How Object Calisthenics Helped Me Write Better C# Code

stp2y0 CommentsNewscoding, community, designpatterns, development, engineering, inclusive, software

Hi devs :) I’ve been diving into Object Calisthenics recently, and while it seems like a great practice, I know it’s not everyone’s cup of tea. It’s a set of 9 rules aimed at improving object-oriented design, but some developers are skeptical. Despite that, I’ve found these rules really helpful in making my C# code cleaner and more maintainable. What Are These Rules? Object Calisthenics encourages you to follow nine rules to enhance the modularity and readability of your code. Here’s a rundown with C# examples: One Level of Indentation Per Method Rule: Methods should have only one level of…

DESIGN PATTERNS : A Deep Dive into Common Design Patterns

stp2y0 CommentsNewscoding, community, designpatterns, development, engineering, inclusive, software, softwaredevelopment, softwareengineering, systemdesign

What is a design pattern? Design patterns are solutions to complex problems. Design patterns are all about crafting your classes and interfaces in a way that solves a particular design problem. Usually, while designing a system, we encounter some issues, and for those problems, we have a set of design patterns. Design patterns are generally templates that involve classes, interfaces, and the relationships between those classes. Types of design patterns: Creational design patterns: These types of patterns deal with the creation of objects in a way that is compatible with the given situation.At the creational level, we can determine how…

Minha conclusão ao conhecer os “Design Patterns” [PT-BR]

stp2y0 CommentsNewsbraziliandevs, coding, community, designpatterns, development, engineering, inclusive, programming, software

Introdução Terminei de conhecer os famosos "Design Patterns", descritos originalmente no livro "Design Patterns: Elements of Reusable Object-Oriented Software", lançado em 1994 pelo "Gang of Four" (GoF), que é, de longe, um dos maiores clássicos da área da computação. Organizei com meus colegas um clube do livro para ler uma versão mais acessível, prática e modernizada desse livro, que faz mais sentido para um clube. Trata-se do "Dive Into DESIGN PATTERNS", do famoso site Refactoring.Guru. Minha reflexão Depois de conhecer todos os 22 design patterns, comecei a perceber como eles influenciaram o mundo do desenvolvimento em que vivo hoje. Seja…

The Open/Closed Principle in C# with Filters and Specifications

stp2y0 CommentsNewscoding, community, csharp, designpatterns, development, dotnet, engineering, inclusive, software

Software design principles are fundamental in ensuring our code remains maintainable, scalable, and robust. One of the key principles in the SOLID design principles is the Open/Closed Principle (OCP). This principle states that software entities should be open for extension but closed for modification. Let’s explore how we can adhere to this principle through a practical example involving product filtering. Initial Implementation: The Problem Imagine we have a simple product catalog where each product has a name, color, and size. We need a way to filter these products based on various criteria. A straightforward implementation might look like this: public…

What we will build In this chapter we will implement our own DI Container in JavaScript. We will create a checkout simulation and we are going to use our DI Container to handle the dependency injection. The services Here is the service classes and the flow of our application. We have a credit card, a shipping bag and then a class that handles the transaction and one that sends the order. // Independent service class CreditCard { owner; address; number; cvc; set(owner, address, number, cvc) { this.owner = owner; this.address = address; this.number = number; this.cvc = cvc; } }…

Hello everyone! Today I'll be making a blog on Figma. I wanted to blog on Figma because I see Figma everywhere but I still don't know what it is. Figma helps with the design interface and responsive web design. Figma frames have preset devices and screen sizes. Creating Figma FramesFigma frames can be created by simply hitting on the "A" or "F" key. There is a dropdown pane of the list of devices that the user wants to create the frame with. Frame interactionsThey can be modified by changing preset values or simply dragging the corners of the box. Nesting…

Enhancing Rust Enums in the State Pattern

stp2y0 CommentsNewscoding, community, designpatterns, development, engineering, inclusive, learning, rust, software

In my previous article, I discussed how Rust enums should be strongly considered when the solution benefits from a state machine. The strongest argument for this is the fact that the Rust compiler will inform you when a state variant isn't covered in a match expression. This was stemmed from a state pattern example provided by the official Rust book. The sample scenario they used was an article that was required to go through the status of Draft, PendingReview, and Approved. Using a similar strategy as I explained in my original article, I came up with the following code: post.rs…
