Bocadillo is a Python async web framework that makes server-side async web apps fun to build and accessible to everyone.
It is designed to be:
-
Productive: a carefully chosen set of included batteries helps you solve common and more advanced problems — request routing, app configuration, static files, data validation, and more!
-
Real-time capable: embrace asynchronous programming and the baked-in WebSocket and SSE support to build real-time, highly-concurrent systems.
-
Flexible: inject resources into web views using providers, an explicit, modular and easy-to-use mechanism inspired by pytest fixtures.
-
Performant: squeeze the juice out of Starlette and uvicorn, the lightning-fast ASGI toolkit and web server.
-
Empowering: use tailored testing and command line tools to build delicious, high-quality applications.
-
Transparent: every single feature is documented front to back and has optimal editor support thanks to a 100% type-annotated code base.
Quick start
We all love delicious "Hello, world!" examples, don't we? Here's ours:
- Install Bocadillo and the Bocadillo CLI:
pip install bocadillo bocadillo-cli
- Generate the project and
cdinto it:
bocadillo create hello
cd hello/
- Edit the application script:
# hello/app.py
from bocadillo import App
app = App()
@app.route("/")
async def index(req, res):
res.text = "Hello, world!"
- Start a uvicorn server (hot reload enabled!):
uvicorn hello.asgi:app --reload
- Say hello!
$ curl http://localhost:8000
Hello, world!
- Edit
app.pyto send "Hello, Bocadillo!" instead, then hit save. Uvicorn will pick up the changes and restart the application. Try it out again:
$ curl http://localhost:8000
Hello, Bocadillo!
Tastes good! 🥪
