Project description

serverish - helpers for server alike projects

CI

Features

  • Component management
  • Singletons
  • Connections management and diagnostics
  • NATS based Messenger

See doc directory for more documentation.

Optional (extras) dependencies

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.:

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.
