ao-concepts core module

This module provides the following functionalities:

• a http webserver, based on Gin Web Framework
• a basic http client
• a websocket server that uses the same api as the http webserver. It uses a radix tree router
• a websocket client that uses the same api as the websocket server. It uses a radix tree router
• a tiny service container that uses reflection
• some useful application helpers:
  • logging
  • reading data from files into structs and writing data from structs into files (primarily for configuration purposes)
  • database acces and transactions (based on gorm)
  • struct reflection
  • struct validation

Information

The ao-concepts ecosystem is still under active development and therefore the API of this module may have breaking changes until there is a first stable release.

If you are interested in contributing to this project, feel free to open a issue to discus a new feature, enhancement or improvement. If you found a bug or security vulnerability in this package, please start a issue, or open a PR against master.
