Update Title and Meta Tags from Routes Data

Declare SEO data for each route recommended to use NgxSeo interface to prevent problems.

...
import { NgxSeo } from '@avivharuzi/ngx-seo';

...

const SEO_HOME: NgxSeo = {
  title: 'home page',
  meta: {
    description: 'home page description',
  },
};

const SEO_ABOUT: NgxSeo = {
  title: 'about page',
  meta: {
    description: 'about page description',
  },
};

const routes: Routes = [
  { path: '', component: HomeComponent, data: { seo: SEO_HOME } },

];

You can also specify custom meta tags by providing array of MetaDefinition.

const SEO_SPECIAL: NgxSeo = {
  meta: {
    customTags: {
      mySpecial: {
        name: 'mySpecial',
        content: 'mySpecial content :P',
      },
    },
  },
};

const routes: Routes = [
  { path: 'special', component: SpecialComponent, data: { seo: SEO_SPECIAL } },
];

export class MoiveDetailComponent implements OnInit {
  movie: Movie;

  constructor(
    private movieService: MovieService,
    private ngxSeoService: NgxSeoService,
  ) {}

  ngOnInit(): void {
    this.movieService.getDetails(1).subscribe(movie => {
      this.movie = movie;

      this.ngxSeoService.setSeo({
        title: movie.title,
