A bot that turns Slack into a legitimate Texas Hold'em client. Start a game in any channel or private group with 2-10 players. PokerBot will deal hands, direct message players with their hole cards, query players for their action, determine the winning hand, and handle the pot.
See it in action.
- Create a new bot integration
- Follow the steps to deploy the bot to Heroku or run it locally
- Once the bot is running, start a game with:
@<your-bot-name>: deal
- Install Heroku toolbelt
- Create a new bot integration (as above)
heroku create
heroku config:set SLACK_POKER_BOT_TOKEN=[Your API token]
git push heroku master
- Create a
token.txt
file and paste your API token there npm install
npm start
- For help,
@<your-bot-name>: help
. - To start a game,
@<your-bot-name>: game
. Players will have some number of seconds to sign up by replying with 'yes'. - To deal the next hand,
@<your-bot-name>: deal
. - To increase the blinds * 2,
@<your-bot-name>: increase blinds
- To end a game,
@<your-bot-name>: quit
. The game will end once the current hand finishes. Note that any player can end a game at any time with this command, so Be Honorable™. - To configure some bot options,
@<your-bot-name>: config <name-of-option>=<value>
. The supported options are:
timeout: Sets the duration (in seconds) before a player bet times out.
Set to 0 to specify no timeout.
So, to start a game without any player timeout, say:
@<your-bot-name>: config timeout=0
@<your-bot-name>: game
Check the open issues for some planned enhancements.
Although this client was built for managing human players in a Slack channel, it has some support for AI players. To add a bot player:
- Add a bot class under the
ai/
folder - Implement
getAction
, which is called whenever it is the bot's turn - Modify the
addBotPlayers
method insrc/bot.js
to add your bot to every game
To run tests, simply do:
npm test
The tests produce legible output that matches what users in Slack would see. This is the same test suite that is run on each pull request. This is very helpful when diagnosing a logic bug:
-
NodeJS Slack Client
node-slack-client
abstracts the basics of a Slack bot, including authentication, getting messages from players, and posting messages or attachments to the channel. -
RxJS The majority of this client is written using
RxJS
. It simplifies many of the complex player polling interactions, that would otherwise be Death By Timers, into very legible code. -
Jimp / JavaScript IMage Processor Each card is a separate image, and board images are created on the fly by pasting several cards onto a single canvas (with the help of
jimp
). The resulting image is than uploaded toimgur
, which gives us a single URL that can be passed as an attachment to the Slack API. This route was chosen to avoid uploading 318,505,200 images to the cloud, and allows us to modify the card assets easily. -
Poker Evaluator
poker-evaluator
is used for evaluating the winning hand when it comes time to show down. Here it has been extended to calculate the best 5-card hand from any 7-card hand. -
MochaJS Most of the tricky client logic is backed up by tests, which were written using
MochaJS
.
