Provides node's process.env object functionality as stand-alone functions instead of a C++ fake object that does weird things. As an added bonus, if running node with Proxies enabled ("node --harmony") it also exports a function that creates an Environment object that is similar to process.env but behaves like a real object.


	npm install environment


Mostly self-explanatory:

  • environment.get(key)
  • environment.set(key, value)
  • environment.delete(key)
  • environment.enumerate()

Environment object

If Proxy is available, due to running node using the --harmony flag, a constructor is exported as well which allows the creation of Environment objects.

These objects aren't entirely normal JavaScript objects, but they're much closer than node's process.env. Environment.prototype doesn't inherit from Object.prototype but it does have most of the functions from it. toString, valueOf, isPrototypeOf, hasOwnProperty, as well as constructor pointing to Environment.

It's possible to add methods to Environment.prototype and have them work on instances correctly. It's possible to change an instance's __proto__ and point it to something else and also have that work correctly (though Object.getPrototypeOf may not reflect the change).

// normal creation 
var env = require('environment').create();
// or modifying the prototype 
var Environment = require('environment');
Environment.prototype.paths = function paths(){
    return this.PATH.split(process.platform === 'win32' ? ';' : ':');
var env = new Environment;
