Salesforce DX: Test Data migration using Salesforce DX

Here I am going to show case a small POC of Data migration using Salesforce DX, its really easy to use, and the process where you want to maintain the test data in different-different Sandbox, then Salesforce DX is for you.

So lets get started,
Before going further, if you have not installed Salesforce DX in your system and please go ahead and install it you system.

Here is the Trailhead link where you can find link to install and get to know more about SalesforcDX.

After installing open the git bash and check whether SalesforceDX got successfully installed or not.

So let me explain you a bit about this process using dx, here we will use two sandbox, one from where we will export the data and the other is the destination sandbox where we will import the data, now this is the first time process, where we are exporting the data from one sandbox, but if its recurring process then we will have the data in JSON format in our local machine, so we just need to export it to other sandboxes.

Please enter

$ sfdx force

If it show the cloud image made up of DX then its installed, now we will create a project first.

$ sfdx force:project:create -n web //create project, its not necessary you can skip this one also

//Add a new sandbox , on hitting this command it will ask you to login to you sandbox and authorize
$ sfdx force:auth:web:login --setalias my-sandbox --instanceurl

//after this do the same thing again and add another sandbox.
//Now if you want to check how many orgs you have added you can by below command
$ sfdx force:org:list

//you have to define an org as default to so that dx will fetch the data from that org. use below for the same
$ sfdx force:config:set --global

//now export the data, here we are exporting only account data, but you can do allot more then this
$ sfdx force:data:soql:query --query "Select Id, Name From Account"

If you'll check that file that DX has created will have the content something like below

    "records": [
            "attributes": {
                "type": "Account",
                "referenceId": "AccountRef1"
            "Name": "Sinclair Community College"
            "attributes": {
                "type": "Account",
                "referenceId": "AccountRef2"
            "Name": "The Institute of Electrical and Electronics Engineers, Inc."
            "attributes": {
                "type": "Account",
                "referenceId": "AccountRef61"
            "Name": "TestLastName"

In the command prompt you'll be able to see the data count as well.

Now to import the data to another sandbox, you just have to hit another command, as its so easy so here are the things need to consider before hitting the command

1. Define the correct source path of the JSON file.
2. Provide the correct sanbox username.
3. Sandbox should be from the list of the sandbox added in the DX.

//to import data to sandbox
$ sfdx force:data:tree:import --targetusername sfdx-out/export-demo-Account-plan.json

Your command prompt

Woohoo!! you have just performed the data migration using SalesforceDX

Here are some links that will be helpfull

Thanks you!!

Winter'18 - Basic Visualforce is now Ready for Lightning View #Salesforce

In this winter 18 release, Salesforce has upgraded what was required, now even if you are new to SLDS, no need to worry about as Salesforce have introduced "lightningStylesheets" tag just to make your life easy.
Designing in lightning sometime you need to search the class name and then add it your page to check whether its the same that you want.

So here is a simple demo of the old style visualforce page having all the things that we might use, and using the same visuaforce page in Lightning by changing nothing. Everything will taken care by salesforce just by using lightningStylesheets.
I have added almost all type of fields as well just to show how it looks without adding any further styling.

Take a look how it works

Here is the Visualforce page

Some good guy said

Thank you!

Using lightning:tree to display Account Hierarchy #Salesforce Lightning Component #Winter'18

 Winter'18 Salesforce have added a new lightning component called lightning:tree, using this we can display the hierarchy of Salesforce.

In this component is going to be great help to all the devs, when they want achieve the accordion looking hierarchy displaying component. This component support only version 41.0 and above

Here is the working demo

So in this post we have a small component which displays the account hierarchy upto 3 levels, I am not further on achieving the hierarchy of Account using Apex, so I did what I can using just a single SOQL.

Here is the component code

 <aura:component controller="LightningTreeApexController" implements="flexipage:availableForRecordHome,force:lightningQuickActionWithoutHeader,force:hasRecordId"> >  
   <aura:handler name="init" value="{!this}" action="{!c.doInit}" />  
   <aura:attribute name="items" type="Object"/>  
   <aura:attribute name="recordId" type="String"/>  
   <lightning:tree items="{! v.items }" header="Account Hierarchy" onselect="{!c.handleSelect}"/>  

Here Lightning component Controller code

   doInit: function (cmp, event, helper) {  
   handleSelect: function (cmp, event, helper) {  
     //return name of selected tree item  
     var myName = event.getParam('name');  
     alert("You selected: " + myName);  

Here is the helper code

   apexMethod : function(cmp) {  
     var action = cmp.get("c.getAccountHierarchy");  
     action.setParams({ accountId : cmp.get("v.recordId") });  
     action.setCallback(this, function(response) {  
       var state = response.getState();  
       if (state === "SUCCESS") {  
         cmp.set( "v.items", response.getReturnValue());  

Here is Apex Controller

 public class LightningTreeApexController {  
   public static List<items> getAccountHierarchy(Id accountId) {  
     //Wrapper instance  
     List<items> finalWrp = new List<items>();  
     //Going upto 2 level only as per SOQL limit  
     for(Account acc : [ Select Id, Name, Type, ParentId, Parent.Name, Parent.Type, Parent.ParentId, Parent.Parent.Name, Parent.Parent.Type From Account Where Id =: accountId]) {  
       //populating wrapper  
       List<items> trP1 = new List<items>{new items(acc.Type, acc.Name, false, null)};  
       List<items> trP2 = new List<items>{new items(acc.Parent.Type, acc.Parent.Name, false, trP1)};  
       finalWrp.add(new items(acc.Parent.Parent.Type, acc.Parent.Parent.Name, false, trP2));  
     System.debug('finalWrp:::' + finalWrp);  
     // return wrapper  
     return finalWrp;    

Here is wrapper class used in Apex controller

 public class items {  
   public string label { get; set; }  
   public string name { get; set; }  
   public Boolean expanded { get; set; }  
   public List<items> items { get; set; }  
   public items( String name, String label, Boolean expanded, List<items> items) {  
     this.label = label; = name;  
     this.expanded = expanded;  
     this.items = items;

Lightning Data Service - Salesforce Lightning Remote Objects

Lightning Data Service is in Beta, we can use lightning data service to create, upload, delete and edit salesforce object, without using apex controller, that is it is kind of Remote object that we have for salesforce visualforce page.

As it is beta, so many upgrades will be coming in future, Data access with Lightning Data Service is simpler than the equivalent using a server-side Apex controller. Read-only access can be entirely declarative in your component’s markup. It’s built on highly efficient local storage that’s shared across all components that use it. Records loaded in Lightning Data Service are cached and shared across components. Components accessing the same record see significant performance improvements, because a record is loaded only once, no matter how many components are using it.

here is a small and simple exam of lighting data component for creation of Contact record.

Here is the component code
 <aura:component implements="flexipage:availableForRecordHome,force:lightningQuickActionWithoutHeader,force:hasRecordId">  
   <aura:attribute name="account" type="Object"/>  
   <aura:attribute name="simpleAccount" type="Object"/>  
   <aura:attribute name="accountError" type="String"/>  
   <force:recordData aura:id="accountRecordLoader"  
     recordId="{!v.recordId}" fields="Name,BillingCity,BillingState" targetRecord="{!v.account}"  
     targetFields="{!v.simpleAccount}" targetError="{!v.accountError}"/>  
   <aura:attribute name="newContact" type="Object" access="private"/>  
   <aura:attribute name="simpleNewContact" type="Object" access="private"/>  
   <aura:attribute name="newContactError" type="String" access="private"/>  
   <force:recordData aura:id="contactRecordCreator"  
     layoutType="FULL" targetRecord="{!v.newContact}"  
     targetFields="{!v.simpleNewContact}" targetError="{!v.newContactError}" />  
   <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>  
   <!-- Display a header with details about the account -->  
   <div class="slds-page-header" role="banner">  
     <p class="slds-text-heading--label">{!v.simpleAccount.Name}</p>  
     <h1 class="slds-page-header__title slds-m-right--small slds-truncate slds-align-left">Create New Contact</h1>  
   <!-- Display Lightning Data Service errors, if any -->  
   <aura:if isTrue="{!not(empty(v.accountError))}">  
     <div class="recordError">  
       <ui:message title="Error" severity="error" closable="true">  
   <aura:if isTrue="{!not(empty(v.newContactError))}">  
     <div class="recordError">  
       <ui:message title="Error" severity="error" closable="true">  
   <!-- Display the new contact form -->  
   <lightning:input aura:id="contactField" name="firstName" label="First Name" value="{!v.simpleNewContact.FirstName}" required="true"/>  
   <lightning:input aura:id="contactField" name="lastname" label="Last Name" value="{!v.simpleNewContact.LastName}" required="true"/>  
   <lightning:input aura:id="contactField" name="title" label="Title" value="{!v.simpleNewContact.Title}" />  
   <lightning:input aura:id="contactField" type="phone" name="phone" label="Phone Number"   
            messageWhenPatternMismatch="The phone number must contain 7, 10, or 11 digits. Hyphens are optional."  
           value="{!v.simpleNewContact.Phone}" required="true"/>  
   <lightning:input aura:id="contactField" type="email" name="email" label="Email" value="{!v.simpleNewContact.Email}" />  
   <lightning:button label="Cancel" onclick="{!c.handleCancel}" class="slds-m-top--medium" />  
   <lightning:button label="Save Contact" onclick="{!c.handleSaveContact}" variant="brand" class="slds-m-top--medium"/>  

Controller code

   doInit: function(component, event, helper) {  
       "Contact", null, false,   
       $A.getCallback(function() {  
         var rec = component.get("v.newContact");  
         var error = component.get("v.newContactError");  
   handleSaveContact: function(component, event, helper) {  
     if(helper.validateContactForm(component)) {  
       component.set("v.simpleNewContact.AccountId", component.get("v.recordId"));  
       component.find("contactRecordCreator").saveRecord(function(saveResult) {  
         if (saveResult.state === "SUCCESS") {  
           var resultsToast = $A.get("e.force:showToast");  
             "title": "Contact Saved",  
             "message": "The new contact was created."  
   handleCancel: function(component, event, helper) {  

Helper code

   validateContactForm: function(component) {  
     var validContact = true;  
           var allValid = component.find('contactField').reduce(function (validFields, inputCmp) {  
       return validFields && inputCmp.get('v.validity').valid;  
     }, true);  
     if (allValid) {  
       var account = component.get("v.account");  

This component you can use in Account Object detail page layout, and then try creating a contact record.
There are few things to keep in mind before thinking to use to Data service,

  • Can't be use for multiple records or mass DML's
  • Only available in Lightning & Salesforce1
  • Not all objects are supported by Lightning Data Service, listed in the link

Installing Lightning CLI and Scanning #Salesforce Lightning Component Code

This blog post is about installing Salesforce Lightning CLI, and how to scan your lightning component code for javascript coding issues and lighting issues. 

Lightning CLI alerts you to specific issues related to LockerService. Issues that are flagged include incorrect Lightning components code, and usage of unsupported or private JavaScript API methods. Lightning CLI installs into the Heroku Toolbelt, and is used on the command line.

Salesforce Lightning CLI is Heroku toolbelt plugin, need to install Heroku toolbelt, Lightning CLI relieas on Heroku toolbelt, so if you don't have Heroku installed, please install from the below link.

After installing Heroku, open cmd, and login to Heroku, git bash doesn't have this option of login to heroku, so need to use cmd only.

After successfull installation of heroku, check for node and npm, and then check for the version of theirs, and then install Lighting CLI

Enter below command

heroku plugins:install salesforce-lightning-cli

You have successfully installed Lightning CLI now. Its time to run and scan your lightning component JS code now.
You can scan a Lightning component in one shot, or a single JS file, to scan enter below command

heroku lightning:lint  ...path-of-your-lightning-component

Here is how Lightning CLI shows the component code errors, 

Above snapshot shows, what you need to modify in the controller and helper code, as it only scans the JS files.

Important links

Thanks !
Hope it helps.

 .THIS .step2 {  
 .THIS .step3 {  
 .THIS .step4 {  
 .THIS .tooltip {  
   display: none;  
 .THIS .default {  

To use this component you need to create a test app

 <aura:application extends="force:slds">  
   <c:ProgressBar />   

We can add many more icons, you can find all over Here in Progress Indicator

Here is source code in github.

This blog post is all about thing to cover up before going for the exam.

The Salesforce Certified Data Architecture and Management Designer candidate has the experience, skills, and knowledge of:

  • Data modeling/Database Design o Custom fields, master detail, lookup relationships o Client requirements and mapping to database requirements 
  • Standard object structure for sales and service cloud o Making best use of Salesforce standard objects 
  • Association between standard objects and Salesforce license types 
  • Large Data Volume considerations o Indexing, LDV migrations, performance
  • Salesforce Platform declarative and programming concepts 
  • Scripting using those tools (Data loader, ETL platforms) 
  • Data Stewardship 
  • Data Quality Skills (concerned with clean data)

Overview : 
  • Content: 60 multiple-choice/multiple-select questions* (2-5 unscored questions may be added) 
  • Time allotted to complete the exam: 90 minutes (time allows for unscored questions) 
  • Passing Score: 67% 
  • Registration fee: USD 400, plus applicable taxes as required per local law 
  • Retake fee: USD 200
Here are some key study points to cover before going for the exam :

PK Chunking Header

Use the PK Chunking request header to enable automatic primary key (PK) chunking for a bulk query job. PK chunking splits bulk queries on very large tables into chunks based on the record IDs, or primary keys, of the queried records. Each chunk is processed as a separate batch that counts toward your daily batch limit, and you must download each batch’s results separately. PK chunking is supported for the following objects: Account, Campaign, CampaignMember, Case, Contact, Lead, LoginHistory, Opportunity, Task, User, and custom objects. PK chunking works only with queries that don’t include SELECT clauses or conditions other than WHERE.
PK chunking is designed for extracting data from entire tables, but you can also use it for filtered queries. Because records could be filtered from each query’s results, the number of returned results for each chunk can be less than the chunk size. Also, the IDs of soft-deleted records are counted when the query is split into chunks, but the records are omitted from the results. Therefore, if soft-deleted records fall within a given chunk’s ID boundaries, the number of returned results is less than the chunk size.

Multitenancy and Metadata 

Multitenancy and Metadata Overview 
Multitenancy is a means of providing a single application to multiple organizations, such as different companies or departments within a company, from a single hardware-software stack. Instead of providing a complete set of hardware and software resources to each organization, Salesforce inserts a layer of software between the single instance and each organization’s deployment. This layer is invisible to the organizations, which see only their own data and schemas while Salesforce reorganizes the data behind the scenes to perform efficient operations. Multitenancy requires that applications behave reliably, even when architects are making Salesforce-supported customizations, which include creating custom data objects, changing the interface, and defining business rules. To ensure that tenant-specific customizations do not breach the security of other tenants or affect their performance, Salesforce uses a runtime engine that generates application components from those customizations. By maintaining boundaries between the architecture of the underlying application and that of each tenant, Salesforce protects the integrity of each tenant’s data and operations

Skinny Tables 

Salesforce creates skinny tables to contain frequently used fields and to avoid joins, and it keeps the skinny tables in sync with their source tables when the source tables are modified. To enable skinny tables, contact Salesforce Customer Support. For each object table, Salesforce maintains other, separate tables at the database level for standard and custom fields. This separation ordinarily necessitates a join when a query contains both kinds of fields. A skinny table contains both kinds of fields and does not include soft-deleted records. This table shows an Account view, a corresponding database table, and a skinny table that would speed up Account queries.
  • Skinny tables can contain a maximum of 100 columns. 
  • Skinny tables cannot contain fields from other objects. 
  • For Full sandboxes: Skinny tables are copied to your Full sandbox organizations, as of the Summer '15 release. Previously, they were not. 
For other types of sandboxes: Skinny tables are still not copied to your sandbox organizations. To have production skinny tables activated for sandbox types other than Full sandboxes, contact Salesforce Customer Support.


The Salesforce multitenant architecture makes the underlying data table for custom fields unsuitable for indexing. To overcome this limitation, the platform creates an index table that contains a copy of the data, along with information about the data types. The platform builds a standard database index on this index table, which places upper limits on the number of records that can be returned more effectively by an indexed search. Bulk API

The REST-based Bulk API was developed specifically to simplify the process of uploading large amounts of data. It is optimized for inserting, updating, upserting, and deleting large numbers of records asynchronously by submitting them in batches to, to be processed in the background.
Uploaded records are streamed to to create a new job. As the data rolls in for the job it is stored in temporary storage and then sliced up into user-defined batches (max of 10,000 records). Even while your data is still being sent to the server, the platform submits the batches for processing.

Using the Bulk API and Monitoring Jobs

The Data Loader v17 supports the Bulk API so it's easy to get started upload large datasets. Your user profile must have the "API Enabled" permission selected so if you are a System Administrator, you are all set. To get started, open up the Data Loader and edit the settings for the Bulk API.

Custom Notifications with Platform Events Beta Winter'17 #Salesforce

 The platform provides an event-driven messaging architecture to enable apps to communicate inside and outside of Salesforce. Use platform events to deliver secure and scalable custom notifications within Salesforce or from external sources.

Platform Events uses event-driven (or message-driven) software architecture.
In the event driven architecture there are event consumers, event producers and channels.
Event Producers produce the event and the event are performed in real time by consumers, and the event passes through the channel. Multiple events can be produced and passed through the channel and consumed by consumers.

Here is diagram for more clearance, source Salesforce

Lets talk real now,  this Platform events can be used for sending event from salesforce or outside. For example like event of door opening and closing of a lift, and if it doesn't opens then create case.

So to handle these event in multpile ways and to process or execute these events, Salesforce has given many ways for example we can build these events using process builder and execute using flows. 
In the same way we can have apex triggers on Platform events to handle exceptions, there are few new methods have been provided by salesforce specifically for Platform Event.

Now its time for example, login to your salesforce and in quick find box, search for Platform Event
Click on new New Platform Event.

Here is one I've created 

Here I am giving an example of writing trigger and webservice on Platform Event and executing them in salesforce.

Below is the apex trigger on Platform Events, on After insert event which will check for the door open and closed value using the is_Closed__c field. if the door is closed then it will throw the exception, for exception in the Platform event, Salesforce has introduced Event.RetryableException is property to check how many times the trigger has been retried, if failed then you can perform other actions.

//Trigger on 
trigger EventTrigger on Open_Door__e ( after insert ) {

    for(Open_Door__e odEvent : {
        //check for gate is open 
        if(odEvent.Is_Closed__c == false) {
            //Allowed to go in
        } else {
//exception to try event less then 4 times
            if (EventBus.TriggerContext.currentContext().retries < 4) {
                // Condition isn't met, so try again later.
                throw new EventBus.RetryableException( 'HOLD THE DOOR, HODORRRR.....!!');

Now as we discussed the Platform events can be called or executed from outside salesforce using webservices, so here we will publish a new event using webservice, for publishing an event also we have a method called EventBus.publish().
Below we are publishing the event

global class DoorOpenAndClosedEvent {

    webService static void checkForDoors(Boolean isClosed) {

        //Check for closed door
        if(isClosed) {
            List<Open_Door__e> odEvent = new List<Open_Door__e>();
            odEvent.add(new Open_Door__e(Is_Closed__c=false, Working_Properly__c=true));
            //publish events
            List<Database.SaveResult> results = EventBus.publish(odEvent);
            // Inspect publishing result for each event
            for (Database.SaveResult sr : results) {
                for(Database.Error err : sr.getErrors()) {
                    System.debug('Error returned: ' +  err.getStatusCode() + ' - ' + err.getMessage());

Now execute the method in console
After running the method, go to the platform event where we have created, and down below we will see how it got published, by checking the below table, it show it give you status, published ID.

Status can be different,  Trigger states can be one of the following.

This is a small tutorial of using this newly delivered Platform Event. Soon will get to know the power of this object.

Key Points about Platform Events

  • A platform event is a special kind of Salesforce entity, similar in many ways to an sObject.
  • You cannot update or insert Platform Events.
  • event publishing is equivalent to a DML insert operation, DML limits and other Apex governor limits apply.
  • You can use any Salesforce API to create platform events, such as SOAP API, REST API, or Bulk API.

Get Started with Setup of SalesforceDX, using Salesforce DX CLI #sfdx

Summer ’17 contains a beta release of Salesforce DX, Salesforce DX provides you with an integrated, end-to-end lifecycle designed for high-performance agile development. And best of all, we've built it to be open and flexible so you can build together with tools you love.

So here we are going to start the setup of SalesforceDX

Step 1 : Create SalesforceDX trial org or Salesforce Dev Hub Trial Org, here is the link

Step 2 : Enable the Dev hub in your org, perform below steps

Step 3 : Create a SalesforceDX user or you can use System admin user also, if your user is not a System admin, then create a permission set and assign the permission set to the salesforceDX user, permission set will have below permissions

Step 4 : Install SalesforceDX CLI

here is the link to download
After downloading the SalesforceDX CLI, install it.

After installing, it will by itself uninstall the git and re-install it again.

Step 5 : Use the sfdx-simple git repo, 

here is the link , we will get this repo in our system first, so clone it, follow below steps
Our first goal is to set up a developer project which we'll use to modify our application. It starts by cloning the repository. Use the command

             git clone

Then, open the directory.

             cd sfdx-simple

Step 6 : Login to SalesofrceDX

Run this command, it will install the NodeJS by itself as it requires NodeJs, and by this command we are login in to SalesforceDX org, and authorizing it.

So after this login window will open, where you need to put your salesforceDX credentials, and authorize, after that you can close the window

Step 7 : Now we will create a scratch org,

The scratch org is also created through the CLI, using a config file.
Run below command


              sfdx force:org:create -s -f config/project-scratch-def.json

So if you logged in the SalesforceDX org, you can see the data in Scratch org info. You are done as you've successfully created the scratch org.

Now, Push the repo metadata to scratch


       sfdx force:source:push

In the same way you can perform multiple actions using SalesforceDX CLI
to see more commands, enter


     $ sfdx force --help

Below are some commands you can use to create the metadata

To create apex class

        sfdx force:apex:class:create -n myclass

There are many things that we can do using SalesforceDX and SalesforceDX CLI, like continuos integration, source control and many more, soon will post about Salesofrce IDE 2, which can be used as of the important tool to leverage the functionality of SalesforceDX.

Using ui:collapse in Lightning Component #Salesforce

Here I am going to use ui:collapse, if you trying to add a functionality of hover or Accordion this can be a big help, here we are using ui:collapse , ui:menu, ui:menutriggerLink in which we have some child functions also, You can handle this event in a ui:menuList component instance. This example shows a menu component with two list items. It handles the ui:collapse and ui:expand events.
So here it is, you will have one or two link like below, on the click of which user will have a hover where by ui:actionmenuitem we can call other functions.

And using ui:collapse and other tags, we can achieve this

To achieve the above look and feel and the functionality

Here is the component code of the lightning component,

<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" access="global" >
    <aura:registerEvent name="menuCollapse"  type="ui:collapse" description="The event fired when the menu list collapses." />
            <div class="accordion">
                    <ui:menuTriggerLink aura:id="trigger" label="Contacts"/>
                    <ui:menuList class="actionMenu" aura:id="actionMenu" menuCollapse="{!c.addMyClass}" menuExpand="{!c.removeMyClass}">
                        <div class="accordion">
                            <p>sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
                            <ui:actionMenuItem aura:id="item1" label="Go to Contacts" click="{!c.doSomething}"/>
            <div class="accordion">
                    <ui:menuTriggerLink aura:id="trigger" label="Acounts"/>
                    <ui:menuList class="actionMenu" aura:id="actionMenu" menuCollapse="{!c.addMyClass}" menuExpand="{!c.removeMyClass}">
                        <div class="accordion">
                            <p>aliquip ex ea commodo consequat.</p>
                            <ui:actionMenuItem aura:id="item1" label="Go to Accounts" click="{!c.doSomething}"/>

Here is the controller

    addMyClass : function(component, event, helper) {
        var trigger = component.find("trigger");
        $A.util.addClass(trigger, "myClass");
    removeMyClass : function(component, event, helper) {
        var trigger = component.find("trigger");
        $A.util.removeClass(trigger, "myClass");


Here is css code

.THIS .accordion {
    background-color: #eee;
    color: #444;
    cursor: pointer;
    padding: 18px;
    width: 100%;
    border: none;
    text-align: left;
    outline: none;
    font-size: 15px;
    transition: 0.4s;

.THIS .accordion:hover {
    background-color: #ddd; 

Now to test, create one sample app and preview it.

Hope it helps, feel free ask any queries.
Thank you!
