SwaggerUI.OpenApi

A package to simplify adding Swagger UI to .NET 9's Microsoft.AspNetCore.OpenApi.

Usage

In your Program.cs file Add app.AddSwaggerUI() and app.MapSwaggerUI():

builder.Services.AddOpenApi();
builder.Services.AddSwaggerUI();

var app = builder.Build();

app.MapOpenApi();
app.MapSwaggerUI();

If you want to add authentication to your Swagger you can use following helper methods:

builder.Services.AddOpenApi("v1", o =>
{
    o.AddOAuth2(authorizationUrl, tokenUrl, scopes);
});

builder.Services.AddSwaggerUI("v1", o =>
{
    o.AddOAuth2(clientId, scopes);
});

There are other helper methods for Duende Identity Server AddIdentityServer() and Auth0 AddAuth0.

You can check the samples directory for complete working examples.

Features

More snippet

Adds PowerShell and CMD cURL to the request snippet by default

Styles

Easily change syntax highlighting style

builder.Services.AddSwaggerUI(o =>
{
    o.SyntaxHighlight = new SyntaxHighlightOptions
    {
        Theme = SyntaxHighlightThemeType.Arta
    };
});

Parameter validation

Displays the common validations in the parameters form by default

app.MapGet("/products",
    ([Range(0, 10000)] int id,
    [MinLength(3)][MaxLength(50)] string name,
    [RegularExpression("\\d\\d-\\d\\d")] string code) => id)

Authorization persistence

Persists authorization data by default and it would not be lost on browser close or refresh so you don't have to authenticate everytime.

Roadmap

✅ Basic UI

✅ Authentication

✅ Enable all the documents

✅ Implement all Swagger UI options

⏳ Improve test coverage
