convex-typegen

A blazing fast Rust type generator for ConvexDB schemas and functions.

Features

• 🚀 Blazing Fast: Efficient AST parsing and type generation using oxc
• 🔄 Auto-regeneration: Types automatically update when schema or function files change
• 🛠️ Complete Type System:
  • Full schema type generation (tables, columns, unions)
  • Function argument types for queries, mutations, and actions
  • Support for all Convex types (arrays, objects, records, literals)
  • Proper handling of optional fields and complex types
• 🔒 Type Safety:
  • Compile-time type checking
  • Automatic serialization/deserialization
  • Zero runtime overhead
• 🎨 Developer Experience:
  • Clean, idiomatic Rust code generation
  • Smart function path resolution (e.g., "auth:login")
  • Detailed documentation for generated types

Quick Start

1. Add dependencies using cargo:

cargo add convex-typegen serde serde_json
cargo add --build convex-typegen

2. Add the following to your build.rs file:

use convex_typegen::generate;

fn main() {
    generate().unwrap();
}

3. Run cargo build to generate the types.

You can watch a demo video here to learn more.

Supported Types

• Basic Types: string, number, boolean, null, int64, bytes
• Complex Types: array, object, record, union, optional
• Special Types: any, literal, id
• Custom Types: Automatic enum generation for union types
