C# Tip: use IHttpClientFactory to generate HttpClient instances
Tags: csharp, dotnet
Published: 2022-07-25 12:22:49

## The problem with HttpClient

When you create lots of `HttpClient` instances, you may incur **Socket Exhaustion**.

This happens because sockets are a finite resource, and they are not released exactly when you 'Dispose' them, but a bit later. So, when you create lots of clients, you may terminate the available sockets.

Even with `using` statements you may end up with Socket Exhaustion.

```cs
class ResourceChecker
{
    public async Task<bool> ResourceExists(string url)
    {
        using (HttpClient client = new HttpClient())
        {
            var response = await client.GetAsync(url);
            return response.IsSuccessStatusCode;
        }
    }
}
```

Actually, the real issue lies in the disposal of `HttpMessageHandler` instances. With simple `HttpClient` objects, you have no control over them.

## Introducing HttpClientFactory

The `HttpClientFactory` class creates `HttpClient` instances for you.

```cs
class ResourceChecker
{
    private IHttpClientFactory _httpClientFactory;

    public ResourceChecker(IHttpClientFactory httpClientFactory)
    {
        _httpClientFactory = httpClientFactory;
    }

    public async Task<bool> ResourceExists(string url)
    {
        HttpClient client = _httpClientFactory.CreateClient();
        var response = await client.GetAsync(url);
        return response.IsSuccessStatusCode;
    }
}
```

The purpose of `IHttpClientFactory` is to solve that issue with `HttpMessageHandler`.

An interesting feature of `IHttpClientFactory` is that you can customize it with some general configurations that will be applied to all the `HttpClient` instances generated in a certain way. For instance, you can define HTTP Headers, Base URL, and other properties in a single point, and have those properties applied everywhere.

## How to add it to .NET Core APIs or Websites

How can you use HttpClientFactory in your .NET projects?

If you have the Startup class, you can simply add an instruction to the `ConfigureServices` method:

```cs
public void ConfigureServices(IServiceCollection services)
{
    services.AddHttpClient();
}
```

You can find that extension method under the `Microsoft.Extensions.DependencyInjection` namespace.


## Wrapping up

In this article, we've seen why you should not instantiate HttpClients manually, but instead, you should use `IHttpClientFactory`. 

Happy coding!

Working with Multiple Elements in Selenide
Tags: testing, java, webdev, tutorial
Published: 2022-07-25 12:19:37

In this Selenide tutorial series post, we will learn how to work with multiple elements using the `$$` sign.

### $$ (css selector)
When working with individual element in Selenide, we use $ sign which returns us a single element back. To work with multiple elements we need to use `$$` sign to get Elements Collection returned. Let’s take a look at an example –

```
ElementsCollection linkLists = $$("#primary-menu li[id*=menu-item]");
```

The above code will return all the elements matching the css selector as a collection of elements. You can then use this to iterate through the elements or get the text and so on..

---
 
### $$ (By)
By default `$$` uses a css selector but you do have an option to provide any other selector as well such as `XPath`, `name` etc..

```
ElementsCollection linkLists = $$(By.xpath("//li[starts-with(@id, \"menu-item\")]"));
```

A Developer with a difference
Tags: devjournal, productivity, discuss
Published: 2022-07-25 12:11:00

There are tons of developers currently flocking the talent market, but there is still a tussle to get a developer that could actually make a difference. I once worked with a client who opened up to me that getting a developer you can trust is difficult.

What the talent market are developers with a difference, that actually knows what they are doing and have the necessary qualities and attitude to get it done. Such developers are rare and such developers should be cherished when seen or hired.

By God's grace, I am such a developer, not just skilled in the work, but possess the requisite attributes and qualities needed to make one a developer with a difference. 

I worked on a project with a client. First of all, for some reasons the client explained, the pay wasn't up to what was charged but pleaded to make it up to me later on. I took on the Job. Then the timeline for the Job to be completed was also too close and therefore a fast developer that could work under pressure was a perfect fit for the Job. I completed a full-stack Job under two weeks and the Client was wowed.

Since then the Client has not stopped reaching out to me to work on some other projects for him. That's how to be a developer with a difference, Know the Job and have the Qualities.

Inspired by Carlos [(https://www.toptal.com/resume/carlos-arauz-soliz)], I know I can be one of Toptal's top 3% of global talent.
Rails 7 Latest version: What’s new?
Tags: ruby, rails7, webdev, programming
Published: 2022-07-25 12:06:24

Finally released, Rails 7.02 includes significant updates and innovative new features that should accelerate and simplify development at the core level.
The previous 7.0 release included improvements including per-database connection switching and hierarchical database sharding.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0682ml2tqvd9ktqsbz8u.png)

Many aspects of Rails 7 are said to be superior to the previous version, Rails 6.1.4, including improved JavaScript support and a switch from classic mode to Zeitwerk. What is currently known about just the updated design is as follows:

## To import-mapped as a default Hotwire
Imported maps are being used in place of Webpacker, Turbolinks, and UJS by default. This could be the major shift in the upcoming Rails update and will likely be the major update since the software's debut in 2005.

## The application running in Zeitwerk mode is required.
Including the new upgrade, any apps that are presently functioning in Classic mode must transition to Zeitwerk mode. 
Developers, don't freak out! Numerous Rails apps have indicated that somehow this transition is seamless so any issues since then have become easy to resolve.

## Autoloading was fixed during setup and installation
Furthermore, apps outside of preparing sections should be able to autoload reloadable constants.

## Mistake in preview generation
When a previewer process exits with a non-0 status code, the PreviewError exception is raised in Rails 7. Instead of having to cope with unpleasant surprises later on, this functionality enables developers to plan for preview problems. Eventually, this practice will make the life of Ruby on Rails Developers quite easier.

## Loading Parallel Query
You would have to run each question in a series after performing the prior difficult, unrelated queries, which would take a lot of time. Seven queries can now be usually correlated and sequentially with Rails, maximizing the efficiency.

The biggest update to Rails to date is expected to bring about significant advancements for all web developers. Moreover, Rails 7 is prominently all about the latest Rails architecture tailored to enhance the user experience and is less irritating than ever before, from Hotwire deployment to simultaneous query execution.

Custom Routes In Flask Using Flask Restful
Published: 2022-07-25 12:04:00

In this short tutorial, I'll illustrate how we can use flask to write an API; with the following goals:
a) Defining custom routes 
b) Separating routes, controllers, models, validators etc into their respective folders

I'll at a later time put up a post to aid us in understanding my style of architecture, when it comes to Flask.
<b>Defining Custom Route</b>
Let's take a hypothetical blog-site for instance. I'm assuming in your project you've got a users, comments and posts folder. The reason for this, bothers on the fact that you'd want to separate the models, routes, controllers etc for posts and users. Your users controllers would definitely concern, but not limited to; registration, login, forgot-password, change-email, etc. While those for posts would include edit-post, delete-post, create-post etc. You would agree with me that clustering this transactions in one file, would definitely wear you out, if not possibly, get you insane. FurhterMore, since Flask-Restful only supports the known HTTP-verbs, "GET", "POST" etc it'd as well not sound manageable, to define new classes for each post, delete etc operations respectively. One would think that to achieve a login and register transaction would require different classes as below (in your routes.py file);
```
routes.py
class LoginView(Resource):
    logging.basicConfig(level=logging.INFO)
    logging.info("Entered the LoginView...")

    def login(self):
        print("\n\t Login route....")

class RegisterView(Resource):
    logging.basicConfig(level=logging.INFO)
    logging.info("Entered the RegisterView...")

    def register(self):
        print("\n\t Register route....")
```
This problem can simply be solved, pythonically, as below;
```
from flask_restful import (
    Resource,
    request
)
import logging

from ..models.models import Users
class AuthViews(Resource):
    logging.basicConfig(level=logging.INFO)
    logging.info("Entered the auth views...")

    def login(self):
        print("\n\t Login route....")


    def register(self):
        print("\n\t Register route....")


    def post(self):
        print("\n\t Login-Data: ", request.data)
        print("\n\t Login-Data: ", request.url)
        url = request.url
        if "login" in url:
            login = self.login()
        elif "register" in url:
            register = self.register()
        elif "forgot-password" in url:
            register = self.forgot_password()
        else:
            etc....

auth_routes = ["/auth/register", "/auth/login"]
```
Then in your app.py file, you'd register your resource like so;
```
...
from routes.routes import AuthViews, auth_routes
app = Flask(__name__)
api = Api(app)
api.add_resource(AuthViews, *auth_routes)
```
Thanks. Next, I'll show you how to define models, using PyMongo.

JS detect mobile device
Tags: javascript, webdev, tutorial, programming
Published: 2022-07-25 11:31:00

Hey there all! I guess this is kinda like my _Hello world_ of writing posts, so don't be too harsh 😄

## Disclaimer
I am not claiming this is the best way & I wouldn't call it the most complete way to check if a device is a "popular-ish" mobile device. But it is simple and should work correctly for the most part. (If you do see/find an issue, please feel free to let me know) Last but not least, I did not come up with this. I found it and will share a link _here_ if and when I find the post again.

## Introduction
Firstly, if you want to apply styles to something depending on actual screen sizes. _**(my opinion)**_ Use the built-in CSS media queries, very reliable once you understand them.

The use case for this would be more if you want certain functionality to only trigger on a mobile or a desktop.

Now that I have that out of the way, here is the solution and a minor explanation after.

```javascript
var agentDetails = navigator.userAgent;

function isMobile() {
  if(/Android|Mobi|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(agentDetails) ) {
    // Hit here if the device is a "popular-ish" mobile device
  } else {
    // Hit here if the device is  NOT a "popular-ish" mobile device
  }
}
```

## Explanation
Ok so let's start dissecting this...

The first line `var agentDetails = navigator.userAgent` gets the [user agent data](https://developer.mozilla.org/en-US/docs/Web/API/Navigator/userAgent) for the browser used.

In short, this gets the `Platform, Security, OS-or-CPU, Localization, revision-version-number` relavent to the current device. (at time of writing)
This will contain the info we want to see and will be the White text in the Codepen below.

The second important part is the `if()` statement. The string in the `if()` has a `/` at the start and a `/i` at the end (the `/i` at the end, just makes it case-insensitive) & is delimited by pipes ("|").
This creates a [regular expresion](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions) of the string. (This could be an entire other series 😅)

The reason we make it a regular expression is so that we can use the `.test()` method against it which "executes a search for a match between a regular expression and a specified string." you can read more about it [here](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp/test)

So if the user agent data returns for instance:
"Mozilla/5.0 (iPad; CPU OS 15 5 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148"

This would be an iPad, so it would return true as the string we are checking (user agent) & the regular expression both contain the word iPad.

##Conclusion
I think that is it, as promised here is the Codepen I created, it's not fancy, it's not pretty, but it works.
As seen in the user agent documentation, this info can be altered by the user or third-party apps. So beware, results may vary.

CSS Selectors.
Tags: css, webdev, beginners, tutorial
Published: 2022-07-25 11:28:56

CSS selectors, these are used to select a particular or group of tags sharing some common thing like class name, id, (siblings), tag  name.

Selectors follow specificity (say priority), for example if there is a tag having class = `a` and id = `b`. If you're selecting a element with `a` and `b` then CSS property given to `b` are applied.

You can read more about css selectors [here](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors).


### Basic Selector

#### Universal Selector
selects all the elements, denoted by `*`.

#### Type Selector
This selector selects all elements with same tag name. 
`tag_name`.

#### Class Selector
This selector selects all elements with class name that is selected.
`class_name`.

#### ID Selector
This selector selects element with a id.
_many elements can have one id, but use class for this, it's just convention._
`id_name`.
Logging navigable trees in Javascript
Published: 2022-07-25 11:25:00

To produce navigable trees from any Javascript object, use 𝗰𝗼𝗻𝘀𝗼𝗹𝗲.𝗱𝗶𝗿. You will get an interactive list of all object properties.

One nice thing about this method is that it can handle DOM elements too. So instead of getting the original HTML elements, you get a JSON representation of the object, as you can see in the snap below how different the document object looks with 𝗰𝗼𝗻𝘀𝗼𝗹𝗲.𝗱𝗶𝗿 as opposed to 𝗰𝗼𝗻𝘀𝗼𝗹𝗲.𝗹𝗼𝗴.

It takes a second object parameter with these options:
1- 𝗱𝗲𝗽𝘁𝗵 => set it to null if you want to cover all levels recursively.
2- 𝗰𝗼𝗹𝗼𝗿𝘀
3- 𝘀𝗵𝗼𝘄𝗛𝗶𝗱𝗱𝗲𝗻 => shows non-enumerable keys and Symbols.

If you have an XML/HTML element, then use 𝗰𝗼𝗻𝘀𝗼𝗹𝗲.𝗱𝗶𝗿𝘅𝗺𝗹 instead.

Note that you could also use 𝗱𝗶𝗿 and 𝗱𝗶𝗿𝘅𝗺𝗹 directly without the need for the 𝗰𝗼𝗻𝘀𝗼𝗹𝗲 object.

Follow for more tips :)
