The Native Bridge

Koda Zenith is unique because it doesn’t try to rewrite everything in JavaScript. Instead, it creates high-performance “bridges” to specialized languages that excel in specific domains. This is the heart of our “Post-Web” philosophy.

Why the Polyglot Stack?

We believe in using the best tool for the job. Our native core is a symphony of three industrial powerhouses:

  • Zig: We use Zig for extreme memory control, zero-copy operations, and building the runtime’s core I/O. Its lack of hidden control flow makes it perfect for our performance-critical base.
  • Rust: Used for safety-critical components, Web3 smart contracts, and heavy AI computation. Rust’s ownership model ensures that our high-level abstractions are memory-safe.
  • Elixir Semantics: While we run on modern JS engines, we adopt the Elixir/Erlang Actor Model for resilience. This gives us the ability to handle millions of connections without breaking.

How it Works: Native Direct Invoke (NDI)

Koda Zenith uses Tagged Templates and our proprietary NDI protocol to call these languages with near-zero overhead. There is no external process spawning; the code is compiled directly into the Zenith runtime.

import { zig, rust } from '@koda/native';

// Offload heavy transformation to a Zig binary
// This happens in the same memory space as your JS logic
const optimizedData = await zig.call('fast_compute_transform', rawBuffer);

// Verify safety-critical logic in Rust
const isValid = await rust.verify('security_check', optimizedData);

Zero-Copy Data Sharing

The most significant bottleneck in polyglot systems is data serialization (JSON, Protobuf). Koda Zenith eliminates this by using Shared Memory Vistas. Both the JS engine and the native binaries operate on the same physical RAM buffer, meaning passing a 1GB dataset between them takes 0ms.

The Roadmap to Industrial Native

We are currently stabilizing the NDI protocol and expanding our standard library to include more native high-performance components. Our goal is a future where “Native” is as easy to use as “NPM”.
