JavaScript — Double Equals VS Triple Equals ✨

JavaScript has two visually similar, yet very different, ways to test equality. 🤓

You can test equality with == or === 🔅


Triple Equals ✅
When using triple equals === in JavaScript, we are testing for strict equality.

This means both the type and the value we are comparing have to be the same.

Example :

77 === '77'
// false (Number v. String)

🔹🔸🔹🔸

Double equals ✅
When using double equals in JavaScript we are testing for loose equality.

Double equals also performs type coercion.

Example :

77 == '77'
// true

Import and export in ES6 📚

Export is ES6' way of saying 🗣 :

“Make this code available for other modules.”

Import is the opposite, and tries to get code from other modules.

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. ✅

Angular 4 Already has a built-in validator for this “ng-pattern”. ⚠️

But this article is more focused on creating a base for custom validators so you could improve and use it for other use cases. 💎

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);
