So, let's start?

<webapps/>                    are evolving

and we need to be up-to-date

<page-container>
</page-container>
<component1 />
<component2>
</component2>
<component3 />

Layout container

small scope

boundaries

plug-and-play

Everything is a component

bundle
test
publish
lint

Opinions ?

reporter
dev server
types
coverage

npm install -g @angular/cli
// Installing Angular CLI
ng new my-app
// Creating a new Angular App
ng serve
// Starting local server

Schematics 

...will always help you

# Adding inline style and inline template

  "defaultProject": "my-app",
  "schematics": {
    "@schematics/angular": {
      "component": {

      }
    }
  }
  ...
}

Retrieve data         using resolver

it's a fight to be continued...

// create a resolver

export class ListingItemResolver implements Resolve<ListingItem> {
  constructor(
    private service: ListingItemService
  ) {}

  resolve(route: ActivatedRouteSnapshot) {
    const id = route.paramMap.get('id');

    return this.service
        .getListingItem(id);
  }
}

Item resolver

// Adding `ListingItemResolver` 
// resolver in your route

const routes: Routes = [{
  path: ':id',
  component: ListingItemDetailContainerComponent,
  resolve: { item: ListingItemResolver },
}];

Angular Universal

or: Server-Side Render with style 😎

ng g universal 
  --clientProject my-app
// Configuring Angular universal
ng build my-app --prod
// Build app in prod mode
ng run my-app:server:production
// Run server in prod mode

tsconfig.server.json

main.server.ts

app.server.module.ts

// Create a service to handle
// all the changes in the main tags
// `metatags`, `title`, etc

export class LayoutService {

  constructor(private meta: Meta, private title: Title) { }

  public setMetaData(config) {
    this.title.setTitle('Page Title');

    const tags = [
      { name: 'description', content: 'Description' },
      { name: 'theme-color', content: '#333' },
      { property: 'og:title', content: title },
      { property: 'og:description', content: 'Description' },
      { property: 'og:image', content: '/image.png' },
    ];

    tags.forEach(tag => this.meta.updateTag(tag));
  }
}

Server-side

or

Client-side

🥊 🥊 🥊

Service Workers

PWA in the right way ✅

ng add @angular/pwa
// PWA support out of the box

manifest.json

ngsw-config.json
