安装部署要点（README 精选）

Installation

Since fasthtml is a Python library, you can install it with:

pip install python-fasthtml

In the near future, we hope to add component libraries that can likewise
be installed via pip.

Usage

For a minimal app, create a file “main.py” as follows:

**main.py**

from fasthtml.common import *

app,rt = fast_app()

@rt('/')
def get(): return Div(P('Hello World!'), hx_get="/change")

serve()

Running the app with python main.py prints out a link to your running
app: http://localhost:5001. Visit that link in your browser and you
should see a page with the text “Hello World!”. Congratulations, you’ve
just created your first FastHTML app!

Adding interactivity is surprisingly easy, thanks to HTMX. Modify the
file to add this function:

**main.py**

@rt('/change')
def get(): return P('Nice to be here!')

You now have a page with a clickable element that changes the text when
clicked. When clicking on this link, the server will respond with an
“HTML partial”—that is, just a snippet of HTML which will be inserted
into the existing page. In this case, the returned element will replace
the original P element (since that’s the default behavior of HTMX) with
the new version returned by the second route.

This “hypermedia-based” approach to web development is a powerful way to
build web applications.
