The Serious Stack Behind Salesforce Developers — Part 2

See the original posting on DZone Python

What Is a Salesforce Application Developer?

In my prior post, I raised the question of why traditional developers should consider Salesforce Developer as a career. I also reviewed some aspects of how Salesforce has evolved over the years into a deeply technical developer platform that requires a community of serious developers.

In this post, I’ll focus on what it means to be a Salesforce Business App Developer and look at the capabilities of the platform that require sophisticated development skills to achieve success  with an architecture that is both declarative and programmatic.  

Create CRUD endpoints using Hyperlambda

See the original posting on DZone Python

Hyper implies web, and lambda implies function – Hence, Hyperlambda translates into "web functions", and this is a fairly accurate description. However, hyper also implies "super fast", and by super fast here, I mean super fast! 1 minute and 45 seconds was what I needed to create CRUD endpoints wrapping my database table, manually creating my endpoints in the following video, while explaining how I did it simultaneously.

According to modern studies in the subject, the number of lines of code your project consists of, is directly proportional to the amount of energy and resources you’ll need to spend maintaining it. Hence, the fewer lines of code, the fewer resources are required to maintain it. In the video above, I copy and paste 50 lines of code, and I end up with 4 HTTP REST CRUD endpoints. Comparing this to C# is arguably unfair. Simply the boiler plate code for my Controller, would probably end up exceeding this number. You can find my code for all endpoints below.

Creating a Cross-Platform Todo Aggregator with Flutter

See the original posting on DZone Python

Flutter is a UI toolkit from Google (but open source with a strong community) for creating natively compiled applications for mobile, web, and desktop. This places Flutter alongside other cross-platform toolkits and frameworks such as React Native and Xamarin as well as specific native options such as C#, Java/Kotlin, and Objective-C/Swift. Thanks to the increase in the adoption of JavaScript everywhere, the market for cross-platform development toolkits and frameworks has narrowed, but why should any developer consider Flutter for their cross-platform needs. In this article, I look at how to get started with Flutter, and it’s positives, negatives, and pitfalls.

I always find it useful to have an itch you’re trying to scratch when learning a new tool, so I took this opportunity to solve one of mine that Flutter seemed well suited too. As a long-term freelancer, generally working across multiple projects at one time, I use multiple sources of to-dos. For a while, I’ve used a great Chrome extension called Taco that aggregates from a lot of sources, but not all of the ones I use, and I wanted more from it. I’m old fashioned and also like applications and apps as opposed to websites, and would ideally like something that can work offline as much as possible. As far as I could tell, Flutter could fulfill all these needs, and it’s one main negative that I’d still need some form of backend service too, something I only really realized about 3/4 through working on this article. I won’t cover creating an entire application if this scope in this article, but cover creating the basics, and maybe cover later steps in future articles, or you can keep an eye on the project GitHub repo.

MEAN vs LAMP For Your Next Project of Programming

See the original posting on DZone Python

Choosing the best technology stack has always been tricky for investors. With 82% of issues occurring in the code of the programs, it is imperative to find & use the best one for your next programming project.

MEAN v/s LAMP which one’s the best? Well, the answer cannot get summarized in a single line, but the best thing to say is: It is directly dependent on a series of features of your project.

Discovering Rollbar as a Spring Boot Developer

Just because we do something one way, doesn’t always mean it is the right way … or even the best way.

As long as I can remember, I’ve included log messages in my code to provide run-time insight into what the code is really doing. From developers running locally all the way to the eyes of a production support engineer, these extra lines of code are meant to help troubleshoot unexpected scenarios.

How to Build a Pokedex React App with a Slash GraphQL Backend

See the original posting on DZone Python

Frontend developers want interactions with the backends of their web applications to be as painless as possible. Requesting data from the database or making updates to records stored in the database should be simple so that frontend developer can focus on what they do best: creating beautiful and intuitive user interfaces.

GraphQL makes working with databases easy. Rather than relying on backend developers to create specific API endpoints that return pre-selected data fields when querying the database, frontend developers can make simple requests to the backend and retrieve the exact data that they need—no more, no less. This level of flexibility is one reason why GraphQL is so appealing.

Implementing the Repository Pattern Using C# and Entity Developer in ASP.NET Core

See the original posting on DZone Python


The Repository Pattern is one of the most popular design patterns used for abstracting how data is eventually persisted in the database or retrieved from the database. The basic objective of the Repository Pattern is to help you decouple the data access and business logic layers of an application. This article talks about how we can implement the repository pattern in C# and take advantage of Entity Developer to talk to the database.

Why Should We Use an ORM?

An ORM is an acronym for Object Relational Mapper – it is used to map your domain objects to the objects in the relational model. In other words, it is used to map data between incompatible type systems. Entity Developer from Devart is an ORM designer tool that lets you design your data access layer visually. It sits on top of ADO.NET and simplifies the way you work with data.

Web Component Solutions: A Comparison

See the original posting on DZone Python

“Don’t repeat yourself.” Every programmer has this concept drilled into their head when first learning to code. Any time you have code you find yourself duplicating in several places, it’s time to abstract that code away into a class or a function. But how does this apply to user interfaces? How do you avoid re-writing the same HTML and CSS over and over again?

If you’re using a UI framework like Angular or a UI library like React, the answer is simple: you build a component. Components are bits of HTML, CSS, and JavaScript put together in a way that they can be easily reused.

Top Entity Framework Core Tools and Extensions

See the original posting on DZone Python


Entity Framework is an Object Relational Mapper (ORM) tool from Microsoft that has been an extremely popular ORM tool from the time it was available. It enables developers to create data-centric applications by programming against a conceptual model rather than the relational model thereby solving the impedance mismatch between the way data is represented in the application and how it is actually stored in the database.  

This article discusses the top Entity Framework and Entity Framework Core tools and extensions. The tools and extensions discussed in this article include the following: –

Integrating Twilio Into My SaaS Solution In Heroku

See the original posting on DZone Python

In the "Using Heroku to Quickly Build a Multi-Tenant SaaS Product" article, I documented the foundation for a new SaaS solution that I am building (initially for my sister-in-law) — utilizing the Heroku ecosystem. At the end of that article, I had planned to write about the core technologies (Spring Boot, Angular 9, ClearDB, Okta, GitLab and Heroku) in place, as we raced for the 1.0.0 release of the solution.

However, things have been moving fast around here, and I largely attribute the speed of development and end-user adoption to everything that Heroku brings to the table for this service. As I have noted before, using Heroku as the destination for my service and GitLab’s built-in CI/CD pipelines — updates that are merged from a feature branch into the master branch of the client or service are automatically deployed into production (Heroku) without any further intervention.

How To Develop And Deploy Micro-Frontends Using Single-Spa Framework

See the original posting on DZone Python

Micro-frontends are the future of frontend web development. Inspired by microservices, which allow you to break up your backend into smaller pieces, micro-frontends allow you to build, test, and deploy pieces of your frontend app independently of each other. Depending on the micro-frontend framework you choose, you can even have multiple micro-frontend apps — written in React, Angular, Vue, or anything else — coexisting peacefully together in the same larger app!

In this article, we’re going to develop an app composed of micro-frontends using single-spa and deploy it to Heroku. We’ll set up continuous integration using Travis CI. Each CI pipeline will bundle the JavaScript for a micro-frontend app and then upload the resulting build artifacts to AWS S3. Finally, we’ll make an update to one of the micro-frontend apps and see how it can be deployed to production independently of the other micro-frontend apps.

Automating NuxtJS Deployment to Heroku with CircleCI

See the original posting on DZone Python

Manually deploying a NuxtJS project is pretty easy when teams are small. However, as projects and teams grow they usually turn to CI/CD in their DevOps to automate their testing and deployment. This is when deployments—and the setup of deployments—can get complicated.

In this article, we’ll look at how to easily set up an automated CI/CD system for a NuxtJS project using Heroku and CircleCI. We’ll walk through all the details from setting up your GitHub repository to automating your tests to pushing your code changes. Then we’ll look at some suggested next steps.
