Bonfire

Writen by Tzach bonfil. github

Bonfire is open source decorators utils for angular.

• Make change detection easy
• Makes Observable for you

You can make your code cleaner and simpler with adding just 2 decorators to your code. We know that angular change detection is not simple if you want it to be officiant. So I made Bonfire. Simple solution to hard problem.

Now there is no use to call the change detection!

Installation

Bonfire requires Node.js v4+ to run.

$ npm i @intelligo.ai/bonfire

The Tools

See Examples Below:

Tools	What it does?	How to use?
(1) ReRenderOnChange	The decorator on the component is actually what causes the other decorators to use change detection	Put it on the top of the component and make sure the component have change detection injected
(2) SetChecker	Put it on a property we want to trigger re-render only if it changed	Just put it on the property
(3) WithObservable	Generate a behavior subject (Observable), Which emit values that stored in the original property (You don't need to maintain it at all! Just use it)	Put in on the original property and next to it write the same property name with '$', it will store automatically

Where to use

Before you use it, make sure you inject the change detection to your component!

import { ReRenderOnChange, SetChecker, WithObservable } from '@intelligo.ai/bonfire';

@ReRenderOnChange() // <== (1)
@Component({
  selector: 'my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.scss'],
  changeDetection: ChangeDetectionStrategy.OnPush // <== IMPORTANT
})

export class MyComponent {

  @SetChecker() group: ISomeInterface = {
   test: [
     {
       name: 'Hello',
       age: 30
     }
    ]
  }; // <== (2)

  @WithObservable() showLoader = false; showLoader$: BehaviorSubject<boolean>; // <== (3)

  constructor(
    private cd: ChangeDetectorRef // <== MOST IMPORTANT
  ) {

    setTimeout(() => {
      // This won't trigger change detection unless you are using SetChecker :-)
      this.groups.test[0].name = 'World'
    },5000)

  }
}

Dependencies

Bonfire uses a number of open source projects to work properly:

• Angular - Platform for building mobile and desktop web applications.
• Rxjs - Reactive extensions library for javascript.
• uuid - Simple, fast generation of RFC4122 UUIDS.
