# SQSDemo

An example of an AWS SQS producer and consumer application written in Swift.

![producer and consumer](hero.png)

## Producer

The producer cli takes arguments from the command line to send messages:

```swift

import SotoSQS

let arguments = ProcessInfo.processInfo.arguments

guard arguments.count > 1 else {

    print("Nothing to send")

    exit(0)

}

let client = AWSClient(httpClientProvider: .createNew)

defer { try? client.syncShutdown() }

let sqs = SQS(client: client, region: .uswest2)

let queue = "https://sqs.us-west-2.amazonaws.com//sqs-swift-demo"

for message in arguments.dropFirst() {

    let input = SQS.SendMessageRequest(messageBody: message, queueUrl: queue)

    let result = try sqs.sendMessage(input).wait()

    print(result.messageId ?? "[No id]")

}

```

## Consumer

The consumer cli loops forever, waiting for messages to arrive.

```swift

import SotoSQS

let client = AWSClient(httpClientProvider: .createNew)

defer { try? client.syncShutdown() }

let sqs = SQS(client: client, region: .uswest2)

let queue = "https://sqs.us-west-2.amazonaws.com//sqs-swift-demo"

// Poll for messages, waiting for up to 10 seconds

let request = SQS.ReceiveMessageRequest(queueUrl: queue, waitTimeSeconds: 10)

// Fetch messages forever, until interrupted or terminated

while true {

    print("Polling for messages...")

    let result = try sqs.receiveMessage(request).wait()

    for message in result.messages ?? [] {

        print("Message Id:", message.messageId ?? "[no id]")

        print("Content:", message.body ?? "[no message]")

        if let handle = message.receiptHandle {

            let deleteRequest = SQS.DeleteMessageRequest(queueUrl: queue, receiptHandle: handle)

            _ = try sqs.deleteMessage(deleteRequest).wait()

        }

    }

}

```
