supabase-js

Why we included this project

Supabase's official JavaScript client is what you use to talk to your Postgres data from TypeScript or plain JavaScript. One package bundles the whole SDK surface, so the same code handles database reads and writes, realtime subscriptions, file storage, authentication, and edge function calls. For vector work it is also the practical route into pgvector: you store embeddings in a Postgres table and invoke a similarity-search function through the client's rpc() method, which is how most Supabase semantic-search and RAG setups are wired together. Since it runs in both Node and the browser, a full-stack app can share one query layer across server and client. It is a client library rather than a database, so expect to pair it with a running Supabase project or a self-hosted instance.
