Installation

1. Install the package

$ npm install angular-router-meta --save

2. Import RouterMetaModule from node_modules/angular-router-meta folder

import { RouterMetaModule } from 'angular-router-meta';

Add imported module to the imports section in NgModule decorator

@NgModule({
  .
  .
  .
  imports: [
    :
    RouterMetaModule.forRoot()
  ]
})

NOTE: forRoot() method isn't optional. The module won't work if you do not call this method

3. Inject service in AppComponent constructor

import { Component } from '@angular/core';
import { RouterMetaService } from 'angular-router-meta';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  constructor(
    private routerMeta: RouterMetaService
  ){ }
}

Usage

Add an array of meta tags inside the data property in your routes constant

export const appRoutes: Routes = [
  {
    path: 'somepath',
    loadChildren: 'modules/some/some.module#SomeModule',
    data: {
        meta: [
            {
                name: 'my_name',
                content: 'the_name',
                charset: 'utf-8',
                property: 'some_property'
            },
            {
                name: 'render:status_code',
                content: '200'
            }
        ]
    }
  }
];

Result

These settings in appRoutes constant will render the following code in head tag:

<meta name="my_name" content="the_name" charset="utf-8" property="some_property" angular-router-meta>
<meta name="render:status_code" content="200" angular-router-meta>
