This completes the requirements for the take home challenge provided by Sezzle.
I chose to write it in Rails with a react front-end bootstrapped by webpacker. I chose this stack because it came with many of the required pieces out of the box with minimal friction (with one notable caveat). Getting it running locally is a very quick process.
I have detailed setup instructions for getting it working on OSX. I have also included a note about a particular challenge that made the final steps difficult.
Dependencies
- homebrew
- ruby 2.6.3
- node 10+
- postgresql
brew install postgresql - foreman
gem install foreman
-
After cloning the repo, install dependencies:
bundle install yarn install -
ensure that postgres is running:
brew services start postgresql -
create and migrate the database:
rake db:create rake db:migrate -
start the dev server through foreman:
foreman start -f Procfile.dev -
navigate to
localhost:5000
I initially had difficulty getting the front-end to subscribe to the RecentEquation channel through action cable. It turns out it was because there is a bug in the @rails/actioncable npm package. I ended up trying 2 other react-specific implementations before getting it to work. I chose this tech stack specifically because I knew that actioncable was very quick to get working. This diversion ended up doubling the time it took to complete this challenge, but i got it working in the end.
