Philosophy

The Acai philosophy is to provide a dry, configurable, declarative library for use with the amazon lambdas, which encourages Happy Path Programming (HPP).

Happy Path Programming is an idea in which inputs are all validated before operated on. This ensures code follows the happy path without the need for mid-level, nested exceptions and all the nasty exception handling that comes with that. The library uses layers of customizable middleware options to allow a developer to easily dictate what constitutes a valid input, without nested conditionals, try/catch blocks or other coding blocks which distract from the happy path that covers the majority of that codes intended operation.
