Observables as a Standard: Streams everywhere

@ManekiNekko

We are all heavy Observables developers

Angular

RxJS

NgRx

@ManekiNekko

Unify across libraries

Benefits of Standardisation

Ship less code to the browser

Fewer polyfills to maintain

Useful Out Of The Box

map()
filter()
reduce()

@ManekiNekko

Process DOM events in a standard way

document
    .querySelector("#img")
    .on("load")
    .subscribe(e => { ... })

@ManekiNekko

Status & Roadmap

Ivy:

Angular's new Renderer

@ManekiNekko

Goals

Smaller Size

Simpler Debugging

Faster Compilation

Non-Breaking Changes

import { Component } from '@angular/core';
@Component({
 selector: 'app-root',
 template: `
 <h1>
   app, {{title}}
 </h1>
 `,
 styleUrls: ['./app.component.css']
})
export class AppComponent {
 title = 'works!';
}

import * as core from '@angular/core';
export class AppComponent  {
  static ngComponentDef = core.ɵdefineComponent({
    type: AppComponent,
    tag: 'app-root',
    template: template: (rf: core.ɵRenderFlags, ctx: ManualComponent) => {
      if (rf & 1) {
          core.ɵE(0, 'h1');
          core.ɵT(1, 'app, ');
          core.ɵT(2);
          core.ɵe();
      }
      if (rf & 2) {
          core.ɵt(2, ctx.title);
      }
    },
    factory: () => new AppComponent()
  })
}

Roadmap

1. Hello World <5kB 

2. API Compatible

3. Smaller bundle size

4. Internal Validation (by Google teams)

5. Public Release

6. Default in v8
