We are going to create LWC Component to acts as a utility method to read query parameter , as shown below

Avoid asking your users to upload pictures – Use Globally Recognized Avatar , 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

Email address to render avatar
Size of avatar
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

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.

When to use which integration patterns in Salesforce along with best practices. Video to show how to use Outbound message to integrate Salesforce without writing code

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

Solutions to Trailhead Challenges

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.

Pricing Methods for Salesforce CPQ – Implement Block Pricing

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

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.

Podcast – How to Achieving Hyper-Threading in Salesforce

posted by Jitendra on January 2, 2020March 14, 2020 under category Salesforce and tagged as podcast, Technical Architecture, Thread with 2 Comments

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

Federated Search in Salesforce

posted by Jitendra on January 2, 2020January 2, 2020 under category Salesforce and tagged as External Object, Federated Search, Integration, Open Search Document with Leave a comment

Search content of Jitendra Zaa’s blog using federated search in Salesforce

Using Federated Search, we can search for content outside Salesforce. Federated Search utilizes Open Search Document behind the scene. Open Search was coined by Jeff Bezos (CEO – Amazon) in March 2005. Open Search is a collection of technologies & standards that allows publishing of results to be utilized by Search Engines.

For Demo purpose, I have enabled my website compatible with Open Search at below URL

https://www.jitendrazaa.com/blog/wp-json/opensearch/1.1/document

Step 1 :

Add External Data Source by clicking New External Data Source.

Provide any suitable name – in this case Jitendra’s Blog.

Select Federated Search : OpenSearch as Type.

Provide this path for OSD (Open Search Document) file format – https://www.jitendrazaa.com/blog/wp-json/opensearch/1.1/document

Click on Validate and Sync.

Step 2 :

Create permission set giving permission to view this External Object and all fields. Assign this permission set to anyone who needs to use search for content outside Salesforce.

We can also enable this federated search in Communities by updating global Search Component and giving community members access to this newly created permission set.

Once above setup is completed – you can search for any term on global search and select External Results as shown in below image :
