Salesforce LWC Editor in browser

Salesforce made a great move by making the Web Components part of the eco system by introducing Lightning Web Component(LWC). But for some reason, they decided not to provide the ability to code it directly from their developer console. Currently the only way to do it is, is by using the VS Code. This is great, but if you’re in a hurry and want to make some quick changes, it won’t be easy.

To resolve this, I decided to make a quick-to-use LWC editor in my chrome extension Salesforce Advanced Code Searcher.

How to use:

  1. Install the extension by going to : https://chrome.google.com/webstore/detail/salesforce-advanced-code/lnkgcmpjkkkeffambkllliefdpjdklmi
  2. Navigate to your salesforce setup Page. You should see a “Click here to authorize” button. Click on it to authorize the extension.

3. Once the authorization is complete, Navigate to the LWC Editor tab and you should see all the Components that already exists in the Org. In case there are none then you can start by creating one.

What can you do?

  1. You can edit the components and save it back.

Look for the extension that you are looking for in the left file explorer, click open the link and that should open the file in a new tab. Make the required changes and hit Ctrl+s (PC) or Cmd +s (Mac) to save the change. In case there are errors it will be displayed in the console log right below the editor.

2. You can add a file in an existing components.

Right-click on the component where you want to add a file. You will be presented with 2 options : New File & Delete. Click on the New File to open a modal dialog where you can key in the file name (do not add an extension). Click on the Create File button and it will add the file under the component.

3. You can delete the files in the component.

5. You can also change the theme:

c3 charts and LWC

I wanted to try out some charting on LWC and I thought what better framework than C3. In this post we will see a component which will display opportunities in various statues associated to an account.

accountCHart

As a prerequisite you would need c3 and d3 (c3 has a dependency on d3.js) framework loaded in static resource for the charting to work .

Download the latest version of the C3 and D3 from below.

C3 -> https://github.com/c3js/c3/releases/latest

D3 -> https://github.com/d3/d3/releases/download/v5.9.7/d3.zip

Couple of important points for charting:

  1. Load the dependency in the same order that I mentioned below. D3 first and then follow it up with C3.
  2. We have added the a parameter t and assigned the current time to it.
    This is done to make sure the cache is refreshed every time the scripts are loaded.
    If we do not do this then there is an issues if we add multiple charts in a single component.
<template>
<!–Render the chart only when the opportunity data is available.–>
<template if:true={opportunityData}>
<!–We need not have another component for chart,
I thought it would be a better idea seperate out the charting component
for better readability–>
<c-opportunity-pie-chart chart-data={opportunityData}></c-opportunity-pie-chart>
</template>
</template>

import { LightningElement,api,wire,track } from 'lwc';
import opportunityAggregation from '@salesforce/apex/OpportunityDataService.aggregateOpportunities'
export default class OpportunityChartContainer extends LightningElement {
@api recordId; //As the component is loaded on a account detail page, we will get access to the account Id.
@track opportunityData=[];//Chart accepts data in multiple formats, array, object etc. We are using array here.
//get the data from the backend
@wire(opportunityAggregation,{accountId : '$recordId'}) opptyData({error, data}){
if(data){
let oppData = Object.assign({},data);
/*
this.opportunityData will in the below format
[['Closed Won',2],['Closed Lost',4],['Negotiation',5]];
*/
for(let key in oppData){
if(oppData.hasOwnProperty(key)){
let tempData=[key, oppData[key]];
this.opportunityData.push(tempData);
}
}
}
if(error)
console.log(error);
}
}

}
//destroy the chart once the elemnt is destroyed
disconnectedCallback() {

}
}

This is just a simple example for one to start with C3. Please share the beautiful charts that you build. Enjoy Charting!!!

LWC-Lightning Datatable sorting

This is a quick post to understand how sorting is accomplished in lightning datatable (LWC).

Lightning datatable provides an onsort attribute which will allow us to implement the sorting for the elements in the table. You could implement sorting locally or via making a server call.

Local Sorting

You would generally implement this type of sorting if you know that the list of elements is going to be small and limited. For example, if you’re displaying a list of approval history records for a particular record, you know that the number of records won’t be more (assuming you have a simple approval process).

In the example below, we have created a simple component which displays the list of the contacts (firstName and lastName). When the header column is clicked the onsort handler is invoked, the field and the sort order is passed and using this information the list is sorted.

<template>
<lightning-datatable
key-field="Id"
data={results}
columns={columns}
hide-checkbox-column ="false"
show-row-number-column="true"
onsort={updateColumnSorting}
sorted-by={sortBy}
sorted-direction={sortDirection}
row-number-offset ="0" >
</lightning-datatable>
</template>

import { LightningElement,track,wire } from 'lwc';
import fetchContact from '@salesforce/apex/ContactList.fetchContactLocal';
const dataTablecolumns = [{
label: 'First Name',
fieldName: 'FirstName',
sortable : true,
type: 'text'
},
{
label : 'Last Name',
fieldName : 'LastName',
type : 'text',
sortable : true
}]
export default class ContactListLocalSort extends LightningElement {
@track results=[];
@track columns = dataTablecolumns;
@track sortBy='FirstName';
@track sortDirection='asc';
@wire(fetchContact) contactList({error, data}) {
if(data)
this.results=Object.assign([], data);
if(error)
console.log(error);
}
updateColumnSorting(event){
let fieldName = event.detail.fieldName;
let sortDirection = event.detail.sortDirection;
//assign the values
this.sortBy = fieldName;
this.sortDirection = sortDirection;
//call the custom sort method.
this.sortData(fieldName, sortDirection);
}
//This sorting logic here is very simple. This will be useful only for text or number field.
// You will need to implement custom logic for handling different types of field.
sortData(fieldName, sortDirection) {
let sortResult = Object.assign([], this.results);
this.results = sortResult.sort(function(a,b){
if(a[fieldName] < b[fieldName])
return sortDirection === 'asc' ? 1 : 1;
else if(a[fieldName] > b[fieldName])
return sortDirection === 'asc' ? 1 : 1;
else
return 0;
})
}
}

Sorting via server call

As you would have guessed this would be useful when you have a huge list and you are displaying a small chunk of the total records.

The major advantage of this method is that you need not implement any custom logic at all. The sorting will be completely handled by the SOQL. Another thing to note here is that you will have to disable the data-table so that the user’s do not click on the header in the time the server call is being executed.

<template>
<lightning-datatable
key-field="Id"
data={results}
columns={columns}
hide-checkbox-column ="false"
show-row-number-column="true"
onsort={updateColumnSorting}
sorted-by={sortBy}
sorted-direction={sortDirection}
row-number-offset ="0" >
</lightning-datatable>
</template>

import { LightningElement,track,wire } from 'lwc';
import fetchContact from '@salesforce/apex/ContactList.fetchContact';
const dataTablecolumns = [{
label: 'First Name',
fieldName: 'FirstName',
sortable : true,
type: 'text'
},
{
label : 'Last Name',
fieldName : 'LastName',
type : 'text',
sortable : true
}]
export default class ContactListServerSort extends LightningElement {
@track results=[];
@track columns = dataTablecolumns;
@track sortBy='FirstName';
@track sortDirection='asc';
//since we have used the dynamic wiring,
//the list is automatically refreshed when the sort direction or order changes.
@wire(fetchContact,{field : '$sortBy',sortOrder : '$sortDirection'}) contactList({error, data}) {
if(data)
this.results=Object.assign([], data);
if(error)
console.log(error);
}
updateColumnSorting(event){
let fieldName = event.detail.fieldName;
let sortDirection = event.detail.sortDirection;
//assign the values. This will trigger the wire method to reload.
this.sortBy = fieldName;
this.sortDirection = sortDirection;
}
}

Error: An object ‘customMetadata.record.md’ of type CustomMetadata was named in package.xml, but was not found in zipped directory

This issue pops up when we try to deploy the customMetadata from One Org to another . The process I followed was to retrieve the components from Dev using ANT and then deploy it to QA using ANT. Retrieval of the components worked without any issue, but the name with which the components were retrieved was wrong.

componentFailure

If we observe carefully we do not see the __mdt in the extracted metadata but the deploy method expects the metadata name to have ‘__mdt’

After Retrieve.

beforeRetrieve

Just ensure to modify the name of the custom metadata to add the ‘__mdt’ to the file name and that should do the trick.

beforeDeployment

Hope it helps!

MultiFile upload / Drag and drop Attachments

Attaching multiple files as attachments to records is a pain. Its takes lot of time plus lot of navigation. Today, I want to share a small piece of code that I have written as home page component which will inject a small section in the ‘Notes and Attachments’ related list which will allow the users to load multiple file either selecting it from the input file selection or the users can drag and drop the files.

dragndrop

So how do you implement this in your org.

1) Add the main script to a js file and add it to static resource.

2) Create a new Custom Link.

3) Reference the js file in the custom link you created in the previous step. We will also need jQuery, so we will add that as well.

4) Add that custom link a home page component of type Links.

5) Add the home page component to the home page layout and you’re done. For more details on this hacking method, you can check this link here

So here we go: ->

1) Create a javascript file with the below code and add it as a static resource with the name attachmentjs

jQuery(function(){

    /*Checks when the notes and attachment section is loaded and then initiates the process.*/
    var timeInterval = setInterval(function(){
        if(jQuery("div.bRelatedList[id$=RelatedNoteList]").find("div.pbHeader").find("td.pbButton").find("input[name=attachFile]").length > 0){
            addAttachButton();
            clearInterval(timeInterval);
        }
    },100);


});

/*Adds the drop zone div in the notes and attachment section. Event listener are added to listen when files are dropped in the zone.*/
function addAttachButton() {

    var attachmentDiv = jQuery("div.bRelatedList[id$=RelatedNoteList]");
    insertButton();

    attachmentDiv.find("div.pbHeader").find("td.pbButton").after(
        jQuery("<td>", {
            style   : "width:35%;cursor:pointer;"
        }).append(jQuery("<div>",{
                style : "height: 30px;  width: px;border-color: orange;border: 3px solid orange;border-style: dotted;border-radius: 4px;text-align: center;vertical-align: middle;line-height: 2;color: Red;font-family: monospace;font-size: 14px;",
                id : "dropDiv"
            }).append(jQuery("<span>",{id:"clickHere"}).text('Drop files here / click here!') , jQuery("<span>",{id:"uploadingMessage",style:"display:none;"}).text('Uploading your Files, please wait!'))
        )
    );

    jQuery("#dropDiv").on('click',function(){
        if(jQuery("#uploadingMessage:hidden").length > 0) {
            if(jQuery("#multiUploadButton").length > 0) {
                jQuery("#multiUploadButton")[0].click();
            }else {
                insertButton();
                jQuery("#multiUploadButton")[0].click();
            }
        } else {
            alert('Your files are being uploaded. Please Wait!');
        }
    });

    function handleFileSelect(evt) {
        evt.stopPropagation();
        evt.preventDefault();
        var files = evt.dataTransfer.files; // FileList object.
        processFiles(files);
    }    
    function handleDragOver(evt) {
        evt.stopPropagation();
        evt.preventDefault();
        evt.dataTransfer.dropEffect = 'copy'; // Explicitly show this is a copy.
    }

    var dropZone = document.getElementById('dropDiv');
    dropZone.addEventListener('dragover', handleDragOver, false);
    dropZone.addEventListener('drop', handleFileSelect, false);
}


function processFiles(files) {
    hideDiv();
    var insertedFilesArray = [];
    var fileInsertionCounter = 0;

        for(i=0;i<files.length;i++) {
                    
            var reader = new FileReader();
            reader.onload = (function(newFile,pId) {
                return function(e) {
                    var attachmentBody = e.target.result.substring(e.target.result.indexOf(',')+1,e.target.result.length);
                        
                    jQuery.ajax({
                        type: "POST",
                        url: "https://"+window.location.host+"/services/data/v33.0/sobjects/Attachment/",

                        headers: { 
                            "Authorization" : "Bearer "+getCookie('sid')
                        },
                        data    : JSON.stringify({'name':newFile.name,'body':attachmentBody,'parentId':pId,'isprivate':false})
                    }).success(function(result) {
                        fileInsertionCounter++;
                        if(fileInsertionCounter == files.length){
                            showDiv();

                        alert('Unable to Insert file \n Contact your Adminstrator with this error message \n' + JSON.stringify(err));
                        fileInsertionCounter++;
                        //if all the files are uploaded then show the zone div.
                        if(fileInsertionCounter == files.length){
                            showDiv();
                        }
                    });
                };
            })(files[i],jQuery("div.bRelatedList[id$=RelatedNoteList]").attr('id').split('_')[0]);
            
            reader.readAsDataURL(files[i]);
        }
}

/*Inserts the input file button. This is hidden from the view.*/
function insertButton() {
    if(jQuery("#multiUploadButton").length == 0) {
        var attachmentDiv = jQuery("div.bRelatedList[id$=RelatedNoteList]");
        attachmentDiv.find("div.pbHeader").find("td.pbButton").append(
            jQuery("<input>",
                {id     : "multiUploadButton",
                value   : "Multiple Upload",
                type    : "file",
                multiple: "multiple",
                style   : "display:none;"
                })
        );
        jQuery("#multiUploadButton").on('change',function(){
            processFiles(document.getElementById("multiUploadButton").files);
        });
    }
}

function hideDiv() {
    jQuery("#uploadingMessage").show();
    jQuery("#clickHere").hide();
}

function showDiv() {

    jQuery("#uploadingMessage").hide();
    jQuery("#clickHere").show();
    RelatedList.get(jQuery("div.bRelatedList[id$=RelatedNoteList]").attr('id')).showXMore(30);
}

function getCookie(c_name){
    var i,x,y,ARRcookies=document.cookie.split(";");
    for (i=0;i<ARRcookies.length;i++){
        x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
        y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
        x=x.replace(/^\s+|\s+$/g,"");
        if (x==c_name){
            return unescape(y);
        }
    }
}

2) Create a custom link called ‘Attacher Custom Link’ and the add the below code. Make sure you select Behaviour as ‘Execute Javascript’.

  {!REQUIRESCRIPT('//code.jquery.com/jquery-2.1.3.min.js')}
  {!REQUIRESCRIPT('/resource/attachmentjs')}

… follow all the steps mentioned above and you should be set. I have tested this on Latest Chrome and firefox browsers and this is working just fine.

Showing a VF in jQuery modal dialog on standard page button click

Showing a VF page as a popup on click of a custom button is fairly easy. But the problem arises when we have to refresh the parent when the user has completed the operation on the VF pop-up page because of the same-origin policy. The browser doesn’t allow any communication across domain/ protocol. But as a workaround we can use the postMessage() to communicate between parent and pop-up window even if they are on different domain, but again IE8 doesn’t support this.

jQuery Modal Dialog to the rescue. In this demo we will place a custom button on the account detail page, clicking on which will pop-up a modal-vf page which will allow the user to update the name of the account.

I will be using 4 components to demo this :

1) A javascript file, stored in Static resource
2) An images zip file in static Resource. Click here to download the images zip file and store it in the static resource by the name images
3) A Custom button
4) An apex class (extension)
5) A VF page (pop-up)

Lets start with the javascript file. Store this in the static resource by the name mainjs

	/*@description: This script will insert a modal div in the standard page.
					the modal will contain a VF page. This file should be located in static resource.*/
	var j$ = jQuery.noConflict();
	var currentUrl = window.location.href;
	var hostIndex = currentUrl.indexOf(window.location.host+'/')+(window.location.host+'/').length;
	var accountId = currentUrl.substring(hostIndex,hostIndex+15); 
	j$(function(){
		/*Insert the jQuery style sheets in the Head.*/
		/*Insert the Modal dialog along with the VF as an iframe inside the div.*/
		j$("head").after(
			j$("<link>",{rel:"stylesheet",
						href:"https://code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css"}));
		j$("body").after(
			j$("<div>",{id:"modalDiv",
					    style:"display:none;"
			   }).append(
				j$("<iframe>",{id:"vfFrame",
							 src:"/apex/popuppage?id="+accountId,
							 height:200,
							 width:550,
							 frameBorder:0})
			   ));
		/*Initialize the Dialog window.*/
		j$("#modalDiv").dialog({
			autoOpen: false,
			height: 210,
			width: 605,
			modal:true
		});
	});

Apex Class :

public class PopUpExtension{
    public Account account{get;set;}

    public PopUpExtension(ApexPages.StandardController stdController){
        this.account = (Account)stdCOntroller.getRecord();
    }
    
    public void saveAccount() {
        try{
            update Account;
        }catch(exception e) {
            ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR,'Error Occured while updating the account '+e.getMessage());
            ApexPages.addMessage(myMsg);
        }
    }
}

VF page, name it as popuppage:

<apex:page showHeader="false" sidebar="false" standardController="Account" extensions="PopUpExtension">
    <apex:form>
        <apex:pageBlock title="{!Account.Name}" id="pageBlock">
            Update the Account Name:<br/>
            <b>Account Name</b><apex:inputField value="{!Account.Name}"/>
            <apex:commandButton action="{!saveAccount}" value="Save" onComplete="closeAndRefresh();" status="actionStatus" reRender="pageBlock"/>
            <apex:actionStatus id="actionStatus">
                <apex:facet name="start"> 
                    <img src="/img/loading.gif"/>
                </apex:facet>
            </apex:actionStatus>
        </apex:pageBlock>
    </apex:form>
    <script>
        function closeAndRefresh(){
            console.log('clicked on the button');
            window.top.location = '/{!$CurrentPage.parameters.id}';
        }
    </script>
</apex:page>

Finally create a button on the Account and call it jQuery modal. Select
‘Detail Page Button’ as the Display Type ,
‘Execute Javascript’ as the Behavior and
‘onClick JavaScript’ as content source.

Add the below code in the button:

{!REQUIRESCRIPT("https://code.jquery.com/jquery-1.10.2.js")} 
{!REQUIRESCRIPT("https://code.jquery.com/ui/1.10.4/jquery-ui.js")} 
{!REQUIRESCRIPT("/resource/mainjs")}

j$("#modalDiv").dialog('option','title','{!Account.Name}').dialog('open');

Hope this helps!

Generate a PDF and Attach it to record from a trigger in Salesforce — RESTful Webservice

Attaching the PDF using RESTful services.

I have posted an article on the step-by-step instruction on doing the same the SOAP way.

Here you go:
Step 1: create a REST resource class and in the post method add the logic to generate the PDF
Step 2: Create a class which has future Method (with callout=true). This future method will call the REST Resource
Step 3: Finally create a trigger that will call this future method.

In this scenario I will create a account and a pdf will be attached to it after the insert.

First lets create the VF page to generate the pdf, a simple one. Lets call it, pdfRenderPage


<apex:page standardController="Account" renderAs="pdf">

Hey, the Account name is {!account.Name}

</apex:page>

Create the Rest Resource which will insert the pdf attachement.

@RestResource(urlMapping='/addPDFtoRecord/*')
global with sharing class AddPDFtoRecordREST{
  
  @HttpPost
    global static void doPost(list<String> accountIdList) {
       list<attachment> insertAttachment = new list<attachment>();
        for(String accId: accountIdList){
            //create a pageReference instance of the VF page.
            pageReference pdf = Page.pdfRenderPage;
            //pass the Account Id parameter to the class.
            pdf.getParameters().put('id',accId);
            Attachment attach = new Attachment();
            Blob body;
            if(!test.isRunningTest()){
                body = pdf.getContent();
            }else{
                body=blob.valueOf('TestString');
            }
            attach.Body = body;
            attach.Name = 'pdfName'+accId+'.pdf';
            attach.IsPrivate = false;
            attach.ParentId = accId;//This is the record to which the pdf will be attached
            insertAttachment.add(attach);
         }
         //insert the list
         insert insertAttachment;
    }
}

Next create a class with the future method:

global class AccountTriggerController{

    @Future(callout=true)
    public static void addPDFAttach(string sessionId, list<id> accountIdList){
       HttpRequest req = new HttpRequest();
       req.setEndpoint('https://'+URL.getSalesforceBaseUrl().getHost()+'/services/apexrest/addPDFtoRecord/');
       req.setMethod('POST');
       req.setBody('{"accountIdList":'+JSON.serialize(accountIdList)+'}');
       req.setHeader('Authorization', 'Bearer '+ sessionId);
       req.setHeader('Content-Type', 'application/json');
       Http http = new Http();
       if(!test.isRunningTest()){
           HTTPResponse res = http.send(req);
       }
    }
}

FInally create the trigger:

trigger accountAfterInsert on Account (after insert) {

     list<id> accId = new list<id>();
     for(id acc: trigger.newMap.keySet()){
         accId.add(acc);
      }
		//You would need to send the session id to the future method as the you cannot use the userInfo.getSessionID() method in the future method because it is asynchronous and doesn't run in the user context.
        AccountTriggerController.addPDFAttach(userInfo.getSessionId(), accId);

}

All of this would work only if you add the host in my case it’s https://ap1.salesforce.com, add it to the remote site setting. So go to Setup-> Admin Setup -> security Controls -> Remote Site Settings. Click on new, give it a name(RESTTest), add the Remote Site URL(just copy paste the url from the address bar), it will only take the host and truncate the rest when you save it.

Test Class:

@isTest
public class AddPDFtoRecordTest{
    @isTest static void addPDFtoRecordTestMethod() { 
        account a = new account();
        a.name= 'test PDF';
        insert a;
        
        List<String> accountIdList = new List<String>();
        accountIdList.add(a.Id);
        RestRequest req = new RestRequest(); 
        RestResponse res = new RestResponse();
    
        req.requestURI = 'https://'+URL.getSalesforceBaseUrl().getHost()+'/services/apexrest/addPDFtoRecord/';  
        req.httpMethod = 'POST';
        req.requestBody = Blob.valueOf('{"accountIdList":'+JSON.serialize(accountIdList)+'}');
        req.addHeader('Content-Type', 'application/json');
        RestContext.request = req;
        RestContext.response = res;
    
        AddPDFtoRecordREST.doPost(accountIdList);              
    }
}

You can find the code on gitHub

Hiding selected Side bar custom components(HTML)

There are times in the project where we have to have some UI changes done on the Standard pages. For example, you may have to change the label of the ‘open Activities’ related list on a particular object’s standard page. To achieve this functionality we usually write a simple javascript / jquery script in the side bar component (of type HTML) and then that will do the work. So there are scenarios where multiple team might have implemented such functionality and this results in a lot of sidebar components showing up on the UI which will not make sense to the End Users

In the below code one have to just enter the name of the such side bar components and then that side bar component will be automatically hidden.

//Referencing the jQuery library from the static resource
<script src="/resource/jQuerylib"></script>
<script>
	
var j$ = jQuery.noConflict();
//Add All the name of the components that you want to hide.
var hideComponentArray = ['component1','component2','HideSideBarComponents'];
j$(function(){
   j$("h2.brandPrimaryFgr").each(function(){
      if(j$.inArray(j$(this).text(), hideComponentArray) != -1){
         //Hiding the entire div.
         j$(this).parent("div.sidebarModuleHeader").parent("div.htmlAreaComponentModule").hide();
      }
    });
});
</script>

Uploaded my first salesforce extension on Chrome store

I have finally managed to upload my chrome extension which will help developers to search a string in their code.

You can download it from here:

https://chrome.google.com/webstore/detail/salesforce-advanced-code/lnkgcmpjkkkeffambkllliefdpjdklmi

A similar extension is also available on Mozilla as well. You can download it from here.
