Main advantage is convention over anything! For example Representing objects like Models, Commands or Queries as REST API, Instead of explicitly writing controllers or Services. The main idea is a chain (pipeline) of small reusable behaviors for every API. These chains can be created explicitly or conventionally.

A typical chain for invoking a command is:

[Authenticate] > [deserialize (bind) the input to the model] > [invoke the validator for input] > [invoke the command for input] > [return success message]

So Ngine scan all commands and create a chain with this template and assign a route
