Experimental API endpoint specification and code generator for SignalR Core.
Run SigSpec.Console to see a demo spec and the generated TypeScript code.
Please let me know what you think here.
Based on NJsonSchema (see also: NSwag).

Hub:
public class ChatHub : Hub<IChatClient>
{
public Task Send(string message)
{
if (message == string.Empty)
{
return Clients.All.Welcome();
}
return Clients.All.Send(message);
}
public Task AddPerson(Person person)
{
return Task.CompletedTask;
}
public ChannelReader<Event> GetEvents()
{
var channel = Channel.CreateUnbounded<Event>();
return channel.Reader;
}
}
public class Event
{
public string Type { get; set; }
}
public class Person
{
[JsonProperty("firstName")]
public string FirstName { get; set; }
[JsonProperty("lastName")]
public string LastName { get; set; }
}
public interface IChatClient
{
Task Welcome();
Task Send(string message);
