✅ Controller routing in 2023

Hi, as I understand it, just like everything in programming, you can do one thing in many different ways. This also works to controller routing. There are lot of ways to route your controllers in a web app. What is the most common way to route them in 2023? Setting each method from Program.cs? route attribute? maybe just with method names?

Hi, afaik you create a controllers folder and create controller in their either by keeping controller attribute over the class name or the class name ending with Controller and in program.cs you just add builder.services.AddControllers() and app.MapControllers.

i thing we talk about different things let me explain it again, what i meant so, i can

app.MapControllerRoute(
  name: "default",
  pattern: "{controller=Home}/{action=Index}/{id?}");

app.MapControllerRoute(
  name: "default",
  pattern: "{controller=Home}/{action=Index}/{id?}");

Aahh! Apologies I usually use route attributes

wwwwOP•15mo ago

So, here if i go to "/" it will load home/index

Shinigami•15mo ago

[Route("/")]

wwwwOP•15mo ago

wwwwOP•15mo ago

or like this

Shinigami•15mo ago

Yup, right!

wwwwOP•15mo ago

atleast 3 ways and i belive there is more ways to do that

Shinigami•15mo ago

I feel route attributes are cleaner, since you wouldn't clutter program.cs

wwwwOP•15mo ago

and im asking, which is most used in our time so, in case im using attributes, i don't rly need to write anyting in program.cs? like i have

using Microsoft.AspNetCore.Mvc;

namespace alpha.Controllers
{
    public class LoginController : Controller
    {
        [Route("login")]
        public string Index() => "Login page";
        [Route("info")]
        public string Info() => "Info page";
    }
}

using Microsoft.AspNetCore.Mvc;

namespace alpha.Controllers
{
    public class LoginController : Controller
    {
        [Route("login")]
        public string Index() => "Login page";
        [Route("info")]
        public string Info() => "Info page";
    }
}

and thats ok?

wwwwOP•15mo ago

but program.cs is like

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddControllersWithViews();
var app = builder.Build();


app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddControllersWithViews();
var app = builder.Build();


app.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

app.Run();

and controllers in this case is smthing like wrapper for different routes groupd by similar purpose

Shinigami•15mo ago

You can just do app.MapControllers(); instead of mapcontrollerroute Try adding just app.mapcontrollers(); and run the app

wwwwOP•15mo ago

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddControllersWithViews();

var app = builder.Build();

app.MapControllers();

app.Run();

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddControllersWithViews();

var app = builder.Build();

app.MapControllers();

app.Run();

using Microsoft.AspNetCore.Mvc;

namespace alpha.Controllers
{
    public class LoginController : Controller
    {
        [Route("login")]
        public string Index() => "Login page";
        [Route("registration")]
        public string Info() => "Registration page";
    }
}

using Microsoft.AspNetCore.Mvc;

namespace alpha.Controllers
{
    public class LoginController : Controller
    {
        [Route("login")]
        public string Index() => "Login page";
        [Route("registration")]
        public string Info() => "Registration page";
    }
}

using Microsoft.AspNetCore.Mvc;

namespace controller.Controllers
{
    public class HomeController : Controller
    {
        [Route("/")]
        public string Index() => "Home page";
    }
}

using Microsoft.AspNetCore.Mvc;

namespace controller.Controllers
{
    public class HomeController : Controller
    {
        [Route("/")]
        public string Index() => "Home page";
    }
}

Shinigami•15mo ago

Yes, sir!

wwwwOP•15mo ago

That looks very nice and very comfortable way to deal with routing

Shinigami•15mo ago

Isn't it? Builder.service.AddControllers() and app.mapcontrollers() does everything for you I've learnt this recently too, currently learning more. Answering you helped me too, haha.
