Get Available Lightning Components In Your Org

  1. To get all available lightning components in your org, My Domain should be enabled in your Org.
  2. Log in to your org.
  3. Add componentReference/suite.app in your org domain URL.
  4. It should look like this :  https://yourorgdomain.lightning.force.com/lightning.force.com/componentReference/suite.app
  5. It will open Salesforce Lightning Component Library.
  6. Here you can see all the available components of your Org along with Salesforce Lightning Component examples.

Lightning Formatted URL

A lightning:formattedUrl component displays a read-only representation of a URL as a hyperlink with an href attribute. The link can be a relative or absolute URL.

Example:

<aura:component>  
    <lightning:formattedUrl value="https://www.google.com" tooltip="Google" label="Click to Open" target="_blank" />
</aura:component>

Output:

Lightning Vertical Navigation

A lightning:verticalNavigation component represents a list of links that’s only one level deep, with support for overflow sections that collapse and expand. Here is an example of Lightning Vertical Navigation.

Apex Class:

public with sharing class AuraSampleController{
    
    @AuraEnabled
    public static List<Account> getAccounts(){
        List<Account> accList = new List<Account>();
        accList = [SELECT Id, Name, AccountNumber, Industry From Account LIMIT 10];
        return accList;
    }
}

Lightning Component:

<aura:component controller="AuraSampleController" Implements="flexipage:availableForRecordHome,force:hasRecordId">
    
    <!--Declare Attributes-->
    <aura:attribute name="selectedaccId" type="Id" />
    <aura:attribute name="accList" type="Account[]" />
    
    <!--Declare Handler-->
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>  
    
    <!--Component Start-->
    <div class="slds-m-around--xx-large">
        <lightning:layout>
            <lightning:layoutItem>
                <lightning:verticalNavigation onbeforeselect="{!c.handleBeforeSelect}"
                                              selectedItem="{!v.selectedaccId}"
                                              onselect="{!c.handleOnSelect}">
                    <lightning:verticalNavigationSection label="Select Account">
                        <aura:iteration items="{!v.accList}" var="acc" indexVar="index">
                            <lightning:verticalNavigationItem label="{!acc.Name}" name="{!acc.Id}" />
                        </aura:iteration>
                    </lightning:verticalNavigationSection>
                </lightning:verticalNavigation>
            </lightning:layoutItem>
            <lightning:layoutItem padding="around-medium">
                <p>You have selected : {!v.selectedaccId}</p>
            </lightning:layoutItem>
        </lightning:layout>
    </div>
    <!--Component End-->
</aura:component>

Lightning JS Controller:

({
    doInit: function(component, event, helper) {
        helper.getAccountList(component, event);
    },
    
    handleBeforeSelect: function(component, event) {
        //Write your logic before select of any item
    },
    
    handleOnSelect: function(component, event) {
        //Write your logic on select of any item
    }
})

Lightning JS Helper:

({
    getAccountList: function(component, event) {
        var action = component.get("c.getAccounts");
        action.setCallback(this, function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                var result = response.getReturnValue();
                component.set("v.accList", result);
            }
        });
        $A.enqueueAction(action);
    },
})

Output:

Invoke Visualforce Page Javascript Method From Lightning Component

Lightning Component:

<!--SampleComponent.cmp--> 
<aura:component implements="flexipage:availableForAllPageTypes,force:appHostable" access="global">
    <!--Declare Attributes-->
    <aura:attribute name="vfMsgMethod" type="object" description="this attribute is for visualforce page javascript method"/>
    
    <!--Component Start--> 
    <div class="slds-m-around_xx-large">
        <lightning:button variant="Brand" class="slds-button" label="Submit" onclick="{!c.doAction}"/>
    </div>
    <!--Component End-->
</aura:component>

Lightning Controller:

({
    doAction : function(component, event, helper) {
        var msg = 'Welcome to Salesforce Ohana';
        var msgMethod = component.get("v.vfMsgMethod");
        msgMethod(msg, function(){
            //handle callback
        });
    }
})

Lightning App:

<!--SampleApp.app--> 
<aura:application extends="ltng:outApp" access="global">
    <!--Lightning component-->
    <aura:dependency resource="c:SampleComponent"/>
</aura:application>

Visualforce Page:

<apex:page sidebar="false" showHeader="false">
    <apex:includeLightning />
    <!--Lightning Container-->
    <div style="width:100%;height:100px;" id="LightningContainer"/>
    
    <script type="text/javascript">
    //Create Lightning Component
    $Lightning.use("c:SampleApp", function() {
        $Lightning.createComponent("c:SampleComponent", { 
            vfMsgMethod : getMessage, //Method to call from lightning component
        },"LightningContainer", function(component) {
            console.log('Component created');
        });
    });
    
    //Function to call from Lightning Component
    function getMessage(welcomeMsg){
        alert(welcomeMsg);
    }
    </script>
</apex:page>

Invoke Lightning Component Methods From Visualforce Page

We can use aura:method to invoke lightning controller methods from visualforce page. The below example is to call Lightning Component methods from visualforce page.

Lightning Component:

<!--SampleComponent.cmp--> 
<aura:component implements="flexipage:availableForAllPageTypes,force:appHostable" access="global">
    <!--Aura Method-->
    <aura:method name="welcomeMsgMethod" action="{!c.doAction}" access="global"> 
        <aura:attribute name="message" type="Object" /> 
        <aura:attribute name="name" type="String"/> 
    </aura:method>
    
    <!--Declare Attributes-->
    <aura:attribute name="msg" type="String"/>
    
    <!--Component Start--> 
    <div class="slds-m-around_xx-large">
        <!--Print Welcome Message--> 
        {!v.msg}
    </div>
    <!--Component End-->
</aura:component>

Lightning Controller:

({
    doAction : function(component, event, helper) {
        //Get Parameters
        var params = event.getParam('arguments');
        if (params) {
            //Get Welcome message parameter
            var msg = params.message.message;
            var developerGroup = params.message.developerGroup;
            //Get name parameter
            var name = params.name;
            //Set welcome message and name
            component.set("v.msg", name + ' ' + msg + ' ' + developerGroup);
        }
    }
})

Lightning App:

<!--SampleApp.app--> 
<aura:application extends="ltng:outApp" access="global">
    <!--Lightning component-->
    <aura:dependency resource="c:SampleComponent"/>
</aura:application>

Visualforce Page:

<apex:page>
    <apex:includeLightning />
    <!--Lightning Container-->
    <div style="width:100%;height:100px;" id="LightningContainer" />
    
    <script type="text/javascript">
    var component; //Variable for Lightning Out Component
    //Create Lightning Component
    $Lightning.use("c:SampleApp", function() {
        $Lightning.createComponent("c:SampleComponent", { },
                                   "LightningContainer",
                                   function(cmp) {
                                       component = cmp;
                                       console.log('Component created');
                                   });
    });
    
    //Method to call Lightning Component Method
    var getWelcomeMessage = function(){
        component.welcomeMsgMethod({message : "Welcome to Salesforce Ohana", developerGroup: "Bengaluru"}, "Biswajeet Samal");
    }
    </script>
    
    <apex:form>
        <!--Button to call Javascript method-->
        <apex:commandButton value="Get Welcome Message" onclick="getWelcomeMessage();return false;"/>
    </apex:form>
</apex:page>
