AutoSDK 0.24.1-dev.9

AutoSDK

Allows you to partially (for example, only models) or completely generate a native (without dependencies) C# client sdk according to the OpenAPI specification.
Inspired by NSwag ❤️.

🔥Features🔥

• Uses Incremental Source Generators for efficient generation and caching.
• Detects your TargetFramework and generates optimal code for it (including net6.0/net7.0/net8.0 improvements)
• Supports .Net Framework/.Net Standard
• Does not contain dependencies for modern versions of dotnet
• Only System.Text.Json dependency for .Net Framework/.Net Standard
• Any generated methods provide the ability to pass a CancellationToken
• Allows partial generation (models only) or end points filtering
• Available under MIT license for general users and most organizations
• Uses https://github.com/microsoft/OpenAPI.NET for parsing OpenAPI specification
• Supports nullable enable/trimming/native AOT compilation/CLS compliance
• Tested on GitHub 220k lines OpenAPI specification
• Supports OneOf/AnyOf/AllOf/Not schemas
• Supports Enums for System.Text.Json
• Efficient O(n) implementation, fully suitable for large/super large OpenAPI specifications
• Used in 10+ real SDKs and adapted to solve various problems

🚀Quick start🚀

CLI (Recommended)

You can use the CLI to generate the code.

dotnet tool install --global autosdk.cli --prerelease
rm -rf Generated
autosdk generate openapi.yaml \
    --namespace Namespace \
    --clientClassName YourApi \
    --targetFramework net8.0 \
    --output Generated

It will generate the code in the "Generated" subdirectory.
It also will include polyfills for .Net Framework/.Net Standard TargetFrameworks.

Source generator

• Install the package

dotnet add package AutoSDK

• Add the following optional settings to your csproj file to customize generation. You can check all settings here:

<ItemGroup Label="AutoSDK">
    <AdditionalFiles Include="$(MSBuildThisFileDirectory)../../../docs/openapi.yaml" />
</ItemGroup>


<PropertyGroup Label="AutoSDK">
    <AutoSDK_Namespace>Ollama</AutoSDK_Namespace>
    <AutoSDK_ClassName>OllamaApi</AutoSDK_ClassName>

    
    <AutoSDK_GenerateSdk>false</AutoSDK_GenerateSdk>
    <AutoSDK_GenerateModels>true</AutoSDK_GenerateModels>
    <AutoSDK_GenerateMethods>true</AutoSDK_GenerateMethods>
    <AutoSDK_GenerateConstructors>true</AutoSDK_GenerateConstructors>
    <AutoSDK_IncludeOperationIds>getPet;deletePet</AutoSDK_IncludeOperationIds>
    <AutoSDK_ExcludeOperationIds>getPet;deletePet</AutoSDK_ExcludeOperationIds>
    <AutoSDK_IncludeModels>Pet;Model</AutoSDK_IncludeModels>
    <AutoSDK_ExcludeModels>Pet;Model</AutoSDK_ExcludeModels>
</PropertyGroup>

• It's all! Now you can build your project and use the generated code. You also can use IDE to see the generated code in any moment, this is a example for Rider:
  

Trimming support

CLI

CLI generates Trimming/NativeAOT compatible code by default.

Source generator

Since there are two source generators involved, we will have to create a second project so that the generator for the JsonSerializerContext will “see” our models

• Create new project for your models. And disable methods/constructors generation:

<PropertyGroup Label="AutoSDK">
    <AutoSDK_GenerateSdk>false</AutoSDK_GenerateSdk>
    <AutoSDK_GenerateModels>true</AutoSDK_GenerateModels>
    <AutoSDK_GenerateJsonSerializerContextTypes>true</AutoSDK_GenerateJsonSerializerContextTypes>
</PropertyGroup>

• Reference this project in your main project.
• Add SourceGenerationContext.cs file to your main project with the following content:

using System.Text.Json.Serialization;

namespace Namespace;

[JsonSourceGenerationOptions(DefaultIgnoreCondition = JsonIgnoreCondition.WhenWritingNull)]
[JsonSerializable(typeof(AutoSDKTrimmableSupport))]
internal sealed partial class SourceGenerationContext : JsonSerializerContext;

• Add the following settings to your main csproj file:

<PropertyGroup Label="AutoSDK">
    <AutoSDK_GenerateSdk>false</AutoSDK_GenerateSdk>
    <AutoSDK_GenerateMethods>true</AutoSDK_GenerateMethods>
    <AutoSDK_GenerateConstructors>true</AutoSDK_GenerateConstructors>
    <AutoSDK_JsonSerializerContext>Namespace.SourceGenerationContext</AutoSDK_JsonSerializerContext>
</PropertyGroup>

• Add these settings to your new and main csproj file to enable trimming(or use Directory.Build.props file):

<PropertyGroup Label="Trimmable" Condition="$([MSBuild]::IsTargetFrameworkCompatible('$(TargetFramework)', 'net6.0'))">
    <IsAotCompatible>true</IsAotCompatible>
    <EnableTrimAnalyzer>true</EnableTrimAnalyzer>
    <IsTrimmable>true</IsTrimmable>
    <SuppressTrimAnalysisWarnings>false</SuppressTrimAnalysisWarnings>
    <TrimmerSingleWarn>false</TrimmerSingleWarn>
</PropertyGroup>

• It's all! Now you can build your project and use the generated code with full trimming/nativeAOT support.
