Deno.stdin raw map?

const stdin = Deno.stdin;
stdin.setRaw(true, {cbreak: Deno.build.os !== "windows"});

const maxBuffer = new Uint8Array(1024);
const read = async () => {
    const size = await stdin.read(maxBuffer);
    const buffer = maxBuffer.subarray(0, size || 0).toString();

    Deno.writeTextFileSync("buffer.txt", buffer + "\n", {append: true});

    setTimeout(read, 1000 / 60);
};

read();
