GojHigh-performance concurrency runtime for JavaScript — built in Rust.

Native performance. Go-style ergonomics. JavaScript simplicity.

⚡️

Extremely fast

Built with Rust and napi-rs, Goj uses a custom lightweight scheduler to spawn and coordinate millions of goroutines with minimal overhead.

🚀

Goj implements real M:N concurrency: green threads mapped to native threads, with cooperative scheduling and zero-cost async.

📦

Communicate through channels with blocking or async semantics, and coordinate completion with waitgroups — just like in Go.

🦾

Ergonomic and type-safe API designed for idiomatic usage in modern TypeScript — no boilerplate, no complexity.

🔄

Uses zero-copy buffers between JS and Rust for passing data efficiently, avoiding serialization overhead.

📈

Optimized for handling millions of concurrent tasks, making it ideal for real-time apps, agents, simulations, and more.
