API Setup

Configure the affolterNET.Web.Api service registration and middleware pipeline.

For complete reference, see Library Guide.

Quick Start

// Program.cs
var builder = WebApplication.CreateBuilder(args);

// Step 1: Register services
var options = builder.Services.AddApiServices(
    builder.Environment.IsDevelopment(),
    builder.Configuration,
    opts => {
        opts.EnableSecurityHeaders = true;
        opts.ConfigureApi = api => {
            api.AuthMode = AuthenticationMode.Authorize;
        };
    });

var app = builder.Build();

// Step 2: Configure middleware
app.ConfigureApiApp(options);

app.Run();

Middleware Pipeline

The ConfigureApiApp configures middleware in this order:

1. Security Headers Middleware
2. Swagger/​OpenAPI
3. Routing
4. Custom Middleware (after routing hook)
5. CORS
6. Authentication & Authorization + RPT Middleware
7. Custom Middleware (before endpoints hook)
8. Endpoint Mapping (with Health Checks)

Common Patterns

Development vs Production

var options = builder.Services.AddApiServices(
    builder.Environment.IsDevelopment(),  // isDev flag
    builder.Configuration,
    opts => {
        // Development-specific config happens automatically
        // based on isDev flag
    });

Adding Custom Middleware

var options = builder.Services.AddApiServices(isDev, config, opts => {
    opts.ConfigureAfterRoutingCustomMiddleware = app => {
        app.UseMiddleware<RequestLoggingMiddleware>();
    };
    opts.ConfigureBeforeEndpointsCustomMiddleware = app => {
        app.UseMiddleware<TenantMiddleware>();
    };
});
