@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:

ch := make(chan int)

const ch = new Chan<number>();

ch := make(chan int, 5)

const ch = new Chan<number>(5);

for v := range ch {
    fmt.Println(v)
}

for await (const v of ch) {
    console.log(v);
}

ch <- 42

await ch.send(42);

v, ok := <-ch

const [v, ok] = await ch.recv();

close(ch)

ch.close();

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
