This module provides the essential three pillars for building robust full-stack applications on Supabase. It implements comprehensive user authentication (including OAuth, email/password, and session management), secure file storage (uploading, downloading, and managing signed URLs), and real-time data subscriptions (listening to Postgres changes, presence, and broadcasts). It is crucial for developing modern, live-updating, and highly secure web services.

This tool collects a comprehensive, redacted diagnostic bundle from a Supabase project. It systematically tests connectivity, authentication (Auth), Realtime capabilities, Storage buckets, and Row-Level Security (RLS) policies. The resulting archive is designed for sharing with support teams to accelerate troubleshooting of complex issues like connection failures or misconfigurations.

A comprehensive guide for managing resource limits and quotas across all Supabase services (API, Auth, Storage, Realtime, Edge Functions). Learn how to understand tier-specific limits, configure connection pooling using Supavisor (Transaction/Session mode), and implement robust retry logic with exponential backoff to gracefully handle 429 rate limiting errors, ensuring high application reliability.

A comprehensive guide for migrating and upgrading the Supabase SDK (JS/TS and Python) and CLI. This tool detects breaking changes, covers major version jumps (e.g., v1 to v2), and provides automated code migration patterns for Auth, Realtime, and Storage APIs. Use this when updating your project to a new Supabase version or when encountering API deprecations.

A comprehensive guide to building event-driven architectures using Supabase. It covers four core event mechanisms: Database Webhooks (pg_net), Postgres LISTEN/NOTIFY, Edge Function HTTP calls, and Realtime subscriptions. Includes production-ready SQL triggers, signature verification logic, and best practices for handling data changes (INSERT, UPDATE, DELETE) as external HTTP events.

Explains building secure real-time communication with WebSocket servers, Socket.io rooms, SSE, Redis scaling, and resilient clients for multi-server Node.js apps.

VideoDB ingests files, URLs, RTSP feeds, or desktop captures to build searchable visual and spoken indexes, edit timelines with overlays/subtitles, generate media, and emit realtime alerts for monitoring workflows.

This comprehensive guide details how to correctly implement and manage Firebase Realtime Database within Flutter applications. It covers critical best practices including data modeling (using flattened JSON trees), utilizing real-time listeners, ensuring offline persistence, performing atomic transactions, and implementing security rules. Ideal for applications requiring extremely low-latency synchronization and constant state monitoring.

A comprehensive guide for developers working with Supabase. Covers best practices for database interaction, robust authorization using Row Level Security (RLS), secure authentication (Auth), and integrating various Supabase products (Storage, Realtime, Edge Functions). Essential for preventing common security vulnerabilities like BOLA/IDOR and ensuring data integrity across your application stack.
