    Make your team hyper-productive with cutting Chuck Norris jokes

    The NorrisBot is a Slack bot that kicks asses, roundhouse-kicks to be precise... It's super-powered with Chuck Norris jokes and it aims to make your Slack channel even more "slacker" and enjoyable.

    Chuck Norris face

    NorrisBot is loaded with guns and jokes about Chuck Norris and it will tell a random joke every time that someone says “Chuck Norris” or "norrisbot" in a slack channel.

    Norrisbot in action


    As simple as installing any other global node package. Be sure to have npm and node (>= 4.3.2 version) installed and launch:

    $ npm install -g norrisbot

    Alternative Installation (binaries)

    From release 2.0.3, every release comes also with dependency-free binaries for linux, mac and windows that can be downloaded in the Releases page on GitHub.

    Running the NorrisBot

    To run the NorrisBot you must have a valid Slack BOT token to authenticate the bot on your slack organization. Once you get it (instructions on the next paragraph) you just have to run:

    NORRISBOT_TOKEN=somesecretkey norrisbot

    Once the bot is up and running, you need to invite him into the channels you want it to be available in.

    Getting the BOT token for your Slack channel

    To allow the NorrisBot to connect your Slack channel you must provide him a BOT token. To retrieve it you need to add a new Bot in your Slack organization by visiting the following url:, where yourorganization must be substituted with the name of your organization (e.g. Ensure you are logged to your Slack organization in your browser and you have the admin rights to add a new bot.

    You will find your BOT token under the field API Token, copy it in a safe place and get ready to use it.

    As an alternative you can create a bot by creating a custom application in the Slack developer portal. Inside the application settings you will be able to add a bot user and retrieve a OAUTH BOT token for it.


    The NorrisBot is configurable through environment variables. There are several variable available:

    Environment variable Description
    NORRISBOT_TOKEN The Slack Bot User OAuth Access Token for your organisation/team (mandatory)
    NORRISBOT_TRIGGERS A coma separated list of words that triggers the bot to reply with a joke (default: "Chuck Norris,norrisbot")
    NORRISBOT_CATEGORIES A coma separated list to enable special joke categories like "explicit" and "nerdy" (default: "nerdy")
    NORRISBOT_NO_PICTURES If set to TRUE will disable pictures in jokes (default: FALSE)
    NORRISBOT_MESSAGE_COLOR The hex color used by the bot to mark it's messages (default: "#590088")

    Installing on Heroku

    A great place where to deploy our lovely NorrisBot is Heroku. We can go reasonably well with their free worker tier and the deploy process is reasonably easy and convenient. Let’s see how we can do that.

    I am assuming you already have and account on Heroku and that you have installed and configured the Heroku toolbelt on your machine.

    1. Create a new Heroku app

    Create a local folder and install norrisbot on it:

    mkdir norrisbot-myorg
    cd norrisbot-myorg
    npm init -y
    npm i --save norrisbot

    Then create a new app on heroku:

    heroku create norrisbot-myorg

    2. Configure your Heroku app:

    heroku config:set --app norrisbot-myorg NORRISBOT_TOKEN=xoxb-YOUR-AWESOME-BOT-TOKEN

    (of course you need to replace xoxb-YOUR-AWESOME-BOT-TOKEN with your actual token).

    You can add extra configuration by defining values for the other supported environment variables if you want to customize the behavior of the bot.

    3. Initialize your Heroku app

    Create an Heroku Procfile (service definition)

    echo "worker: node_modules/.bin/norrisbot" >> Procfile

    Then prepare the project to be published through git:

    git init
    echo "node_modules/" >> .gitignore
    git add --all
    git commit -am "first version"
    heroku git:remote --app norrisbot-myorg

    4. Publish and launch the Heroku app

    Through heroku git

    git push heroku master

    Stop the web app (not present but started by default by Heroku) and run the worker:

    heroku ps:scale web=0 worker=1

    That's it, now go on your Slack organization and start enjoying Chuck Norris jokes! 😂

    Building the bot from source

    If you downloaded the source code of the bot you can build the bot with

    npm run build

    Then you can run it with:

    $ npm start

    Don't forget to set your NORRISBOT_TOKEN environment variable bedore doing so and to install all the dependencies (including dev ones with NPM or Yarn).

    Bugs and improvements

    If you find a bug or have an idea about how to improve the NorrisBot you can open an issue or submit a pull request, it will definitely make you a better person! :P

    The Making of

    Version 1 of NorrisBot has been developed in collaboration with A very detailed article has been published to explain every single line of code. It also explains you how to deploy the bot on a free Heroku instance, so you should give it a shot!
