This is a fully local (no backend) version of the Teemo Tool project's web frontend.
It watches Twitch chat by using Twitch's IRC interface and tmi.js. OAuth is unnecessary because we are only reading messages.
If running the site locally, serve it from a local HTTP server to avoid CORS issues that crop up when accessing local files like the dependencies in the js folder. A simple way of doing this is with Python's SimpleHTTPServer. In the root directory of this project, run python -m SimpleHTTPServer 8000 and then navigate to localhost:8000 in your browser.
Use document.test("!blue 100") (for example) in the browser console to
simulate receiving a message of !blue 100 from username tester. Use
document.sendSampleInput() in the console to simulate receiving multiple
bets (successful and unsucessful) from a variety of users. See the source code
for the expected result values.
