--- id: introduction title: Introduction --- This reference documents every object and method available in Supabase's isomorphic JavaScript library, `supabase-js`. You can use `supabase-js` to interact with your Postgres database, listen to database changes, invoke Deno Edge Functions, build login and user management functionality, and manage large files. To convert SQL queries to `supabase-js` calls, use the [SQL to REST API translator](/docs/guides/api/sql-to-rest).
