# Introduction.
This asynchronous framework with a modular structure like Django. But with mongodb, jinja2, websocket out of the box,
and more than a simple barrier to entry.

Built on the basis of asyncio and aiohttp.

#Framework Installation
```bash
$ pip install tao1
```
#Getting Started

Create a project anywhere:
```bash
utils.py -p name
```
Create an application in the folder of the project apps:
```bash
utils.py -a name
```
Run server:
```bash
python3 index.py
```
#License

It's *MIT* licensed and freely available.

#Deploy
When you develop enough to run the file `python3 index.py`.
For production to run `index.py`, is better to use the `supervisor` and `nginx`.
Settings supervisor in `/etc`:
```python
[program:name]
command=python3 index.py
directory=/path/to/your/project
user=nobody
autorestart=true
redirect_stderr=true
```
Settings nginx in `/etc` together with proxy websocket::
```nginx
server {
server_name aio.dev;
location / {
proxy_pass http://127.0.0.1:8080;
}
location /ws {
proxy_pass http://127.0.0.1:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
```

#Routes

Example route in file `routes.py`::
```python
from libs.game.game import *
from core.union import route

route('GET', '/ws', ws, 'ws' )
```
#Templates

In framework integrated `jinja2`. Templates are always in the `templ` folder.

To call the template function `templ` and pass it the template name. If the template is in some sort of module,
the call looks like this `libs.modul_name.templ_name`.

If the template is in the root of the project in the templ folder, then simply write his name.

Example:
```python
def page(request):
return templ('index', request, {'key':'val'} )
```

#Websockets

The websocket to create games and chat very easy to use.

The first is the need to call route with the template to draw the route and chat with the handler for chat:

```python
route('GET', '/ws', ws, 'ws' )
route('GET', '/wsh', ws_handler, 'ws_handler' )
```
These routes work you can see an example.

The second is the functions themselves.
Function for render chat page:
```python
@asyncio.coroutine
def ws(request):
return templ('libs.app:chat', request, {} )
```
Function handler chat:

```python
@asyncio.coroutine
def ws_handler(request):
ws = web.WebSocketResponse()
ws.start(request)
while True:
msg = yield from ws.receive()
if msg.tp == MsgType.text:
if msg.data == 'close':
yield from ws.close()
else:
ws.send_str(msg.data + '/answer')
elif msg.tp == aiohttp.MsgType.close:
print('websocket connection closed')
return ws
```

#Database

To write the database query you need to `request.db`
and then as usual.

```python
@asyncio.coroutine
def test_db(request):
# save doc
request.db.doc.save({"_id":"test", "status":"success"})
# find doc
val = request.db.doc.find_one({"_id":"test"})
return templ('apps.app:db_test', request, {'key':val})
```

#Static files

Static files it is better to entrust `nginx` but `tao1` able return files.

All files must be located in the folder static.

If they are the root of the project then the path will be like this `/static/file_name.pg`.
If the files are in a certain module, then the path like this `/static/module_name/file_name.jpg`.

#Caching

Create cache for function 5 second, the first parameter - name::

```python
@cache("main_page", expire=5)
@asyncio.coroutine
def page(request):
return templ('index', request, {'key':'val'} )
```
