NgRX Auto-Entity

Automatic entities for @ngrx! Simplifying reactive state!

NOTE: NgRX Auto-Entity is currently a beta library. It is in flux as we continue to refine and enhance it's functionality, identify and eliminate bugs, optimize it's performance. If you find any errors in this documentation, or bugs within the library, please let us know!

APOLOGIES: For those using NgRx Auto-Entity, we apologize for issues with the recent v0.3.0 release! We used an npm module, uuidv4, and back in november our usage of it was working. It appears as though that library was changed fairly significantly since then, with the default import removed. That lead to issues for some people, depending on the version of uuidv4 they installed/had installed. We have dropped uuidv4 and are now using a small, fast built-in function instead in v0.3.1 and onward, which should resolve the issues. Again, we apologize for the inconvenience!

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, generic actions for handling all of the standard CRUD operations for entities, so you neither have to write nor generate any of that code yourself. Auto-Entity generates pre-fabricated facades around NgRx and the store/state, providing a cohesive, logical and simplified API into your state. 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 currently depends on Angular 8+, NgRx 8+ and RxJs 6.

Installation

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

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

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

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