Link shortener front end

Host your own link shortener that works with a bot. Just send the link to a bot and it'll take care of the rest for you. Demo: @GiveMeShortLinkBot

This is the backend (nevermind the repo name) for the link shortener. You need a bot to add links to this link shortener. For source code of the bot see tommyku/link-shortener-bot

Getting Started

1. Make sure you have Ruby 2.3.1+ installed and a Firebase database set up
2. Run bundle install from project root folder
3. Set the environmental variables FIREBASE_BASE_URI and FIREBASE_SECRET_KEY in your environment
4. To push some data into the Firebase database, use bundle exec irb:

irb> require 'firebase'
irb> firebase = Firebase::Client.new(ENV['FIREBASE_BASE_URI'], ENV['FIREBASE_SECRET_KEY'])
irb> firebase.push('appleorange', 'https://github.com/tommyku/link-shortener-front-end')
irb> response = firebase.get('appleorange')
irb> response.body
{'-somefirebasekey': 'https://github.com/tommyku/link-shortener-front-end'}

4. To run the server locally, run bundle exec ruby app.rb and navigate to http://localhost:3000/appleorange, you should have been redirected to https://github.com/tommyku/link-shortener-front-end

Prerequisites

1. Ruby 2.3.1+

(local)$ scp link-shortener-front-end username@production-server:~/link-shortener-front-end

(prod)$ docker load -i link-shortener-front-end

Run the image

From the project folder,

$ docker run -e FIREBASE_BASE_URI=FIREBASE_BASE_URI -e FIREBASE_SECRET_KEY=FIREBASE_SECRET_KEY -e PORT=3000 -p 3000:3000 link-shortener-front-end
