Update HTML meta tags for title, description and others automatically based on the route in your Angular app.

ng2-meta v5.0.0+ requires Angular 6. On Angular 5 or lower, use ng2-meta v4.0.0 (

npm install [email protected]

For the AngularJS (1.x) module, check out ngMeta

Getting started


To install this library, run:

$ npm install ng2-meta --save

Modify routes

Add meta tags and

to routes. By default,
values are duplicated for
, so there's no need to add them separately.

import { MetaGuard } from 'ng2-meta';

const routes: Routes = [ { path: 'home', component: HomeComponent, canActivate: [MetaGuard], data: { meta: { title: 'Home page', description: 'Description of the home page' } } }, { path: 'dashboard', component: DashboardComponent, canActivate: [MetaGuard], data: { meta: { title: 'Dashboard', description: 'Description of the dashboard page', 'og:image': 'http://example.com/dashboard-image.png' } } } ];

Import MetaModule

import { MetaModule } from 'ng2-meta';

  declarations: [
  imports: [
  bootstrap: [AppComponent]

Update AppComponent

import { MetaService } from 'ng2-meta';

export class AppComponent {
  constructor(private metaService: MetaService) {}

You're all set! ng2-meta will update the meta tags whenever the route changes.


Set defaults

Set default values for tags. These values are used when routes without

meta: {}
information are encountered. ```typescript import { MetaConfig, MetaService } from 'ng2-meta';

const metaConfig: MetaConfig = { //Append a title suffix such as a site name to all titles //Defaults to false useTitleSuffix: true, defaults: { title: 'Default title for pages without meta in their route', titleSuffix: ' | Site Name', 'og:image': 'http://example.com/default-image.png', 'any other': 'arbitrary tag can be used' } };

@NgModule({ declarations: [ AppComponent, ... ], imports: [ ..., MetaModule.forRoot(metaConfig) ], bootstrap: [AppComponent] })

### Change meta tags programmatically
import { Component, OnInit } from '@angular/core';

class ProductComponent implements OnInit { ... constructor(private metaService: MetaService) {}

ngOnInit() { this.product = //HTTP GET for product in catalogue this.metaService.setTitle('Product page for '+this.product.name); this.metaService.setTag('og:image',this.product.imageURL); } }

Define fallback meta content in HTML

While Google executes Javascript and extracts meta tags set by ng2-meta, many bots (like Facebook and Twitter) do not execute Javascript. Consider defining fallback meta tags in your HTML for such bots. The fallback content is overridden by ng2-meta in Javascript-enabled environments.

<meta name="title" content="Website Name">
<meta name="og:title" content="Website Name">
<meta name="description" content="General description of your site">
<meta name="og:description" content="General description of your site">
<meta name="og:image" content="http://example.com/fallback-image.png">
