```
pytest --cov
```

## Features

* Asynchronous web routes with [aiohttp](https://aiohttp.readthedocs.io/en/stable/)
* Data validation, serialization and unserialization with python [dataclasses](https://docs.python.org/3/library/dataclasses.html)
* [OpenApi](https://www.openapis.org/) v 3 auto documentation
* [SqlAlchemy](https://www.sqlalchemy.org/) expression language
* Asynchronous DB interaction with [asyncpg](https://github.com/MagicStack/asyncpg)
* Migrations with [alembic](http://alembic.zzzcomputing.com/en/latest/)
* SqlAlchemy tables as python dataclasses

## Websockets

This library provides a simple distributed websocket utility for creating
websocket remote procedure calls (RPC) and pub/sub.
```python
from aiohttp import web

from openapi.ws import Sockets

app = web.Application()
...
app['web_sockets'] = Sockets(app)
```
### RPC protocol

The RPC protocol has the following structure for incoming messages
```
{
"id": "abc",
"method": "rpc_method_name":
"payload": {
...
}
}
```
The ``id`` is used by clients to link the request with the corresponding response.
The response for an RPC call is eitrher a success
```
{
"id": "abc",
"method": "rpc_method_name":
"result": {
...
}
}
```
or error
```
{
"id": "abc",
"method": "rpc_method_name":
"error": {
...
}
}
```
### Publish/Subscribe

To subscribe to messages, one need to use the ``Subscribe`` mixin with the subscribe RPC handler.
Messages take the form:
```
{
"channel": "channel_name",
"event": "event_name":
"data": {
...
}
}
```
