Masterly.FluentRegex.AspNetCore

ASP.NET Core integration for Masterly.FluentRegex: register named fluent patterns once and use them as route constraints.

using Masterly.FluentRegex;

public static class Patterns
{
    public static readonly Pattern Sku = Pattern.With
        .UppercaseLetter.Repeat.Times(3).Literal("-").Digit.Repeat.Times(4);
}

builder.Services.AddFluentPatterns(registry => registry
    .Add("sku", Patterns.Sku)
    .Add("card", CommonPatterns.CreditCard().Must(Validators.Luhn, "Luhn checksum")));

app.MapGet("/items/{id:pattern(sku)}", (string id) => $"item {id}");
// GET /items/ABC-1234   -> 200
// GET /items/ABC-12345  -> 404 (the whole segment must match)
  • AddFluentPatterns registers a PatternRegistry singleton and the pattern route constraint. Calling it again adds to the same registry.
  • PatternRouteConstraint accepts a value only when the pattern matches the whole value and every rule of a ConstrainedPattern passes.
  • An unknown name in a route template, such as {id:pattern(nope)}, fails when the route table is built (on the first request) with a RouteCreationException whose inner InvalidOperationException names the pattern and lists the registered names.
  • Pattern names are case-insensitive. Targets .NET 8 and .NET 10, trimming and AOT compatible.
