@harnyk/chan - Go channels for TypeScript

This package is my humble attempt to provide a Chan<T> class for TypeScript, which would be as much as possible similar to Go's chan T type.

Installation

npm install @harnyk/chan

Usage

See the tests and examples for more information.

Brief reference:

	Go equivalent	TypeScript
Create a channel of `number` with no buffer:	ch := make(chan int)	const ch = new Chan<number>();
Create a channel of `number` with fixed-size buffer:	ch := make(chan int, 5)	const ch = new Chan<number>(5);
Iterate over `Chan` with `for await`	for v := range ch { fmt.Println(v) }	for await (const v of ch) { console.log(v); }
Send a value to `Chan` with `send`	ch <- 42	await ch.send(42);
Receive a value from `Chan` with `recv`	v, ok := <-ch	const [v, ok] = await ch.recv();
Close `Chan`	close(ch)	ch.close();
Select over multiple channels	select { case ch <- 42: fmt.Println("sent") case v := <-ch1: fmt.Printf("Received %d\n", v) default: fmt.Println("default") }	await select() .send(ch, 42, () => console.log('sent')) .recv(ch1, (v) => console.log(`Received ${v}`)) .default(() => console.log('default'));

What is supported

• asynchronous iterating over Chan<T> with for await
• asynchronous send and recv
• select-ing over multiple channels
