How to setup oAuth in the Next.js Supabase Lite Starter

For oAuth - you can enable multiple providers. For example, you can enable Google and Facebook authentication at the same time by adding the providers to the auth.providers.oAuth array in the configuration file at src/configuration.ts.

You must configure the oAuth providers in three places:

1. Supabase - you need to setup an oAuth application in Supabase.
2. Provider - you need to setup an oAuth application in the provider (for example, Google Auth)
3. Makerkit Configuration - you need to add the provider to the auth.providers.oAuth array in the configuration file at src/configuration.ts.

Below is an example of how to enable Google and Facebook authentication:

providers: {
 emailPassword: false,
 phoneNumber: false,
 emailLink: false,
 oAuth: ['google', 'facebook'] as Provider[]
},

The interface Provider is very important as it tells Makerkit which OAuth provider to use. You can find the list of supported OAuth providers here.

By default, Makerkit provides logos for the most famous oAuth providers, but not all of them. To add a logo for an oAuth provider, please update the src/core/ui/AuthProviderLogo.tsx file.

You will provide a string or a React node for the logo by specifying the provider name as the key of the object.

function getOAuthProviderLogos(): Record<string, string | React.ReactNode> {
 return {
   password: <AtSymbolIcon className={'h-[22px] w-[22px]'} />,
   phone: <DevicePhoneMobileIcon className={'h-[22px] w-[22px]'} />,
   google: '/assets/images/google.webp',
   facebook: '/assets/images/facebook.webp',
   twitter: '/assets/images/twitter.webp',
   github: '/assets/images/github.webp',
   microsoft: '/assets/images/microsoft.webp',
   apple: '/assets/images/apple.webp',
 };
}

How to Setup an oAuth Provider

Most of the setup is done in two places:

1. Supabase - you need to setup an oAuth application in Supabase.
2. Provider - you need to setup an oAuth application in the provider (for example, Google Auth)
