starhtml 0.1.18

Modern HTML generation in Python, inspired by FastHTML

StarHTML

A Python-first hypermedia framework, forked from FastHTML. Uses Datastar instead of HTMX for the same hypermedia-driven approach with a different flavor.

Installation

pip install starhtml

Quick Start

from starhtml import *
from starhtml.datastar import ds_text, ds_on_click, ds_signals

app, rt = star_app()

@rt('/')
def home(): 
    return Div(
        H1("StarHTML Demo"),
        # Client-side reactivity with signals
        Div(
            P("Count: ", Span(ds_text("$count"))),
            Button("++", ds_on_click("$count++")),
            Button("Reset", ds_on_click("$count = 0")),
            ds_signals(count=0)
        ),
        
        # Server-side interactions
        Button("Load Data", ds_on_click("@get('/api/data')")),
        Div(id="content")
    )

@rt('/api/data')
def get():
    return Div("Data loaded from server!", id="content")

serve()

Run with python main.py and visit http://localhost:5001.
