A tool for updating meta tags in an Angular application.
npm install --save ngmeta
First you'll need to pass the NGMeta service as a providers in your NgModule.
import { NGMeta } from 'ngmeta';
...
@NgModule({
providers: [
NGMeta
],
bootstrap: [
AppComponent
]
})
export class AppModule { }
To dynamically edit this data whenever a page is loaded. Import NGMeta into your component, then inside of your constructor pass in the NGMeta service as an argument...
import { NGMeta } from 'ngmeta';
...
export class HomePage {
constructor(private _ngmeta: NGMeta) {}
}
Then in the component we can call our NGMeta service this._ngmeta.setHead(). This takes an object of the new values for the tags you want. Below we change the title and description data on a page.
this._ngmeta.setHead({
title: 'Google',
meta : [
{attribute: 'name', type: 'description', content: 'Search the world\'s information, including webpages, images, videos and more. Google has many special features to help you find exactly what you\'re looking for.'}
]
});
Now our head data will display
<head>
<title>Google</title>
<meta name='description' content='Search the world's information, including webpages, images, videos and more. Google has many special features to help you find exactly what you're looking for.'>
</head>
Full documentation for the NGMeta service is available here.
For typing you can take two of ther interfaces that NGMeta uses by importing them with
import { TagData, MetaData } from 'ngmeta';
interface MetaData {
type: string;
content: string;
attribute?: string;
}
interface TagData {
title?: string;
name?: MetaData[];
property?: MetaData[];
meta?: MetaData[];
canonical?: string;
}
| Function | Description |
|---|---|
set canonical(canonicalURL: string) | Sets canonical tag for page, to call this._ngmeta.canonical = 'https://www.google.com';. |
public createMeta(metaData: MetaData) | Creates HTML for a <meta> tag of any attribute. |
get scrollEnabled() | Returns boolean value if scroll to top is enabled, to call let scrollEnabled: boolean = this._ngmeta.scrollEnabled;. |
set scrollEnabled(scroll: boolean) | Sets wether <body></body> should scroll to top on route change, to call this._ngmeta.scrollEnabled = true;. |
public setHead(tagData: TagData) | Set function setting all <head></head> metadata. |
get title() | Returns string value of current page's title, to call let title: string = this._ngmeta.title;. |
set title(title: string) | Sets <title></title> tag for page, to call this._ngmeta.title = 'Google';. |
