What is Dynamic Proxy❓

A proxy, in its most general form, is a class functioning as an interface to something else. ↗️

The proxy could interface to anything :
• A network connection 🌐
• A large object in memory 🗂
• A file 📄
• Some other resource that is expensive or impossible to duplicate. 💸

🔹🔸🔹🔸🔹🔸

One way of thinking about proxies, is by the analogy to The Matrix 🕶 by Krzysztof Koźmic 🤔 :

“People in the matrix aren’t the actual people ( “The spoon does not exist”, remember❓)

They’re proxies to the actual people that can be… wherever.🌍

They look like ones, they behave like ones, but at the same time, they are not them actually.🙅🏻‍♂️

Another implication is the fact that different rules apply to proxies.✳️

Proxies can be what the proxied objects are, but they can be more (flying, running away from bullets, that kind of stuff).✈️

One more important thing, is that proxies ultimately delegate the behavior to the actual objects behind them (kind of like – “if you’re killed in the matrix, you die in the real life as well”☠️).”

A dynamic proxy is a proxy that is generated on the fly at runtime. ✅

Writing middleware for use in Express.js apps 🔥

Overview 🔎
Middleware functions are functions that have access to the request object (req), the response object (res), and the next function in the application’s request-response cycle.

The next function is a function in the Express router which, when invoked, executes the middleware succeeding the current middleware. ⏭

Middleware can perform 💎
• Execute any code.
• Make changes to the request and the response objects.
• End the request-response cycle.
• Call the next middleware in the stack.

🔸🔹🔸🔹

Configurable middleware 📥
If you need your middleware to be configurable, export a function which accepts an options object or other parameters, which, then returns the middleware implementation based on the input parameters.

in my-middleware.js

module.exports = function(options) {
  return function(req, res, next) {
    // Implement the middleware function 
    next();
  }
}

🔸🔹🔸🔹

Usage Middleware 📤
The middleware can now be used as shown below.

const mddleware = require('./my-middleware.js')
app.use(mddleware({ option1: '1', option2: '2' }))

Fluent Validation ⚠️

A small validation library for .NET that uses a fluent interface and lambda expressions for building validation rules. 🚫

NuGet Packages :

Install-Package FluentValidation

For ASP.NET MVC integration :

Install-Package FluentValidation.MVC5

For ASP.NET Core :

Install-Package FluentValidation.AspNetCore

🔹🔸🔹🔸

Example :

public class PersonValidator : AbstractValidator<Person>
{
    public PersonValidator()
    {
        RuleFor(x => x.ID).NotEmpty();

        RuleFor(x => x.FirstName)
            .NotEmpty()
            .WithMessage("{PropertyName} is required !")
            .MinimumLength(5)
            .WithMessage("Minimum length for {PropertyName} is {MinLength} !");

        RuleFor(x => x.LastName)
            .NotEmpty()
            .WithMessage("{PropertyName} is required !")
            .MinimumLength(5)
            .WithMessage("Minimum length for {PropertyName} is {MinLength} !");

        RuleFor(x => x.Email)
            .NotEmpty()
            .WithMessage("{PropertyName} is required !")
            .EmailAddress()
            .WithMessage("{PropertyName} is not valid !");
    }

Polly 🕊

Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback in a fluent and thread-safe manner. ♻️


Installing via NuGet 🗃 :

Install-Package Polly

Usage :

public class Mailer
    {
        public static bool SendEmail()
        {
            Console.WriteLine("Sending Mail ...");

            // simulate error
            Random rnd = new Random();
            var rndNumber = rnd.Next(1, 10);
            if (rndNumber != 3)
                throw new SmtpFailedRecipientException();

            Console.WriteLine("Mail Sent successfully");
            return true;
        }
    }

We retry to send the email 3 times if something failed ❌ :

var policy = Policy.Handle<SmtpFailedRecipientException>().Retry(3);
policy.Execute(Mailer.SendEmail);

JavaScript - Map vs. ForEach 🗺

What’s the difference between Map and ForEach in JavaScript❓

Let’s first take a look at the definitions on MDN 🌀 :
• forEach() ➖ executes a provided function once for each array element.

• map() ➖ creates a new array with the results of calling a provided function on every element in the calling array.

What exactly does this mean❔

Send ETag headers in ASP.NET Core ✨

ASP.NET Core doesn’t add an ETag header automatically to HTTP responses from MVC action methods or Razor Pages. ❌

We have to implement that ourselves to provide the users with true Conditional GET support that honors the If-None-Match request header. ✅

Wouldn’t it be nice if all we had to do was to register it using app.UseETagger() like this❓

Automatic ModelState Validation in ASP.NET MVC 🔥

How many times have you seen or written code like this ♻️ :

[HttpPost]
public ActionResult Index(SomeModel model)
{
    if (ModelState.IsValid)
    {
        return View();
    }   

    // do something
    return RedirectToAction("index");
}

Stop repeating ModelState checks in your ASP.NET MVC controller actions. ❌

Wouldn’t it be nice if all we had to do was like this ? ⚡️

[HttpPost]
[ValidateModelState]
public ActionResult Index(SomeModel model)
{
    // if we get here, ModelState is valid
    // save to db etc.
    return RedirectToAction("index");
}
