TypeBridge is a typed application toolkit for TypeDB. A versioned Split-YAML workspace is the schema authority. TypeBridge validates that workspace and generates Python, TypeScript/Node, and Rust bindings that share one Rust-owned schema, query, migration, validation, and ORM engine.
One system, three generated SDKs
| Surface | Generated application API | Distribution |
|---|---|---|
| Python | Value classes, model managers, transactions, direct/remote queries | type-bridge |
| TypeScript / Node | Branded values, model managers, native and remote queries | @type-bridge/node |
| Rust | Schema-bound create/model types, async CRUD and immutable queries | type-bridge |
| CLI | Split-YAML checks, migrations, and all three projections | Included with the Python package |
| Server | Remote V2 query execution over the same generated contract | ghcr.io/ds1sqe/type-bridge-server |
TypeBridge preserves TypeDB concepts directly: independent attributes, entities, relations, roles, inheritance, cardinality, ordering, keys, and uniqueness remain typed from schema through hydrated results.
Start from Split-YAML
Install the CLI and Python runtime:
pip install type-bridge
Create typebridge.yaml, a schema-set manifest, and one or more schema
fragments. Configure the generated package output in the workspace, then run:
type-bridge --manifest typebridge.yaml schema check
type-bridge --manifest typebridge.yaml schema generate
type-bridge --manifest typebridge.yaml migration make --name initial
type-bridge --manifest typebridge.yaml migration apply --environment development
One generation snapshot writes every configured Python, TypeScript, and Rust
package. Generated packages privately embed the verified authority used by
their managers and direct or remote queries, so ordinary applications never
configure or read an external authority JSON. A workspace deploying the optional
generic server can additionally configure artifacts.schema-authority.output;
the server mounts that generated, source-free artifact instead of compiling
YAML or accepting a user-maintained JSON schema.
The generated Python package owns the concise single-type manager:
from app_models import Age, Person, PersonId
from type_bridge import Database
db = Database(address="localhost:1729", database="example")
db.connect()
ada = Person(person_id=PersonId("ada"), age=Age(36))
Person.manager(db).put(ada)
people = Person.manager(db).filter(age__gte=18).all()
Use its package-local query session when a query spans types:
session = Person.query(db)
person = session.exact(Person)
adults = (
session.query(person)
.where(person.field(Person.age).gte(Age(18)))
.rows(limit=100)
)
Continue with the Python quick start, Split-YAML reference, and data guide.
TypeScript / Node
npm install @type-bridge/node
Import application values from the generated package and connection primitives
from @type-bridge/node:
import { RustDatabase } from "@type-bridge/node";
import { Age, Person, PersonId } from "./generated/models/index.js";
const db = RustDatabase.connect("localhost:1729", "example", {
username: "admin",
password: "password",
});
const ada = Person.create({
personId: PersonId.create("ada"),
age: Age.create(36n),
});
Person.manager(db).put(ada);
const people = Person.manager(db).filter({ age__gte: Age.create(18n) }).all();
See the TypeScript/Node guide for generated managers, transactions, and direct/remote queries.
Rust
The same workspace emits a schema-bound Rust crate. The generated SDK uses
Rust 1.88+ and the crates.io type-bridge runtime:
[dependencies]
type-bridge = "2"
Follow the Rust client guide for generation, direct execution, transactions, and remote queries.
