# PyView
> A Python implementation of Phoenix LiveView
PyView enables dynamic, real-time web apps, using server-rendered HTML.
**Source Code**: https://github.com/ogrodnek/pyview
# Installation
`pip install pyview-web`
## Quickstart
There's a [cookiecutter](https://github.com/cookiecutter/cookiecutter) template available
```
cookiecutter gh:ogrodnek/pyview-cookiecutter
```
# Live Examples
[https://examples.pyview.rocks/](https://examples.pyview.rocks/)
## Other Examples
- [pyview AI chat](https://github.com/pyview/pyview-example-ai-chat)
- [pyview auth example](https://github.com/pyview/pyview-example-auth) (using [authlib](https://docs.authlib.org/en/latest/))
## Simple Counter
[See it live!](https://examples.pyview.rocks/count)
count.py:
```python
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:
```html
Count is {{count}}

# Acknowledgements
- Obviously this project wouldn't exist without [Phoenix LiveView](https://github.com/phoenixframework/phoenix_live_view), which is a wonderful paradigm and implementation. Besides using their ideas, we also directly use the LiveView JavaScript code.
- Thanks to [Donnie Flood](https://github.com/floodfx) for the encouragement, inspiration, help, and even pull requests to get this project started! Check out [LiveViewJS](https://github.com/floodfx/liveviewjs) for a TypeScript implementation of LiveView (that's much more mature than this one!)
- Thanks to [Darren Mulholland](https://github.com/dmulholl) for both his [Let's Build a Template Language](https://www.dmulholl.com/lets-build/a-template-language.html) tutorial, as well as his [ibis template engine](https://github.com/dmulholl/ibis), 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](https://github.com/flet-dev/flet)
- PyView is built on top of [Starlette](https://www.starlette.io/).
