Sign Bunny, PLZ!

How It Works

This bot is built upon two Lambda Functions

• fetchMentions checks for new mentions. This runs every 5 minutes, publishing the mentions as a new notification on an SNS topic
• sendTweet is triggered by SNS Notifications. It processes the tweets and replies with a formatted sign.

Prior Art

Based largely on DownloadThisVideo, another Twitter bot using the same AWS Lambda/SNS setup

Notes

Formatting text with a non-monospace font is not a trivial task, so currently we're just avoiding the issue and keeping things left aligned and letting words run off the sign.

We could convert the text to Unicode monospace, but that's not a 1-to-1 response. Potentially another cool bot, though.

(Twitter's font stack is 14/20 "Helvetica Neue", Helvetica, Arial, sans-serif)

TODO

Genericize this stack to build a ReplyBot NPM Module?
