NgRX Auto-Entity

Automatic entities for @ngrx! Simplifying reactive state!

What is it?

NgRX Auto-Entity aims to provide a seamless means of dealing with standard entity actions and effects with minimal repetitive code requirements, while preserving the fundamental nature of NgRX itself. This library is not a replacement for or alternative to NgRX. It works within the standard paradigm that NgRX has set forth, making use of actions, reducers & effects like any other NgRX application.

What Auto-Entity does do is provide a set of ready-made actions, selectors, effects & a core metareducer for handling all of the standard CRUD functionality for entities, so you neither have to write nor generate any of that code yourself. Auto-Entity supports implementing applications with recommended best practices, including good action hygiene. Auto-Entity also generates pre-fabricated facades around NgRx and the store/state, providing a cohesive, logical and simplified API into your state for those who prefer facades. Auto-Entity presents a flexible framework that you may use in its entirety for all of your entity needs, or use piecemeal as necessary in order to achieve your specific goals.

While it is not required and Auto-Entity is an entirely independent library that solely depends on Angular and NgRX, Auto-Entity manages state in a manner that is compatible with @ngrx/entity as well, in the event you wish to utilize some of the utilities from that library in your own custom reducers.

Dependencies

NgRx Auto-Entity is compatible with the following versions.

Installation

Install @briebug/ngrx-auto-entity from npm:

• npm install @briebug/ngrx-auto-entity,
• yarn add @briebug/ngrx-auto-entity, or
• pnpm add @briebug/ngrx-auto-entity

If you have not already, install the required peer dependencies as well:

• npm install @ngrx/{effects,store,store-devtools},
• yarn add @ngrx/{effects,store,store-devtools}, or
• pnpm add @ngrx/{effects,store,store-devtools}
