Requirements

• A computer running Linux
• sudo rights
• Virtualenv

Install the stuff needed

I like to keep my Python stuff in dedicated virtual environments.

virtualenv env -p python3 --system-site-packages

Let's use the installed env:

/minimal$ source env/bin/activate
(env) kallet@mm:~/minimal$ which pip
/home/kallet/minimal/env/bin/pip

Since we're in the desired env, let's install the framework:

$ pip install python-fasthtml

And make a main.py:

from fasthtml.common import *

app,rt = fast_app()

# This is a route where we'll navigate with the '/''url
@rt('/')
def get(): return Div(P('Hello Doge'), hx_get="/change")

serve()

Then run it with:

python main.py

These should be the results:

$ python main.py 
Link: http://localhost:8010
INFO:     Will watch for changes in these directories: ['/home/kallet/minimal']
INFO:     Uvicorn running on http://0.0.0.0:8010 (Press CTRL+C to quit)
INFO:     Started reloader process [381100] using WatchFiles
INFO:     Started server process [381106]
INFO:     Waiting for application startup.
INFO:     Application startup complete

So now we have a web server running locally!

That was actually quite fast.
