5. Base Lightning Components

6. How can my app
look like this?

7. Can I use the
CSS in my app?

8. Can you make
it easier?

9. Base Lightning Component Goals
 Easy to adopt
• Patterned after HTML standards making it easy to adopt.
 Componentized
• Components are self contained and can be composed to build experience
components
 Minimal CSS
• Styled using the Salesforce Lightning Design System (SLDS), ensuring that your
components match the Lightning Experience and Salesforce1 Mobile seamlessly
• They evolve with SLDS
 Accessible by design: Supporting WCAG 2.0 and Section 508 standards

10.  Facilitate reusability over all other
principles
 Start with restrictive shape and relax on
request
 Optimize for best practices and make
bad practice harder to implement
 Develop components for the 80%
Base Lightning Component Philosophy
Base
Lightning

and databound
components
Eg: inputField,
outputField, list, lookup

Lightning Data Service

23. Components Drive Modern UI Experiences

24. Before Lightning Data Service
Property
Status
Property
Map
Mortgage
Calculator
Property
Controller
- getProperty
getProperty(abc)
getProperty(abc)
getProperty(abc)
Client Server

25. Challenges
1. Multiple calls to the server for the same record
2. Code-centric
– Javascript at the client-side
– Apex at the server-side (including CRUD and FLS enforcement)
3. UI inconsistencies
– Each component has its own copy of the data
– Changes made in one component are not reflected in other
components

26. Introducing Lightning Data Service
• Declarative CRUD operations
• No Apex
• No SOQL
• Limited Javascript (Edit mode only)
• Handles sharing rules and field level security
• Shared record cache

27. Lightning Data Service
Property
Status
Property
Map
Mortgage
Calculator
Client Server
Shared Record Cache
<force:record recordId="abc"/>
<force:record
recordId="abc"/>
<force:record recordId="abc"/>

28. Example
<aura:component implements="force:hasRecordId,flexipage:availableForAllPageTypes"
access="global">
<aura:attribute name="recordId" type="Id" />
<aura:attribute name="property" type="Property__c" />
<force:recordPreview recordId="{!v.recordId}"
targetRecord="{!v.property}"
fields="['Id', 'Status__c']" />
{!v.property.Status__c}
</aura:component>

29. Example 2: EDIT mode
<aura:component implements="force:hasRecordId,flexipage:availableForAllPageTypes"
access="global">
<aura:attribute name="recordId" type="Id" />
<aura:attribute name="property" type="Property__c" />
<force:recordPreview aura:id="propertyService"
recordId="{!v.recordId}"
targetRecord="{!v.property}"
fields="['Id', 'Status__c']"
mode="EDIT"/>
<ui:inputText label="Status:" value="{! v.property.Status__c}"/>
<lightning:button onclick="{!c.onSaveClicked}">Save</lightning:button>
</aura:component>

30. Saving the Record
onSaveClicked : function(component) {
component.find("propertyService").saveRecord();
}

31. Synching Records in Edit Mode
<aura:component implements="force:hasRecordId,flexipage:availableForAllPageTypes"
access="global">
<aura:attribute name="recordId" type="Id" />
<aura:attribute name="property" type="Property__c" />
<force:recordPreview aura:id="propertyService"
recordId="{!v.recordId}"
targetRecord="{!v.property}"
fields="['Id', 'Status__c']"
mode="EDIT"
recordUpdated="{!c.onRecordUpdated}"/>
<ui:inputText label="Status:" value="{! v.property.Status__c}"/>
<lightning:button onclick="{!c.onSaveClicked}">Save</lightning:button>
</aura:component>

32. Reloading the Record
onRecordUpdated : function(component, event, helper) {
var changeType = event.getParams().changeType;
if (changeType === "CHANGED") {
component.find("propertyService").reloadRecord();
}
}

33. Summary
Without Lightning Data Service With Lightning Data Service
Code-centric (Apex, SOQL, FLS,
Javascript)
Declarative (no code)
Components make multiple calls to
the server for the same record
Components get record from local
record cache which manages server
access transparently and efficiently
Each component has its own copy of
the record
Components share a single copy of
the record
