Remora.Rest

Remora.Rest is a compact helper library for building REST API wrappers, giving you the tools you need to rapidly create robust, highly configurable wrappers of your own.

The library is somewhat opinionated, and it does target a single subset of REST API types - those whose payloads (error or otherwise) are JSON-serialized. For these use cases, however, the library is quite adept at what it does.

Quickstart

At its core, the library expects you to do two things - one, to access the REST endpoints through a configured RestHttpClient<TError>, and two, to define the entities in the API model through an interface/implementation combination.

var services = new ServiceCollection();

var clientBuilder = services
    .AddRestHttpClient<RestHttpClient<ErrorPayloadType>>();

// Perform HttpClient configuration (adding Polly policies, setting default
// request headers, etc)
clientBuilder...

// Configure API model types
services.Configure<JsonSerializerOptions>(clientBuilder.Name, options => 
{
    options.AddDataObjectConverter<IModelType, ModelType>();
});

After you've set up your client and your types, you can then inject an instance of RestHttpClient<TError> into your actual API wrapper type (the instance is transient, so you can treat it the same as any HttpClient you'd normally inject).

public class MyWrapper
{
    private readonly RestHttpClient<ErrorPayloadType> _restClient;
    
    public MyWrapper(RestHttpClient<ErrorPayloadType> restClient)
    {
        _restClient = restClient;
    }
}

More detailed documentation will hopefully be available in the future; in the meantime, check out Remora.Discord, for which this project was originally developed - it pushes all available functionality to its limits, and serves as a relatively comprehensive demonstration of what you can do with the library.
