Fizzbuzz app

Demo

For an easily accessible demo, check out the app on Heroku! https://fizzbuzz-rails-app.herokuapp.com/

Install

Clone this project.

git clone git@github.com:alexpapworth/fizzbuzz-app.git

Run the database migrations.

cd fizzbuzz-app
rails db:migrate

The numbers and fizzbuzz results are generated on the fly depending on your page number.

def check_fizzbuzz(number)
	"#{"fizz" if number.to_i % 3 == 0}#{'buzz' if number.to_i % 5 == 0}".capitalize
end

Features

Signup

To create a new account, click the Sign Up button. The app doesn't use passwords, and a username will be automatically assigned for you.

Login and out

Once an account is signed up, you can log into it again by entering the name. Note that the same user can be logged into multiple browsers at once. Sessions persist on each browser until you log out, or clear your cookies. Shut down the browser to test it out!

Favourite a number

Click the star to favourite a number. This will persist between logins. You can see a tally of how many users favourited a number on the last column.

User hover

If you hover on the tally, you'll see a list of which users favourited the number.

Change page number

The app needs to show up to 100,000,000,000 numbers, and calculate fizzbuzz on them. Saving that much data to the database doesn't make sense at this level, so instead they're generated on the fly. Feel free to jump to the last page to test it out.

Change page size

You can also change the number of results for each page. Options of 20, 50, 100 and 250 are available through the GUI, but you can also modify the URL if you want more specific number.

Tests

This app comes with some simple tests to get you started. We test two main things. Models and controllers.

To run all the tests, simply type the following from inside the fizzbuzz-app directory.

rails test

For just the model tests, use:

rails test test/models/

For just the controller tests, use:

rails test test/controller/

Further reading

This app comes with a companion API! It's written with NodeJS and can be found over in the fizzbuzz-api repo.

You can do cool things like authenticating a session, and favouriting/unfavouriting numbers as that user. It has extra features like being able to specify a username when creating a user.
