Nabs.Launchpad.Core.Gateway

Nabs.Launchpad.Core.Gateway provides a production-ready YARP gateway setup with authentication, authorization transforms, and service discovery defaults.

Installation

dotnet add package Nabs.Launchpad.Core.Gateway

The Problem

// 1) Reverse-proxy setup duplicated between services
builder.Services.AddReverseProxy();

// 2) Missing outbound auth headers to downstream APIs
request.Headers.Add("Authorization", token); // repeated manually

// 3) Gateway options validated too late

Features

• Gateway bootstrap extensions (AddGateway, UseGateway)
• Option validation through GatewayOptionsValidator
• YARP transforms for custom headers and auth propagation
• Service defaults integration for observability/health endpoints

Usage

builder.AddGateway(options =>
{
 options.YarpOptions.HeaderName = "X-Portal";
 options.YarpOptions.HeaderValue = "launchpad";
 options.AuthorizationIssuerOptions.Issuer = "https://gateway";
});

var app = builder.Build();
app.UseGateway();

Configuration

Provide ReverseProxy route/cluster settings in configuration and configure GatewayOptions during startup.

Project Structure

• ProjectExtensions.cs - startup extension methods
• Auth/* - authentication and token-issuing helpers
• Yarp/* - request transform extensions and options
