SignalR - Notifications

[jay-cascade]

Does anybody have any information on how I can fire notifications off the back of events?

For example I can see there is an example in the codebase for: ProductCreatedEventHandler, it looks to me like this is just using logger to say something changed. But in addition to this I would like to notify my React application with the value of the entity that was created.

Sorry if this is vague! There are no docs for SignalR at present.

This is what I have tried, for an Entity called Home.

using FSH.WebApi.Domain.Common.Events;

namespace FSH.WebApi.Application.Catalog.Homes.EventHandlers;

public class HomeCreatedEventHandler : EventNotificationHandler<EntityCreatedEvent<Home>>
{
    private readonly ILogger<HomeCreatedEventHandler> _logger;
    private readonly INotificationSender _notification;
    public HomeCreatedEventHandler(ILogger<HomeCreatedEventHandler> logger, INotificationSender notificationSender) => (_logger, _notification) = (logger, notificationSender);

    public override async Task Handle(EntityCreatedEvent<Home> @event, CancellationToken cancellationToken)
    {
        _logger.LogInformation("{event} Triggered", @event.GetType().Name);
        
        await _notification.SendToAllAsync(new BasicNotification { Message = $"Home Created {@event.Entity.Id}", Label = BasicNotification.LabelType.Success }, cancellationToken);
        
        return Task.CompletedTask;
    }
}

But this seems to be wrong!

For anyone arriving here in future - refer to this: #440
