Enhancing NestJS Development: Improving Module Management Efficiency
Tags: nestjs, modul, cleancode, typescript
Published: 2024-05-15 14:28:06

NestJS is a powerful framework for building web applications, offering a structured way to organize your code through modules. This guide will walk you through setting up your modules effectively, making your development process smoother and your codebase more manageable. 

### Understanding Modules in NestJS
Modules in NestJS act like containers for different parts of your application, such as user management or product listings. They help in separating concerns, making your code easier to understand and maintain.  

**Before: Basic Module Structure**
Before adopting a structured approach, your module might look something like this:
```
/src
  /user
    auth.controller.ts
    user.entity.ts
    auth.service.ts
    user.module.ts
```
This structure mixes different types of files, making it harder to navigate and maintain as your application grows.

**After: Structured Module Approach**
By organizing your module with dedicated directories for each type of file, you create a clearer and more scalable structure:
```
/src
  /user
    /controllers
      auth.controller.ts
      profile.controller.ts
    /services
      auth.service.ts
      profile.service.ts
    /entities
      user.entity.ts
    /repositories
      user.repository.ts
    /guards
      auth.guard.ts
    user.module.ts
```

### Organizing Your Module
To keep your module clean and easy to navigate, follow these steps:

- Separate Concerns: Place each type of file (services, controllers, entities, etc.) in its own directory within the module.
- Keep the Module File Simple: The user.module.ts should mainly import and configure other components, keeping the module's entry point clear and concise.

**Expanding Your Module**
As your application grows, you might want to add more features to your module. For example, adding a profile feature would involve:

1. Creating a Profile Controller: Handle requests related to user profiles.
    - File path: src/user/controllers/profile.controller.ts
2. Adding a Profile Service: Manage the logic for fetching and updating user profiles.
    - File path: src/user/services/profile.service.ts
3. Updating the Module: Ensure your user.module.ts imports and provides the new controller and service.

**Benefits of Good Module Management**

- Easier Navigation: Knowing exactly where to find each part of your module speeds up development.
- Better Scalability: Adding new features becomes straightforward when you have a clear structure.
- Improved Collaboration: Other developers can quickly get up to speed with your project.

**Final Thoughts**
By organizing your NestJS modules with dedicated directories for controllers, services, entities, and other components, you create a solid foundation for your application. This approach not only makes your codebase more readable and maintainable but also prepares it for future growth and collaboration.
Build a Simple JSON API with Express.js on a Local Server
Tags: express, javascript, beginners, webdev
Published: 2024-05-15 14:25:30

Creating a simple server looks like an exciting thing to do. If you're fetching data from other sites, why not create your own server for accessing API data?

It's Easy!!

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/vc7shi96xh1g54gky3e7.jpg)

Let's learn how to make a local server using express.js for your project by following these steps:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/zbp75demeuksn6v2abmu.jpg)

First, you need to install Node.js. I assume that you have already installed Node.js on your computer.

## Install and setup the server:

First, create the backend server:  
```
mkdir my-app-server
```

Go to the folder path:  
```
cd my-app-server
```

npm init: 
```
npm init -y
```

npm install express:  
```
npm install express
```

Install cors: 
```
npm install cors
```

Cors gives access to the server for your project (API call). Otherwise API call in your project will show 'failed to load'. 

Then create a file 'index.js'. Now write code in 'index.js'. 

```js
const express = require('express');
const app = express();
const cors = require('cors');
const port = process.env.PORT || 5000;

const categories = require('./data/categories.json');

app.use(cors());

app.get('/', (req, res) => {
    res.send("Server is running");
});

app.get('/categories', (req, res) => {
    res.send(categories); 
})

app.listen(port, () => {
    console.log(`Server (categories) is running on port: ${port}`);
})

```

Our data file is `categories.json`. 

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/slnppocgmhfwsbdp1m31.png)

### Data of `categories.json` file: 

```json
[
    {
        "id": 1,
        "category": "World",
        "total_news": 150
    },
    {
        "id": 2,
        "category": "Politics",
        "total_news": 120
    },
    {
        "id": 3,
        "category": "Business",
        "total_news": 100
    },
    {
        "id": 4,
        "category": "Technology",
        "total_news": 80
    },
    {
        "id": 5,
        "category": "Sports",
        "total_news": 90
    }
]
```

## Run the server:

Run the server using nodemon: 
```
nodemon index.js
```

Nodemon helps to update the server in real-time. 

Open your web browser and go to `http://localhost:5000`. You should see "Server is running" displayed on the page. 


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/1mexvb9rj58z3lleraxs.png)


If you go to `http://localhost:5000/categories`. Then you can see some categories of data. 

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ck3ha9z6n0csaxjfqlx4.png)

Now you can easily access this data for your project.

DEV não coloque a mão na massa até ter certeza do que você deve implementar
Tags: beginners, braziliandevs
Published: 2024-05-15 14:05:29

Olá, Mentes Tech!

Se você disser sim, para qualquer das perguntas abaixo, este texto é para você.

Tenho retrabalho ?

A minha entrega não cumpre com o esperado pelo cliente ?

Não consigo entender o que o meu cliente quer ?


Na carreira de um Engenheiro de Software, isto é mais comum do que parece.

E pode acontecer quando o cliente está indeciso, quando não há clareza dos objetivos, quando não está relacionado a alguma métrica ou algum número que você gostaria que aumentasse ou diminuísse, uma ui que não está amigável.

Note que as situações o problema não está na sua implementação, mas na forma como você entendeu o desafio. concorda que aqui temos uma possibilidade do ponto de falha ser o planejamento, em vários níveis ?

Mas o meu foco é no desenvolvimento de software, imagine que você possui uma especificação do que o cliente quer.

Alinhe expectativas, faça protótipos, mapeie os pontos de solução em alto nível, um ponto de solução pode ser granular e pode chegar a nível de registradores, dependendo da entrega.

Antes de colocar a mão na massa. 
Após alguns anos fazendo o planejamento antes da implementação, ir para IDE é somente para digitar, pois a solução já está validada planejada e vai fazer exatamente o que foi proposta para fazer no planejamento, note que todo esforço está concentrado no planejamento e não na execução.

Codificar virou apenas uma tarefa de digitação, ou delegar para o Copilot.

Como você planeja suas entregas ?

There is now a blank public repo for the "fully-featured, infinitely scalable IaaS with predictable pricing." It's pretty minimal, but it's good to slow down and think about how things are laid out. The further I get into this project, the more I question whether a fork-able repository or a CLI that generates boilerplate is the right approach. Either way, it will be valuable to prove that all of these dependencies work together.

Repository: https://github.com/winstonpuckett/sunflower

![Current repository structure](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ru4yqh5fwqshqb6x01kd.png)

I've also narrowed what the experience should feel like. A user who has never heard of Sunflower should be able to complete "hello, world" within 5 minutes. This might be hard given the prerequisites (like, "have a Kubernetes cluster already").

Java Stream flatMap() Example :)
Tags: adj, adj1688
Published: 2024-05-15 13:30:14


java
The Java Stream flatMap() method is an intermediate operation.

The Stream.flatMap() function, as the name suggests, is the combination of a map and a flat operation. This means you first apply the map function and then flatten the result.

Java Stream flatMap() Example
To understand what flattening a stream consists in, consider a structure like [ [1,2,3],[4,5,6],[7,8,9] ] which has "two levels". It's basically a big List containing three more List. Flattening this means transforming it in a "one level" structure e.g. [ 1,2,3,4,5,6,7,8,9 ] i.e. just one list.

For example: In the below program, you can see that we have three lists that are merged into one by using a flatMap() function:
import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;
import java.util.stream.Stream;

public class Main {
    public static void main(String[] args)
    {
        List<Integer> evens = Arrays.asList(2, 4, 6);
        List<Integer> odds = Arrays.asList(3, 5, 7);
        List<Integer> primes = Arrays.asList(2, 3, 5, 7, 11);
        List<Integer> numbers = Stream.of(evens, odds, primes)
                .flatMap(list -> list.stream())
                .collect(Collectors.toList());
        System.out.println("flattend list: " + numbers);
    }
}
Output:
flattend list: [2, 4, 6, 3, 5, 7, 2, 3, 5, 7, 11]
Internet, from content to a place
Tags: placeholder
Published: 2024-05-15 13:20:53

_This is an unfiltered placeholder for a concept I have been thinking about._

In the 90s, the web was mainly about content. It was like a virtual business card, newspaper, or gossip magazine. We had chats, forums, and messaging platforms, adding social interactions. It evolved from a few people talking on forums to almost everyone chatting online. Content creation and consumption exploded.

With mobile technology, the internet became a hub for interaction. During the pandemic, it turned into a place for work, services, and collaboration. The internet is now more about experiences and interactions than just content.

We can provide professional services through the web, like live or recorded videos, and platforms mimicking physical services. AI tools can create logos (Looka) or mockups (PlaceIt). Calendly manages schedules, and ChatGPT interacts with teams.

These are waves of technology adoption overlapped. So there are some companies that are still looking for their virtual business cards, while others are already living in the web.

Designers live in Figma, using it as their toolbox and community. For developers, we have GitHub and npm for content, and Discord and Dev.to for social interactions. But these are scattered.

We are creating a unified place for developers to live, work, and collaborate with teams, clients, and the community. This is our vision for Webcrumbs.
Discover the Power of GPT-4o: New Features and Emotion Recognition

OpenAI launched a new version of ChatGPT named GPT-4o on May 13th, 2024, and it's generating a lot of excitement for its potential to revolutionize human-computer interaction. Let’s take a look at its new possibilities, features and how GPT-4o can recognize emotions.

## About GPT-4o
GPT-4o (“o” for “omni”) is a new AI model designed for smoother interaction between humans and computers. It can take in information through text, audio, images, and even videos, and respond in the same formats. Interestingly, its response speed is on par with humans, taking around 232 to 320 milliseconds on average.

While similar to previous models in its ability to handle English text and code, GPT-4o excels in understanding non-English languages and is significantly faster and cheaper to run. It also boasts a major advantage in processing visual and audio data compared to existing AI models.

In simpler terms, GPT-4o is like a supercharged AI assistant that can understand and respond to you in a more natural way, using different communication styles and languages.

Elevating User Experience: Harnessing CSS Animations
Published: 2024-05-15 13:00:00

In the ever-evolving landscape of web development, user experience (UX) remains paramount. As websites strive to engage and retain visitors, the integration of captivating design elements becomes increasingly vital. Among these, CSS animations stand out as a powerful tool for enhancing UX, providing a dynamic and visually appealing interface. In this article, we'll explore the art of leveraging CSS animations to elevate user experience, accompanied by practical coding examples.

Understanding CSS Animations:
CSS animations enable developers to animate HTML elements without the need for JavaScript or Flash. By simply defining keyframes and specifying animation properties, such as duration and timing function, intricate animations can be achieved with relative ease.

Enhancing User Engagement:
1. Loading Animations:
Loading animations are indispensable for keeping users engaged during content loading. With CSS animations, loading spinners or progress bars can be seamlessly integrated, providing visual feedback to users while content loads in the background.

```
@keyframes spin {
  0% { transform: rotate(0deg); }
  100% { transform: rotate(360deg); }
}

.spinner {
  width: 40px;
  height: 40px;
  border: 4px solid rgba(0, 0, 0, 0.1);
  border-left-color: #7983ff;
  border-radius: 50%;
  animation: spin 1s linear infinite;
}

```
2. Hover Effects:
Hover effects add an interactive dimension to websites, enticing users to explore further. CSS animations can be utilized to create smooth transitions and transformations when users hover over elements.

```
.button {
  background-color: #7983ff;
  color: #fff;
  padding: 10px 20px;
  border-radius: 5px;
  transition: background-color 0.3s ease;
}

.button:hover {
  background-color: #5d68d6;
  transform: scale(1.1);
}

```
3. Scroll Animations:
Scroll animations are effective in guiding users through content, adding a layer of interactivity and visual appeal. By triggering animations based on scroll events, websites can deliver a more immersive browsing experience.

```
@keyframes fadeInUp {
  0% { opacity: 0; transform: translateY(20px); }
  100% { opacity: 1; transform: translateY(0); }
}

.animate-up {
  opacity: 0;
  animation: fadeInUp 1s ease forwards;
}

```
Conclusion:
Incorporating CSS animations into web design not only enhances the visual appeal but also contributes significantly to user engagement and retention. By mastering the art of CSS animations, developers can create immersive and memorable experiences that leave a lasting impression on users.

Are you ready to elevate your web design skills with CSS animations? Embrace creativity, experiment with different effects, and unlock the full potential of user experience enhancement. Happy coding!
