Dead simple AWS SQS to Twitter serverless speaker 🔈.

Publish message 💌 to SQS (FIFO), Lambda function will handle publishing it to Twitter. Automagically. 🎉

To be honest, my plan is to automate the tweet of certain information using this queue in multiple side projects.

As usual, I'm sharing this with you folks as I was not able to find equivalent in Github / Open source projects. I hope it could be useful to someone else.

Getting started

Update variables in Makefile and tf/variables.tf according to your environment.

• type make to get started (help)

Requirements

• AWS Account
• Twitter API Keys
• Terraform

How to deploy on my AWS Account

• make all (all-in-one command)

Manual - Under the hood (for Plumbers)

1. make artifacts (create S3 bucket)
2. make package (create the zip artifact)
3. make tf-init (to prepare terraform deployment)
4. make tf-validate (optional) validate the IaC + FMT
5. make tf-plan (optional) Dry-Run
6. make tf-apply Deploy the infrastructure as code

nb: Terraform is using remote state on S3.

Setup Twitter secrets

How to get Twitter API Keys: https://developer.twitter.com/en/docs/basics/apps/guides/the-app-management-dashboard

After you've deployed the Terraform you will need to set Twitter API Keys manually to AWS Secret Manager using AWS console.

Set the following credentials in AWS Secret Manager:

1. Consumer Key
2. Consumer Key Secret
3. Access Token
4. Access Token Secret

How to publish a message

Using AWS Console

Using AWSCLI

aws sqs send-message --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyQueue --message-body "Information about the largest city in Any Region." --delay-seconds 10 --message-attributes file://send-message.json

Doc: https://docs.aws.amazon.com/cli/latest/reference/sqs/send-message.html

Using Python (boto3)

import boto3
# Create SQS client
sqs = boto3.client('sqs')
queue_url = 'SQS_QUEUE_URL'
# Send message to SQS queue
response = sqs.send_message(
    QueueUrl=queue_url,
    DelaySeconds=10,
    MessageAttributes={
        'Title': {
            'DataType': 'String',
            'StringValue': 'The Whistler'
        },
        'Author': {
            'DataType': 'String',
            'StringValue': 'John Grisham'
        },
        'WeeksOn': {
            'DataType': 'Number',
            'StringValue': '6'
        }
    },
    MessageBody=(
        'Information about current NY Times fiction bestseller for '
        'week of 12/11/2016.'
    )
)
print(response['MessageId'])
