About

This library contains simple implementation of the YARP configuration provider persisted in memory. It should be used for simple API Gateway scenarios, usually when designing solutions written in BFF pattern.

Sample usage

enum ServiceType
{
    HELLO,
    USERS
}

var routes = new List<RouteConfig>
{
    RouteConfigBuilder.Builder.WithId("users-all").ToService(ServiceType.USERS).WithPathMatch("/api/users", true).Build(),
    RouteConfigBuilder.Builder.WithId("hello").ToService(ServiceType.HELLO).WithPathMatch("/api/hello").Build()
} as IReadOnlyList<RouteConfig>;
var servicesUrls = new Dictionary<ServiceType, string> { 
    { ServiceType.HELLO, "https://localhost:10001" },
    { ServiceType.USERS, "https://localhost:20000" }
} as IReadOnlyDictionary<ServiceType, string>;
services.AddReverseProxy()
    .LoadFromMemory(routes, servicesUrls);

Above code will add in memory configuration provider and proxy would:

• redirect everything that matches /api/users (for example /api/users, /api/users/some/path to localhost:20000/{REQUEST_PATH})
• redirect exactly /api/hello to localhost:100001/api/hello
