Summary
Slack-DotA is a bot for Slack that records my friends DotA 2 game results. Every time a friend (or a group of friends) finishes a game, the bot posts a link to the result page.
Around
DotA 2 is a very competitive game and you can have access to a lot of data. Having an easy way to be notified and to access this data is fun and convenient.
Technical stuff
My script runs with NodeJS. It requests OpenDotA API to gather game results and uses Slack SDK to display those results.
