import { iterateReader } from "https://deno.land/std@0.223.0/streams/iterate_reader.ts";

Turns a Reader, r, into an async iterator.

Examples

Example 1

import { iterateReader } from "https://deno.land/std@0.223.0/streams/iterate_reader.ts";

using f = await Deno.open("/etc/passwd");
for await (const chunk of iterateReader(f)) {
  console.log(chunk);
}

Second argument can be used to tune size of a buffer. Default size of the buffer is 32kB.

Example 2

import { iterateReader } from "https://deno.land/std@0.223.0/streams/iterate_reader.ts";

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

Parameters

optional
options: { bufSize?: number; }

Returns

AsyncIterableIterator<Uint8Array>
