Salesforce Aura Web Components

In the evolving landscape of Salesforce development, Aura Components emerge as a pivotal technology for creating dynamic, responsive applications. These components serve as the building blocks of the Salesforce Lightning Experience, offering developers a powerful toolkit for crafting custom user interfaces. 

This blog delves into the core aspects of Aura Components, providing a comprehensive overview of their structure, functionality, and the benefits they bring to Salesforce development.

By reading this blog, you will learn:

• Understand what Aura Components are and their role in Salesforce development.
• Discover the essential parts of an Aura Component Bundle and their functions.
• Gain insights into how to develop and implement Aura Components in your Salesforce applications.
• Explore the advantages of Aura Components, including their out-of-the-box component set and event-driven architecture.

Let’s get started!

Aura Components

Also known as base lightning components in Salesforce, Aura components are reusable and the self-contained module of an application. You can configure and assemble the components to form new components in the application.

Aura Component Bundle

Here is the breakdown of the Aura Component Bundle:

• Component or Application: It is used for the markup of the app or the component. Each bundle can only hold one app resource or component at a single time.
• CSS Styles: It is used for the Styles of components.
• Controller: It is a client-side controller which is used to handle the events or the actions in the component.
• Design: It is necessary for those components which are used in lightning pages and lightning app builders.
• Helper: In the component’s bundle, the JavaScript methods are called from any of the JavaScript chunks of code.
• Documentation: A sample piece of code or a description or one or multiple references to the components.
• Renderer: It is a client-side renderer that is used to override the default rendering for the appropriate component.
• SVG: It is used for the custom icon resource in the lightning app builder.

Examples of Aura Component

Scenario: You need to show a list of contacts from your org on a record page. Given below are the files that will form part of the aura component bundle.

Component file 

‹aura:component implements=”force:appHostable,flexipage:availableForA11PageTypes,flexipage:availableForRecordHome,

force:hasRecordId, forceCommunity:availableForA11PageTypes,force:lightningQuickAction*

controller-“contactAura” access=”global* >

‹aura:attribute name=”contactRows* type=*Object 1*/>

‹aura:handler name=”init” value=”(ithis) action=”(Ic.doInit) />

‹div class=”container”>

<p>

<b> List of Contacts </b>

</p>

<table class-“table table-bordered table-hover”>

<thead»|

<tr>

<th> < strong> Name </strong> </th>

</tr>

</thead>

<tbody>

(aura:iteration var=”cell” items=”{Iv.contactRows)”>

<tr>

<td> {Icell.Name) </td>

</tr>

</aura: iteration>

</tbody>

</table>

</ div>

‹/aura:component>

Controller.JS File

({

//Calling a doInit function when the component is loaded

doInit : function (component, event, helper){

helper. getAllContacts (component) ;

}

} )

Helper.js file 

({

//This function is calling from the controller and this method is taking

//the values from the apex class.

getAllContacts: function (component, event, helper) {

var action = component.get (“c.get10COntacts” ) ;

action.setCallback(this, function(a){

component.set(“v.contactRows”, a.getReturnValue()) ;

}) ;

$A.enqueueAction(action) ;

}

} )

Apex Class

public class contactAura {

@AuraEnabled

public static List<Contact> get10COntacts ( )

{

//Fetching the contacts from the org

return [SELECT Id, NAME FROM Contact Limit 10] ;

}

}

Benefits of Aura Components

Out-of-the-Box Component Set

• Accompanies an out-of-the-case set of parts to launch building applications.
• You don’t need to invest your energy enhancing your applications for various gadgets as the parts deal with that for you.

Rich component ecosystem

• Make business-prepared parts and make them accessible in Salesforce 1, Lightning Experience, and Communities.
• Salesforce1 clients access your parts by means of the route menu.

Performance

• Utilizes a stateful customer and stateless server engineering that depends on JavaScript on the customer side to oversee Ul part metadata and application information.
• The customer calls the server only when it’s important; for instance, to get more metadata or information.

Event-driven architecture

Utilizes an occasion driven design for better decoupling between parts. Any part can prefer an application occasion, or to a part occasion they can see.

Faster development

• Engages groups to work quicker with out-of-the-case parts that work flawlessly with work area and cell phones.
• Building an application with parts works with an equal plan, further developing by and large improvement effectiveness.
• Parts are embodied, and their internals stay private, while their public shape is apparent to customers of the part.

Conclusion

Aura Components stand as a cornerstone in Salesforce development, offering a flexible and powerful approach to building sophisticated and interactive applications. By understanding and utilizing these components, developers can significantly enhance the user experience, streamline development processes, and create scalable solutions within the Salesforce ecosystem.
