Sveltekit Example

Overview:

This product analysis examines an example application that demonstrates the use of Firebase authentication on the client-side, implemented using SvelteKit and accessed via a Svelte Store. The application has been updated to use the Firebase 9.0 SDK for faster startup and a higher Lighthouse score. It also demonstrates the synchronization of the client-side authentication state with the server to set a cookie and provide a SvelteKit "session". The example utilizes lazy-loading of Firebase SDK packages from the CDN to ensure quick application startup. Additionally, the analysis outlines the potential additions to the example application's roadmap, including the utilization of the firebase-admin SDK for server-side operations, implementation of auth guards, customization of the UI based on user roles, integration of SvelteKit stores with Firestore, and the efficient use of Firestore in both server-side rendering (SSR) and single-page application (SPA) modes.

Features:

• Firebase Authentication: Demonstrates the integration of Firebase authentication on the client-side using SvelteKit and a Svelte Store.
• Lazy-Loading of Firebase SDK Packages: Utilizes lazy-loading of Firebase SDK packages from the CDN to optimize application startup time and ensure the initialization of only necessary packages based on user authentication status.
• Server-Client Authentication State Sync: Illustrates the synchronization of the client-side authentication state with the server by setting a cookie and providing a SvelteKit "session".
• Firebase-Admin SDK Integration: Future addition to show the usage of the firebase-admin SDK for server-side operations and enabling Firebase authentication checks within server endpoints and server-side rendering (SSR) pages with data from Firestore.
• Auth Guards: Planned feature addition for preventing routes from rendering or displaying an "access denied" message based on the user's authentication status.
• Role-Based UI Customization: Planned feature addition to customize the UI elements based on the user's authentication claims, allowing for the hiding or showing of certain elements for users with specific permissions.
• SvelteKit Stores with Firestore: Planned feature addition to simplify data querying and subscription using SvelteKit stores with Firestore.
• Efficient Firestore Integration: Planned feature addition to seamlessly handle data retrieval in both SSR and SPA modes, ensuring the transparent transition of SSR data to client-side subscriptions for live updates.

Summary:

This product analysis showcases an example application that demonstrates the integration of Firebase authentication with SvelteKit. It highlights the use of the Firebase 9.0 SDK, lazy-loading of SDK packages, and synchronization of authentication state between the client and server. The analysis also outlines the potential roadmap for additional features, including the utilization of the firebase-admin SDK, auth guards, role-based UI customization, integration of SvelteKit stores with Firestore, and efficient Firestore integration for SSR and SPA modes. Overall, this example serves as a useful resource for developers looking to implement Firebase authentication in a SvelteKit project.
