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 Custom Validation for Template Driven forms 🅰️

This article consists an example for a custom email validator using regex. 🌐

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. 💎

Usage :
<input type="email" emailvalidator>

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
