OpenApiClient.Cli 1.0.0-preview.3

☄️ OpenAPI Client

Created with ❤ in Poland by lepo.co
OpenAPI Client is a toolkit that helps you create HTTP clients for external APIs based on their OpenAPI specifications. It simplifies the process of consuming and interacting with various web services. The project is developed and maintained by lepo.co and other community contributors.

👀 What does this repo contain?

The repository contains NuGet package source code, which uses C# code generators that can be used to generate native C# API clients from YAML or JSON files.

Gettings started

OpenApiClient is available as NuGet package on NuGet.org:
https://www.nuget.org/packages/OpenApiClient

You can add it to your project using .NET CLI:

dotnet add package OpenApiClient

, or package manager console:

NuGet\Install-Package OpenApiClient

Define an Open API file as content in your .csproj file.

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFrameworks>net8.0</TargetFrameworks>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="OpenApiClient" Version="1.0.0">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>compile; build; analyzers</IncludeAssets>
    </PackageReference>
  </ItemGroup>

  <ItemGroup>
    <OpenApiContract Include="google.youtube.api.json" />
  </ItemGroup>

</Project>

Define your partial class as open api client

/// <summary>
/// My YouTube Client.
/// </summary>
[OpenApiClient("google.youtube.api")]
public partial class YouTubeClient;

You can now use your generated client!

IYouTubeClient client = new YouTubeClient(new HttpClient());

var subscribersCount = client.SubscribersCountAsync("mychannel", CancellationToken.None);

Known limitations

Since we are using the generated internal OpenApiAttribute as a marker, conflicts may occur when we use InternalsVisibleTo.

We found the use of nullable essential, so C# 8.0 is required.
