In this tutorial, you'll learn about ASPNET Minimal Apis. We cover key concepts, practical examples, and best practices to help you understand and apply this topic effectively.
Minimal APIs in ASP.NET Core 6+ provide a streamlined way to build HTTP APIs with minimal boilerplate, perfect for Microservices and simple endpoints.
var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();
app.MapGet("/api/scan/{fileId}", async (string fileId, IScanService scan) =>
{
var result = await scan.GetResultAsync(fileId);
return result is null ? Results.NotFound() : Results.Ok(result);
});
app.MapPost("/api/scan", async (ScanRequest request, IScanService scan) =>
{
var id = await scan.StartScanAsync(request);
return Results.Created($"/api/scan/{id}", new { id });
});
app.MapGet("/api/health", () => Results.Ok(new { status = "healthy", timestamp = DateTime.UtcNow }))
.WithTags("health");
app.Run();
Minimal APIs reduce ceremony while maintaining full access to ASP.NET Core features like DI, auth, and OpenAPI.
