hmm doesn't seem like Response
is provided as a global in Node.js... would likely need to allow the current interface as well with Uint8Array
.
Actually this works in Node v18:
import { open } from 'node:fs/promises';
let file = await open('./package.json');
let response = new Response(file.readableWebStream());
await response.json();
file.read() // promise! oh no, file still open :x
EDIT: Errr actually, a tiny detail in the node docs:
While the
ReadableStream
will read the file to completion, it will not close theFileHandle
automatically. User code must still call thefileHandle.close()
method.
Since we don't want to manage open file handles, it seems like the correct way to do this is to first create a Readable
which auto-closes the file (when read) and get a ReadableStream
from that. This way the caller is in control over then the file is closed (and doesn't need a reference to the original FileHandle
).
import { open } from 'node:fs/promises';
import { Readable } from 'node:stream';
let file = await open('./package.json');
let readable = file.createReadStream({ autoClose: true });
let response = new Response(Readable.toWeb(readable));
await response.json()
file.read() // Error! file closed
