Simple Counter
See it live!
count.py:
from pyview import LiveView, LiveViewSocket
from typing import TypedDict


class CountContext(TypedDict):
count: int


class CountLiveView(LiveView[CountContext]):
async def mount(self, socket: LiveViewSocket[CountContext], _session):
socket.context = {"count": 0}

async def handle_event(self, event, payload, socket: LiveViewSocket[CountContext]):
if event == "decrement":
socket.context["count"] -= 1

if event == "increment":
socket.context["count"] += 1

async def handle_params(self, url, params, socket: LiveViewSocket[CountContext]):
if "c" in params:
socket.context["count"] = int(params["c"][0])

count.html:
<div>
<h1>Count is {{count}}</h1>
<button phx-click="decrement">-</button>
<button phx-click="increment">+</button>
</div>

Acknowledgements


Obviously this project wouldn't exist without Phoenix LiveView, which is a wonderful paradigm and implementation. Besides using their ideas, we also directly use the LiveView JavaScript code.


Thanks to Donnie Flood for the encouragement, inspiration, help, and even pull requests to get this project started! Check out LiveViewJS for a TypeScript implementation of LiveView (that's much more mature than this one!)


Thanks to Darren Mulholland for both his Let's Build a Template Language tutorial, as well as his ibis template engine, which he very generously released into the public domain, and forms the basis of templating in PyView.


Additional Thanks

We're using the pubsub implementation from flet
PyView is built on top of Starlette.

Status
PyView is in the very early stages of active development. Please check it out and give feedback! Note that the API is likely to change, and there are many features that are not yet implemented.
