A Hubot script to quickly search for an Android app and provide a Playstore link if it exists

appsearch.coffee

# Description:
#   Quickly look up an Android application using 42Matters search
#
# Configuration:
# 
# HUBOT_42MATTERS_ACCESS_TOKEN - the access token required for API accesss
#
# Commands:
#   hubot app - Replies with the first result from an app search on 42Matters API
#

access_token = process.env.HUBOT_42MATTERS_ACCESS_TOKEN

module.exports = (robot) ->

  robot.respond /app ?\s(.*)/i, (msg) ->
    query msg, msg.match[1], (body, err) ->
      return msg.send "I had some problems looking up that app. Oh dear." if err
      
      unless access_token?
        msg.send "I need a 42Matters API token to be set to help you with that."
        return;
      
      body = JSON.parse body
      return msg.send "I can't seem to find that app. Strange." if body.results.length == 0
      app = body.results[0]
      trimmedDescription = app.description.split "\n", 1

      msg.send "Title: #{app.title}\nDownloads: #{app.downloads}\nDescription: #{trimmedDescription}\nLink: #{app.market_url}"


query = (msg, searchterm, cb) ->
  msg.http("https://42matters.com/api/1/apps/search.json?q=#{searchterm}&limit=1&access_token=#{access_token}")
    .get() (err, res, body) ->
      cb(body, err)

I would definitely suggest checking that access_token is set before using it and warn the user. Check out https://github.com/github/hubot/blob/master/docs/scripting.md#environment-variables for some examples.

Done!
