# .NET library to easily subscribe and listen PostgreSQL Database real time notifications

![build](https://github.com/psosnicki/pgnotify-net/actions/workflows/dotnet.yml/badge.svg)

## Install

```

PM> Install-Package PgNotifyNet -Version 1.0.1-beta

```

## Example

[Blazor SignalR Postgresql PgNotifyNet sample application](samples/PgNotifyNet.Sample/README.md)

## Sample Code

Register in container:

```

ConfigureServices(IServicesCollection servicesCollection)

{

        ...

        services.AddPgNotifyNet(connectionString,

                o => o.Trigger (t => t.OnTable("categories").After(Change.Update, Change.Delete))

                      .Trigger (t => t.OnTable("users").After(Change.Insert))

        ...

);

```

Implement ```IHandleNotification``` and handle notification:

```

    public  class FooNotificationHandler : IHandleNotification

    {

        public async Task OnDataChanged(Category oldData,Category newData, Change change)

        {

            //handle data change

        }

    }

```

or subscribe to PgNotificationService ```OnDataChange``` event 

```

    public FooController(IPgNotificationService notificationService)

    {

        notificationService.OnDataChange += (object? sender, OnDataChangeEventArgs e) => { 

            //handle notification

        };

    }

```
