Different ways to set tags and other SEO properties.

Set defaults

You can set defaults and other options for the module by using the forRoot() option in the import section:

API

Name	Default value	Description
useTitleSuffix: boolean;	false	Add an optional title suffix.
extendTitle: boolean;	false	Append parent page titles (when using router context).
titleDelimiter: string;	`'	'`
defaults: Context;	{}	Default values for the meta tags. Have a look at the list down below for an overview of possible tags.
routerContext: boolean;	true	Listen for meta data on the route changes.

Example

@NgModule({
    imports: [
        ContextModule.forRoot({
            useTitleSuffix: true,
            extendTitle: true,
            titleDelimiter: ' | ',
            defaults: {
                titleSuffix: 'Context Module',
            },
            routerContext: true,
        }),
    ]
})

Set tags on routes

You can set tags on routes using the data property. The ContextService will subscribe to the router and pick up these tags automatically.

export const CONTEXT_EXAMPLES_ROUTES: Routes = [
    {
        path: '',
        component: ContextDemoPageComponent,
        pathMatch: 'full',
        data: {
            meta: {
                page: 'Context example page',
                title: 'Context',
                description: 'Description of the context example page',
                metatags: 'Antwerp UI, Angular, context',
            },
        },
    },
];

Set tags on routes

You can set tags manually in your components using the loadContext method as well. This is useful for async data or generic routes.

import { ContextService } from '@acpaas-ui/ngx-context';

@Component({
    providers: [
        ContextService,
    ],
})

export class ContextDemoPageComponent {
    constructor(private contextService: ContextService) {}

    public setTitle() {
        this.contextService.updateContext({
            title: 'New context example title',
        });
    }
}

<button class="a-button" (click)="setTitle()">Set title</button>
