Inject a reusable client

To maintain optimal performance, reuse the client instance for every request. To do this, inject the SearchClient as singleton in the service provider. Open the Startup.cs file and add the following line in the ConfigureServices method.
C#
public void ConfigureServices(IServiceCollection services)
{
    // ...
    services.AddSingleton<ISearchClient, SearchClient>();
    services.AddSingleton<ISearchClient>(new SearchClient("ALGOLIA_APPLICATION_ID", "ALGOLIA_API_KEY"));
    // ...
}
You can reuse the same SearchClient for multiple indices, as SearchClient is thread-safe.
If you are using other clients such as the AnalyticsClient or InsightsClient you should also add them as singletons in the service provider.

​
Reusable clients in your controllers

To reuse the SearchClient instance in your controllers, add the following lines:
C#
public class HomeController : Controller
{
    private readonly ISearchClient _searchClient;

    public HomeController(ISearchClient searchClient)
    {
        _searchClient = searchClient;
    }
}
