Refitter.MSBuild 1.5.0-preview.65

MSBuild Tasks for Refitter

Refitter is available as custom MSBuild tasks that uses the Refitter.Core library for generating a REST API Client using the Refit library. Refitter can generate the Refit interface from OpenAPI specifications. Refitter could format the generated Refit interface to be managed by Apizr (v6+) and generate some registration helpers too.

}

• openApiPath - points to the OpenAPI Specifications file. This can be the path to a file stored on disk, relative to the .refitter file. This can also be a URL to a remote file that will be downloaded over HTTP/HTTPS
• namespace - the namespace used in the generated code. If not specified, this defaults to GeneratedCode
• naming.useOpenApiTitle - a boolean indicating whether the OpenApi title should be used. Default is true
• naming.interfaceName - the name of the generated interface. The generated code will automatically prefix this with I so if this set to MyApiClient then the generated interface is called IMyApiClient. Default is ApiClient
• generateContracts - a boolean indicating whether contracts should be generated. A use case for this is several API clients use the same contracts. Default is true
• generateXmlDocCodeComments - a boolean indicating whether XML doc comments should be generated. Default is true
• addAutoGeneratedHeader - a boolean indicating whether XML doc comments should be generated. Default is true
• addAcceptHeaders - a boolean indicating whether to add accept headers [Headers("Accept: application/json")]. Default is true
• returnIApiResponse - a boolean indicating whether to return IApiResponse<T> objects. Default is false
• responseTypeOverride - a dictionary with operation ids (as specified in the OpenAPI document) and a particular return type to use. The types are wrapped in a task, but otherwise unmodified (so make sure to specify or import their namespaces). Default is {}
• generateOperationHeaders - a boolean indicating whether to use operation headers in the generated methods. Default is true
• typeAccessibility - the generated type accessibility. Possible values are Public and Internal. Default is Public
• useCancellationTokens - Use cancellation tokens in the generated methods. Default is false
• useIsoDateFormat - Set to true to explicitly format date query string parameters in ISO 8601 standard date format using delimiters (for example: 2023-06-15). Default is false
• multipleInterfaces - Set to ByEndpoint to generate an interface for each endpoint, or ByTag to group Endpoints by their Tag (like SwaggerUI groups them).
• outputFolder - a string describing a relative path to a desired output folder. Default is ./Generated
• outputFilename - Output filename. Default is Output.cs when used from the CLI tool, otherwise its the .refitter filename. So Petstore.refitter becomes Petstore.cs.
• additionalNamespaces - A collection of additional namespaces to include in the generated file. A use case for this is when you want to reuse contracts from a different namespace than the generated code. Default is empty
• includeTags - A collection of tags to use a filter for including endpoints that contain this tag.
• includePathMatches - A collection of regular expressions used to filter paths.
• generateDeprecatedOperations - a boolean indicating whether deprecated operations should be generated or skipped. Default is true
• operationNameTemplate - Generate operation names using pattern. This must contain the string {operationName}. An example usage of this could be {operationName}Async to suffix all method names with Async. When using "multipleIinterfaces": "ByEndpoint", This is name of the Execute() method in the interface
• optionalParameters - Generate non-required parameters as nullable optional parameters
• useDynamicQuerystringParameters: Set to true to wrap multiple query parameters into a single complex one. Default is false (no wrapping).
• dependencyInjectionSettings - Setting this will generated extension methods to IServiceCollection for configuring Refit clients. See https://github.com/reactiveui/refit?tab=readme-ov-file#dynamic-querystring-parameters for more information.
  • baseUrl - Used as the HttpClient base address. Leave this blank to manually set the base URL
  • httpMessageHandlers - A collection of HttpMessageHandler that is added to the HttpClient pipeline
  • transientErrorHandler - This is the transient error handler to use. Possible values are None, Polly, and HttpResilience. Default is None
  • maxRetryCount - This is the max retry count used in the Polly retry policy. Default is 6
  • firstBackoffRetryInSeconds - This is the duration of the initial retry backoff. Default is 1 second
• apizrSettings - Setting this will format Refit interface to be managed by Apizr. See https://www.apizr.net for more information
  • withRequestOptions - Tells if the Refit interface methods should have a final IApizrRequestOptions options parameter
  • withRegistrationHelper - Tells if Refitter should generate Apizr registration helpers (extended with dependencyInjectionSettings set, otherwise static)
  • withCacheProvider - Set the cache provider to be used
  • withPriority - Tells if Apizr should handle request priority
  • withMediation - Tells if Apizr should handle request mediation (extended only)
  • withOptionalMediation - Tells if Apizr should handle optional request mediation (extended only)
  • withMappingProvider - Set the mapping provider to be used
  • withFileTransfer - Tells if Apizr should handle file transfer
• codeGeneratorSettings - Setting this allows customization of the NSwag generated types and contracts
  • requiredPropertiesMustBeDefined - Default is true,
  • generateDataAnnotations - Default is true,
  • anyType - Default is object,
  • dateType - Default is System.DateTimeOffset,
  • dateTimeType - Default is System.DateTimeOffset,

  • timeSpanType - Default is System.TimeSpan,
