YAGNI Principle
Published: 2023-05-01 07:41:39

The You Aren't Gonna Need It (YAGNI) principle is:

> _A software development philosophy that emphasizes the importance of not adding features to a software product until they are actually needed._

This approach is particularly relevant in Agile methodology, where the goal is to maximize the value of the product while maintaining a lean and efficient development process.

## Violation of the principle

A typical violation of the YAGNI principle occurs when developers add features, structures, or components in anticipation of potential future requirements, rather than in response to concrete and current needs.

For example, in the development of an application for managing a store, one might think of creating an advanced reporting system that supports various formats (PDF, Excel, CSV), even though the client has expressly requested only a report in PDF format. This leads to unnecessary complexity and an investment of resources that could be better used for other immediately useful features.

```csharp
public interface IReportGenerator
{
    void GenerateReport(DataSet data, ReportFormat format);
}

public class PdfReportGenerator : IReportGenerator
{
    // Logic for PDF
}

public class ExcelReportGenerator : IReportGenerator
{
    // Logic for Excel
}

public class CsvReportGenerator : IReportGenerator
{
    // Logic for CSV
}
```

## Application of the principle

Applying the YAGNI principle, one would focus solely on the creation of the report in PDF format, as requested by the client. This approach reduces the complexity of the project, focusing development on current needs without worrying about possible future requirements. As a result, the code is leaner, easier to test, and maintain.

```csharp
public class PdfReportGenerator
{
    public void GeneratePdfReport(DataSet data)
    {
        // Specific logic to generate reports in PDF
    }
}
```

## Conclusion

In this article, we explored the YAGNI principle, a fundamental pillar in software development, especially in the Agile field. We saw how its application can prevent overengineering and maintain a focus on real and immediate needs. Following the YAGNI principle allows for the creation of leaner, more flexible software products that are easily adaptable to changes, ensuring efficient use of resources and alignment with business objectives. Ultimately, YAGNI not only simplifies software development but also promotes a more agile and responsive mindset to customer needs.

Understanding the Saga Pattern in Event-Driven Architecture
Tags: eventdriven, tutorial, discuss, architecture
Published: 2023-05-01 07:00:00

## An Introduction
The Saga Pattern differs from the Workflow Pattern because the first involves orchestration, so members of the Saga don't know each other but only know about the output of a previous step. On the other hand, the Workflow Pattern acts as a coordinator. The Workflow Pattern is explained [here](https://dev.to/cadienvan/using-the-workflow-pattern-for-efficient-event-driven-workflows-20ce)

## What is the Saga Pattern?
The Saga Pattern is a design pattern used in Event-Driven Architecture (EDA) to manage long-running transactions that span multiple services or events. A saga is a sequence of local transactions that are orchestrated by a saga participant. Each participant is responsible for executing a transaction and communicating with other participants to ensure system consistency.

## Advantages of using the Saga Pattern
The Saga Pattern offers several advantages in event-driven systems, including improved reliability, scalability, and maintainability. By managing long-running transactions with sagas, the pattern ensures that the system remains consistent even in the face of failures or errors. Additionally, the pattern can be used to implement complex business logic by breaking it down into smaller, more manageable steps. Finally, the pattern makes it easier to maintain the system by encapsulating the transactional logic within the saga participants, making it easier to change or update.

## Implementing the Saga Pattern
To implement the Saga Pattern, sagas must be designed as a sequence of loosely-coupled, autonomous participants that can communicate with each other to coordinate the transactional workflow, but without knowing each other. Each participant is responsible for executing its transaction and communicating with other participants to ensure system consistency. If a participant fails to execute its transaction, it must initiate a compensating transaction to undo the effects of the failed transaction and bring the system back into a consistent state.

## Best practices for using the Saga Pattern
When using the Saga Pattern in Event-Driven Architecture, it is important to follow best practices to ensure the system's reliability, scalability, and performance. Some best practices include designing the sagas to be highly available and fault-tolerant, using idempotent operations to ensure consistency, and monitoring and managing the sagas' performance.

In conclusion, the Saga Pattern is a powerful design pattern used in Event-Driven Architecture to manage long-running transactions and ensure system consistency. By following best practices and designing the system with scalability and fault tolerance in mind, the Saga Pattern can help organizations build reliable and maintainable event-driven systems.

What do you think of the Saga Pattern and how it can help you manage long-running transactions in an event-driven system? Have you used this pattern in your own systems, and if so, what benefits have you observed? Share your thoughts and experiences in the comments below!
Is Less More? How Do You Embrace Simplicity in Coding?
Tags: discuss, beginners, codenewbie, motivation
Published: 2023-05-01 07:00:00

In software development, there is often a drive to add more features and functionality to a project, but sometimes less is more. 

French writer Antoine de Saint-Exupery once said, 

> "Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away." 

How do you balance the desire for new features with the need for simplicity and efficiency? Have you ever encountered a project that became too complex or unwieldy due to feature creep? How did you handle it? Let's discuss the importance of simplicity and minimalism in coding, and share tips for achieving it in our own projects.

React Components - Parent/Child Relationships
Published: 2023-05-01 06:46:13

Components are the building blocks of a React application. You can think of a component as an isolated block of your application that accomplishes a certain task or displays information to the user. In react applications you often have a root entry point into the application in your base .js file. This is where all of the components will be "injected" into the application. Most often you will have a parent component called App.js. This is the root of your component structure that will act as the parent of all of your other components. It's very useful to visualize your component hierarchy like an upside-down tree where App.js is the root and the branches growing down are its child components: 
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/3q2mmp4j07xrf3aknioj.png)

The idea with using React and components is to compartmentalize your application so each component has a specific job or contains specific content. You might have components dedicated to your app's navbar at the top of the page, the footer at the bottom of the page or the main body of your content in the center of the page. You might also have a component dedicated to a user login form or some other kind of form that a user could submit. This might look something like this:
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kexotvxcjw5feq2t9d6r.png)

In this example, Navbar, Footer, Body and LoginForm would all be child components of the parent component, App. Child components can also have children of their own: 
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/rfy4lidbhms6ybe9912s.png)

One of the things I find most interesting about components is how information flows between them and where information lives in a React App. If a component needs certain data, it has to receive it from a parent component and it has to go down the component tree. So if two child components need to share data, they would need to receive that data from a parent. Here is a diagram of how information typically flows in a React app:
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/nd0l4zdn00kikl20n88y.png)


Information flow between components can be a little daunting when you are first learning React. Visualizing components as an upside-down tree and understanding the data flow between them will set you on your way to making fully functional front-end applications.

WeaveDB : Decentralized NoSQL database to consider for your next development project
Tags: weavedb, nosql, database, webdev
Published: 2023-05-01 06:38:34

I have started building my dApp with #[WeaveDB](https://weavedb.dev/) , a decentralized NoSQL database.
Over the past few months, I have been learning about #web3 development, and it's amazing how quickly technology has evolved.
This is just the beginning of many ideas that I plan to build using #WeaveDB
I urge myself to share this dApp with the public so that developers who are interested in learning can replicate, improve upon, and even outperform what I have created with #WeaveDB
While I am no expert, I will try to document every step that I took to create this dApp.
In the meantime, feel free to use the basic features, check the source code, and provide any feedback.
I will continue to improve on this as I progress through my learning journey.
The dApp is an alternative to Eventbrite / Meetup with basic features such as creating an event, RSVPing to an event, creating a user profile, and event owners being able to edit & delete events and view/download(csv) attendees.
You can access the dApp at https://kitakitata.vercel.app
5 Tips to Optimize Your Ruby on Rails App's Performance
Tags: ruby, rails, performance
Published: 2023-05-01 06:25:10

Performance is a critical factor for any application, and Ruby on Rails is no exception. Slow performance can cause user frustration and even lead to **decreased revenue**. Fortunately, there are several ways to optimize the performance of your Ruby on Rails application.

## 1. Use Caching

Caching is a simple and effective way to improve the performance of your application. It stores frequently accessed data in memory, so it can be quickly retrieved when needed. In Ruby on Rails, you can use the built-in caching mechanisms such as Fragment Caching, Action Caching and Page Caching. Fragment Caching allows you to cache only specific parts of a page, while Action Caching caches the entire action response and Page Caching caches the entire HTML page.

## 2. Optimize Database Queries

Database queries are often the biggest bottleneck in a Ruby on Rails application. You can optimize your queries in several ways, including:

- Use `includes` method to eager-load associated objects
- Use `select` to retrieve only the necessary columns
- Use `joins` to join tables and avoid **N+1** queries
- Use `pluck` to retrieve only specific fields of a table

## 3. Use Background Jobs

Background jobs allow long-running tasks to be performed **asynchronously**, freeing up server resources and improving performance. You can use tools like Sidekiq or Resque to handle background jobs in your Ruby on Rails application.

**However, I'd recommend using Sidekiq.**

## 4. Use a Content Delivery Network (CDN)

A Content Delivery Network (CDN) can improve the performance of your application by caching and delivering content from servers located closer to the user. This reduces latency and improves the user experience. There are several CDN providers available, such as Cloudflare, Akamai, and Amazon CloudFront.

## 5. Optimize Asset Management

Assets such as images, CSS, and JavaScript files can significantly impact the performance of your application. You can optimize asset management by compressing and minifying files, using a Content Delivery Network (CDN) to serve static assets, and using a tool like Asset Pipeline to compile and bundle your assets.

**Conclusion**

Optimizing the performance of a Ruby on Rails application requires a combination of techniques and tools. Caching, optimizing database queries, using background jobs, using a Content Delivery Network, and optimizing asset management can all help improve the performance of your application. By implementing these techniques, you can provide a faster and smoother experience for your users, leading to increased engagement and revenue.
Django root base template setup
Published: 2023-04-24 17:29:55

**If you're  learning django you may be familiar with the `{% extends base.html %}` pattern but what if you want all your apps in your project to use the same base template**

Django provides a way of making a parent template to not repeat the  same piece of code in every template _"the DRY pattern (Don't repeat yourself)"_ .
Let's consider you have a Navbar and a Footer, you can make a `base.html` template with them and use it in all your templates.

`your_project/your_app/templates/base.html`

```
<!DOCTYPE html>
<html>
<head>
  <title>Mamamiahh</title>
</head>
<body>

<!-- Navbar start -->
<div>
  <ul>
    <li><a href="default.asp">Home</a></li>
    <li><a href="news.asp">News</a></li>
    <li><a href="contact.asp">Contact</a></li>
    <li><a href="about.asp">About</a></li>
  </ul> 
</div>
<!-- Navbar end -->

{% block content %}
{% endblock %}


<!-- Footer start -->
<div>
 <p> I'm the footer </p>
</div>
<!-- Footer end -->

</body>
</html>
```

You notice the `{% block content %}` and `{% endblock %}` they are placeholders, telling Django to replace this block with content from other sources.

Now you can use your `base.html` with all your template.
let's do it !!

`your_project/your_app/templates/home.html`
```
{% extends "base.html" %}

{% block content %}
  <p>In HTML, spaces and new lines are ignored:</p>

<p>

  My Bonnie lies over the ocean.

  My Bonnie lies over the sea.

  My Bonnie lies over the ocean.
  
  Oh, bring back my Bonnie to me.

</p>
{% endblock %}
```
Now `home.html` can use the base template, this is done by including the base template with the `{% extends %}` tag. 

Good !! but what if you want all your apps template to use the same `base.html`


First create a template folder in your root project and add `base.html`
`your_project/templates/base.html`
Open `settings.py` and find this piece of code
![settings.py screenshot](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xka55mi1kpc34etyi9ff.png)


When  APP_DIRS  is set to  True  , Django automatically finds the  templates/ directory when it's located in an app. However, as we are placing the base template at the project root, you need to specify it in  settings.py  for Django to find this directory.

![Edit settings.py](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/f5c9jdjho7q81ji8phot.png)

Now your `base.html` is ready to use in all your apps, all you need to do is extend it in your templates by using the extends tag `{% extends "base.html" %}` 

Siahhhhhhhh in another blog about django :)
