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.

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>
    </>

IDE Support

Type checking, completions, hover docs, go-to-definition, rename, and semantic highlighting — all working inside fragment syntax.

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.
