It certainly has more documentation 13 | and features than this one. 14 | 15 | # Old, Third Party A2-Firebase Library 16 | 17 | This third-party library existed because: 18 | 19 | * I started well before the official library. 20 | * I was able to get applications up and running with it. 21 | * It has a considerably more minimal approach, contrasting the 22 | "wrap outside things in Angular thing" 23 | approach used by angularfire2. 24 | 25 | ## Introduction 26 | 27 | An application should be able to consume data *without* caring 28 | about the on() Firebase API, Firebase events, or the 29 | object-as-pseudo-array convention. 30 | 31 | The library currently includes: 32 | 33 | * Firebase Observable object, a very straightforward implementation. 34 | * Firebase Observable array, which understands the pattern of events emitted 35 | by Firebase and produces an observable of the resulting array. 36 | 37 | Many areas are still under consideration and development: 38 | 39 | * Writing to Firebase. 40 | * Following references (joins) 41 | * A way to generate TS schema from Bolt schema, or vice versa. 42 | 43 | ## Demo 44 | 45 | https://github.com/OasisDigital/angular2-firebase-demo 46 | 47 | ## Why Observables? Why the async pipe? 48 | 49 | By wrapping the Firebase API behind Observables, 50 | then consuming those Observables typically via an async pipe, 51 | it should never be necessary to manually subscribe 52 | and unsubscribe the Observables, 53 | nor manually hook and unhook Firebase events. 54 | 55 | I believe that, if you find it necessary to write ngOnDestroy in a visual component, 56 | it is a sign that the component is not yet sufficienty abstracted. 57 | 58 | ## How to Consume 59 | 60 | It will generally "just work" with typescript and webpack. 61 | Other combinations might work, but still need attention. 62 | 63 | As far as I can tell, TypeScript with NPM modules is still a topic of much 64 | discussion and work. This library does the following, 65 | it appears to be the preferred approach: 66 | 67 | * Leave the TypeScript code in the repository, don't ship it in the NPM package 68 | * Ship ES5 code with .d.ts 69 | * Also ship ES6 code with .d.ts, to enable downstream "tree shaking". 70 | 71 | Older versions of this library included typings for Firebase; 72 | the "typings" and related tooling have made that obsolete. 73 | Use typings or other means to obtain the Firebase .d.ts file, 74 | and include it in your project. 75 | 76 | For examples of working tsconfig and typings, see the demo: 77 | 78 | https://github.com/OasisDigital/angular2-firebase-demo 79 | 80 | 81 | Kyle Cordes 82 | http://kylecordes.com 83 | -------------------------------------------------------------------------------- /ts/ngWhen.ts: -------------------------------------------------------------------------------- 1 | // Angular 2 Toolkit - ngWhen 2 | // Copyright 2015-2016 Oasis Digital - http://oasisdigital.com 3 | // written by Kyle Cordes - http://kylecordes.com 4 | // started November 2015 5 | 6 | import {Directive} from '@angular/core'; 7 | import {DoCheck, ChangeDetectorRef, EmbeddedViewRef} from '@angular/core'; 8 | import {ViewContainerRef, TemplateRef, ViewRef} from '@angular/core'; 9 | 10 | 11 | export class NgWhenPayload { 12 | constructor(public $implicit: any) { } 13 | } 14 | 15 | /** 16 | * TODO document this like NgIf and NgFor, 17 | * The following is some text from the docs for those things, here for reference. 18 | * 19 | * Removes or recreates a portion of the DOM tree based on an {expression}. 20 | * 21 | * If the expression assigned to `ng-if` evaluates to a false value then the element 22 | * is removed from the DOM, otherwise a clone of the element is reinserted into the DOM. 23 | * 24 | * ### Example ([live demo](http://plnkr.co/edit/fe0kgemFBtmQOY31b4tw?p=preview)): 25 | * 26 | * ``` 27 | *
