Authentication

Set up authentication in your app to allow users to sign in, sign up, and manage accounts securely.

Tools

Better Auth: Provides secure authentication with email/password, OAuth, and magic link support.

Setup

For Google OAuth, sign up at Google Cloud Console and copy the Client ID and Client Secret.

Update your config:

shared/config.ts

auth: {
    enablePasswordLogin: true, // Allow email/password login and registration
    enableEmailVerification: false, // Require email verification after signup
    enableMagicLink: false, // Allow passwordless login via email link

    oauthProviders: ['google'], // Enable Google OAuth

    redirectAfterSignIn: '/', // Where to redirect after successful login
    password: {
        minLength: 8,
        maxLength: 128,
        pattern: /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{8,}$/,
    },
},

Note: Add more OAuth providers (e.g., github, twitter, apple) to oauthProviders and set corresponding environment variables (e.g., OAUTH_GITHUB_CLIENT_ID, OAUTH_GITHUB_CLIENT_SECRET).

Set the following environment variables:

.env

BETTER_AUTH_SECRET="your-long-random-string"
OAUTH_GOOGLE_CLIENT_ID="your-google-client-id"
OAUTH_GOOGLE_CLIENT_SECRET="your-google-client-secret"

Usage

Email/Password: Sign in, sign up, reset password, sign out
Google OAuth: Sign in with Google account
Magic Link: Sign in via email link
Verify Setup: Use user and loggedIn from useAuth composable

Database

Set up a PostgreSQL database in your app using Drizzle ORM to manage data like users and sessions.

Payments

Set up Stripe, Polar, or Dodo Payments via Better Auth plugins to handle one-time and subscription payments.
