A web server written in Ruby using Sinatra and a Sidekiq backend processing jobs written in Crystal.
In the web directory, run bundle install to install dependencies.
In the worker directory, run make to build the binaries.
To start the Ruby web server: cd web && rackup
To start the Sidekiq server: cd worker && bin/sidekiq
To start the Sidekiq web dashboard: cd worker && bin/web
Open up http://localhost:9292 to have the Ruby web process queue up a job in Redis. The job will be processed by the Crystal worker. Open up http://localhost:3000 to see the Sidekiq dashboard update the number of jobs processed.
