Step through the commits to follow the project as we derive a multi process voting server from a simple function with an accumulator to hold votes.
When you're through with this, you may be interested in checking out the more full-featured Phoenix version of this application. It utilizes GenServer to run the actual Vote server under the app's supervision.
To start the console to play with the demo:
- Navigate to the project directory
- Run
iex -S mix - Start the server process with:
{:ok, pid} = ArtprizeVote.start_server - Send your votes to the server process:
send pid, {self, :add_vote, {16, 69, {-85.6, 43}}}, etc... - Check the messages the server sends back to the main process by running
flush
