Error Handling In Javascript
Tags: javascript, erro, webdev, programming
Published: 2023-02-28 07:04:44

There are several ways to handle errors in JavaScript. Here are some common methods:

## 1. try...catch:
This is the most common way to handle errors in JavaScript. With this method, you wrap your code in a try block and catch any errors that may occur in a catch block.

```
try {
  // some code that might throw an error
} catch (error) {
  // handle the error
}
```

## 2. throw:
You can use the throw keyword to manually throw an error in your code.
Example:

```
function divideByZero(num) {
  if (num === 0) {
    throw new Error('Cannot divide by zero');
  } else {
    return 10 / num;
  }
}

try {
  divideByZero(0);
} catch (error) {
  console.log(error.message);
}
```

## 3. finally:
The finally block is executed regardless of whether an exception was thrown or caught. This block is often used to clean up resources or perform some action that needs to happen regardless of the outcome of the try...catch block.
Example:

```
try {
  // some code that might throw an error
} catch (error) {
  // handle the error
} finally {
  // do something whether an error was thrown or not
}
```
## 4. Promise.catch():
If you're using Promises in your code, you can handle errors with the catch() method. This method catches any errors that occur in the Promise chain.
Example:

```
myPromise.then(result => {
  // do something with the result
}).catch(error => {
  // handle the error
});
```
## 5. window.onerror:
This method is used to catch unhandled errors in your code. It can be helpful in debugging your code and finding errors that may have slipped through your other error handling methods.
Example:

```
window.onerror = function(message, url, line, column, error) {
  console.log('Error: ' + message + '\nURL: ' + url + '\nLine: ' + line + '\nColumn: ' + column + '\nStack trace: ' + error.stack);
}
```
## 6. Error: 
This method creates a new Error object with a specified message.
Example:

```
const err = new Error('Something went wrong.');
console.log(err.message);
```
## 7. console.error():
This method logs an error message to the console.
Example:

```
console.error('Something went wrong.');
```

> Note that error handling is a crucial part of writing robust and reliable code. You should always make sure to handle errors properly in your code.

So, these are some of the most common ways to handle errors in JavaScript.
How can multiple programs be executed?
Published: 2023-02-27 21:00:32

# **How can multiple programs be executed?**

- Program: A collection of commands that a computer can execute.
- Process: A program that is running on a computer. Each process is assigned an independent memory space.
- CPU: The computational unit that executes commands.
- Main Memory:  Where processes wait to be executed by the CPU.
- I/O(Input/Output): Reading and writing files, sending and receiving data somewhere on the network. Handling input and output devices and sending or receiving data.

## Single process system
Only one program runs at a time. CPU usage is not efficient because when a program performs an IO operation, the CPU is idle.
&rarr; Load multiple programs into memory and execute them simultaneously. When IO operation occurs, another process runs on the CPU:

## Multiprogramming
To maximize CPU usage.

**Disadvantages**
If the CPU usage time is long, the processes continue to wait.
&rarr; Let the process run for a very short time(quantum) when using the CPU. Alternatively executing very short periods of time.

## Multitasking
To minimize the response time of the process.

**Disadvantages**
- A single process cannot perform multiple tasks simultaneously. 
- Context switching between processes is a heavy task(programs cross over.)
- Data sharing between processes is difficult.
&rarr; the memory space they occupy is independent.
- Dual-core processors have been released.
&raar; improving the performance of a single CPU has trouble such as overheating.

### Thread
A process can have more than one thread.
Unit of execution(CPU).
Context switching between threads of the same process is lightweight.
Threads share the memory space of the process they belong to.
&rarr; Threads also have. their unique areas as well.(such as stacks)


## Multithreading
A single process executes multiple tasks simultaneously.
Each core executes one task in parallel.

###Extended multitasking concept: Multiple processes and threads share very short CPU time slices.

## Multiprocessing 
A system that utilizes two or more processors or cores.

**Summary**
Multitasking: Sharing cores
Multithreading: Dual Threads
Multiprocessing: More than 2 cores.

Building Docker image from stdin/pipe
Tags: docker, tutorial, testing
Published: 2023-02-28 06:51:03

Using `-` as `docker build` parameter, you can pipe in any text as your Dockerfile.

I use this trick to quickly test parts of a Dockerfile.

e.g.:

```bash
# Build the image, with '-' + heredoc as input
# Works the same with pipe input
docker build --tag klo2k/test - <<'EOT'
FROM ubuntu:latest

# Some complicated looking stuff you wanna try out quickly
RUN <<'EOS' /bin/bash
  echo "${HOSTNAME}" > /tmp/out
EOS

CMD echo "Build: $(cat /tmp/out) Run: ${HOSTNAME}"
EOT

# Run
docker run --rm -it klo2k/test
```

Example Output:
```bash
Build: buildkitsandbox Run: a16cd7dc16ed
```

Configurando Swagger Springfox em um projeto Spring Boot
Tags: swagger, springboot, java
Published: 2023-02-28 06:07:52

O Swagger é uma ferramenta de software que permite documentar APIs de maneira fácil e padronizada. O Springfox é uma biblioteca que pode ser integrada com o Spring Boot para gerar a documentação da API usando o Swagger.

Aqui estão os passos para configurar o Swagger Springfox em um projeto Spring Boot:

#### Adicione as dependências necessárias

O primeiro passo é adicionar as dependências necessárias ao arquivo pom.xml (no caso de projetos Maven) ou build.gradle (no caso de projetos Gradle). As dependências são:

```xml
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.9.2</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.9.2</version>
</dependency>
```
#### Configure o Swagger

Em seguida, é necessário configurar o Swagger em sua aplicação Spring Boot. Isso pode ser feito criando uma classe de configuração com a anotação `@EnableSwagger2`:

```java
@Configuration
@EnableSwagger2
public class SwaggerConfig {    
    @Bean
    public Docket api() { 
        return new Docket(DocumentationType.SWAGGER_2)  
          .select() 
          .apis(RequestHandlerSelectors.any())              
          .paths(PathSelectors.any())                          
          .build();                                           
    }
}

```
A classe Docket é usada para configurar as opções do Swagger, como as APIs e os endpoints a serem documentados.

#### Anote os controladores

Por fim, é necessário anotar os controladores da API com as anotações apropriadas do Swagger. Por exemplo:

```java
@RestController
@RequestMapping("/api")
@Api(value = "API de exemplo", description = "Exemplo de API com Swagger")
public class ExemploController {
    @ApiOperation(value = "Exemplo de endpoint", response = String.class)
    @GetMapping("/exemplo")
    public String exemplo() {
        return "Exemplo de API com Swagger";
    }
}

```

A anotação `@Api` é usada para definir o valor e a descrição da API, enquanto a anotação `@ApiOperation` é usada para definir o valor e o tipo de resposta de um endpoint.

Com esses passos, o Swagger Springfox deve estar configurado e pronto para uso em sua aplicação Spring Boot. Para acessar a interface do usuário do Swagger, basta acessar a URL `http://localhost:<porta>/swagger-ui.html`, onde `<porta>` é a porta na qual sua aplicação Spring Boot está sendo executada.

### Monday
Today I went to Bern for our Montly Breakfast meeting. It was weird because it was the first one with our new manager. Our previous manager decided to do a step back and he is our colleague again.

The location was very nice. On the top of Bern but very easy to arrive with the public transport.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/nky7tonv0us1o1rljxrt.jpeg)

**Mood:** 🙃

### Tuesday

I went to Italy to found our new subsidiary for our startup. I left Zurich, changed the train in Milan and went to Bologna.
I met my co-founder Marta and other two partners.
We spent time together in the afternoon, after lunch, and Marta and me went to Padova to meet our lead social strategist.
In the evening we went to Vicenza (Marta and me) and we worked together again.

**Mood**: 🚄

### Wednesday

I worked in the morning from Vicenza and I worked mainly on Brandplane.
I added a couple of AI tools and I reorganized the navigation bar to group these tools together.

Then, I left Vicenza for coming back to Zurich.
On the train I studied a lot OpenAI from the official documentation and I took a lot of notes on my Notion.

**Mood: 🧑‍💻**

### Thursday

I was a little bit tired after three days far away from home.
By the way I worked a little bit on Brandplane and in the afternoon I did a call about the onboarding system.
We need to rearrange everything on this special feature. We will work on it in another meeting the next week.

**Mood: 🏗️**

### Friday

In the morning I recorded a demo video for [Corsi.it](http://Corsi.it). I checked if everything works on my machine and if the settings are good or not for them. I wait a feedback from them.

For the rest of the day I worked for a new project as freelance. The project is an API (an Azure Function with a lot of endpoints) but the name of the customer is under NDA.

I will publish some posts about Azure Functions and API in the next few weeks.

**Mood: 🥶**

Sernam: The Easy Way to Generate Unique Usernames with Javascript and NodeJS
Tags: node, javascript, username, webdev
Published: 2023-02-28 05:00:23

## Are you tired of coming up with usernames for your users or yourself? Do you want a quick and easy way to generate unique usernames without having to spend a lot of time thinking about it? Look no further than [**Sernam**](https://www.npmjs.com/package/sernam), the username generator for Javascript and NodeJS.

---

> [**Sernam**](https://www.npmjs.com/package/sernam) is a lightweight and easy-to-use package that can generate single or multiple usernames from a given name. All you have to do is import it and pass in the name as a parameter. **Sernam** will then generate a unique username based on that name, and you can choose whether to include symbols and numbers in the generated username.

---

To get started with **Sernam**, simply install it using npm:

```
$ npm i sernam
```

Once installed, you can import and initialize **Sernam** in ES6:

```
import sernam from "sernam"
const options = {
  symbols: true,
  numbers: true,
}
const sn = sernam(options)
```

Or in CommonJS:
```
import("sernam").then(({ default: sernam }) => {
  const options = {
    symbols: true,
    numbers: true,
  }
  const sn = sernam(options)
})
```
**Sernam** accepts an options object with two boolean properties: symbols and numbers. If you don't pass any options object, the generated usernames will not include symbols and numbers by default.

---

To generate a single username, use the .generateOne() function:

```
let username = sn.generateOne("Firstname Lastname")
```
To generate multiple usernames, use the .generateMany() function:

```
let usernames = sn.generateMany("Firstname Lastname", 10)
```
In both cases, Sernam will generate unique usernames based on the given name.

---

**Sernam** is licensed under the MIT license, which means you can use it for any purpose, commercial or non-commercial, as long as you include the license in your project.

> **In conclusion**, if you're looking for a quick and easy way to generate unique usernames, **Sernam** is the way to go. With its simple API and customizable options, **Sernam** can save you time and hassle when it comes to username generation.
Software Design Patterns: An Overview and When to Use Them
Published: 2023-02-28 05:00:00


Software design patterns are reusable solutions to common problems in software design. They provide a way to structure code in a way that is scalable, maintainable, and flexible. In this post, we'll take a look at some common software design patterns and when to use them.

Singleton: The singleton pattern is used to ensure that a class has only one instance, and to provide a global point of access to that instance. This is useful when you want to make sure that only one instance of a resource or service is created, to avoid conflicts or duplication.
Factory: The factory pattern is used to create objects in a super class, but allow subclasses to alter the type of objects that will be created. This is useful when you want to create objects that belong to a specific family, but you don't want to specify the exact class of object that will be created.
Observer: The observer pattern is used to define a one-to-many dependency between objects, so that when one object changes state, all of its dependents are notified and updated automatically. This is useful when you want to update multiple objects in response to a change in another object.
Decorator: The decorator pattern is used to add new behavior to an existing object dynamically. This is useful when you want to add functionality to an object without changing its implementation.
Command: The command pattern is used to encapsulate a request as an object, allowing you to parameterize clients with different requests, queue or log requests, and support undoable operations. This is useful when you want to abstract the details of a request and give it a separate object to handle it.
Conclusion

Software design patterns are reusable solutions to common problems in software design. By understanding and using these patterns, you can design more scalable, maintainable, and flexible code. It's important to choose the right design pattern for the problem at hand, as different patterns are better suited to different situations.
