deno-cava

cava cli bindings to deno:

// deno-cava uses async iterators to stream the output of cava.
import { streamLines } from "https://deno.land/x/cava/mod.ts";

for await (const line of streamLines()) {
  // format each number in the array as a 6 digit number (leading zeros)
  const formatted = [...line].map((n) => n.toString().padStart(6, "0")).join(
    " ",
  );
  console.log(formatted);
}
