# serverish - helpers for server alike projects
[![CI](https://github.com/AkondLab/serverish/actions/workflows/test-ci.yml/badge.svg)](https://github.com/AkondLab/serverish/actions/workflows/test-ci.yml)

## Features
* Component management
* Singletons
* Connections management and diagnostics
* NATS based Messenger
* Live documents - auto-updating configuration from NATS

See [`doc` directory](doc/) for more documentation.

## Optional (extras) dependencies
The following extras are available:
* `messenger` - for using NATS based Messenger. Will install `nats-py` package.
* `dns` - for using `aiodns` DNS resolver for connection status diagnostics, it's extracted as an extra dependency because it's not available on all platforms.

In order to use Messenger, you have to add extra 'messenger' to your `project.toml` serveris dependency, e.g.:
```toml
serverish = {git="https://github.com/AkondLab/serverish.git", extras=["messenger"], branch="master"}
```
or specify dpendency with extras in the `pip` convention: `serverish[messenger]`.
this will install `nats-py` package.

## Plans
- Decorators `@messenger.sub(subject)` (Web framework style)
- Progress with automatic increment for known durations e.g. `pro_pub.update(completed=1, when=+20)`
- Pytest fixtures for NATS on CI
