Say good bye to controllers: C# Minimal APIs

Imagine being able to define an entire API endpoint in a single line of code, without controllers. Yes, you read that correctly—just one line. This isn't just a pipe dream; it's the reality of what you can achieve with Minimal APIs in C#:

var builder = WebApplication.CreateBuilder(args);

// ConfigureServices

var app = builder.Build();

app.MapGet("hello", () => "Hello dev.to!");

app.Run();

From setting up the web application builder to defining a simple "hello" endpoint that greets with "Hello dev.to!"—this code is the epitome of succinctness. By trimming down the fat, we are left with the purest parts of the framework, enabling us to focus on what truly matters: creating.

The perks of Minimal APIs are manifold:

Simplicity: that welcomes newcomers and pleases seasoned architects.

Performance: gains from a reduced footprint.

Flexibility: to scale from a microservice to a full-fledged application.

Diving into Minimal APIs doesn't require an expedition into unknown territories. Armed with the .NET 6 SDK or later, and your favorite text editor or IDE, you're well-equipped to embark on this journey.

As you embrace this paradigm, you may find yourself curious for more—more insights, more nuances, more knowledge. For those hungry minds, I recommend watching a detailed exploration on YouTube that demystifies Minimal APIs even further. Check out this video for an in-depth understanding and practical demonstrations that will elevate your mastery of Minimal APIs.

In closing, Minimal APIs are not just a feature; they are a philosophy. A philosophy that champions the virtues of less is more, proving that sometimes, the minimal approach can yield the maximum impact.
