Architecting Services with Design Patterns 💎

As the number of your services expands you're going to need to start thinking about how to organize them. 🗂

Applying these two design patterns can help, provided you understand all their variations. ✅

With the current set of tools that come with the Microsoft .NET Framework, it's easy to create a service. ⚙️

But it's also easy to create what both Nayaki Nayyar and Benjamin Moreland described as a "junk drawer of services." 👾

If you're going to avoid that as the number of services in your organization increases, then you need to think about your architecture. 🤔

Use T4MVC to Remove Magic Strings in ASP.NET MVC Apps 🎩

ASP.NET MVC has a fascination with magic strings. ❌

Basically any time you need to specify an action, a view, or controller, you use a magic string ✨ :

return RedirectToAction("Index", "Home", new { id = 4 });

return View("Details");

@Html.ActionLink("Back to details", "Detals", "User", new {id = 12}, new {@class = "backlink"});

@using (Html.BeginForm("Details", "User", FormMethod.Post))

The problem with magic strings is the same problem that ViewBag has ⚠️ :

1️⃣ There's no type checking.

2️⃣ The developer won't catch these errors until runtime, and sometimes not at all.

🔹🔸🔹🔸

T4MVC aims to remove magic strings from MVC and replace them with strongly-typed ActionResults. ✅

It adds a bunch more overloads to methods such as ActionLink(), BeginForm(), and RedirectToAction() so that they can now accept ActionResults as parameters. 🗃

Thereby making them strongly-typed and removing their dependency on magic strings. 💎

Most importantly, it means we can take the above code samples and refactor them to look like this 🤙🏻 :

return RedirectToAction(MVC.Home.Index(4));

return View(MVC.User.Views.ViewNames.Details);

@Html.ActionLink("Back to details", MVC.User.Details(12), new {@class = "backlink"});

@using (Html.BeginForm(MVC.User.Details(), FormMethod.Post))

Insidious Dependencies 🤷🏻‍♂️

In the last year or so I’ve really seen the light on how to really write loosely-coupled code. 💎

I thought I knew something about this concept before – I mean, I knew loose coupling was good, generally speaking, and I knew data abstraction was one of the key ways to limit dependencies between classes. ✅

However, I didn’t realize that I was unintentionally adding all kinds of coupling into my applications despite my best efforts to the contrary. ⛔️

Let’s talk about some dependencies, including some obvious ones, as well as some insidious dependencies that lurk in most applications I’ve seen. 🗂

Insidious dependencies ❌ :
• File System
• Email
• Web Service & Requests
• DateTime.Now
• Configuration
• New ...

How to Stop Using Callbacks and Start Living ⚛️

Javascript has two major ways of dealing with asynchronous tasks - callbacks and Promises. 🤝

In general Promises are considered easier to use and to maintain than callbacks. ✅

But in reality even Promises alone won’t make you happy. 🤬

Asynchronous code may still be quite difficult to read and to understand. 🤯

Therefore third-party libraries, e.g. co, provided means to write a synchronous-like asynchronous code. 🗃

I personally prefer everything in the world to be as clear and beautiful as redux-saga. ✨

But not everybody is lucky to work with React and Redux to be able to use sagas. ⛔️

This article will show that in modern Javascript it is not difficult to write a well structured and easy to understand asynchronous code without using any third-party libraries.💎
