SlackIntegration can be used for sending messages to the Slack using the webhook integration.

Installation:

Available as a NuGet package.

dotnet add package Warden.Integrations.Slack

Configuration:

• WithDefaultMessage() - default message text.
• WithDefaultChannel() - default name of channel to which the message will be sent.
• WithDefaultUsername() - default username that will send the message.
• WithTimeout() - timeout of the HTTP request to the Slack API.
• FailFast() - flag determining whether an exception should be thrown if SendMessageAsync() returns invalid reponse (false by default).
• WithSlackServiceProvider() - custom provider for the ISlackService.

SlackIntegration can be configured by using the SlackIntegrationConfiguration class or via the lambda expression passed to a specialized constructor.

Initialization:

In order to register and resolve SlackIntegration make use of the available extension methods while configuring the Warden:

var wardenConfiguration = WardenConfiguration
    .Create()
    .IntegrateWithSlack("https://hooks.slack.com/services/XXX/YYY/ZZZ", cfg =>
    {
        cfg.WithDefaultMessage("Monitoring status")
           .WithDefaultUsername("Warden");
    })
    .SetGlobalWatcherHooks((hooks, integrations) =>
    {
        hooks.OnStart(check => GlobalHookOnStart(check))
             .OnFailure(result => integrations.Slack().SendMessageAsync("Monitoring errors have occured."))
    })
    //Configure watchers, hooks etc..

Custom interfaces:

public interface ISlackService
{
    Task SendMessageAsync(string message, string channel = null, string username = null, 
            TimeSpan? timeout = null, bool failFast = false);
}

ISlackService is responsible for sending the message using Slack Webhook. It can be configured via the WithSlackServiceProvider() method. By default, it is based on the HttpClient library.
