loadContact : function(component) {
var action = component.get("c.getContact");
action.setParams({
contactId : component.get("v.contactId")
});
action.setCallback(this, function(a) {
});
$A.enqueueAction(action);
}
Instead of enqueueAction is there an alternative where I can immediately call the function?
$A.enqueueAction(action) leads to a delay and few items are displayed after some time. Any inputs?
Since Summer '17 Lightning Data Service allows to load record by means of only markup of component
In a nutshell, Lightning Data Service provides reusable Aura components that:
- Minimize XMLHttpRequests (XHRs)
- Fetch records once, reducing network transfers, app server load, and database server load
- Cache record data on the client, separate from component metadata
- Share record data across components
- Enable progressive record loading, caching, and merging more fields and layouts into the cache
- Enable proactive cache population
- Promote consistency by using only one instance of the record data across multiple components
- Create notifications when record data changes
If you have a Lightning application that creates, reads, updates, or deletes records, LDS is the best, most efficient way to do CRUD operations.
Example of usage:
<force:recordData aura:id="forceRecordCmp"
<!-- aura:id is required to reference the component in your Javascript controller -->
recordId="{!v.recordId}"
layoutType="{!v.layout}"
fields="{!v.fieldsToQuery}"
mode="VIEW"
targetRecord="{!v.record}"
targetFields="{!v.simpleRecord}"
targetError="{!v.error}"
/>
The action needs to hit the server. Making the call synchronous would hurt the performance of the application and thus is not allowed.
