Sanic: [Suggestion]: auto reload

[abersheeran]

When the code be changed with DEBUG=True，Server will reload like flask.

Why not do that？

You can use sanic-admin

[abersheeran]

I've already written a tool to manage it. Thank your help.
But I think it would be better if sanic built this feature.

You can use the library AoikLiveReload to do that.

Take a look at the demo here:
https://github.com/AoiKuiyuyou/AoikLiveReload/blob/master/src/aoiklivereload/demo/sanic_demo.py

To enable auto reloading developer must pass "auto_reload=True" to "run" method of Sanic app.

[abersheeran]

Really? I don't know that but I will try soon after class. I'm a student😳

@Yaser-Amiri
Hey, I try it, but get a TypeError

Traceback (most recent call last):
  File "main.py", line 55, in <module>
    main.run("0.0.0.0", 8000, debug=True, auto_reload=True)
TypeError: run() got an unexpected keyword argument 'auto_reload'

Is there anything I've overlooked?

it's app.run https://github.com/channelcat/sanic/blob/master/sanic/app.py#L652.

[abersheeran]

Thank your help. Don't have this parameter in the version I installed with PIP. I will update Sanic from github. @yunstanford

[yunstanford]

@Yaser-Amiri can you double check the unit test here ? https://github.com/channelcat/sanic/blob/master/tests/test_auto_reload.py
it's actually failing on my side, and might also try refactor a little bit, it's not very pytest style.

[Yaser-Amiri]

@yunstanford Sorry about late.
I pulled repo now and ran tests, all tests passed (Python 3.6) and auto-reloading works correctly. About refactoring you are right, it's not very pytest style and I'll refactor it as soon as possible.
