Optimizing JavaScript Code: Embrace Async/Await for Clarity
Tags: async, await, javascript, typescript
Published: 2023-09-01 07:42:44

When it comes to writing clean and maintainable JavaScript code, one of the best practices you can adopt is to leverage the power of async/await. In this tip, we'll explore why using async/await is a game-changer and how it can make your code more accessible and easier to read for developers of all skill levels.

## The Power of async/await

Async/await is a modern JavaScript feature that simplifies asynchronous programming. It's particularly useful when dealing with tasks like making network requests, handling file operations, or managing timers. Instead of relying heavily on promise chaining, async/await allows you to write asynchronous code that closely resembles synchronous code. 

## Readability and Accessibility

One of the most significant advantages of async/await is its ability to enhance the readability of your code. By using async/await, you can write asynchronous operations in a more linear and structured manner. This makes your code easier to follow, understand, and maintain. Even developers who may not be well-versed in JavaScript will find it more approachable.

## Reducing Callback Hell

Callback hell, also known as the "Pyramid of Doom," occurs when you nest multiple callbacks within each other. This can make your code hard to read and debug. Async/await helps you avoid this problem by allowing you to write asynchronous code in a sequential and structured way. This results in cleaner and more organized code, reducing the likelihood of errors.

## Error Handling

Async/await also simplifies error handling. You can use try/catch blocks to catch and handle errors in a straightforward manner. This leads to more robust code that's easier to troubleshoot.

## Getting Started with async/await

To start using async/await in your JavaScript projects, you'll need to define functions as `async` and use the `await` keyword inside them to wait for promises to resolve. This approach will make your codebase more consistent, readable, and maintainable.
  

```js
// define a named function
async function getInformation(){
// a network call - 
const response = await fetch('...')
// the results will be available after the promise resolves above
console.log(await response.json())
}
//or use an arrow function
const getInformation= async()=>{
// same code implemented as above
}


```
   
In summary, i highly recommend embracing async/await where possible in your JavaScript code. By doing so, you'll not only make your code more accessible to developers who may be less familiar with JavaScript but also improve the overall readability and maintainability of your codebase. So, why not start integrating async/await into your projects today and experience the benefits firsthand?

Why should you go for good quality used engines?
Published: 2023-09-01 07:36:39

Quality is an important factor and you need to consider it before buying good [quality used engines](https://www.swizzauto.com/). Before being purchased, used engines go through a series of inspections, tests, and examinations to guarantee that they are in outstanding condition. The reliability of this service will save you both time and money in the long run. When you buy a used engine, you keep it from being dumped in a landfill and adding to the overall amount of garbage in the world.

OpenStack Sflow Entegrasyonu Openvswitch
Tags: cloud, network, opensource, linux
Published: 2023-09-01 07:24:32

OpenStack üzerinde çalışan makinalarımızın network trafiklerini **openvswitch** üzerinden **sflow** kullanarak izleyebilmekteyiz.

**ovs-vsctl** komutunu kullanarak openvswitch yönetimini gerçekleştirebiliriz. Aşağıdaki komut ile sflow özelliğini açalım.

``` bash
ovs-vsctl -- --id=@sflow create sflow agent=${AGENT_IP}     target="\"${COLLECTOR_IP}:${COLLECTOR_PORT}\"" header=${HEADER_BYTES}     sampling=${SAMPLING_N} polling=${POLLING_SECS}       -- set bridge deren-bridge sflow=@sflow
```

**Örnek**
``` bash
ovs-vsctl -- --id=@sflow create sflow agent=ens19     target="\"192.168.2.91:6343\"" header=128     sampling=10 polling=30       -- set bridge br-int sflow=@sflow
```


uyguladığımız sflow konfigürasyonumuzu aşağıdaki komutu kullanarak görebiliriz.

``` bash
ovs-vsctl list sflow
```
```
root@openst domains(keystone)# ovs-vsctl list sflow
_uuid               : 7740265f-ef21-427e-919b-8b7c80e423ed
agent               : ens19
external_ids        : {}
header              : 128
polling             : 30
sampling            : 10
targets             : ["192.168.2.91:6343"]

```

Ayarlar, interface ve target ip ve port bilgisi doğru ve erişilebilir ise sflow collector makinanıza sflow verileri ulaşmalıdır.

sFlow toplayacak makinanızdan aşağıdaki komut ile kntrol sağlayabilirsiniz.


``` bash
tcpdump port <collector_listener_port> | grep <openstack_ip>

tcpdump port 6343 | grep 192.168.2.91
``` 

bu işlem sonucunda ip adresinizden gelen sflow verisi görürseniz başarılı bir şekilde kurulum sağlamışız demektir :)

What is JavaScript?

JavaScript is used to add functionality to web pages. Let me give you an analogy.

Think of a building. 

![Building being constructed](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/jq2presmv19pj46gitza.png 'Building being constructed')

A building in the real world is like a web page on the internet. It has a skeleton or structure – the framing and foundation of the building (HTML).

It can have pretty walls, windows, and tiles as well that finish it out and make it look nice (CSS).

![House tiles](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/qyxlnonpxnscy9kaulit.png 'House tiles')

And it can have certain functionality, like being a home, a hospital, or a supermarket (JavaScript).

![Elevators of a house](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/w696b1x0dhkg534cqx2e.png 'Elevators of a house')

For example, when we press the elevator button, it comes to pick us up. JavaScript would enable this in our analogy.

---

## **Introduction**

As I’d mentioned previously, I’ll be using the **[FoodData Central](https://fdc.nal.usda.gov/api-guide.html) API** provided by US Dept. of Agriculture for accessing the nutritional information about the food.

I was initially planning to download and dump it’s branded and foundational food database in a PostgreSQL database, but decided against it due to certain memory constraints as I’m using the (free) 500MB PostgreSQL DB by Supabase for prototyping this application, while the unzipped size of branded food database alone is 2.7GB.

Instead i’ll be using it’s free API, which has a pretty generous rate limit of [1k requests per hour per IP address](https://fdc.nal.usda.gov/api-guide.html#bkmk-4), which is perfect for building and testing the prototype.

## **Updates**

1. I was able to understand the basics of it’s search API endpoint (i.e. `/v1/foods/search`), including how the response data is structured and how to implement pagination for the endpoint and based on this, I was able to design a basic layout for the [**food item search component**](https://twitter.com/n00bgineer/status/1697507440995266677?s=20), which can be used to add the number of servings for a food item or look for a food item’s nutritional information. 

## **Next steps**

1. Now, I’ll try to implement the search page which will be used to search the food items and later I’ll update the food item schema to allow users to add the search (or scanned) food item to their food consumption history.
2. After I’ve built the **`FoodSearchPage`** , **`FoodSearchCell`** & **`FoodSearch`** components along with the respective server-side endpoints, I will test out the Google’s labeling API for the food scanning feature, which will allow users to scan their food and get it’s nutritional information.

Unit Testing ASP.NET Core Web APIs with xUnit and Moq
Published: 2023-09-01 06:20:22

Unit testing is a crucial part of software development that ensures the reliability and functionality of your code. In this tutorial, we'll explore how to unit test ASP.NET Core Web APIs using the xUnit testing framework and Moq mocking library. We'll cover setting up the testing environment, writing test cases, and using Moq to mock dependencies.

## Prerequisites:

- Basic understanding of ASP.NET Core and C#
- Visual Studio or Visual Studio Code installed
- .NET Core SDK

## Setting Up the Project:

Create a new ASP.NET Core Web API project or use an existing one.

## Installing xUnit and Moq:

Open the project in Visual Studio or Visual Studio Code and install the required NuGet packages.

## dotnet add package xunit

```bash
dotnet add package xunit
dotnet add package xunit.runner.visualstudio
dotnet add package Moq
```

## Creating Unit Test Project:

Add a new class library project to your solution for unit tests.

## Writing Test Cases:

In the unit test project, create test classes for your API controllers. Write test methods for various scenarios.

```csharp
// ExampleControllerTests.cs
public class ExampleControllerTests
{
    private readonly Mock<IExampleService> _mockService;
    private readonly ExampleController _controller;

    public ExampleControllerTests()
    {
        _mockService = new Mock<IExampleService>();
        _controller = new ExampleController(_mockService.Object);
    }

    [Fact]
    public async Task Get_ReturnsOkResult()
    {
        _mockService.Setup(service => service.GetDataAsync()).ReturnsAsync(new List<string>());

        var result = await _controller.Get();

        Assert.IsType<OkObjectResult>(result);
    }

    // Add more test methods
}
```


## Running Tests:

Use the test runner in your development environment to execute the unit tests. Observe the test results.


## Mocking Dependencies with Moq:

Utilize Moq to mock dependencies such as services and repositories. Define expected behavior for these mocks in your test methods.



## Advanced Testing Scenarios:


Explore more complex scenarios like testing exceptions, handling edge cases, and testing routes with attributes.



## Best Practices:


Discuss best practices for naming test methods, organizing test projects, and maintaining a comprehensive test suite.


## Conclusion:


Unit testing ASP.NET Core Web APIs with xUnit and Moq ensures the reliability of your codebase. By following these steps, you can efficiently write and execute unit tests, boosting the overall quality of your application.
