Connecting to Salesforce using Pub / Sub API (gRPC)

pub / sub API is currently in pilot. Talk to your AE to have it enabled in your org. Below implementation may change once the features are GA.

Pub/Sub API has been the talk of the town for some and I got to play with it recently. There are some code example in the pub / sub API pilot documentation but that’s only available in Python. Being a Node.js enthusiast I wanted to establish the pub / sub api using node.js.

npm packages
jsforce -> To get the authentication details.
avro-js -> Converting the binary response from subscribe call to json & vice-versa
grpc -> Core GRPC library
@grpc/proto-loader -> This library is used to load the proto file.

// npm packages & initialization
const grpc = require("grpc");
const fs = require("fs");
const jsforce = require("jsforce");
const avro = require("avro-js");
const protoLoader = require("@grpc/proto-loader");
const packageDef = protoLoader.loadSync("sf.proto", {});
const grpcObj = grpc.loadPackageDefinition(packageDef);
const sfdcPackage = grpcObj.eventbus.v1;
const root_cert = fs.readFileSync("roots.cer");

Authenticating & connecting to Salesforce
As of now pub/sub api do not provide any method / rpc for authenticating the user. You will have to perform the login call using jsforce library or directly via rest api to get the details. The details that are required are
– accesstoken
– instanceurl
– orgid
The above details will be set as metadata headers and will be used to setup the initial connection with the grpc server.

const conn = new jsforce.Connection({
loginUrl: "",
const connectionResult = await conn.login(username, password);
const orgId = connectionResult.organizationId;
const metaCallback = (_params, callback) => {
const meta = new grpc.Metadata();
meta.add("accesstoken", conn.accessToken);
meta.add("instanceurl", conn.instanceUrl);
meta.add("tenantid", orgId);
callback(null, meta);
const callCreds = grpc.credentials.createFromMetadataGenerator(metaCallback);
const combCreds = grpc.credentials.combineChannelCredentials(
const client = new sfdcPackage.PubSub(

Topic Info & Schema Info
Salesforce transmits the data in avro binary format. To read this format we would need the schema information to convert the binary to readable json format. The salesforce proto file provides 2 rpc for the same.
GetTopic -> Pass the topic name (Platform event or CDC name) to get the schemaId. This schemaId will be passed to the GetSchema rpc to get the actual schema.
GetSchema -> Pass the schema Id retrieved in the previous GetTopic call to get the schema which will be used for avro conversion.

const topicName = '/event/Your_Custom_event__e';
let schemaId = '';
let schema;
client.GetTopic({ topicName: topicName }, (err, response) => {
if(err) {
//throw error
}else { //get the schema information
schemaId = response.schemaId
client.GetSchema({ schemaId: schemaId }, (error, res) => {
if(error) {
//handle error
}else {
schema = avro.parse(res.schemaJson)

Now that we all the prerequisites , let do the actual thing, subscribing to a platform event. One thing to note here is that both the input & output of the Subscribe rpc are streams (BiDirectional Stream).

const subscription = client.Subscribe(); //client here is the grpc client.
//Since this is a stream, you can call the write method multiple times.
//Only the required data is being passed here, the topic name & the numReqested
//Once the system has received the events == to numReqested then the stream will end.
topicName: "/event/Your_platform_event__e",
numRequested: 10,
//listen to new events.
subscription.on("data", function (data) {
console.log("data => ", data);
// is an array of events. Below I am just parsing the first event.
//Please add the logic to handle mutiple events.
if ( {
const payload =[0].event.payload;
let jsonData = schema.fromBuffer(payload);//this schema is the same which we retreived earlier in the GetSchema rpc.
console.log("Event details ==> ", jsonData);
} else {
//if there are no events then every 270 seconds the system will keep publishing the latestReplayId.
subscription.on("end", function () {
subscription.on("error", function (err) {
console.log("error", JSON.stringify(err)); //handle errors
subscription.on("status", function (status) {
console.log("status ==> ", status);

Publishing an event
For publishing an event salesforce’s proto offers 2 rpc (bidirectional stream & unary). We will use the unary rpc to publish an event.

const dataToPublish = {
Some_Text_Field__c: { string: "Test" },
Another_Boolean_Field__c: { boolean: false },
CreatedDate: new Date().getTime(), //This is Required
CreatedById: "0057X000003ilJfQAI", //Id of the current user. This is required.
topicName: "/event/Your_Custom_Event__e",
events: [
id: "124",// this can be any string
schemaId: schemaId, //This is the same schemaId that we retrieved earlier.
payload: schema.toBuffer(dataToPublish), //The schema here is the avro generated schema
function (err, response) {
if (err) {
console.log("error from publishing ", err);
} else {
console.log("Response ", response);

Hope it helps!

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 :
  2. Navigate to your salesforce setup Page. You should see a “Click here to authorize” button. Click on it to authorize the extension.
Image for post

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.

Image for post

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:

Running PMD against Apex & Triggers.

It is always a best practice to ensure you comply with the coding standards when you write your apex classes or triggers and you probably already make sure you do that. But how do you make sure to your entire team is complying to the coding standard, how do you make sure your team, your company is delivering the best to the client?

The answer to this is Static code analysis. There are n number of tools available in the market which will run the static code analysis against salesforce code base. Few of them:

  1. PMD
  2. Checkmarx
  3. Fortify

Both Checkmarx & fortify are paid whereas PMD is completely free of cost. The next question that comes to your mind: How do I run PMD against my code base?

Well, there are multiple options:

  1. You can download the executable, configure it, identify the rules and run it locally everytime you want to push the code to UAT or Production.
  2. You and your entire team installs the Apex PMD VScode plugin and this will throw the error everytime your code. But again apex can also be coded using dev console or other online IDEs like so you cannot always rely on your teammates to use Apex PMD.
  3. The simplest option, install the Salesforce Advanced Code searcher Chrome extension which once installed will allow you to run the PMD checks right inside your browser. It will spit out the results in an excel sheet which you can then analyze and assign to team members to fix. And this will work in sandboxes and Production org.

So, what are you waiting for?? Install the plugin and discover the mess your developers have created 🙂

P.S: This extension also allows you to run static code analysis against your aura components.

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>
var j$ = jQuery.noConflict();
//Add All the name of the components that you want to hide.
var hideComponentArray = ['component1','component2','HideSideBarComponents'];
      if(j$.inArray(j$(this).text(), hideComponentArray) != -1){
         //Hiding the entire div.

Uploaded another extension on Chrome : Salesforce code Coverage extractor

I have taken this extension out now.. Need to implement some changes. . Will be back up soon

This extension will help admin / developers to extract the overall code coverage from the developer console. All they have to do is hover over the Overall code coverage section and then click on the [Extract Data] link and then you have the csv downloaded. 

You can also extract SOQL and SOSL results in the same manner from the developer console.

You can get the extension here:

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:

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

Extracting list of all the objects (Standard + Custom) in Salesforce

Adding another category in blog today : “Just for kicks!!”, which is the reason for this post.

Today as I was whiling away hours, a thought struck my mind ‘Why not list out all the objects(which is quite simple) and their related objects(this was challenging) as well in a VF page’?

The reason listing the child object for each object was challenging is because salesforce(governer limits) only allows 100 childrelationship describes per apex invocation, as we already have more 100 objects in our org, doing child describes for each objects will result in more than 100 child relationship describe per invocation. As a workaround: I added a apex:actionFunction which will be fired every 2.5 seconds triggering a method in the class, so each time it is triggered it is considered as one invocation.


So here’s the code (save the class 1st and then the Page):

Passing sObjects to future methods in Salesforce

So how to pass sObject to future methods, even when we know that the future methods do not accept the sobjects. So how do we do it?
We will use the JSON methods to first serialize the list of account which will be serialized as string. This string is passed to the future method and then in the future method we will de-serialize the string back to list of account and insert the accounts.

Here’s the code;

This is the main class, we will call it GenerateJson

	public class GenerateJson{
    public GenerateJson(){
        // I have hardcoded the name and the account number in Kannada!! 
        account acc1 = new account(name = 'ಬೆಂಗಳೂರು', AccountNumber= '೧೦೨೯೩೭');
        account acc2 = new account(name ='ಹುಬ್ಬಳ್ಳಿ', AccountNumber= '೬೮೬೮೮೮೦');
        //Initialize a list of account
        list<account> accList = new list<account>();
        //Using the JSON.serializePretty we will serialize the list of account.
        string jsonString = JSON.serializePretty(accList);

        //Pass the serialized list to the future method.

We will create another class with a future method. We will name the class DeserializeJsonRecords

public class DeserializeJsonRecords{
    public static void insertAccount(string accountString){
        //Deserialize the list and cast it to account list.
        list<account> insertAccList =  (list<account>)JSON.deserializeStrict(accountString, list<account>.class);
		//Insert the accounts
        insert insertAccList;

To check if the code works just run the below line in the developer console

GenerateJson genJson = new GenerateJson();

One of the catch here is if the size of the list is very huge then there are chances that the heap size limit will be reached. Also I am not sure about how the the rich text area fields are deserialized, will need to test that.

Hope it helps!

Generate a PDF and Attach it to record from a trigger in Salesforce — SOAP webservice

The reason you stumbled upon this post is because you tried using the .getContentAsPdf() method in a trigger and you got an error message stating you cannot use it in a trigger. So you tried to search and figure out as to how you could do it.

I had faced a similar issue when a task was given to me attach a pdf(which would be automatically created) when a record is created. Inititally I thought its quite simple and accepted it. But when I actually started coding, I became aware of the issues with this requirement.

Well, I googled for a while and came across a post (unfortunately, I could not find it now) which had the solution to this problem, but the guy had not posted the code to demonstrate. So I thought I could share the code in a post as this could help someone.

Here you go:
Step 1: create a class and include a webservice method that will generate the pdf and attach it to a record
Step 2: Generate the WSDL from this class.
Step 3: Generate a class from the WSDL you just created. (step 2 and 3 are a little wierd, but believe me it works)
Step 4: Create a class which has future Method (with callout=true). This future method will call the stub which you just created from the WSDL.
Step 5: Finally create a trigger that will call this future method.

If you find any better way of doing this please do let me know.

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}


The webservice class, After you save this class, you can see a generate WSDL button. click on it and save the WSDL file

global class AddPdfToRecord{

    webservice static void addPDF(list<id> accountIds){
		//Instantiate a list of attachment object
        list<attachment> insertAttachment = new list<attachment>();
        for(Id accId: accountIds){
			//create a pageReference instance of the VF page.
            pageReference pdf = Page.pdfRenderPage;
			//pass the Account Id parameter to the class.
            Attachment attach = new Attachment();
            Blob body;
                body = pdf.getContent();
            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
		 //insert the list
         insert insertAttachment;

Now, consume the WSDL that you just generate. Go to Setup->App Setup-> Develop-> Apex Classes and click on Generate from WSDL. Load the WSDL file and name the class as ‘addPDFStub’.

//Generated by wsdl2apex

public class addPDFStub {

            request_x.accountIds = accountIds;
            Map<String, addPDFStub.addPDFResponse_element> response_map_x = new Map<String, addPDFStub.addPDFResponse_element>();
            response_map_x.put('response_x', response_x);
              new String[]{endpoint_x,
            response_x = response_map_x.get('response_x');

Next create a class with the future method:

global class AccountTriggerController{

    public static void addPDFAttach(string sessionId, list<id> accountId){
        addPDFStub.SessionHeader_element sessionIdElement= new addPDFStub.SessionHeader_element();
        sessionIdElement.sessionId = sessionId;

        addPDFStub.AddPdfToRecord stub= new addPDFStub.AddPdfToRecord();
        stub.SessionHeader= sessionIdElement;

FInally create the trigger:

trigger accountAfterInsert on Account (after insert) {

     list<id> accId = new list<id>();
     for(id acc: trigger.newMap.keySet()){
		//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, 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(webserviceTest), 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.

Hope it helps!!


I have updated the post with the test Classes. Now all the classes have more than 90% coverage!
ALso I have made some changes in the AddPdfToRecord class to accommodate the Test class changes
Below test classes needs to be added to get the coverage

First add the web service mock implementation and then the actual test class.

global class WebServiceMockImpl implements WebServiceMock {
   global void doInvoke(
           Object stub,
           Object request,
           Map<String, Object> response,
           String endpoint,
           String soapAction,
           String requestName,
           String responseNS,
           String responseName,
           String responseType) {
           String[] accountIdArray = new String[]{};
       addPDFStub.addPDFResponse_element respElement = new addPDFStub.addPDFResponse_element();
       addPDFStub.AllowFieldTruncationHeader_element class1= new addPDFStub.AllowFieldTruncationHeader_element();
       addPDFStub.DebuggingHeader_element class2= new addPDFStub.DebuggingHeader_element();
       addPDFStub.CallOptions_element class3= new addPDFStub.CallOptions_element();
       addPDFStub.DebuggingInfo_element  class4= new addPDFStub.DebuggingInfo_element ();
       addPDFStub.SessionHeader_element class5= new addPDFStub.SessionHeader_element();
       response.put('response_x', respElement ); 
public class AddPDFtoRecordTest{
    @isTest static void addPDFtoRecordTestMethod() { 
        Test.setMock(WebServiceMock.class, new WebServiceMockImpl());
        account a = new account(); 'test PDF';
        insert a;
        AddPdfToRecord.addPDF(new list<Id>{a.Id});    

YOu can achieve the same by using the APEX Rest Resource. Check out the post here

You can find the code on gitHub

Using jQuery’s AutoComplete in Salesforce – Part 2

In the first part we saw that we are using a static array to show the country value. This is of no use in real-time scenario. In most of the cases one will be required to show the values from some where else. So how do we do it in salesforce??

In this example we will use the account and contact object to get the data.
Now, there are 2 ways to get the data from the database.
1.) Use a controller, which will return you a list of accounts.
2.) Query directly in the VF page using the Salesforce’s Ajax toolkit.


I will demonstrate both the ways in the same code.

Step 1: Create an apex class with the below code. The name of the class is AutoCompleteDemoController
Step 2: Create a the VF page with the below code. Name the VF page : AutocompleteDemoPage

Apex Class:

public class AutoCompleteDemoController{
    public list<account> getAccountList(){
        return [select id,name from account limit 25];

VF page:

<apex:page controller="AutoCompleteDemoController">
    <!--Make sure you have the Javascript in the same order that I have listed below.-->
    <script src=""></script>
    <script src="/soap/ajax/26.0/connection.js" type="text/javascript"></script>
    <script src=""></script>
    <link rel="stylesheet" href=""/>
    <script type="text/javascript">
        var j$ = jQuery.noConflict();
        var apexAccountList =[];
        //use the <!-- <apex:repeat> -->tag to iterate through the list returned from the class and store only the names in the javascript variable.
        <apex:repeat value="{!accountList}" var="accList">
            //Store the name of the account in the array variable.
        //We will establish a connection salesforce database using the sforce.connection.init(sessionID, ServerURL) function.
        var sid = '{!$Api.Session_ID}';
        var server = "https://" + + "/services/Soap/u/26.0";
        sforce.connection.init(sid, server);
        //We will query the contact object using the sforce.connection.query function. This will return 200 results.
        var result = sforce.connection.query("select Name from Contact");
        var records = result.getArray("records");
        var javascriptContactList =[];
        //Iterate thru the list of contact and store them in a javascript simple array variable which will then assign it to the source of the autocomplete.
        //on Document ready
                source : apexAccountList
                source : javascriptContactList
        <b>Account(This uses the Apex class to display the list)</b><input type="text" id="apexaccountautocomplete"/><br/><br/>
        <b>Contact(This uses the salesforce's ajax toolkit to display the list)</b><input type="text" id="sfjscontactautocomplete"/>

P.S:This code may not work correctly in Google Chrome Browser initially.
Workaround: When you load the VF page for the 1st time in Chrome, you will see a shield (gray in color) in the address bar, click on it and select ‘Load unsafe javascript’. Another option is to load the script in the static resource and refer the scripts from there in the VF page.
