Why DTOs are a Must-Have in Nest.js API Development
Tags: webdev, javascript, beginners, productivity
Published: 2023-01-28 11:17:51

**DTO**, or **Data Transfer Objects**, are a crucial concept in building robust and maintainable APIs, especially when using Nest.js. They serve as a way to structure and validate the data that flows between the client and the server.

One of the main advantages of using DTOs in Nest.js is that they allow for a clear separation of concerns between the client and the server. By defining a specific set of data that the client can send to the server, and a specific set of data that the server will send back, we can ensure that the API is only handling the data that it needs to. This can help to reduce the complexity of the API and make it easier to maintain.

Here is an example of how to define a DTO in Nest.js:

```

import { IsString, IsInt } from 'class-validator';

export class CreateProductDto {
  @IsString()
  readonly name: string;

  @IsInt()
  readonly price: number;
}

```
DTOs also provide a way to validate the data that is being sent to the API. By defining a set of rules and constraints for each DTO, we can ensure that the data that is sent to the API is in the correct format and contains all of the necessary information. This can help to prevent errors and bugs in the API, and make it more reliable and robust.

For example, in this CreateProductDto, we are using the class-validator package to ensure that the name property is a string and the price property is an integer.

Another important aspect of DTOs is that they can be used to transform the data that is sent to the API. For example, we can use DTOs to convert data from one format to another, or to add or remove fields from the data. This allows us to have more control over the data that is being sent to the API, and can help to make the API more flexible and adaptable.

In summary, DTOs are a powerful tool for building robust and maintainable APIs in Nest.js. They allow for a clear separation of concerns between the client and the server, and provide a way to validate and transform the data that is sent to the API. By using DTOs in your Nest.js API, you can ensure that your API is reliable, flexible and easy to maintain.

Understanding black-box and white-box testing
Tags: testing, programming, beginners, webdev
Published: 2023-01-28 10:57:10

## What is black-box testing?
Black-box testing is a method of software testing that examines the functionality of an application without peering into its internal structures or workings. It is also known as functional testing or behavioral testing. The tester is only concerned with what the application does, not how it does it. The goal of black-box testing is to ensure that the application meets its requirements and behaves as expected for the end user.

## Should we test internal parts with functional test cases?
Functional testing, also known as black-box testing, is focused on testing the software application's external behavior and functionality, as seen from the end user's perspective. It is not typically used to test the internal workings or structure of the application.

Internal parts of an application, such as individual modules or components, are typically tested using unit testing, which is a method of testing individual pieces of code in isolation. Developers typically write unit tests to verify that the code they have written is working correctly and meets the requirements.

That being said, it is possible to have functional test cases that test the internal parts of the application by testing the interaction of different internal components, in this case, it's called integration testing. This method of testing ensures that the various parts of the application are working together correctly and that there are no conflicts or issues when they are integrated.

In summary, functional testing is focused on the external behavior and functionality of the application, while unit testing and integration testing are focused on the internal parts of the application.

## What are the key differences between black-box and white-box testing?
Black-box testers only have access to the inputs and outputs of the application, and not to the internal code. This method of testing is used to ensure that the application behaves as expected for the end user and meets its requirements.

On the other hand, white-box testers have access to the internal code and design of the application and use this information to test individual pieces of code to ensure that they are working correctly. This method of testing is used to ensure that the application is functioning correctly at the code level and to identify any bugs or issues that may not be visible from the user's perspective.

## In summary, the key differences:
- Black-box testing is done from the user's perspective, while white-box testing (unit, integration, etc.) is done from the developer's perspective.
- Black-box testing does not require access to the internal code, while white-box testing requires access to the internal code.
- Black-box testing is focused on testing the external functionality and behavior of the application, while white-box testing is focused on testing the internal code and design.

Reactivity without Virtual DOM on the example of cample.js beta versions
Tags: webdev, javascript, reactivity, cample
Published: 2023-01-28 10:52:16

Hello! In this short article, I would like to share my thoughts on reactivity without a virtual DOM.

I think that this is a very promising technology that will allow you to redraw the UI as quickly as possible without comparing node elements. At its core, the virtual DOM involves a comparison process, which helps JS understand when to update a node and when not.

This is a good technology and in the first beta versions of cample.js it was specifically implemented, but during development I came to understand that the virtual DOM has a <u>_collective effect_</u> that slows down the redrawing work, because you need to store large objects that describe the DOM or the nodes themselves.

```

if(isDeepEqualNode(this._dynamic.oldNode, e)){
 ...redraw
}
```
sample code version 2.0.0-beta.2

I may not have much experience, but I think it is in my opinion, this is so.

I think it's possible to compress an element's node object as much as possible so that the Virtual DOM runs faster, but still leaves the basis of object comparison. And this basis has a speed limit.

But, nevertheless, the virtual DOM is very convenient, especially when working with string interpolation. This will keep track of the newly added interpolation in the DOM, which will allow the UI to be redrawn, thus making development easier.

```
<div>{{dynamicData}}</div>
```
string interpolation example

Also, there is a big problem and opportunity in reactivity without virtual DOM, because in essence, the render happens once.

```
class Component{

render(){
 render();
 ...do a render once and work with the first nodes
}

}

```
sample code version 2.0.0-beta.3

Thus, that possibility of reRender with string interpolation disappears, which is not cool.

Therefore, there is a big plus in working with the Virtual DOM, and given that the Virtual DOM can still be really, if not faster, then almost equal in speed, then there is already a selection process when developing a framework.

Yes, you can try to add new elements to the nodes array of the first render, but then it becomes necessary to monitor changes in the DOM, which, again, mainly leads to the creation of the Virtual DOM.

And this, I think, is a big minus of the technology of redrawing without the Virtual DOM.

Summing up, I think that each technology has its pros and cons. Yes, processing without Virtual DOM is faster, but it has its drawbacks, which I described above. Here a big role is played by the project under which the work with this or that tool is going on.

P.S. Thank you all for reading! Perhaps I do not know much, but I think that these thoughts may have a place to be. And what do you think?
How to send SMS Notifications in Laravel using Twilio
Published: 2023-01-28 10:42:29

Hello Artisans,

In this blog post we will see how we can send sms notifications using laravel.

In Laravel,  we can send SMS notifications using a package such as Twilio or Nexmo. In this post we are going to see how we can send SMS using Twilio package.

So let's get started by installing Twilio package:
```php`
composer require twilio/sdk
```

Create a new notification class using the php artisan `make:notification command`.

```php
php artisan make:notification SendSMS
```

In the newly created notification class, add a toTwilio method. This method will contain the logic for sending the SMS using the Twilio package.

```php
use Twilio\Rest\Client;

public function toTwilio($notifiable)
{
    $twilio = new Client(env('TWILIO_SID'), env('TWILIO_TOKEN'));

    $message = $twilio->messages
                    ->create("+1234567890", // to
                        array(
                            "body" => "Hello from Laravel!",
                            "from" => "+0987654321"
                        )
                    );
    return $message;
}
```

In the above code you need to replace TWILIO_SID and TWILIO_TOKEN with your Twilio account SID and token respectively. Also replace the "to" and "from" numbers with the phone numbers you want to send the message to and from.

To send the notification, you can use the Notification facade's send method and pass it the notifiable instance and the notification class.

```php
Notification::send($user, new SendSMS());
```

Now you can send SMS notification to the user.

Note: You also need to config your Twilio account with phone numbers and other settings.


Thank You!!
Happy Reading :unicorn: :heart:

Optimizing Process and Thread Management: Unleashing the Power of Concurrent Computing
Tags: programming, computerscience
Published: 2023-01-28 10:00:00

In today's fast-paced world, the ability to perform multiple tasks simultaneously is more important than ever. Process and thread management is the key to concurrent computing, allowing multiple tasks to be executed at the same time, making the best use of available resources. In this article, we'll explore why process and thread management is important, how it affects other areas of computer science, and what it is.

---

First, let's talk about why process and thread management is important. In a computer system, a process is a program that is running and can be thought of as a separate instance of a program. A thread is a lightweight process that runs within a program, allowing multiple tasks to be executed simultaneously. This allows a program to perform multiple tasks at the same time, making the best use of available resources. Process and thread management is essential for achieving optimal performance in concurrent computing.

Process and thread management also plays a crucial role in the reliability and security of a system. By isolating processes and threads from one another, the operating system can prevent a malfunctioning or malicious process from affecting the stability of the entire system.

In addition to its importance for individual programs, process and thread management also affects other areas of computer science. For example, it is a key aspect of operating system design, as the operating system is responsible for managing the processes and threads running on the system. It also plays a crucial role in distributed systems, where multiple machines work together to perform a task.

So, what is process and thread management? Process management is the process of managing the execution of processes, while thread management is the process of managing the execution of threads. It includes creating, scheduling, and terminating processes and threads, as well as managing their execution and communication. This is typically handled by the operating system, but programming languages and libraries also provide APIs to create and manage threads.

---

In conclusion, process and thread management is the key to concurrent computing, allowing multiple tasks to be executed simultaneously, making the best use of available resources. It is essential for achieving optimal performance, reliability, and security in a computer system. By understanding process and thread management, and how to use it effectively, we can unleash the power of concurrent computing and optimize the performance of our systems. So, let's master the art of process and thread management and unleash the power of concurrent computing.
The 4 Steps to Free Up Your Schedule, and Focus on What You Want to Do, From “The 4-Hour Work Week”.
Tags: startup, career, productivity, writing
Published: 2023-01-28 09:59:05

Is your calendar full, and do you want to free up more time?

"The 4-Hour Work Week," by Timothy Ferriss, offers methods for identifying tasks that can be automated or outsourced. By outsourcing or automating tasks that are not crucial to the operation of your company or that are simple for someone else to complete, you can free up time for more important efforts.

## Step 1: You need to track your tasks first to optimize them.

You must keep track of your routine tasks to analyze them.

Keeping a task log is one of the key methods Ferriss recommends for identifying tasks that can be automated or outsourced. You can figure out which tasks take up the most time and which can be automated or outsourced by keeping a log of everything you do daily, weekly, or monthly. This is helpful for getting a clear picture of your time management and tracking down the tasks that would be best handled by automation or outsourcing.

You can learn so much from your activities if you track them accurately.

## Step 2: Automate or outsource non-core tasks first.

With a complete picture of all your tasks, you can start choosing which ones are good candidates for outsourcing or automation.

To begin with, list non-core tasks. These activities are not crucial to your company's core operations. You can focus on outsourcing or automating these tasks first after identifying them. The time-consuming non-core tasks should receive the majority of attention. You'll be able to accomplish more in less time while also having more freedom and flexibility.

Don't outsource your core tasks because they are the ones that add the most value to your business.

## Step 3: Automate or outsource repetitive tasks to save time and money.

We spend a large portion of our day performing the same routine tasks every day.

Routine tasks make excellent candidates for automation or outsourcing. Software can easily automate them, or you can hire a virtual assistant to do the work for you. This can save time and effort and free up your time.

Pushing away these repetitive tasks will also help you focus better, as you can concentrate on the important daily decisions you make.

## Step 4: Examine the benefits and costs of outsourcing.

Finally, weighing the advantages and disadvantages of outsourcing or automating a task is critical.

This entails considering how much time and money you will ultimately save. By sticking to this principle, you can decide which tasks are best kept in-house and which should be outsourced or automated. For instance, it isn't worth automating a task that takes five minutes every month if it takes two months to automate it.

At the end of the day, you should view it through a business lens and ensure that these actions ultimately benefit your company.
