Hot Reloading

[knoopx]

Does idom support any kind of hot reloading? can it be used with other python reloading mechanisms?

As explained here, IDOM can be run using a variety of different web servers. As such, whether hot-reloading is supported and how to enable it depend on you choice of server. For example, to enable hot-reloading in Flask, we can write the following:

# hello.py

from flask import Flask

from idom import component, html
from idom.backend.flask import configure

@component
def HelloWorld():
    return html.h1("Hello, world!")

app = Flask(__name__)
configure(app, HelloWorld)

And then follow the flask documentation on how to run with hot-reloading:

flask --app hello --debug run

If you chose a different server implementation, this answer would change. Like if you used one of the supported ASGI servers (e.g. FastAPI) and ran it with uvicorn, you'd need to follow Uvicorn's directions on reloading behavior instead.

It would be nice if the run function had an argument autoreload or hotreload that could be set True, instead of using the configure approach above.

That would definitely be preferable. I think that we may even turn that on by default since the run function is explicitly meant to be used during development and not in production. #990
