Swift 3.2 Platform Docs @SvenTiigi

PerfectSlackAPIClient is an API Client to access the Slack API from your Perfect Server Side Swift application. It is build on top of PerfectAPIClient, a network abstraction layer to perform network requests from your Perfect Server Side Swift application

Installation

To integrate using Apple's Swift Package Manager, add the following as a dependency to your Package.swift:

.package(url: "https://github.com/SvenTiigi/PerfectSlackAPIClient.git", from: "1.0.0")

Here's an example PackageDescription:

// swift-tools-version:4.0

import PackageDescription

let package = Package(
    name: "MyPackage",
    products: [
        .library(
            name: "MyPackage",
            targets: ["MyPackage"]
        )
    ],
    dependencies: [
        .package(url: "https://github.com/SvenTiigi/PerfectSlackAPIClient.git", from: "1.0.0")
    ],
    targets: [
        .target(
            name: "MyPackage",
            dependencies: ["PerfectSlackAPIClient"]
        ),
        .testTarget(
            name: "MyPackageTests",
            dependencies: ["MyPackage", "PerfectSlackAPIClient"]
        )
    ]
)

Setup

In order to send a message to your Slack-Channel, you have to generate a Webhook URL for your Slack-Workspace. Check out the Slack API Hello world example. After you successfully generated a Slack Webhook URL you can configure the SlackAPIClient.

// Configure the Webhook URL
SlackAPIClient.Configuration.webhookURL = "YOUR_WEBHOOK_URL"

It is recommend to set the Webhook URL in your initialization code just before you start your PerfectHTTPServer.

Usage

The following example demonstrates how to send a SlackMessage.

import PerfectAPIClient
import PerfectSlackAPIClient

// Initialize SlackMessage
var message = SlackMessage()
message.text = "Hello Developer".toMarkdown(format: .code)

// Initialize SlackAttachment
var attachment = SlackAttachment()
attachment.title = "Mindblown 🤯"
attachment.imageURL = "https://media.giphy.com/media/Um3ljJl8jrnHy/giphy.gif"

// Add the attachment to the message
message.attachments = [attachment]

// Send SlackMessage
SlackAPIClient.send(message).request { (result: APIClientResult<APIClientResponse>) in
    result.analysis(success: { (response: APIClientResponse) in
        // Check out your Slack-Channel 😎
        print(response.payload) // "ok"
    }, failure: { (error: APIClientError) in
        // SlackMessage could not be sent 😱
        // Perform error.analysis(....) to get more information
    })
}

Fore more details on APIClientResult, APIClientResponse and error handling check out PerfectAPIClient.

SlackMessage

The SlackMessage offers two important features which will be explained in the upcoming sections.

Message Builder Preview

You can generate a Slack Message Builder URL from your SlackMessage to get a brief look of how your message will be presented in your Slack-Channel.

// Initialize SlackMessage
let message = SlackMessage(text: "Posted via PerfectSlackAPIClient")

// Print Slack Message Builder Preview URL
print(message.messageBuilderPreviewURL)

This example will generate the following url

https://api.slack.com/docs/messages/builder?msg=%7B%22text%22:%22Posted%20via%20PerfectSlackAPIClient%22%7D

Send

As an alternative way of sendind a SlackMessage, the object itself has a convienence function send to just send and forget or supply success and failure closure.

// Initialize SlackMessage
let message = SlackMessage(text: "Foo Bar")

// Send and forget
message.send()

// Success and failure closure
message.send(success: { (response: APIClientResponse) in
    // Success
}, failure: { (error: APIClientError) in
    // Failure
})
