Description

I am downloading a file from google drive, which works perfectly with node fs module with this code

const drive = google.drive({ version: "v3", auth }); const dest = fs.createWriteStream("./downloaded.zip");

drive.files.get(
    { fileId: "google-file-id", alt: "media" },
    { responseType: "stream" },
    (err, res) => {
        res?.data.pipe(dest);
    }
);

but when using memfs I am receiving this error

"Error: ENOENT: no such file or directory, open '/home/yory/casino-odr-v2/services/casino-odr-v2/downloaded.zip'\n at createError (/home/yory/casino-odr-v2/node_modules/.pnpm/memfs@3.4.13/node_modules/memfs/lib/volume.js:128:17)\n at Volume.openFile (/home/yory/casino-odr-v2/node_modules/.pnpm/memfs@3.4.13/node_modules/memfs/lib/volume.js:850:23)\n at Volume.openBase (/home/yory/casino-odr-v2/node_modules/.pnpm/memfs@3.4.13/node_modules/memfs/lib/volume.js:861:25)\n at Immediate.

Contributor guide

Research direction
Investigate why createWriteStream fails with ENOENT; check if memfs requires parent directory to exist before opening a write stream and whether it automatically creates directories like fs does. Test using mkdirp before write stream or explore the volume implementation.
