SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Convex backends often require boilerplate for common patterns like loading related data, authenticated access, and data validation. This guide introduces the official convex-helpers utilities to streamline these tasks and promote best practices.

Core Features & Use Cases

  • Relationship Helpers: Traverse relationships between tables in a readable, type-safe way and load related data.
  • Custom Functions (Data Protection) ⭐ MOST IMPORTANT: Wrap queries/mutations to automatically enforce auth, multi-tenant access, and context injection.
  • Filter Helper: Apply complex TypeScript filters to queries.
  • Sessions: Track anonymous users and behavior across requests.
  • Zod Validation: Use Zod schemas for validation instead of built-in validators.
  • Migrations, Triggers, Aggregations: Tools to migrate data, react to changes, and compute aggregates.
  • Common Patterns: Authed queries, loading related data, batch operations with error handling.
  • Best Practices: Guidance to start with convex-helpers, use custom functions for auth, etc.

Quick Start

Install convex-helpers and start using its relationship, custom function, and session utilities in your Convex backend.

Frequently Asked Questions about convex-helpers-guide

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I enforce authentication and access control in Convex backends?▼

Use custom function wrappers from convex-helpers to enforce auth and multi-tenant access control in Convex. They automatically inject context and protect queries and mutations, eliminating manual authentication boilerplate.

What is the best way to validate data in Convex mutations?▼

Data validation in Convex is best handled using Zod schemas with convex-helpers. This replaces built-in validators, providing strict type safety and readable schema definitions for your backend mutations.

How do I load related data across tables in Convex?▼

Relationship helpers in convex-helpers let you load related data across Convex tables. They provide a readable, type-safe way to traverse relationships without writing complex manual query logic.

Can I use Zod schemas instead of built-in validators for Convex queries?▼

Yes, convex-helpers integrates Zod schemas to validate Convex queries and mutations. This approach replaces built-in validators, ensuring robust data validation and enhanced TypeScript type safety.

How do I run data migrations and triggers in a Convex backend?▼

Convex-helpers provides dedicated tools to run data migrations and set up triggers in your Convex backend. These utilities help you react to data changes and compute aggregates efficiently.

Does convex-helpers support tracking anonymous user sessions?▼

Yes, convex-helpers includes session utilities to track anonymous users and their behavior across requests. This allows you to monitor activity before a user formally authenticates.
