To initialize CloudBase relational database in a browser app, use the canonical `@cloudbase/js-sdk` pattern by calling `cloudbase.init({ env })` to create a shared app instance, then instantiate a reusable `db` client via `app.rdb()`.

Yes, you can run Supabase-style queries from the frontend with CloudBase by using the `.from(table).select/insert/update/delete(...)` pattern on the initialized `db` client for standard read and write operations.

The best way to manage relational database schema for CloudBase web apps is to route DDL and admin work to the `relational-database-tool`, keeping browser code focused strictly on data access and avoiding MCP-based management mistakes.

Yes, the CloudBase browser SDK supports replacing a Supabase browser client by providing standardized initialization and enabling equivalent `.from(table).select(...)` query syntax for frontend data access without backend provisioning.

You should avoid schema management in the browser when using CloudBase RDB because frontend code must maintain a clear separation of responsibilities, focusing solely on data access while routing DDL and admin work to dedicated admin flows.
