Error: EMFILE, too many open files with Gulp.watch

Question

My gulpfile.js looks like this:

gulp.task('default', ['build', 'browser-sync'], function () {
    gulp.watch("**/*.css", ['bs-reload']);
    gulp.watch(["**/*.js", "!**/*/node_modules/**/*.*"], ['bs-reload']);
    gulp.watch("**/*.html", ['bs-reload']);
});

Even though I have excluded node_modules it is trying to add a watch to all node_modules.

How can exclude it?

Please note that the node_modules does not exist at root of the project, infect it is at above the root of the project, so why it is even bother including the same?

Answer 1

Try this as a more resilient drop in replacement for fs:

graceful-fs

Globally patch fs like this:

var realFs = require('fs')
var gracefulFs = require('graceful-fs')
gracefulFs.gracefulify(realFs)
