A proof-of-concept messaging framework for robotics on the web

The following two Python scripts:

Run on your local machine, not a server
Run in the background
Pass messages between each other

Edit the code, run, and mess with the demo:

echo.py

from browsermessage import publish, subscribe

subscribe("heartbeat",
  lambda m: [
    publish("response", m),
    print(f"Echoing {m.to_py()}")])

from browsermessage import publish, subscribe

subscribe("heartbeat",
  lambda m: [
    publish("response", m),
    print(f"Echoing {m.to_py()}")])

heartbeat.py

from browsermessage import publish, subscribe
import time

subscribe("response",
  lambda m: print(f"Got: {m.to_py()}"))
publish("heartbeat",
  {"time": time.time()})
print("Publish heartbeat")

from browsermessage import publish, subscribe
import time

subscribe("response",
  lambda m: print(f"Got: {m.to_py()}"))
publish("heartbeat",
  {"time": time.time()})
print("Publish heartbeat")

Explanation will be up next week 🤔...
