Workleap.OpenApi.MSBuild

Validates at build time that the OpenAPI specification files extracted from the ASP.NET Core Web API being built conform to Workleap API guidelines.

Depending if the user chose the ValidateContract or GenerateContract development mode this MSBuild task will:

• Install tools: OasDiff, Spectral, SwashbuckleCLI
• Generate the OpenAPI specification file from the associated Web API
• Validate OpenAPI spec with Workleap Spectral rules
• Compare the given OpenAPI specification file with the generated one

How it works

Official Documentation

For the TLDR version:

• The entry point is ValidateOpenApiTask.ExecuteAsync() and will be executed after the referencing project is built. This is defined in ./src/Workleap.OpenApi.MSBuild/msbuild/tools/Workleap.OpenApi.MSBuild.targets as a UsingTask.TaskName
• The default value are defined in the property group on the target ValidateOpenApi in this file ./src/Workleap.OpenApi.MSBuild/msbuild/tools/Workleap.OpenApi.MSBuild.targets
• Users can select whether to validate the API with frontend or backend ruleset depending on how they configure the OpenApiServiceProfile MSBuild property (backend (default) or frontend).

Which Swashbuckle.AspNetCore.Cli version is used?

The MSBuild task uses Swashbuckle.AspNetCore.Cli to generate OpenAPI specifications. The version is resolved in the following order (highest to lowest priority):

1. Explicit configuration - Set via the OpenApiSwaggerVersion MSBuild property:

<PropertyGroup> <OpenApiSwaggerVersion>10.3.0</OpenApiSwaggerVersion> </PropertyGroup>

2. Project dependency - If your project references Swashbuckle.AspNetCore (via *.csproj or Directory.Packages.props), the same version is used.
3. Default version - Falls back to version 10.1.0 if no version is found.

How to test locally

How debug the project

Since it's a MSBuild task named ValidateOpenApi you can run it this command: msbuild /t:ValidateOpenApi. ./src/WebApiDebugger already have some preconfigured in launchSettings.json that you can run in debug.

Note: Before executing this task it will build the project.

Warming: validate your IDE is in Configuration:Debug otherwise the execution will not be done on the most recent code.
