appwrite-backend

What problem does it solve?

This Skill solves the complexity of building production-grade Appwrite backend applications by providing authoritative patterns, critical rules, and best practices for TablesDB, Authentication, Storage, Functions, Realtime, and Messaging. It prevents common failures such as race conditions from read-modify-write patterns, N+1 query performance bottlenecks, deprecated API usage, and incorrect SDK version pinning.

Core Features & Use Cases

• TablesDB Mastery: Atomic operators for race-free updates, cursor pagination for performance, Query.select() for relationship expansion, and bulk operations for mass data processing.
• Authentication & Security: OAuth 2.0, MFA/TOTP, SSR session management, JWT for Functions, and granular permission patterns using Permission and Role helpers.
• Serverless Functions: Cold start optimization, event triggers over polling, domain-based function grouping, and async execution patterns for long-running workflows.
• Use Case: A developer building a cross-platform Flutter and Node.js app can use this Skill to correctly implement self-hosted Appwrite 1.9.x with pinned SDK versions, set up Realtime subscriptions with server-side filtering, and configure cost-optimized image transformations.

Quick Start

Use the appwrite-backend skill to implement a race-free inventory decrement with atomic operators and a transaction for order creation in your Appwrite TablesDB store.
