fifo

Simple first-in-first-out queue for Deno.

import FIFO from "https://deno.land/x/fifo/mod.ts";

const queue = new FIFO<number>();

queue.push(1);
queue.push(2);
queue.push(3);

console.log(queue.length); // 3

console.log(queue.shift()); // 1
console.log(queue.shift()); // 2
console.log(queue.shift()); // 3

console.log(queue.shift()); // undefined

Supports both sync and async iteration.

// Consumes queue
for (const item of queue) {
  console.log(item);
}

// Consumes queue, waits for new items
for await (const item of queue) {
  console.log(item);
}
