORCED
Ø If the running user does not have permissions on the object or field an exception is
generated
Ø For AppExchange Security Review, you must use API version 48.0 or later when
using WITH SECURITY_ENFORCED. You cannot use API versions where the feature was
in beta or pilot.
Ø Security.stripInaccessible
Ø These can be used to pass security review…
Ø …BUT, it is not clear if sec review automations
Ø will recognize them yet.

9. Lightning Message Service (Beta)
Ø LWCs have no built-in application event handling – had to use pubsub.js from SF github
Ø Communicate among Aura, VF pages, and LWCs.
Ø Use a Lightning Message Channel
Ø LWC: @salesforce/messageChannel
Ø VF: $MessageChannel
Ø Aura: lightning:message
Ø WARNING: Beta AND not available in communities, yet.

10. Asynchronous Job Transaction Finalizers (Pilot)
Ø System.Finalizer interface
Ø A way to run code after the job finishes, regardless of success or failure, without polling.

11. Flow Before-Save Update
Ø Analogous to before insert/update trigger
Ø Let’s see a demo!
Ø Remember the best practice for automations, though…
Ø Try to use one automation type per object.
Ø E.g., Avoid mixing before update flows with triggers with process builders, etc.
Ø It quickly gets out of hand.
Ø Debugging is difficult impossible
Ø Easier said than done.

12. Run Flows in System Context (with sharing)
Ø When a user runs a flow that is in system context (with sharing), object- and field-level
security checks are automatically passed when the Flow executes a CRUD element.
Ø Flows & Context
Ø Process Builder processes run in system context, without sharing
Ø Scheduled Flows run in system context, without sharing, as Automated Process user
Ø Top-level, auto-launched Flows and screen Flows run in user context
Ø Flows that are invoked by other processes such as Apex triggers, process builder
processes, or even other Flows — run in the execution context of their caller
Ø Declaratively, you can explicitly declare an auto-launched or screen Flow to always run in
system context, with sharing.

13. Limit Changes of Note
Ø Default daily API allocation increased from 15K to 100K
Ø SOQL Statement length increase from 20K to 100K
Ø SOSL statement length increase from 20K to 100K

14. Aura Components in the ui Namespace Are Deprecated
Ø Salesforce plans to end support for the deprecated components on May 1, 2021
Ø Replace the deprecated components with their counterparts in the lightning namespace
Ø These components are faster, more efficient, and they implement Lightning Design System
styling out-of-the-box.

15. Assign Tasks to a Queue
Ø When reps assign tasks to a queue, those tasks are available to members of the queue

16. Clone Objects Along with Their Related Records
Ø When you click Clone with Related, all of the original object’s related records are also
added to the cloned object

17. Combine Duplicate Cases with Case Merge
Ø Now, support agents can consolidate up to three duplicate cases
Ø Agents can see duplicate cases from the Case record page in the Merged Cases Related
List, which shows a list of all the cases that were merged to form the master case.
Ø If you decide to keep merged cases, they appear in the Merged Cases related list.
Ø If you decide to delete merged cases, only the master case is saved. You can find the other
merged cases in the Recycle Bin for the next 15 days.

18. In-App Guidance Improvements
Ø Customize When Prompts Appear to Users
Ø Specify Profiles When Creating Prompts
Ø Add Videos to Docked Prompts

19. Security Enhancements
Ø Heroku Shield: Support for Apache Kafka on Heroku
Ø Build real-time apps more easily than ever using PHI, PII, and HIPAA-compliant data in a
secure, trusted, and fully managed environment

21. Filter Reports - Field Comparisons with Field-To-Field Filter

Ø See cases modified after the closing date by filtering on cases with a last modified date
after the closed date
