I typically build a SPA and serve that with Quart
It even works as a single page application including deeplinks and React Router if you set your endpoints in a correct way
Currently I'm using middleware around the asgi app, but it would be nice to have access to request variables within my called functions
right now i'm manually parsing
scope['query_string'] and the headers etc again myself
Do you need to guarantee the task doesn't start till the response has completed?
it's working as I want it to with middleware at the moment, I just thought it would be nice to have that flask functionality
i was reading the quart source and wrapping the asgi app seems to be the only "hook" to execute functions after the request has closed
Please could you open an issue for this - although I'll likely only add if Flask also adopts it, or it is clearly an async only feature
@pgjones flask already supports it via Werkzeug: https://stackoverflow.com/questions/48994440/execute-a-function-after-flask-returns-response
since flask uses Werkzeug request/response objects
but thanks, will stick an issue on github later

Hello! @pgjones I created an pgjones/quart#118. Should I recreate it on
GitLab? Thanks your help in advance.
Hello, I'm trying to run my Quart application with Flask_SQLAlchemy (and thus with flask_patch) inside a Docker container with uvicorn as ASGI server and I'm getting the
In hindsight, I should've probably started with hypercorn-based Docker, but I couldn't find anything readily available at the time.
Can you please either advise on how to make it work with uvicorn or recommend a hypercorn-based Docker image that can run quart?

Hello! Is it possible to extract the different IP addresses of different adapters? I mean when I set hypercorn to serve my site on
0.0.0.0 it means that on localhost it will 127.0.0.1 on wireless it will 10.42.1.12 and etc. So is it possible to know all? Thanks in advance!

I've released Quart-Schema, 0.6.0. The headline feature is easier automated testing, as I explain in this article, https://pgjones.dev/blog/automatic-api-testing-2021/
On quart-schema, is it possible to get the pydantic ValidationError that raised the RequestSchemaValidationError? On my API, I'm thinking of showing which fields did the API user fail to provide or provided incorrectly on a 400, but the given RequestSchemaValidationError does not have any other context
*reading the documentation I have understood that despite it is global, it’s global only inside the executed handler. So in case I have 2 endpoint handlers running concurrently, they both will have their global request, and I won’t have any problem that accessing request from endpoint handler A, I am reading the request of handler B because race conditions?
since it’s globally I’m scared that accessing request from an handler I could access the request of another concurrent user and reply to the first user with the data of the second user. but I from the context doc page that it shouldn’t happen, but I would like to be sure I understood right
You do understand this right. Each request is handled in a separate asyncio Task, which means we can isolate the request information to that task using a ContextVar. Here is a test to ensure this works
hi all, we've just released an alpha of a collaboration platform for students and supervisors, built on quart-trio
a test deployment is running on hypercorn, which can be found at https://acanban.ga/p (all ipsum projects' users have their passwords spells backward, e.g. oliviak:kaivilo)
the software is under AGPLv3+, available at https://github.com/Huy-Ngo/acanban
we would like to take this chance and thank @pgjones for the support we've received in the last few months as well
Really nice. For reference I think you could add a few secure headers to your html routes e.g. these and a CSP. You may also want to add Quart-Rate-Limiter before some inconsiderate scraper pops by.
It is cool to set it responding over HTTP/2. HTTP/3 is almost standardised now - chrome already switched to it - so that may be fun to try at some point.

Also what is quart-trio-twice?
i don't think we use and http/2 feature though, it's just hypercorn default I guess
quart-trio-twice is a temporary fork of quart-trio 0.6 (3 times 2 is 6) with some patches added: we haven't found the time to migrate to quart 0.14+ / quart-trio 0.7+
there is some issues with mypy and inheritance iirc but I haven't looked into it for quite a while
hello, i was trying to figure out how the config files should be done in hypercorn, but i found 0 examples unfortunately. as far i as i got reading the documentation i have to insert the parameters in config.py as global variables. anyways hypercorn is ignoring those variables
i post the example file i wrote
import asyncio
from quart import Quart
from hypercorn.asyncio import serve
from hypercorn.config import Config
app = Quart(__name__)
@app.route('/')
async def hello():
return 'hello'
if __name__ == '__main__':
config = Config()
config.from_pyfile("config.py")
asyncio.run(serve(app, config))this is my config.py
bind = '0.0.0.0:3068'anyways issuing python3.7 main.py it starts it [INFO] Running on http://127.0.0.1:8000
i think the config.py should not be written this way if getting ignored.
can someone give me a hint? thank you and sorry to bother you
