MinimalHelpers.Routing 1.0.13

Minimal APIs Routing Helpers

A library that provides Routing helpers for Minimal API projects, mainly for automatic endpoints registration.

Installation

The library is available on NuGet. Just search MinimalHelpers.Routing in the Package Manager GUI or run the following command in the Package Manager Console:

Install-Package MinimalHelpers.Routing

Usage

Automatic Route Endpoints registration

Create a class to hold your route handlers and make it implementing the IEndpointRouteHandler interface:

public class PeopleHandler : MinimalHelpers.Routing.IEndpointRouteHandler
{
    public void MapEndpoints(IEndpointRouteBuilder endpoints)
    {
        endpoints.MapGet("/api/people", GetList);
        endpoints.MapGet("/api/people/{id:guid}", Get);
        endpoints.MapPost("/api/people", Insert);
        endpoints.MapPut("/api/people/{id:guid}", Update);
        endpoints.MapDelete("/api/people/{id:guid}", Delete);
    }

    // ...
}

Call the MapEndpoints() extension method on the WebApplication object inside Program.cs before the Run() method invocation:

// using MinimalHelpers.Routing;
app.MapEndpoints();

app.Run();

By default, MapEndpoints() will scan the calling Assembly to search for classes that implement the IEndpointRouteHandler interface. If your route handlers are defined in another Assembly, you have two alternatives:

• Use the MapEndpoints() overload that takes the Assembly to scan as argument
• Use the MapEndpointsFromAssemblyContaining<T>() extension method and specify a type that is contained in the Assembly you want to scan

You can also explicitly decide what types (among the ones that implement the IRouteEndpointHandler interface) you want to actually map, passing a predicate to the MapEndpoints method:

app.MapEndpoints(type =>
{
    if (type.Name.StartsWith("Products"))
    {
        return false;
    }

    return true;
});
