slackronym

Simple AWS Lambda function for looking up acronyms with a Slack slash command.

Getting started

To get this Slack integration up and running, you will need to:

1. Fork this repository
2. Add GitHub Actions secrets to your new repository to allow deployment to your AWS environment. See below for more details.
3. Update acronyms.csv with your organization's acronyms
4. Deploy the app to AWS using the included GitHub Actions workflow. There should be a Function URL available in the slackronym Lambda function.
5. Create and install a Slack app that uses a "slash command" to send requests to that Function URL

Use the SAM CLI to build and test locally

Build the application with the sam build command.

slackronym$ sam build

Run functions locally and invoke them with the sam local invoke command.

slackronym$ sam local invoke SlackronymFunction --event events/event.json

Tests

Tests are defined in the tests folder in this project.

slackronym$ pytest

Deploy the sample application using GitHub Actions

• Create a user in AWS IAM. Save the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY in GitHub Actions Secrets.
• Attach an IAM policy to the user that is similar to the JSON below (or ideally more tightly scoped):
