- Based on watchdog.
- Works on Python3.7+
- [aiohttp-debugtoolbar](https://github.com/aio-libs/aiohttp-debugtoolbar) included ,thus you can get a full report of traceback if exception raised.

## Install
pip install aiohttp-debugmode
## Usage
`quick_start.py`
\# here's a demo script from aiohttp.doc\\quickstart
```Python3
from aiohttp import web
routes = web.RouteTableDef()
@routes.get('/')
async def hello(request):
return web.Response(text="Hello, world")
app = web.Application()
app.add_routes(routes)
web.run_app(app)
```
Simply modify severl lines like this
```Python3
# Add import
from aiohttp_debugmode import Debugmode
# Let Debugmode take over control of run_app
Debugmode.run_app(app)
```
By default ,`templates` & `static` floder is added to observing list of watchdog. You can manually set observe file/floder using append_observe.
```Python3
Debugmode.append_observe(['other/login.html' ,'assets'])
```
If you need some kind of process when a aiohttp server starts up:
```Python3
def stup():
... # do something
Debugmode.on_startup(stup) # accepts callable.
```
## Examples
### aiohttp-debugmode with Vue
Assume that you are usiung vue-cli and have a directory structure like this:
```
...
├── Project
│ ├── static
│ ├── templates
│ ├── app.py # aiohttp app entry
│ └── frontend # vue frontend folder
│ ├── dist # webpack output directory
│ │ ├── css
│ │ ├── js
│ │ └── index.html
│ ├── node_modules
│ │ └── ...
│ ├── src # vue source
│ │ └── ...
│ └── vue.config.js
│ └── ...
```
Assume that webpack outputs built file into `/Project/frontend/dist` floder while your aiohttp app collects templates & statics from `/Project/templates` & `/Project/static` folder.
Here's a sample code:
```Python3
from aiohttp import web
from aiohttp_debugmode import Debugmode
import aiohttp_jinja2
# Pretended doing some tempate rander stuff.
# @aiohttp_jinja2.template('index.html')
async def hello(request):
return web.Response(text="Randered.")
# Debugtoolbar included thus you can get
# a full report of traceback.
async def error(request):
raise Exception('Testing.')
app = web.Application()
app.router.add_route('GET', '/', hello)
app.router.add_route('GET', '/err', error)
app.add_routes([web.static('/', 'static')])
def initialize():
import shutil , os , glob
# You may use os.path.abspath to get absolute path in some situation.
if os.path.exists('frontend\dist\index.html'):
shutil.move('frontend\dist\index.html' , 'templates')
try:
shutil.rmtree(filepath)
os.mkdir(filepath)
for filepath in glob.glob('frontend\dist\*'):
shutil.move(filepath , 'static')
except Exception as e:
raise e
Debugmode.append_observe(['frontend\dist']) # backslashes on windows.
Debugmode.on_startup(initialize)
# Debugmode takes over run_app instead of web.run_app
Debugmode.run_app(app , host = '127.0.0.1' , port = 8080)
```
Thus every time you run `npm run build` ,debugmode will catch file modified event ,init file directory and restart aiohttp server with new generated html/js/css file.
