Javascript runner for code retreat

Getting set up

The first step is to run the script bin/addToPath.sh. This will add the JavaScript, Ruby and Python wrappers to your PATH for your current session.

What do I do

• Run coderetreat NAMEOFMYFILE
• Edit file in your editor, add some tests
• Save!
• Look at the terminal output for test results
• Rinse and repeat

Local testing

You can use netcat to simulate the server and send messages:

netcat -lp 8787

Messaging

The coderetreat wrapper communicates with a central stats-collecting server using simple stream connections and JSON payloads.

Stats update

Whenever a test is run the stats are posted to the server in the following format:

{
  "action": "consumeTestsResults",
  "payload": {
    "testsRun": 10,
    "testsFailed": 5,
    "testsIgnored": 2
  }
}

This is the only unsolicited transmission from client.

Process an iteration

The server requests an iteration:

{
  "action": "processIteration",
  "payload": {
    "generation0": "000011101010101110111101101"
  }
}

The client responds with the next iteration:

{
  "respondingTo": "processIteration",
  "payload": {
    "generation0": "000100100111101011101011010101",
    "generation1": "000100100111101011101011010101",
  }
}

or an error:

{
  "respondingTo": "processIteration",
  "payload": {
    "error": "The function could not be executed."
  }
}

Provide information about the team (OPTIONAL)

To build a running commentary of who has worked on which session/table, the server requests the team information:

{
  "action": "getClientInfo",
}

In turn the client responds with information about the team members:

{
  "respondingTo": "getClientInfo",
  "payload": {
    "team": [
      {"name": "Ryan Brooks"},
      {"name": "Ben Foxall"}
    ],
    "session": 0,
    "language": "javascript",
  }
}
