Objects Should Be Immutable 🤫

In object-oriented programming, an object is immutable if its state can’t be modified after it is created. 🤞🏻

In Java/C#, a good example of an immutable object is String.✅
Once created, we can’t modify its state. We can request that it creates new strings, but its own state will never change. ❌

However, there are not so many immutable classes in JDK. Take, for example, class Date. It is possible to modify its state using setTime(). 🕒

This is an incomplete list of arguments in favor of immutability ⚡️:

• Immutable objects are simpler to construct, test, and use
• Truly immutable objects are always thread-safe
• They help to avoid temporal coupling
• Their usage is side-effect free (no defensive copies)
• Identity mutability problem is avoided
• They always have failure atomicity
• They are much easier to cache
• They prevent NULL references, which are bad

Let’s discuss the most important arguments one by one. 🌀

Pose 👥

Replace any .NET method (including static and non-virtual) with a delegate. 💎

It is similar to Microsoft Fakes but unlike it Pose is implemented entirely in managed code (Reflection Emit API).✨

Everything occurs at runtime and in-memory, no unmanaged Profiling APIs and no file system pollution with re-written assemblies.⚡️


Example Usage 🔥:

Shim static property getter ⏱:

Shim dateTimeShim = Shim.Replace(() => DateTime.Now).With(() => new DateTime(2004, 4, 4));


Usage 👾:

// This block executes immediately
PoseContext.Isolate(() =>
{
// All code that executes within this block
// is isolated and shimmed methods are replaced

// Outputs "4/4/04 12:00:00 AM"
Console.WriteLine(DateTime.Now);
}, dateTimeShim);

Boost Your Vue.js Workflow With Vue CLI 3 ⚡️

We can hardly imagine modern web development without the help of Command-Line Interface (CLI) tools. 💻

They tremendously facilitate and speed up the development workflow by reducing the amount of repetitive and tedious tasks. ✅

Setting up a project manually, with all the linting, building, testing, preprocessing, optimizing, and dependency tracking features, doesn't sound like a fun job, does it❓

That's why all modern client-side development frameworks (such as Angular, React, etc.) offer their own version of CLI tools, and Vue.js is no exception. 💎

But with its latest third version, Vue CLI is going one step ahead of the others. ✨

It's now not only highly powerful and flexible, but also comes with a full-blown GUI. 🌈

Yeah, you heard right. Vue CLI 3 offers a full graphical user interface out of the box. 🌀

Domain Driven Design - Clear Your Concepts Before You Start ✨

What we traditionally do when we start a business application❓

We read the spec and find the functionalities. We break down tasks. ✅

We do the estimation. We distribute the works among team members. We design the database schema - sometimes by the team leader or sometimes by the respective developer. We start coding. 💻

So❓ What’s wrong with this approach❓We have been doing good❗️Don’t we❓

The answer is YES and NO❗️Yes we are doing good in delivering our projects. But NO❗️
We are not doing good in maintaining and extending our projects. 🤦🏻‍♂️

Think about all of the projects you have worked last few years in the traditional approach. Did you ever face any of the issues below ? 🤔

Your project has the same functionality implemented in the same way or different in different places. 👥

You have more than one object for the same item. ❌

You have objects that have properties that are not actually attributes of that object. 🙅🏻‍♂️

You have no or very poor relationship among related items. ↔️

Looking at your objects it is not possible to understand what actually the whole application is all about. 🤷🏻‍♂️

Reinforced.Typings ⚡️

Converts C# classes to TypeScript interfaces (and many more) within project build. 💎

Examples ✨ :

C# ♥️ :

[TsInterface]
public class Order
{
public string ItemName { get; set; }
public int Quantity { get; set; }
public double Subtotal { get; set; }
public bool IsPaid { get; set; }
public string ClientName { get; set; }
public string Address { get; set; }
}

[TsClass]
public class User
{
public string FirstName { get; set; }
public string Email { get; set; }
public UserType Type { get; set; }
}

[TsEnum]
public enum UserType { One, Two }


Result => TypeScript 💙 :

export interface IOrder
{
ItemName: string;
Quantity: number;
Subtotal: number;
IsPaid: boolean;
ClientName: string;
Address: string;
}

export class User
{
public FirstName: string;
public Email: string;
public Type: MyApp.UserType;
}

export enum UserType {
One = 0,
Two = 1,
}

New horizons in CSS: Houdini and the Paint API 🌈

The way we write CSS is about to change. No, I don’t mean you have to change how you write your styles, but we as developers are about to get a lot more control. 💪🏻

What am I talking about❓That would be the CSS Houdini spec and the new browser APIs that are coming out as a part of it. ✅

“You know nothing , Engineers” — HTTP [Patch] 🤷🏻‍♂️

I believe, HTTP Patch is completely misunderstood by us ( At least by some of us ). 🤔

A PATCH request is one of the lesser-known HTTP methods, but I'm including it this high in the list since it is similar to POST and PUT. ↔️

The difference with PATCH is that you only apply partial modifications to the resource. ⚡️

The difference between PATCH and PUT, is that a PATCH request is non-idempotent (like a POST request). ✅
