Fauci Bot

This is a simple Serverless function that posts the latest tweets (in our case, @CovidVaccineBA) to a Discord channel.

The serverless.yml file is excluded here because it contains secrets. Sorry, I didn't want to spend the time digging into Serverless documentation to figure out how to do it the right way. (But feel free to ask for help if you need it!)

Pre-requisites

• An AWS account.
• A DynamoDB table named 'fauci-bot' (it's hardcoded in the function, but you can change this of course) with the primary key twitter_username that is a string.
• An IAM role that has basic AWS Lambda permissions and access to GetItem and PutItem for that specific DynamoDB table.
• Twitter Developer access so you can create an application to get a Bearer Token.
• A Discord server on which you have permissions to create a webhook.

Local testing

Serverless probably provides a way to do this easily, but I simply do this:

AWS_SDK_LOAD_CONFIG=true TWITTER_AUTH_TOKEN=... DISCORD_WEBHOOK_URL=... node run.js

Local testing requires AWS credentials to be set up locally. Serverless sets this up automatically.
