Example 1

import { iterateReader } from "https://deno.land/std@0.221.0/io/iterate_reader.ts";

using file = await Deno.open("/etc/passwd");
for await (const chunk of iterateReader(file)) {

import { iterateReader } from "https://deno.land/std@0.221.0/io/iterate_reader.ts";

using file = await Deno.open("/etc/passwd");
const iter = iterateReader(file, {
  bufSize: 1024 * 1024
});
for await (const chunk of iter) {
  console.log(chunk);
}

Parameters

reader: Reader
optional
options: { bufSize?: number; }
