Install the @firebase-oss/ui-react package:

npm install @firebase-oss/ui-react@beta

Alongside your Firebase configuration, import the initializeUI function and pass your configured Firebase App instance:

import { initializeApp } from 'firebase/app';
import { initializeUI } from '@firebase-oss/ui-core';

const app = initializeApp({ ... });

const ui = initializeUI({
  app,
});

Once configured, provide the ui instance to your application by wrapping it within the FirebaseUIProvider component:

import { FirebaseUIProvider } from '@firebase-oss/ui-react';

function App() {
  return (
    <FirebaseUIProvider ui={ui}>
      ...
    </FirebaseUIProvider>
  );
}

Ensure your application includes the bundled styles for Firebase UI (see styling for additional info).

@import "@firebase-oss/ui-styles/dist.min.css";
/* Or, if you use tailwind */
@import "@firebase-oss/ui-styles/tailwind";

That's it 🎉 You can now import components and start building:

import { SignInAuthScreen } from '@firebase-oss/ui-react';

export function MySignInPage() {
  return (
    <>
      <header>Welcome</header>
      <SignInAuthScreen onSignIn={() => { ... }} />
    </>
  )
}

View the reference API for a full list of components.

Firstly, ensure you have installed and setup Shadcn in your project.

Once configured, add the @firebase registry to your components.json file:

{
  ...
  "registries": {
    "@firebase": "https://firebaseopensource.com/r/{name}.json"
  }
}

Next, add a Firebase UI component from the registry, e.g.

npx shadcn@latest add @firebase/sign-in-auth-screen

This will automatically install any required dependencies.

Alongside your Firebase configuration, import the initializeUI function and pass your configured Firebase App instance:

import { initializeApp } from 'firebase/app';
import { initializeUI } from '@firebase-oss/ui-core';

const app = initializeApp({ ... });

const ui = initializeUI({
  app,
});

Once configured, provide the ui instance to your application by wrapping it within the FirebaseUIProvider component:

import { FirebaseUIProvider } from '@firebase-oss/ui-react';

function App() {
  return (
    <FirebaseUIProvider ui={ui}>
      ...
    </FirebaseUIProvider>
  );
}

That's it 🎉 You can now import components and start building:

import { SignInAuthScreen } from '@/components/sign-in-auth-screen';

export function MySignInPage() {
  return (
    <>
      <header>Welcome</header>
      <SignInAuthScreen onSignIn={() => { ... }} />
    </>
  )
}

View the reference API for a full list of components.

The Angular project requires that AngularFire is setup and configured before using Firebase UI.

Once you have provided the Firebase App instance to your application using provideFirebaseApp, install the Firebase UI for Angular package:

npm install @firebase-oss/ui-angular@beta

Alongside your existing providers, add the provideFirebaseUI provider, returning a new Firebase UI instance via initializeUI:

import { provideFirebaseApp, initializeApp } from '@angular/fire/app';
import { initializeUI } from '@firebase-oss/ui-core';

export const appConfig: ApplicationConfig = {
  providers: [
    provideFirebaseApp(() => initializeApp({ ... })),
    provideFirebaseUI((apps) => initializeUI({ app: apps[0] })),
  ]
};

Ensure your application includes the bundled styles for Firebase UI (see styling for additional info).

@import "@firebase-oss/ui-styles/dist.min.css";
/* Or for tailwind users */
@import "@firebase-oss/ui-styles/tailwind";

That's it 🎉 You can now import components and start building:

import { Component } from "@angular/core";
import { SignInAuthScreenComponent } from "@firebase-oss/ui-angular";

@Component({
  selector: "sign-in-route",
  standalone: true,
  imports: [CommonModule, SignInAuthScreenComponent],
  template: `
    <header>Sign In</header>
    <fui-sign-in-auth-screen (signIn)="onSignIn($event)" />
  `,
})
export class SignInRoute {
  onSignIn(user: User) {
    // ...
  }
}
