A quick little slack bot to report of brexit results

_brexit.md

This is a little slack bot I made which is used to get results for the EU Referendum in the UK

Set up

npm install cheerio botkit request

Log into slack, create a new bot and then get the token for it.

Drop the token into the brexitbot.js file where it says "PUT YOUR TOKEN HERE"

Then

node brexitbot.js

Interacting

Invite the bot to your channel and then you can ask it questions like "@brexitbot who is winning?" or "@brexitbot what are the latest results" etc and it will give you a variety of responses fresh from the BBC referendum results site.

            var $ = cheerio.load(html);
