Flask OTR WebRTC Demo

This project demonstrates how to implement Off The Record WebRTC chat with Flask.

Motivations behind project:

• Create simple example to experiment with
• Experiment with WebRTC
• Experiment with OTR
• Experiment with Flask + SSE
• Use SSE and not WebSockets as part of the intermediary

Installation

git clone https://github.com/spectralsun/flask-otr-webrtc-demo.git
cd flask-otr-webrtc-demo
virtualenv venv
source venv/bin/activate
pip install -r requirements.txt

Then run the development server with:

python app.py

Now you should be able to visit http://localhost:5000 in your browser.

Restarting the development server

Since this app runs multithreaded and has open streaming connections, you may find it difficult to reload python changes dynamically while the server is running. You will have to kill all the related python processes if you want to restart the development server.

I recommend using the following one-liner command to kill all running instances after you use Ctrl+C to stop python app.py. It will grep the running processes and look for app.py, end all instances and then start the server back up:

for pid in `ps aux |grep app\.py|grep -v grep|awk '{print $2}'`; do; kill -9 $pid; done; python app.py;
