Crate type_bridge_server 

type-bridge-server

Transport-agnostic query pipeline for TypeDB with composable interceptors.

This crate provides both a library and a standalone binary for executing TypeQL queries through a structured pipeline: validate → intercept → compile → execute → intercept.

Feature flags

Feature	Default	Description
typedb	yes	TypeDB backend via TypeDBClient
axum-transport	yes	HTTP server with /query, /query/validate, /health, /schema endpoints

Disable defaults with --no-default-features to use the core pipeline as a library without any transport or backend.

Library usage

use type_bridge_server::pipeline::PipelineBuilder;
use type_bridge_server::schema_source::InMemorySchemaSource;

let pipeline = PipelineBuilder::new(my_executor)
    .with_schema_source(InMemorySchemaSource::new(tql_schema))
    .with_default_database("my_db")
    .with_interceptor(my_audit_log)
    .build()?;

let output = pipeline.execute_query(input).await?;

Extension points

• QueryExecutor — implement to use a non-TypeDB backend or a mock.
• Interceptor — implement to add cross-cutting concerns (audit, auth, rate limiting).
• SchemaSource — implement to load TypeQL schemas from custom sources.
