Write Once, Ship to Both Ecosystems

BridgeRust wraps PyO3 and napi-rs behind one macro-first workflow.
You keep Rust-level performance and safety while shipping native packages to both Python and Node.js.

Rust Core

use bridgerust::prelude::*;

#[bridge]
struct Calculator {
    value: f64,
}

#[bridge_methods]
impl Calculator {
    #[constructor]
    fn new() -> Self {
        Self { value: 0.0 }
    }

    #[method]
    fn add(&mut self, value: f64) {
        self.value += value;
    }

    #[method]
    fn get_value(&self) -> f64 {
        self.value
    }
}

Python Usage

from calculator import Calculator

calc = Calculator()
calc.add(10.5)
calc.add(5.3)

print(calc.get_value())  # 15.8

Node.js Usage

import { Calculator } from "calculator";

const calc = new Calculator();
calc.add(10.5);
calc.add(5.3);

console.log(calc.getValue()); // 15.8

One implementation. Two native SDKs. No duplicated glue code.

Where Teams Use BridgeRust

Universal SDKs Build one Rust client and publish to both PyPI and npm.

Data Pipelines Move transformation-heavy paths to Rust while preserving Python/Node ergonomics.

Infra Utilities Ship fast parsers, formatters, and protocol tools into multiple runtimes.

Realtime Services Use Rust for throughput and expose a developer-friendly API surface.

BridgeRust vs Building Separately

Capability	BridgeRust	Separate Python + Node Implementations
Core logic duplication	None	High
Native performance	Yes	Depends
Cross-language type consistency	Strong	Manual
Release workflow	Unified	Split
Long-term maintenance	Lower	Higher
