# Social Authentication

Social authentication block for Vue Single Page Applications

## Files

- `components/`
  - `login-form.vue`

External registry dependencies: button, card.

Full source: https://supabase.com/library/r/social-auth-vue.json

Note: The block is using GitHub provider by default, but can be easily switched by changing a single
parameter.

## Installation

### Set up the Supabase client

This block requires a Supabase client for Vue. If your project already has one, reuse it and update the block's imports to match your client. Otherwise, install the client:

Install this block:

```bash
npx shadcn-vue@latest add https://supabase.com/library/r/supabase-client-vue.json
```

Configure the environment variables described in the [Vue client guide](https://supabase.com/library/docs/vue/client.md#getting-started) before using the block.

### Install the block

Install this block:

```bash
npx shadcn-vue@latest add https://supabase.com/library/r/social-auth-vue.json
```

## Usage

Once you install the block in your Vue project, you'll get all the necessary pages and components to set up a social authentication flow.

### Getting started

After installing the block, you'll have the following environment variables in your `.env.local` file:

```env
VITE_SUPABASE_URL=
VITE_SUPABASE_PUBLISHABLE_KEY=
```

- If you're using supabase.com, you can find these values in the [Connect modal](https://supabase.com/dashboard/project/_?showConnect=true\&connectTab=frameworks\&framework=react\&using=vite\&with=supabasejs) under App Frameworks or in your project's [API settings](https://supabase.com/dashboard/project/_/settings/api).

- If you're using a local instance of Supabase, you can find these values by running `supabase start` or `supabase status` (if you already have it running).

### Setting up third party providers

We support a wide variety of social providers that you can use to integrate with your application. The full list is available [here](https://supabase.com/docs/guides/auth/social-sign-in).
This block uses the implicit flow with GitHub as the provider. To switch providers, just update the `provider` field in the `supabase.auth.signInWithOAuth` call. Enable the provider you want to use under [Auth Providers](https://supabase.com/dashboard/project/_/auth/providers) in the Supabase Dashboard and add the necessary credentials.

### Setting up routes and redirect URLs

1. Set the site URL in the [URL Configuration](https://supabase.com/dashboard/project/_/auth/url-configuration) settings in the Supabase Dashboard.
2. Update the redirect paths in `login-form.vue` to point to your app’s logged-in routes. Our examples use `/protected`, but you can set this to whatever fits your app.

### Combining social auth with password-based auth

If you want to combine this block with the password-based auth, you need to copy the `handleSocialLogin` function into the password-based `login-form.vue` component and bind it to a button.
