supabase-js ist eine umfassende Client-Bibliothek, die entwickelt wurde, um Frontend-Anwendungen mit einem gehosteten Backend-as-a-Service zu integrieren. Sie bietet ein einheitliches Interface für die Interaktion mit einer PostgreSQL-Datenbank, Identitätsmanagementsystemen, Cloud-Objektspeicherung und Echtzeit-Datensynchronisierung. Die Bibliothek bietet ein isomorphes Client-Design, das sowohl in Browser- als auch in Serverumgebungen funktioniert. Sie zeichnet sich durch einen Typ-sicheren Ansatz aus, nutzt TypeScript, um Datenbankschemata direkt auf Client-seitige Definitionen zu mappen, und verwendet eine PostgREST-basierte API, um JavaScript-Aufrufe in RESTful-Requests zu übersetzen. Der Client deckt ein breites Spektrum an Funktionen ab, einschließlich Nutzerauthentifizierung via OAuth, OIDC und Passkeys sowie Sitzungsmanagement unter Verwendung signierter Token. Er verwaltet große Binärdaten über ein S3-kompatibles Speicher-Interface und ermöglicht Live-Anwendungsupdates via WebSocket-basierter Abonnements für Datenbankänderungen und Präsenzsynchronisierung. Zusätzliche Funktionalität umfasst den Aufruf von Serverless-Edge-Functions und die Durchführung von Ähnlichkeitssuchen unter Verwendung von Vektor-Embeddings.

Dieses Projekt ist ein Zwei-Faktor-Authentifizierungs-Manager, der Zeit- und Zähler-basierte Einmalpasswörter generiert, um Online-Konten zu sichern.
