Minimal APIs Helpers
A collection of helpers libraries for Minimal API projects.
MinimalHelpers.Routing
A library that provides Routing helpers for Minimal API projects for automatic endpoints registration using Reflection.
Installation
The library is available on NuGet. Just search for MinimalHelpers.Routing in the Package Manager GUI or run the following command in the .NET CLI:
dotnet add package MinimalHelpers.Routing
Usage
Create a class to hold your route handlers registration and make it implementing the IEndpointRouteHandlerBuilder
interface:
.NET 6.0
public class PeopleHandler : MinimalHelpers.Routing.IEndpointRouteHandlerBuilder
{
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);
}
// ...
}
.NET 7.0 or higher
public class PeopleHandler : MinimalHelpers.Routing.IEndpointRouteHandlerBuilder
{
public static 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);
}
// ...
}
Note Starting from .NET 7.0, the
IEndpointRouteHandlerBuilder
interface exposes theMapEndpoints
method as static abstract, so it can be called without creating an instance of the handler.
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 IEndpointRouteHandlerBuilder
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 IRouteEndpointHandlerBuilder
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;
});
Note These methods rely on Reflection to scan the Assembly and find the classes that implement the
IEndpointRouteHandlerBuilder
interface. This can have a performance impact, especially in large projects. If you have performance issues, consider using the explicit registration method. Moreover, this solution is incompatibile with Native AOT.
If you're working with .NET 7.0 or higher, the reccommended approach is to use the MinimalHelpers.Routing.Analyzers package, that provides a Source Generator for endpoints registration, as described later.
MinimalHelpers.Routing.Analyzers (.NET 7.0 or higher)
A library that provides a Source Generator for automatic endpoints registration in Minimal API projects.
Installation
The library is available on NuGet. Just search for MinimalHelpers.Routing in the Package Manager GUI or run the following command in the .NET CLI:
dotnet add package MinimalHelpers.Routing.Analyzers
Usage
Create a class to hold your route handlers registration and make it implementing the IEndpointRouteHandlerBuilder
interface:
public class PeopleHandler : IEndpointRouteHandlerBuilder
{
public static 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);
}
// ...
}
Note You only need to use the MinimalHelpers.Routing.Analyzers package. With this Source Generator, the
IEndpointRouteHandlerBuilder
interface is auto-generated.
Call the MapEndpoints()
extension method on the WebApplication object inside Program.cs before the Run()
method invocation:
app.MapEndpoints();
app.Run();
Note The
MapEndpoints
method is generated by the Source Generator.
MinimalHelpers.OpenApi
A library that provides OpenApi helpers for Minimal API projects.
Installation
The library is available on NuGet. Just search for MinimalHelpers.OpenApi in the Package Manager GUI or run the following command in the .NET CLI:
dotnet add package MinimalHelpers.OpenApi
Usage
Extension methods for OpenApi
This library provides some extensions methods that simplify the OpenAPI configuration in Minimal API projects. For example, it is possible to customize the description of a response using its status code:
endpoints.MapPost("login", LoginAsync)
.AllowAnonymous()
.WithValidation<LoginRequest>()
.Produces<LoginResponse>(StatusCodes.Status200OK)
.Produces<LoginResponse>(StatusCodes.Status206PartialContent)
.Produces(StatusCodes.Status403Forbidden)
.ProducesValidationProblem()
.WithOpenApi(operation =>
{
operation.Summary = "Performs the login of a user";
operation.Response(StatusCodes.Status200OK).Description = "Login successful";
operation.Response(StatusCodes.Status206PartialContent).Description = "The user is logged in, but the password has expired and must be changed";
operation.Response(StatusCodes.Status400BadRequest).Description = "Incorrect username and/or password";
operation.Response(StatusCodes.Status403Forbidden).Description = "The user was blocked due to too many failed logins";
return operation;
});
MinimalHelpers.Validation
A library that provides an Endpoint filter for Minimal API projects to perform validation with Data Annotations, using the <a href="https://github.com/DamianEdwards/MiniValidation">MiniValidation</a> library.
Installation
The library is available on NuGet. Just search for MinimalHelpers.Validation in the Package Manager GUI or run the following command in the .NET CLI:
dotnet add package MinimalHelpers.Validation
Usage
Decorates a class with attributes to define the validation rules:
using System.ComponentModel.DataAnnotations;
public class Person
{
[Required]
[MaxLength(20)]
public string? FirstName { get; set; }
[Required]
[MaxLength(20)]
public string? LastName { get; set; }
[MaxLength(50)]
public string? City { get; set; }
}
Add the WithValidation<T>()
extension method to enable the validation filter:
using MinimalHelpers.Validation;
app.MapPost("/api/people", (Person person) =>
{
// ...
})
.WithValidation<Person>();
If the validation fails, the response will be a 400 Bad Request
with a ValidationProblemDetails
object containing the validation errors, for example:
{
"type": "https://tools.ietf.org/html/rfc9110#section-15.5.1",
"title": "One or more validation errors occurred",
"status": 400,
"instance": "/api/people",
"traceId": "00-009c0162ba678cae2ee391815dbbb59d-0a3a5b0c16d053e6-00",
"errors": {
"FirstName": [
"The field FirstName must be a string or array type with a maximum length of '20'."
],
"LastName": [
"The LastName field is required."
]
}
}
If you want to customize validation, you can use the ConfigureValidation
extension method:
using MinimalHelpers.Validation;
builder.Services.ConfigureValidation(options =>
{
// If you want to get errors as a list instead of a dictionary.
options.ErrorResponseFormat = ErrorResponseFormat.List;
// The default is "One or more validation errors occurred"
options.ValidationErrorTitleMessageFactory =
(context, errors) => $"There was {errors.Values.Sum(v => v.Length)} error(s)";
});
You can use the ValidationErrorTitleMessageFactory
, for example, if you want to localized the title
property of the response using a RESX file.
MinimalHelpers.FluentValidation
A library that provides an Endpoint filter for Minimal API projects to perform validation using <a href="https://fluentvalidation.net">FluentValidation</a>.
Installation
The library is available on NuGet. Just search for MinimalHelpers.FluentValidation in the Package Manager GUI or run the following command in the .NET CLI:
dotnet add package MinimalHelpers.FluentValidation
Usage
Create a class that extends AbstractValidator<T> and define the validation rules:
using FluentValidation;
public record class Product(string Name, string Description, double UnitPrice);
public class ProductValidator : AbstractValidator<Product>
{
public ProductValidator()
{
RuleFor(p => p.Name).NotEmpty().MaximumLength(50).EmailAddress();
RuleFor(p => p.Description).MaximumLength(500);
RuleFor(p => p.UnitPrice).GreaterThan(0);
}
}
Register validators in the Service Collection:
using FluentValidation;
// Assuming the validators are in the same assembly as the Program class
builder.Services.AddValidatorsFromAssemblyContaining<Program>();
Add the WithValidation<T>()
extension method to enable the validation filter:
using MinimalHelpers.FluentValidation;
app.MapPost("/api/products", (Product product) =>
{
// ...
})
.WithValidation<Product>();
If the validation fails, the response will be a 400 Bad Request
with a ValidationProblemDetails
object containing the validation errors, for example:
{
"type": "https://tools.ietf.org/html/rfc9110#section-15.5.1",
"title": "One or more validation errors occurred",
"status": 400,
"instance": "/api/products",
"traceId": "00-f4ced0ae470424dd04cbcebe5f232dc5-bbdcc59f310ebfb8-00",
"errors": {
"Name": [
"'Name' cannot be empty."
],
"UnitPrice": [
"'Unit Price' must be grater than '0'."
]
}
}
If you want to customize validation, you can use the ConfigureValidation
extension method:
using MinimalHelpers.Validation;
builder.Services.ConfigureValidation(options =>
{
// If you want to get errors as a list instead of a dictionary.
options.ErrorResponseFormat = ErrorResponseFormat.List;
// The default is "One or more validation errors occurred"
options.ValidationErrorTitleMessageFactory =
(context, errors) => $"There was {errors.Values.Sum(v => v.Length)} error(s)";
});
You can use the ValidationErrorTitleMessageFactory
, for example, if you want to localized the title
property of the response using a RESX file.
