`Error: EMFILE, open` when browserifying with coffee-reactify

[Taurus Colvin]

Hey there,

I'm getting what appears to be a file handle error on the react package.json file when attempting to browserify using coffee-reactify to transform cjsx.

Here's what I'm doing in a fresh directory named coffee-reactify-test:

In package.json

{
  "name": "foo",
  "version": "1.0.0",
  "description": "Foo project.",
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "browserify": "^9.0.3",
    "coffee-reactify": "^3.0.0",
    "coffee-script": "^1.9.1",
    "react": "^0.13.1"
  },
  "dependencies": {}
}

Run npm install to install node_modules (Command line)

npm install

Create an app.coffee file which requires my cjsx widget

Widget = require './widget.cjsx'

Create a widget.cjsx file which defines my widget

# @cjsx React.DOM

React = require('react')

Widget = React.createClass
  render: ->
    <div>
      My Widget
    </div>

module.exports = Widget

Run browserify with coffee-reactify transformation (Command line)

browserify -t coffee-reactify --extension=".cjsx" --extension=".coffee" app.coffee > bundle.js

Error

Error: EMFILE, open '/Users/foobar/coffee-reactify-test/node_modules/react/package.json'

Any insight appreciated...

Update: Issue is probably farther up the chain in browserify itself. Seems OSX file limits make it sad. Although my example is super simple and involves only two requires, I assume browserify is opening tons of dependent files under the hood -- thereby pushing the limit.

In any case, running:

ulimit -n 2560

Resolved the issue for me on OSX 10.9.5
