SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Convex schema design often requires structuring data with flat documents, correct validators, and enforceable indexes to ensure data integrity and scalable queries.

Core Features & Use Cases

  • Document-relational design principles that avoid deep nesting and rely on IDs for relationships.
  • Built-in patterns for one-to-many and many-to-many relationships with clear indexing strategies.
  • Validator references and type-safety guidance to prevent invalid data and runtime errors.
  • Use Case: Define a users table and related posts/comments with proper indexes for common queries.

Quick Start

Define your first convex schema.ts using the provided template and place it under convex/ to initialize your schema.

FAQPage Schema
How do I design a Convex schema with proper indexes and relationships?

To design a Convex schema, you define well-structured tables with flat documents and use IDs for relationships. This enforces data integrity through strict validators, proper indexing, and type-safe patterns for scalable queries.

What is the best way to model one-to-many relationships in Convex?

Modeling one-to-many relationships in Convex uses document-relational design principles that avoid deep nesting. You rely on IDs to link related tables and apply clear indexing strategies to ensure efficient, scalable queries across your data.

How do I add type-safe validators to a Convex database schema?

Add type-safe validators to a Convex database schema by applying strict validation patterns to your table definitions. This prevents invalid data insertion and runtime errors by enforcing specific types like enums, timestamps, and IDs.

Can I convert nested data into relational structures across Convex projects?

Yes, you can convert nested data into relational structures across Convex projects. The process involves refactoring deep document nesting into flat tables connected by IDs, applying strict validators and proper indexing to maintain data integrity.

When do I need to use indexes in a Convex schema?

You need to use indexes in a Convex schema when defining common queries that require scalable data retrieval. Proper indexing strategies enforce data integrity and ensure efficient lookups for one-to-many and many-to-many relationships.
