Gravatar – Reusable Lightning Web Component

Gravatar - Reusable Lightning Web Component

Wouldn’t it would be great if we can use existing avatar of user on basis of email id instead of asking user to upload their profile pic ?

Gravatar is Globally recognized avatar used by millions of user and many websites like WordPress, github, stackoverflow etc.

Click here for Live Demo – Gravatar Component on public community

In this post, we would create a reusable lightning component which would receive below three parameters to construct avatar

  1. Email address to render avatar
  2. Size of avatar
  3. Should image be rendered as rounded corner

Gravatar would need MD5 equivalent of email address. There is no native Javascript library to compute MD5 hash, either we have to use Javascript library or we can use Apex to compute MD5 using crypto class. I preferred Apex class instead of any other library a shown below

Salesforce Load Testing using SOAPUI

API Load Testing using SOAPUI

Previously, I have added multiple posts in this blog on how you would face governor limit errors on each step of Salesforce implementation and how we can leverage selenium to perform load testing of Salesforce to some extent.

SOAP UI is powerful tool and in this post we will see how it can be used to perform load testing of Salesforce API.

Step 1 : Download PartnerWSDL from your Salesforce instance and create SOAP UI Project.

Step 2 : Create a Test Suite in SOAP UI

Limitations of LWC

LWC Not Supported

Almost all of us started using LWC instead of Aura or Visualforce however there are multiple occasion where we need to come back to either Aura or Visualforce.

I was not able to find single consolidated list of limitations of LWC and therefore thought to post this blog.

Feel free to comment on this blog post and help me keep this updated.

Unsupported features of Lightning Web Components

Using Custom Label in Lightning Web Components – LWC

Below is code snippet on using custom labels in Lightning Web Components.

Assume, we have custom label named welcomeText and exitText

In Javascript file of LWC, we have to follow below syntax 

// CustomlabelExample.js
import { LightningElement } from 'lwc';
 
// Import custom labels
import welcomeText from '@salesforce/label/c.welcomeText';
import exitText from '@salesforce/label/c.exitText';


export default class CustomLabelExample extends LightningElement { 

    // Expose the labels to use in the template.
    label = {
        welcomeText,
        exitText
    };
}

Notice, how we imported label and used c. if there is no namespace. 

import welcomeText from '@salesforce/label/c.welcomeText';

<!-- CustomlabelExample.html -->
<template>
    Hi , {label.welcomeText} !!! 
   <!-- some more code --> 
   Sorry to see you going, {label.exitText}
</template>

Sharing records in partner community from different Accounts

Using Account Relationship Data Sharing Rule

As we know there are limited options to share records between community users.

For Customer Community , we can use Sharing set or Sharing Group.

For Customer Community Plus & Partner Community we can use role & Sharing rule. Maximum role that community can have is 3 per account and thats limitation there as well.

Now , lets assume below scenario

Salesforce Integration Patterns & Best Practices – with Video

Integration Patterns in Salesforce

Recently I gave talk in one of most active webinar of Salesforce ecosystem today – Apex hours on topic Integration Patterns and Best Practices in Salesforce.

Response was more than expected and questions were high quality. Therefore, I thought to quickly write high level summary of presentation in this blog post along with Youtube video that you can find towards the end of this post.

Firewall, Proxy and Reverse Proxy

Before integrating anything with Salesforce, as per Architect, it is necessary which system components are important for security and may impact with integration pattern to be used.

Firewalls : It controls and protects Malicious Traffics. Firewall can be hardware or software based.

Proxy aka Forward Proxy : Proxy normally configured in your browser or systems like VsCode, data loader, eclipse to hide your actual identity. Every outgoing request transmits through proxy server to make sure external systems unaware about your true origin and identity

Reverse Proxy : Its used by Web Servers and sits before it. It can server any purpose like authentication or perform security related stuff. Best example is Mulesoft where we can configure API proxy which is used to apply throttling, avoiding DoS attacks or applying SLA as per licenses provided to customer

Trailhead Challenge Errors & Solutions

Sometime Salesforce Trailhead Challenge requirement and actual solution doesn’t go hand in hand. And seems many others also face same issue , Thats why I would be making notes on how I fixed Trailhead challenge issue.

Note : I would not be sharing solutions of Trailhead challenge , I will post fix only when there is discrepancy in what’s being asked and what worked.

Setup Escalation and Entitlement

Solution to this challenge would not work if you have Person Account enabled in Org. Try solution in non Person Account Org.

Error : The second Block Price for the Mobile Control Center App is not configured correctly. Check the Lower Bound, Upper Bound, and Price.

Pricing Methods for Salesforce CPQ – Implement Block Pricing

Solution : Create Block Line items as per below image. Salesforce is clearly asking for 1-4 but it needs 5 as upper limit. 5-10 but it needs 11 as upper limit.

Error : We can’t find the Product family named Service Packages

While trying completing trailhead challenge Create and Customize Products , I kept getting error We can’t find the Product family named Service Packages. Everything was correct in my org but this error was persistant. Then I temporarily changed org and clicked on challenge button. It failed and then switched to actual org again and this time challenge completed successfully. It seems some kind of caching issue which gets cleared after switching org to check challenge.

Podcast – How to Achieving Hyper-Threading in Salesforce

Podcast - Hyper Thread iN Salesforce

Total number of Asynchronous Apex which includes Batch Apex, Future Method, Queueable & Scheduled job is 250k or 200 x Total User license whichever is greater.

Now lets do some fact check :

  • Execute method of Batch Apex can only call 1 Queueable
  • Scheduler can call 50 Queueable
  • We can have only 100 Schedulers in an Org
  • If we run 1 Scheduler every minute = 60 Scheduler
  • If each Scheduler executes 50 Queueable every minute, then 60×50 = 3000 jobs / min. Which means 3000 x 24 = 72k jobs / day

Big Question

Can you design an application which can use full potential of Async governor limit – even 250k / day ?

Designing Scalable Hyper Thread Application in Salesforce

I have discussed various approach to answer these questions on below podcast by SalesforceWay

Part 1 – Salesforce Hyper-Threading Road blocks

Part 2 – Salesforce Hyper-Threading Options
