The attached code features a very simple web application, consisting of a pure HTML/CSS/JS frontend and Ruby/Sinatra backend. It allows adding up to 5 passengers to a train journey, on mobile devices.
It has been poorly written on purpose. Your task is to find and fix as many problems with the code as you can find. The issues to be fixed range from straight bugs, through potential problems with security and accessibility, down to all kinds of poor engineering practices.
-
The final code genis supposed to be free of bugs, intuitive for users, and follow all the best development practices.
-
We want you to explain all the changes in your commit messages.
-
Use
YOUR_NOTES.mdto write down any additional thoughts that you haven't implemented in code. -
Do not implement any new features or install any 3rd-party libraries, although you can mention any such ideas in your notes.
-
In a terminal, run the following code to install
bundler:$ gem install bundler -
In the project root directory, run the following commands to install dependencies and launch the backend:
$ bundle install $ bundle exec ruby backend.rb -
Open the
index.htmlfile in your mobile web browser
In case you're not confident enough with Ruby, you can re-write
the backend code in another language of your choice. In such case,
please ensure the new code stays of roughtly the same size. Please
also include building & running instructions in YOUR_NOTES.md
