Angular

In this guide you will learn how to use the hanko-elements web components to add authentication and a user profile to your Angular application.

Install dependencies

Install the @teamhanko/hanko-elements package:

npm install @teamhanko/hanko-elements

Define custom elements schema

Angular requires you to explicitly declare that you are using custom elements inside your Angular modules, otherwise it will fail during build complaining about unknown elements. To do so, import the CUSTOM_ELEMENTS_SCHEMA, and add it to the schemas in your module:

app.module.ts
import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';

@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule
],
providers: [],
bootstrap: [AppComponent],
schemas: [CUSTOM_ELEMENTS_SCHEMA]
})
export class AppModule { }

Add <hanko-auth> component

To provide a login interface in your app, use the <hanko-auth> web component. To do so, first import the register function from @teamhanko/hanko-elements in your Angular component. Then call register to register the <hanko-auth> element with the browser's CustomElementRegistry and use the element in your component template.

info

When adding the <hanko-auth> element to your template you must provide the URL of the Hanko API via the api attribute. If you are using Hanko Cloud, you can find the API URL on your project dashboard. If you are self-hosting you need to provide the URL of your running Hanko backend.

<hanko-auth [api]="hankoApi" />

Define login callbacks

The <hanko-auth> element dispatches a custom hankoAuthSuccess event on successful login. React to this event to redirect your users to protected pages in your application, e.g. a user profile page.

You can use Angular's event binding mechanism and supply a callback function that is defined in your component class directly on the <hanko-auth> element:

<hanko-auth
(hankoAuthSuccess)="redirectAfterLogin()"
[api]="hankoApi" />

Add <hanko-profile> component

To provide a page where users can manage their email addresses, password and passkeys, use the <hanko-profile> web component. Just as with the <hanko-auth> component, import the register function from @teamhanko/hanko-elements in your Angular component. Then call register to register the <hanko-profile> element with the browser's CustomElementRegistry and use the element in your component template.

info

When adding the <hanko-profile> element to your template you must provide the URL of the Hanko API via the api attribute. If you are using Hanko Cloud, you can find the API URL on your project dashboard. If you are self-hosting you need to provide the URL of your running Hanko backend.

  <hanko-profile [api]="hankoApi" />

Customize component styles

The styles of the hanko-auth and hanko-profile elements can be customized using CSS variables and parts. See our guide on customization here.
