@supabase/supabase-js

The official isomorphic JavaScript client for interacting with Supabase services like Postgres, Auth, and Realtime.

@supabase/supabase-js is the primary interface for connecting web and server-side applications to a Supabase backend. It provides a unified, TypeScript-first SDK to execute CRUD operations on Postgres via PostgREST, manage user sessions with GoTrue, and listen to database changes through Realtime. With over 3.3 million weekly downloads, the library simplifies complex tasks: use the createClient function to initialize a connection, then chain methods like .from('table').select() to query data or .auth.signInWithPassword() to handle security. It is built to run anywhere JavaScript does (including browsers, Node.js, and Edge Functions) and includes built-in support for generated types to ensure end-to-end type safety.
