javascript - Error: EMFILE: too many open files -


using nw.js, trying save images in array of img elements different random names.

but having few errors, wrong code?

for (i = 0; < imgs.length; i++) {  request(imgs[i].getattribute('src')).on('error', function(err) {   throw err  }).pipe(fs.createwritestream('data/imgs/' + randomstring)) }

imgs[] array of 100-500 html img element, receiving 

error: emfile: many open files, open *<directory>*

and error:

"uncaught error: socket hang up"

although saves images, of them corrupted, , creates many images there is.

use graceful-fs module, drop-in replacement fs module. wrapper around native fs module. quoting docs of graceful-fs module,

queues open , readdir calls, , retries them once closes if there emfile error many file descriptors.

since exposes same apis native fs module, can use normal fs module.

// use fs var fs = require('graceful-fs');

note: library created by, isaac z. schlueter, 1 of core developers of node.js.
