Scalar.Kiota.Extension 1.0.0-preview.6

Scalar.Kiota.Extension

Automates Kiota SDK generation and integrates it with Scalar API documentation for ASP.NET Core minimal APIs with native AOT support.

Installation

dotnet add package Scalar.Kiota.Extension --prerelease

Quick Start

using Scalar.Kiota.Extension;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddScalarWithKiota();

var app = builder.Build();

app.MapScalarWithKiota("/api");

await app.RunAsync();

Configuration

builder.Services.AddScalarWithKiota(options =>
{
    options.WithTitle("My API")                    // Default: "{ApplicationName} API"
           .WithTheme(ScalarTheme.Saturn)          // Default: Saturn
           .WithSdkName("MyApiClient")             // Default: "ApiClient"
           .WithLanguages("TypeScript", "CSharp")  // Default: ["TypeScript"]
           .WithOutputPath("./custom-output")      // Default: "wwwroot/.scalar-kiota"
           .WithOpenDocsOnStartup();               // Default: false
           
    options.BundleTypeScript = true;               // Default: true
    options.DocumentationPath = "/docs";           // Default: null (uses pattern)
});

How It Works

1. Downloads OpenAPI spec from /openapi/v1.json
2. Generates SDKs using Kiota CLI (auto-installed if missing)
3. For TypeScript: creates package.json, installs dependencies, bundles with esbuild
4. Creates config.js that exposes the SDK to Scalar's "Try It" feature
5. Only regenerates when OpenAPI spec changes (SHA256 hash-based caching)

Requirements

• Download .NET 10.0 Preview
• Install Node.js (for TypeScript bundling)
