AWS CDK Slack Messenger Example

This GitHub repository contains an AWS CDK example application that provisions AWS resources, including an SNS topic and a Lambda function, following AWS best practices. The app serves as a Slack messenger, where messages published to the SNS topic trigger the Lambda function, populating the Slack channel with the message content.

Prerequisites

Before you get started, make sure you have the following prerequisites set up:

1. AWS CLI: Ensure you have the AWS Command Line Interface installed and configured with the necessary credentials.

2. AWS CDK: Install the AWS Cloud Development Kit (CDK) using the following command:

   npm install -g aws-cdk
   

3. Slack Webhook: You will need to configure a Slack webhook before deploying the application. Set up the webhook in the lib/zdf_aws-notifications-stack.ts file.

Getting Started

Follow the steps below to deploy and run the Slack Messenger application:

1. Clone the repository:

   git clone https://github.com/your-username/aws-cdk-slack-messenger.git
   cd aws-cdk-slack-messenger
   

2. Install dependencies:

   npm install
   

3. Configure the Slack webhook:

   Open the lib/zdf_aws-notifications-stack.ts file and replace <SLACK_WEBHOOK_URL> with the actual Slack webhook URL provided by your Slack workspace.

4. Deploy the application:

   cdk deploy
   

   The CDK will deploy the necessary AWS resources based on the configuration specified in the lib/zdf_aws-notifications-stack.ts file.

5. Test the Slack Messenger:

   Publish a message to the SNS topic created by the CDK stack. This message will trigger the Lambda function, and the message content will be sent to the Slack channel using the configured webhook.

Clean Up

To avoid incurring unnecessary AWS costs, you can remove the deployed resources after testing the Slack Messenger:

cdk destroy

This will delete all the AWS resources provisioned by the CDK stack.
