Angular - Update html attribute in root index.html

I have following content in my index.html

<!doctype html>
<html dir="ltr" lang="en">
    <head>
        <meta charset="utf-8">
        <title>Halls Gate</title>
        <base href="/">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <link rel="icon" type="image/png" href="assets/img/favicon.png">
        <link href="https://fonts.googleapis.com/css?family=Montserrat:300,400,500,600,700" rel="stylesheet">
        <link href="https://fonts.googleapis.com/css?family=Istok+Web" rel="stylesheet">
    </head>
    <body>
        <app-root></app-root>
    </body>
</html>

I want to update dir and lang attribute in html element from a component <html dir="ltr" lang="en"> based on the language selected.

Is there a way to go about this in Angular?

Thank you.

Solution

  • I think, it can be changed simply...

    https://stackblitz.com/edit/angular-ih2drk?file=src%2Fapp%2Fapp.component.ts

    import { Component, Renderer2 } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  name = 'Angular 6';
  constructor(private renderer: Renderer2) {
    this.renderer.setAttribute(document.querySelector('html'), 'lang', 'tr');
  }
}
