## Getting Started

### Installation

Using [npm](https://npmjs.org) in your project directory run the following command:

```sh

npm install @auth0/auth0-spa-js

```

From the CDN:

```html

```

### Configure Auth0

Create a **Single Page Application** in the [Auth0 Dashboard](https://manage.auth0.com/#/applications).

> **If you're using an existing application**, verify that you have configured the following settings in your Single Page Application:

>

> - Click on the "Settings" tab of your application's page.

> - Scroll down and click on the "Show Advanced Settings" link.

> - Under "Advanced Settings", click on the "OAuth" tab.

> - Ensure that "JsonWebToken Signature Algorithm" is set to `RS256` and that "OIDC Conformant" is enabled.

Next, configure the following URLs for your application under the "Application URIs" section of the "Settings" page:

- **Allowed Callback URLs**: `http://localhost:3000`

- **Allowed Logout URLs**: `http://localhost:3000`

- **Allowed Web Origins**: `http://localhost:3000`

> These URLs should reflect the origins that your application is running on. **Allowed Callback URLs** may also include a path, depending on where you're handling the callback (see below).

Take note of the **Client ID** and **Domain** values under the "Basic Information" section. You'll need these values in the next step.

### Configure the SDK

Create an `Auth0Client` instance before rendering or initializing your application. You should only have one instance of the client.

```js

import { createAuth0Client } from '@auth0/auth0-spa-js';

//with async/await

const auth0 = await createAuth0Client({

  domain: '',

  clientId: '',

  authorizationParams: {

    redirect_uri: ''

  }

});

//or, you can just instantiate the client on its own

import { Auth0Client } from '@auth0/auth0-spa-js';

const auth0 = new Auth0Client({

  domain: '',

  clientId: '',

  authorizationParams: {

    redirect_uri: ''

  }

});

//if you do this, you'll need to check the session yourself

try {

  await auth0.getTokenSilently();

} catch (error) {

  if (error.error !== 'login_required') {

    throw error;

  }

}

```

### Logging In

You can then use login using the `Auth0Client` instance you created:

```html

Click to Login

```

```js

//redirect to the Universal Login Page

document.getElementById('login').addEventListener('click', async () => {

  await auth0.loginWithRedirect();

});

//in your callback route ()

window.addEventListener('load', async () => {

  const redirectResult = await auth0.handleRedirectCallback();

  //logged in. you can get the user profile like this:

  const user = await auth0.getUser();

  console.log(user);

});

```
