sk-auth

• Authentication library designed for SvelteKit with built-in OAuth providers and extensive customization options.
• Supports Typescript natively with first-class type definitions.
• Enables easy integration of authentication flows (OAuth, SAML SSO, credential logins) through a provider-based system.

Key Features

• OAuth2 Support: Comes with a pre-built OAuth2Provider class for standardized OAuth2 flows, handling authorization redirects, token retrieval, and profile fetching.
• Session Management: Augments SvelteKit's session handling to include user data via getSession.
• Callbacks: Provides customizable hooks (signIn, jwt, session, redirect) for fine-grained control over authentication behavior.
• Unopinionated Design: Allows custom provider implementations by extending the base Provider class.

Target Audience

• Developers building SvelteKit applications requiring authentication.
• Projects needing OAuth2 or custom auth providers without restrictive defaults.

Example Use Case

const appAuth = new SvelteKitAuth({  
  providers: [new GoogleOAuthProvider({ /* config */ })],  
  jwtSecret: "your-secret-key",  
});  

For advanced use, developers can create custom providers or extend existing ones.
