Getting Started with Hubot

Step 1: Install Node


Step 2: Install Hubot Generator

Open a terminal and run the following:

%  npm install -g yo generator-hubot

Step 3: Make a bot called ‘hodor’

% mkdir hodor
% cd hodor
% yo hubot

Now, you will be asked a few questions like who is creating the bot and adapter you want to use.

Ignore adapter part, for now, will come to it in our next blog, “Integrate Hubot to your Slack”.

Step 4: Run the functional hubot inside “bin/hubot” folder

% bin/hubot

Press enter

hodor>hodor ping

Hodor will reply with PONG.

Type hodor help to see the list of commands supported.

Now to the “hodor” folder in your system.

You can add your scripts inside the “scripts” folder. Read more about CoffeeScript here.

Open “example.coffee” in editor.

Add the following after ‘module.exports = (robot) ->’

 robot.hear /hi|hello|hey|/i, (res) ->

res.reply ‘hey, what’s up’

robot.respond /what is your name/i, (res) ->

res.reply ‘Hodor Hodor Hodor’

Stop and run hubot again by % bin/hubot

In the script, if you want hubot to reply to chat which is directed to him, use robot.respond

If you want hubot to reply even if it is not directed to him then use robot.hear

Type any of hi, hello, hey and Hubot will reply with  “hey, what’s up”

Type “hodor what is your name” and you will get the reply “Hodor Hodor Hodor”.
