python-fragments 0.20

Modern HTML template rendering in Python

Python Fragments

This package is in early development and not yet stable. The API may change without notice between releases.

Production-ready, modern HTML template rendering in Python — no build step, no template files, and native HTML awareness out of the box.

from fragments import loader  # isort: skip

from fastapi import FastAPI
from fastapi.responses import HTMLResponse
from components import Layout, PostCard

app = FastAPI()

POSTS = [...]

@app.get("/", response_class=HTMLResponse)
async def index() -> str:
    published = [p for p in POSTS if p.published]
    return <>
        <Layout title="My Blog">
            <h1>Latest Posts</h1>
            <PostCard for={{ post in published }} post={{ post }} />
        </Layout>
    </>

Installation

pip install python-fragments

Register the loader at your application's entry point, before importing any modules that contain fragments:

from fragments import loader  # isort: skip

Any .py file containing <> is transpiled automatically. Nothing else to configure.
