Scalar.AspNetCore 2.1.6

Scalar .NET API Reference Integration

This .NET package Scalar.AspNetCore provides an easy way to render beautiful API references based on OpenAPI/Swagger documents.

Made possible by the wonderful work of @captainsafia on building the integration and docs written for the Scalar & .NET integration. Thanks to @xC0dex for making it awesome.

Features

• Stunning API Reference
• Compatible with .NET 8 and above
• Independent of OpenAPI document generators
• Fully AOT (Ahead-of-Time) compatible

Migration Guide

If you are upgrading from 1.x.x to 2.x.x, please refer to the migration guide.

Usage

1. Install the package

dotnet add package Scalar.AspNetCore --version 2.1.*

[!NOTE] We release new versions frequently to bring you the latest features and bug fixes. To reduce the noise in your project file, we recommend using a wildcard for the patch version, e.g., 2.1.*.

2. Add the using directive

using Scalar.AspNetCore;

3. Configure your application

Add the following to Program.cs based on your OpenAPI generator:

For Microsoft.AspNetCore.OpenApi:

builder.Services.AddOpenApi();

if (app.Environment.IsDevelopment())
{
    app.MapOpenApi();
    app.MapScalarApiReference();
}

For Swashbuckle:

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

if (app.Environment.IsDevelopment())
{
    app.UseSwagger(options =>
    {
        options.RouteTemplate = "/openapi/{documentName}.json";
    });
    app.MapScalarApiReference();
}

For NSwag:

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddOpenApiDocument();

if (app.Environment.IsDevelopment())
{
    app.UseOpenApi(options =>
    {
        options.Path = "/openapi/{documentName}.json";
    });
    app.MapScalarApiReference();
}

That's it! 🎉 You can now access the Scalar API Reference at /scalar. By default, the API Reference uses the v1 document. You can add documents by calling the AddDocument method. Alternatively, you can navigate to /scalar/{documentName} (e.g., /scalar/v1) to view the API Reference for a specific document. Please check out the dotnet integration documentation for more details.

Configuration

For detailed configuration options, refer to the integration documentation. This documentation focuses on the features provided by the package.

For more realistic examples and advanced usage scenarios, such as authentication, API versioning, and handling multiple documents, check out our extended examples documentation. This documentation is also useful if you need more context on what Scalar.AspNetCore is for.
