SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Convex schema design is error-prone and time-consuming. This Skill guides you to build robust, well-validated schemas with clear relationships and efficient indexes, reducing churn when creating or updating schemas.

Core Features & Use Cases

  • Enforces flat, ID-based relationships and recommended indexing.
  • Provides patterns for common data models (one-to-many, many-to-many, hierarchical) and how to model them in Convex schemas.
  • Helps migrate nested structures to relational schemas and ensures strict validators for type safety.

Quick Start

Provide your data model and run the schema-builder to generate a validated Convex schema.ts skeleton.

FAQPage Schema
How do I design a Convex schema with flat ID-based relationships?

To design a Convex schema with flat ID-based relationships, you define tables using strict, type-safe validators and reference related documents by their system IDs rather than nesting objects. This approach enforces relational patterns and reduces data migration churn.

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

Modeling one-to-many and many-to-many relationships in Convex involves storing document IDs in arrays or single fields and applying recommended indexing strategies. This ensures efficient queries and maintains strict type safety across your schema.

How do I add indexes to a Convex schema for efficient querying?

You add indexes to a Convex schema by defining index definitions within your schema.ts file for fields frequently queried or used in relationship lookups. Applying the correct index strategy optimizes data retrieval and enforces validation rules.

Can I migrate nested data structures to a relational Convex schema?

You can migrate nested data structures to a relational Convex schema by breaking down embedded objects into separate tables and linking them using flat ID-based relationships. This process ensures strict validators and efficient index strategies are applied.

Does my Convex schema need strict type-safe validators for every table?

Your Convex schema needs strict type-safe validators for every table to enforce data integrity and prevent runtime errors. Defining explicit types for all fields ensures that your application handles data predictably during creation and updates.

When should I update my convex/schema.ts file?

You should update your convex/schema.ts file when creating new data models, adding tables, modifying relationships, or changing index strategies. Keeping your schema validated during these updates prevents structural errors and maintains type safety.
