Ts-Chan – Go-Like Concurrency Primitives for TypeScript/JavaScript
Hey HN, I’m sharing ts-chan, an NPM package providing Go-like concurrency primitives, including channels and select statements, for TypeScript and JavaScript, supporting Node.js, Deno, Bun, and browsers. This is something I've built to make implementing Go-style "control loops" feasible in JavaScript, but there are many possible applications. Highlights: - Features a FIFO processing Chan class and versatile Select class for concurrency control. - Supports buffered channel and channel close semantics very close to Go's. - TypeScript-first implementation. - Defines a simple "channel protocol"…
In plain words
Ts-Chan is an NPM package that brings Go-style concurrency primitives to TypeScript and JavaScript, including channels and select statements. It provides a FIFO Chan class and Select class for managing concurrent operations, with support for buffered channels and close semantics similar to Go's implementation. The TypeScript-first tool works across Node.js, Deno, Bun, and browsers, enabling developers to build Go-style control loops in JavaScript environments.

Hey HN, I’m sharing ts-chan, an NPM package providing Go-like concurrency primitives, including channels and select statements, for TypeScript and JavaScript, supporting Node.js, Deno, Bun, and browsers.

Highlights: - Features a FIFO processing Chan class and versatile Select class for concurrency control. - Supports buffered channel and channel close semantics very close to Go's. - TypeScript-first implementation. - Defines a simple "channel protocol" inspired by JavaScript's iteration protocols, that's used by `Select`, and implemented by `Chan`. - Makes an effort to mitigate cycles caused by the behavior of JavaScript's microtask queue. - Ongoing project with active iteration for a production-ready module (pre-v1, so the API isn't guaranteed to be stable, but the implementation itself is).
