HTTP Client Extensions

NuGet Package

Fluent HTTP client extensions for Railway Oriented Programming — handle status codes, deserialize JSON, and compose error handling with Result<T> and Maybe<T>.

Installation

dotnet add package Trellis.Http

Quick Start

using Trellis;
using Trellis.Http;

var result = await httpClient.GetAsync($"api/users/{userId}", ct)
    .HandleNotFoundAsync(Error.NotFound("User not found", userId))
    .ReadResultFromJsonAsync(UserJsonContext.Default.User, ct);

// result is Result<User> — either Success with User or Failure with NotFoundError

Status Code Handlers

var response = await httpClient.PostAsync("api/orders", content, ct);
var result = await response
    .HandleUnauthorized(Error.Unauthorized("Please login"))
    .HandleForbidden(Error.Forbidden("Admin access required"))
    .HandleConflict(Error.Conflict("Order already exists"))
    .HandleClientError(code => Error.BadRequest($"Client error: {code}"))
    .HandleServerError(code => Error.ServiceUnavailable($"Server error: {code}"))
    .ReadResultFromJsonAsync(OrderJsonContext.Default.Order, ct);
Handler HTTP Status Error Type
HandleNotFoundAsync 404 NotFoundError
HandleUnauthorizedAsync 401 UnauthorizedError
HandleForbiddenAsync 403 ForbiddenError
HandleConflictAsync 409 ConflictError
HandleClientErrorAsync 4xx Custom via factory
HandleServerErrorAsync 5xx Custom via factory
EnsureSuccessAsync Any non-success Custom via factory

ROP Pipeline Integration

var result = await httpClient.GetAsync($"api/products/{productId}", ct)
    .HandleNotFoundAsync(Error.NotFound("Product", productId))
    .ReadResultFromJsonAsync(ProductJsonContext.Default.Product, ct)
    .EnsureAsync(p => p.IsAvailable, Error.Conflict("Product unavailable"))
    .TapAsync(p => _logger.LogInformation("Retrieved: {Name}", p.Name))
    .MapAsync(p => new ProductViewModel(p));

JSON Deserialization

// Required value — null response returns error
Task<Result<T>> ReadResultFromJsonAsync<T>(jsonTypeInfo, ct)

// Optional value — null response returns Maybe.None
Task<Result<Maybe<T>>> ReadResultMaybeFromJsonAsync<T>(jsonTypeInfo, ct)
