safefs

Safe FS

Stop getting EMFILE errors! Open only as many files as the operating system supports.

Install

Node, Browserify

• Use: require('safefs')
• Install: npm install --save safefs

Ender

• Use: require('safefs')
• Install: ender add safefs

Usage

var safefs = require('safefs');

The following file system methods are available (but wrapped in safe way to prevent EMFILE errors):

• readFile(path, options?, next)
• writeFile(path, data, options?, next) - will also attempt to ensure the path exists
• appendFile(path, data, options?, next) - will also attempt to ensure the path exists
• mkdir(path, mode?, next) - mode defaults to 0o777 & (~process.umask())
• stat(path, next)
• readdir(path, next)
• unlink(path, next)
• rmdir(path, next)
• exists(path, next)

For other file system interaction, you can do the following:

// get a slot in the file system queue
require('safefs').openFile(function(closeFile){
	// do our file system interaction
	require('fs').someOtherMethod(a,b,c,function(err,a,b,c){
		// close the slot we are using in the file system queue
		closeFile();
	});
});

To make this possible we define a global variable called safefsGlobal that manages the available slots for interacting with the file system.
