setup_toasts() broken or mis-documented

css = Style(':root {--pico-font-size:90%,--pico-font-family: Pacifico, cursive;}')
sse = Script(src="https://unpkg.com/htmx-ext-sse@2.2.1/sse.js")
hdrs = (css, sse)
app, rt = fast_app(hdrs=hdrs, live=True)

setup_toasts(app)

Gives compile time error of

  File ".../.cache/pypoetry/virtualenvs/story-writer-s9Ds3i4O-py3.12/lib/python3.12/site-packages/fasthtml/toaster.py", line 57, in setup_toasts
    app.router.hdrs += (Style(toast_css), Script(toast_js, type="module"))
    ^^^^^^^^^^^^^^^
AttributeError: 'RouterX' object has no attribute 'hdrs'

I've tried diagnosing it unsuccessfully.

Removing headers doesn't help.

If you update FastHTML to the the latest version currently v0.6.8. Do you still have that issue?

@talkingtoaj I can't replicate your error. Here's my sample code, which uses your example as a base. If you can provide a reproducable error let me know with a flag to @pydanny and I'll reopen this ticket.

from fasthtml.common import *

css = Style(':root {--pico-font-size:90%,--pico-font-family: Pacifico, cursive;}')
sse = Script(src="https://unpkg.com/htmx-ext-sse@2.2.1/sse.js")
hdrs = (css, sse)
app, rt = fast_app(hdrs=hdrs)

setup_toasts(app)

@rt
def index(sess):
    return Titled('Hello, world',
    P(A(href='/toast-test')('Toast test'))
    )

@rt('/toast-test')
def get(sess):
    add_toast(sess, 'This is a toast')
    return Redirect('/')
