Install using pip
$ pip install rizzler
> ...
Integrate with lifespan
protocol.
from contextlib import asynccontextmanager
from fastapi import FastAPI
from fastapi.requests impor Request
from fastapi.responses import HTMLResponse
from rizzler import RizzleTemplates, Rizzler
from typing import AsyncIterator, List, Tuple
@Rizzler.load_config
def rizzler_settings() -> List[Tuple[str, str]]:
return [
("command", "pnpm"),
("framework", "vue")
]
@asynccontextmanager
async def lifespan(_: FastAPI) -> AsyncIterator[None, None]:
await Rizzler.serve()
yield
Rizzler.shutdown()
app: FastAPI = FastAPI(lifespan=lifespan)
templates: RizzleTemplates = RizzleTemplates(directory="templates")
@app.get("/", response_class=HTMLResponse)
async def index(request: Request) -> HTMLResponse:
return templates.TemplateResponse("index.html", {"request": request})
RizzleTemplates
is an extension on top of Jinja2Templates
class found under starlette
However, has two overriding methods that must be placed inside the template HTML-file as such:
<!DOCTYPE html>
<html>
<head><!-- ... --></head>
<body>
{{ vite_hmr_client() }}
{{ vite_asset('pages/main.js') }}
</body>
</html>
You can run the following command once you are done customizing the front-end code under pages/
directory
to your liking.
rzl build
Example outputs for `rzl build`
$ rzl build

> INFO ✓ built in 390ms
Now you can stop using RizzleTemplates
and revert back to serving front-end with Jinja2Templates
as such
#!/usr/bin/env python3
from fastapi import FastAPI
from fastapi.requests import Request
from fastapi.responses import HTMLResponse
from fastapi.staticfiles import StaticFiles
from fastapi.templating import Jinja2Templates
app = FastAPI()
templates = Jinja2Templates(directory="dist")
@app.get("/", response_class=HTMLResponse)
def index(request: Request) -> HTMLResponse:
return templates.TemplateResponse("index.html", {"request": request})
app.mount("/", StaticFiles(directory="dist"), name="dist")
Now you have a production front-end to go with your FastAPI
application when you need.
There will probably be bugs when it comes to relative versus absolute paths in the future.
But this is good enough for many prototyping use-case and with a bit of tinkering, can replace
This library relies on the following Python dependencies.
- click - Python composable command line interface toolkit
- jinja2 - A very fast and expressive template engine
- markupsafe - Safely add untrusted strings to HTML/XML markup
- pydantic - Data validation using Python type hints
- PyYAML - Full-featured YAML framework for the Python
- rich - Rich text and beautiful formatting in the terminal
- starlette - Lightweight ASGI framework / toolkit
- tree-sitter - An incremental parsing system for programming tools
I recommend using pyenv
and uv
as the preferred tools to managing this project.
- pyenv - Simple Python version management
- uv - An extremely fast Python package and project manager, written in Rust.
To contribute to the project, fork the repository and clone to your local device and development dependencies including four extra libraries not included in final builds as such: Alternatively, run the following command on your terminal to do so:
uv sync --dev
- mypy Optional static typing for Python
- ruff An extremely fast Python linter and code formatter, written in Rust.
