websocket-midi-server

MIDI note echoing between browsers using WebSockets. Server written in Python

Server

Flask server. Python 2 is fine (and Python 3 virtual environments are broken in macOS.) Create and activate a virtual environment:

virtualenv ~/Desktop/venv2
. ~/Desktop/venv2/bin/activate

Install packages:

pip install flask
pip install flask-socketio
pip install flask-cors

(flask-cors to temporarily enable cross-scripting - see here.)

See main.py for running instructions (either locally, or deployed).

Client ClojureScript/Javascript code gets planted from the websocket-midi-cljs project (see its deploy.sh). In development, the code here will attempt to connect to ws://localhost:3449.

Heroku

• instructions. Boilerplate for deploying the “getting started” Python app:

  heroku login
  git clone https://github.com/heroku/python-getting-started.git
  cd python-getting-started
  heroku create
  git push heroku master
      

• Looking through the Gunicorn guide. Need to add Gunicorn to deps, and Eventlet:

  pip install gunicorn
  pip install eventlet
      

• Dump out to requirements.txt:

  pip freeze > requirements.txt
