Dependency Injection

TwelveDataSharp was built with DI in mind. You can inject the client into ASP.NET Core controllers by first creating a singleton in Startup.cs:

services.AddSingleton<TwelveDataSharp.TwelveDataClient>(new TwelveDataClient("API_KEY", new HttpClient()));

The client can now be injected into a controller:

private readonly TwelveDataClient_client;
public MyController(TwelveDataClient client)
{
    _client = client;
}

And finally used in an endpoint:

[HttpGet]
[Route("GetPrice/{symbol}")]
public async Task<ActionResult> GetPrice(string symbol)
{
    var response = await _client.GetRealTimePriceAsync(symbol);
    return Ok(response?.Price);
}
