TypeBridge connects typed Python, TypeScript, and Rust applications to TypeDB through one semantic engine.

Build typed TypeDB applications¶

TypeBridge is a multi-language application toolkit for TypeDB. Define a schema once, project typed models for Python, TypeScript/Node, and Rust, then use the same Rust-owned query, migration, validation, and ORM semantics locally or through the TypeBridge server.

Python

Generated value/model classes, concise managers, transactions, and immutable direct or remote queries.

Python quick start
TypeScript / Node

Generated branded values, typed managers, native execution, and direct or remote queries.

Node SDK
Rust

Generated schema crates, async CRUD, transactions, and immutable queries bound to a canonical schema.

Rust client
Schema and server

Versioned Split-YAML workspaces, migrations, multi-target generation, and a hardened remote query server.

Schema workflows

Python and Node generated packages are typed language projections, not schema authorities or independent implementations. Generated Rust applications and the standalone server consume the same canonical contracts. This keeps cardinality, roles, inheritance, value coercion, query validation, and migration behavior aligned.
