Rystem.RepositoryFramework.Api.Client 5.0.1

What is Rystem?

Services extensions

HttpClient to use your API (example)

You can add a client for a specific url

builder.Services.AddRepository<User, string>(builder =>
{
    builder
        .WithApiClient()
        .WithHttpClient("localhost:7058");
});

You may add a Polly policy to your api client for example:

var retryPolicy = HttpPolicyExtensions
  .HandleTransientHttpError()
  .Or<TimeoutRejectedException>()
  .RetryAsync(3);

builder.Services.AddRepository<User, string>(builder =>
{
    builder
        .WithApiClient()
        .WithHttpClient("localhost:7058")
            .ClientBuilder
        .AddPolicyHandler(retryPolicy);
});

and use it in DI with

IRepository<User, string> repository

Query and Command

In DI you install the services

services.AddCommand<User, string>(builder => {
    builder
        .WithApiClient()
        .WithHttpClient("localhost:7058");
});
services.AddQuery<User, string>(builder => {
    builder
        .WithApiClient()
        .WithHttpClient("localhost:7058");
});

And you may inject the objects

Please, use ICommand, IQuery and not ICommandPattern, IQueryPattern

ICommand<User, string> command
IQuery<User, string> command

With a non default key

In DI you install the services with a bool key for example.

services.AddRepository<User, bool>(builder => {
    builder
        .WithApiClient()
        .WithHttpClient("localhost:7058");
});
services.AddCommand<User, bool>(builder => {
    builder
        .WithApiClient()
        .WithHttpClient("localhost:7058");
});
services.AddQuery<User, bool>(builder => {
    builder
        .WithApiClient()
        .WithHttpClient("localhost:7058");
});

And you may inject the objects

Please, use ICommand, IQuery, IRepository and not ICommandPattern, IQueryPattern, IRepositoryPattern

IRepository<User, string> repository
ICommand<User, string> command
IQuery<User, string> command

Interceptors

You may add a custom interceptor for every request for every model

public static IServiceCollection AddApiClientInterceptor<TInterceptor>(this IServiceCollection services,
    ServiceLifetime serviceLifetime = ServiceLifetime.Scoped)
    where TInterceptor : class, IRepositoryClientInterceptor

or a specific interceptor for each model

public static IServiceCollection AddApiClientInterceptor<TInterceptor>(this IServiceCollection services,
    ServiceLifetime serviceLifetime = ServiceLifetime.Scoped)
    where TInterceptor : class, IRepositoryClientInterceptor

or for a string as default TKey

 public static RepositorySettings<T, TKey> AddApiClientSpecificInterceptor<T, TKey, TInterceptor>(
    this RepositorySettings<T, TKey> settings,
    ServiceLifetime serviceLifetime = ServiceLifetime.Scoped)
    where TInterceptor : class, IRepositoryClientInterceptor<T>
    where TKey : notnull   

Maybe you can use it to add a token as JWT o another pre-request things.

Default interceptor for Authentication with JWT

You may use the default interceptor to deal with the identity manager in .Net DI.

builder.Services.AddDefaultAuthorizationInterceptorForApiHttpClient();

This line of code inject an interceptor that works with ITokenAcquisition, injected by the framework during OpenId integration (for example AAD integration). Automatically it adds the token to each request.

You may use the default identity interceptor not on all repositories, you can specificy them with

builder.Services.AddRepository(builder => {
    builder
        .WithApiClient()
        .WithHttpClient("localhost:7058")
        .AddCustomAuthorizationInterceptorForApiHttpClient<T, TKey>();
});
