The ultimate goal of this library is to eliminate as much boilerplate as possible by offering out-of-the-box features such as sorting, filtering and pagination. You just need to focus on defining the resources and implementing your custom business logic. This library has been designed around dependency injection, making extensibility incredibly easy.

public class ArticlesController : JsonApiController<Article>
    public ArticlesController(IJsonApiOptions options, IResourceService<Article> resourceService,
        ILoggerFactory loggerFactory)
        : base(options, resourceService, loggerFactory)


public class Startup
    public IServiceProvider ConfigureServices(IServiceCollection services)

    public void Configure(IApplicationBuilder app)
        app.UseEndpoints(endpoints => endpoints.MapControllers());


Restore all NuGet packages with:

dotnet restore


Running tests locally requires access to a PostgreSQL database. If you have docker installed, this can be propped up via:

docker run --rm --name jsonapi-dotnet-core-testing  -e POSTGRES_DB=JsonApiDotNetCoreExample -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres -p 5432:5432 postgres:12.0

And then to run the tests:

dotnet test
