AspNetCore Api Utilities for asp.net core that include things like an Exception Handler middleware, modelstate validation by attribute, RequireNonDefault attribute for controller models, and swagger operation filters for 400 and 500.

Install the nuget package from nuget

Either add it with the PM-Console:

    Install-Package Frogvall.AspNetCore.ApiUtilities

Or add it to csproj file ->

        <ItemGroup>
                ...
                <PackageReference Include="Frogvall.AspNetCore.ApiUtilities" Version="x.y.z" /> 
                ...
        </ItemGroup>

Edit your Startup.cs ->

    Configure(){
       ...

       app.UseApiExceptionHandler

       ...
    }

Add to controller method ->

    [ValidateModel]

Add to controller model (dto) property ->

    [RequireNonDefault]        

Add to swagger spec ->

    options.OperationFilter<ValidateModelOperationFilter>();
    options.OperationFilter<InternalServerErrorOperationFilter>();

Throw when returning non 2xx ->

    throw new ApiException(HttpStatusCode.<statuscode>, <message>);

The package is build in docker so you will need to install docker to build and publish the package. (Of course you could just build it on the machine you are running on and publish it from there. I prefer to build and publish from docker images to have a reliable environment, plus make it easier to build this on circleci).

run: docker-compose -f docker-compose-build.yml up

this will build & test the code. The testresult will be in folder ./testresults and the package in ./package

! if you clone the project on a windows machine you will have to change the file endings on the build-container.sh to LF

run: (fill in the api key):

    docker run --rm -v ${PWD}/package:/data/package schwamster/nuget-docker push /data/package/*.nupkg <your nuget api key> -Source nuget.org

this will take the package from ./package and push it to nuget.org

The project contains a working circle ci yml file. All you have to do is to configure the Nuget Api Key in the build projects environment variables on circleci (Nuget_Api_Key)
