hstream 0.0.10

Create python webapps with ease

HStream

Easiest interactive python web app using htmx and semantic html

Usage

pip install hstream

# main.py

from hstream import hs

hs.text_input('What's your name?', default_value = 'friend')
hs.markdown(f"Welcome {visitor_name}")

python -m hstream main.py

Motivation

Love Streamlit but:

• find it hard to deploy
• impossible to customise beyond PoC phase
• overly complicated

H-(html)-Stream stream is built with semantic html, FastApi and htmx to provide a fast and simple framework for rapid web app developmenet that follows traditional frontend/server architecture (or atleast follow it closer than Streamlit).

Features

• only reloads changed components after the visitor provides input
• live server reload on file change (through univorn)
• semantic html and basic html manipulation from within script
• basic components - see below
• swap stylesheet
• auto ssl certs for easy deployment
• complex html manipulation from within script (setting attributes)

Components

hs.teax_input

hs.checkbox

hs.slider: numeric slider input

hs.plot: output matplotlib figures to the user

hs.image: display an image

hs.html: allows more complex formatting, for example

hs.stylesheet_href = https://unpkg.com/@vladocar/basic.css@1.0.3/css/basic.css to use a diffrent classless css framework

with hs.html('form'):
    hs.text_input('Name'):
    hs.checkbox('Would you like to be my firend?')
