Hi Roshan,

>> https://www.sfdckid.com/2019/08/salesforce-lightning-component-to-display-contacts.html

The above link has an example of showing related contacts in the lightning component you can simply replace this with contract soql.

Below is the example for quick reference: 
Apex Class-------------------------------------------------
public with sharing class AjinkyaTestLightningAccController 
{
    @AuraEnabled
    public static list<Contact> getRelatedList(Id recordId)
    {
        List<Contact> Conlist = [Select id, name,firstname,lastname from Contact where AccountId=: recordId ];
        return Conlist;
    }
}
Cmp-------------------------------------------------------
<aura:component controller = "AjinkyaTestLightningAccController" implements="flexipage:availableForRecordHome,force:hasRecordId" access="global" >
    <aura:attribute name="recordId" type="Id" />
    <aura:attribute name="ContactList" type="Contact[]" />
    <aura:handler name="init" value="{!this}" action="{!c.myAction}" />
    <lightning:card iconName="standard:work_capacity_usage" title="Related Contacts">
        <aura:if isTrue="{!not(empty(v.ContactList))}">
            <table class="slds-table slds-table_cell-buffer slds-table_bordered">
                <thead>
                    <tr class="slds-line-height_reset">
                        <th class="slds-text-title_caps" scope="col">
                            <div class="slds-truncate" title="First Name">FirstName</div>
                        </th>
                        <th class="slds-text-title_caps" scope="col">
                            <div class="slds-truncate" title="last Name">LastName</div>
                        </th>
                    </tr>
                </thead>
                <tbody>
                    <aura:iteration  items="{!v.ContactList}" var="con">
                        <tr class="slds-hint-parent">
                            <td data-label="File Name">
                                <div class="slds-truncate" title="File Name">{!con.FirstName}</div>  
                            </td>
                            <td data-label="File Name">
                                <div class="slds-truncate" title="File Name">{!con.LastName}</div>  
                            </td>
                        </tr>
                    </aura:iteration>
                </tbody>
            </table>
            <aura:set attribute="else">
                <div Style="text-align : center"> " There are no related contacts "</div>
            </aura:set>
        </aura:if>
    </lightning:card>
</aura:component>
JS------------------------------------------------------
({
myAction : function(component, event, helper) 
    {
        var ConList = component.get("c.getRelatedList");
        ConList.setParams
        ({
            recordId: component.get("v.recordId")
        });
        
        ConList.setCallback(this, function(data) 
                           {
                               component.set("v.ContactList", data.getReturnValue());
                           });
        $A.enqueueAction(ConList);
}
})

Let me know if it helps you and close your query by marking it as solved so that it can help others in the future.  

Thanks.
