Hi!
I have a small problem understanding something. Maybe someone can help.
Example: A simple application should display an HTML page with an image. The image is located in the static folder.
When I start the app.py with "emmett -a app develop" everything is fine.
However, when I start the app using "python3 start.py" with “run()”, the image in the static folder cannot be found.
Does anyone have any idea? (emmett 2.7 / Python 3.11.2)
Thanks a lot!
Lu

start.py (python3 start.py ... picture.jpg not displayed)

### start.py ###
from emmett_core.server import run

def main():
    run( interface="asgi", app=("app", None), log_level='debug', host="0.0.0.0", port=8000 )

if __name__ == "__main__":
    main()

app.py (emmett -a app develop ... picture.jpg displayed, it s fine )

### app.py ###
from emmett import App

app = App(__name__)

@app.route("/")
async def picture_view():
    return dict()

picture_view.html

<!DOCTYPE html>
<html><head></head><body>
    <h1>Example</h1>
    <img src="static/picture.jpg" />
</body></html>

Few things:

Emmett is designed to run primarly on RSGI
- if you still want to run over ASGI and have issues with static files please fill a bug report
emmett serve probably does what you need
manually using run from emmett_core.server is not a supported way of running your application
- if you want to run from Python code, consider using Granian directly which supports and exposes all the APIs to do so

Note:
I also tried the settings:

app = App(__name__)
# app.static_path = ‘/home/user/project/static/’
# app.static_folder = ‘/home/user/project/static/’

@1st-github-account Interesting. Can you send over your app.py and start.py or your whole project. I want to dig under the hood of Emmett and check if it's a path issue or run doesn't support something related to static or what.

EDIT: removed zip file

Thank you for your help! Consider this example as a project. It should work, right? (please see attached file) I use Debian 12, emmett 2.7 and python 3.11.2.
Thanks a lot!
