In this blog we will learn the implementation of pagination in lightning component, with the use of lightning bundle.
Pagination in Lightning Component
Goto Setup > Develop > Apex Classes > New
Write the following code in Apex Class:
Apex Controller-
public with sharing class pagination {

@AuraEnabled
public list<account> acc;
@AuraEnabled
public integer offst;
@AuraEnabled
public integer total;
@AuraEnabled
public boolean hasprev;
@AuraEnabled
public boolean hasnext;
private static integer pagesize=8;
private static integer offset;
@AuraEnabled
public static pagination getacc(boolean next,boolean prev,decimal off){
offset = (integer)off;
list<account> li = new list<account>();
integer listlength = [Select count() from account where name!=null];
if(!schema.sobjecttype.Account.isaccessible()){
li = new list<account>();
}else{
if(next==false && prev==false){
li = [Select id,name,accountSource,AccountNumber,Active__c from account LIMIT :pagesize OFFSET :offset];
}else if(next==true && (offset+pagesize)<=listlength){
offset=offset+pagesize;
li = [Select id,name,accountSource,AccountNumber,Active__c from account LIMIT :pagesize OFFSET :offset];
}else if(prev==true && offset>0){
offset=offset-pagesize;
li = [Select id,name,accountSource,AccountNumber,Active__c from account LIMIT :pagesize OFFSET :offset];
}
}
pagination pg = new pagination();
pg.acc = li;
pg.offst = offset;
pg.hasprev = hasprev(offset);
pg.hasnext = hasnxt(offset,listlength,pagesize);
return pg;
}
private static boolean hasprev(integer off){
if(off>0)
return false;
return true;
}
private static boolean hasnxt(integer off,integer li,integer ps){
if(off+ps<li)
return false;
return true;
}
}
Open Devloper Console.
Create New Lightning Component for SVG. Go to File > New > Lightning Component. Name it SVG and write the following code:
<aura:component implements="force:appHostable"><!--implements="force:appHostable" allows to create lightning tabs-->
<!--
/**
* Webkul Software.
*
* @category Webkul
* @author Webkul
* @copyright Copyright (c) 2010-2016 Webkul Software Private Limited (https://webkul.com)
* @license https://store.webkul.com/license.html
*/
-->
<aura:attribute name="class" type="String" description="CSS classname for the SVG element" />
<aura:attribute name="xlinkHref" type="String" description="SLDS icon path. Ex: /assets/icons/utility-sprite/svg/symbols.svg#download" />
<aura:attribute name="ariaHidden" type="String" default="true" description="aria-hidden true or false. defaults to true" />
</aura:component>
Now refer to right side of the column click Renderer. 
Write the following code:
({
/**
* Webkul Software.
*
* @category Webkul
* @author Webkul
* @copyright Copyright (c) 2010-2016 Webkul Software Private Limited (https://webkul.com)
* @license https://store.webkul.com/license.html
*/
render: function(component, helper) {
//grab attributes from the component markup
var classname = component.get("v.class");
var xlinkhref = component.get("v.xlinkHref");
var ariaHidden = component.get("v.ariaHidden");
//return an svg element w/ the attributes
var svg = document.createElementNS("http://www.w3.org/2000/svg", "svg");
svg.setAttribute('class', classname);
svg.setAttribute('aria-hidden', ariaHidden);
svg.innerHTML = '<use xlink:href="'+xlinkhref+'"></use>';
return svg;
}
})
You can now use the SVG component wherever you need.
Create a new lightning Component. File > New > Lightning Component
Write the following Code in the Component:
Component-
<aura:component controller="pagination">

Anyways, after staring at it for 10 hours I figured out what you were trying to do. So I guess thanks.
But please write more readable Clean Code!
Thank you for your precious feedback. I understand that you have exhausted your precious time on such coding which might be achieved within no time as per your point of view. However, I would love to get in touch with you in order to figure out what are the points that might be implemented in more effective way as you said in your response.
