## Usage

### Sample application

[A demonstration of GrrrLCU with more code examples can be found here.](https://github.com/BlossomiShymae/GrrrLCU/blob/main/BlossomiShymae.GrrrLCU.Demo/Program.cs)

To run the demo:

```bash

dotnet run --project BlossomiShymae.GrrrLCU.Demo

```

### Requesting the LCU

#### General request

```csharp

var response = await Connector.SendAsync(HttpMethod.Get, "/lol-summoner/v1/current-summoner");

var me = await response.Content.ReadFromJsonAsync();

```

#### GET request

```csharp

var me = await Connector.GetFromJsonAsync("/lol-summoner/v1/current-summoner");

```

#### POST request with body

```csharp

var response = await Connector.SendAsync(HttpMethod.Post, "/player-notifications/v1/notifications", new JsonContent(playerNotificationResource));

var resource = await response.Content.ReadFromJsonAsync();

```

#### Utilities

```csharp

var processInfo = Connector.GetProcessInfo();

var riotAuthentication = new RiotAuthentication(processInfo.RemotingAuthToken);

```

### WebSockets

This library uses the `Websocket.Client` wrapper, which comes with built-in reconnection and error handling.

Create a client:

```csharp

var client = Connector.CreateLcuWebsocketClient();

```

Listen to events, disconnections, or reconnection messages:

```csharp

using System; // Include to avoid compiler errors CS1503, CS1660

              // You may or may not need this

client.EventReceived.Subscribe(msg =>

{

    Console.WriteLine(msg?.Data?.Uri);

});

client.DisconnectionHappened.Subscribe(msg => 

{

    if (msg.Exception != null) throw msg.Exception;

});

client.ReconnectionHappened.Subscribe(msg =>

{

    Console.WriteLine(msg.Type);

});

```

Use it:

```csharp

// This starts the client in a background thread. You will need an event loop

// to listen to messages.

await client.Start();

// Subscribe to every event that the League Client sends.

var message = new EventMessage(RequestType.Subscribe, EventMessage.Kinds.OnJsonApiEvent);

client.Send(message);

// We will need an event loop for the background thread to process.

// You may close at any time with Ctrl+C or similar chord.

while(true) await Task.Delay(TimeSpan.FromSeconds(1));

```
