Globals

Global Objects
These object are available in the global scope and can be accessed from anywhere.

global
The global namespace object.

In browsers, the top-level scope is the global scope. That means that in browsers if you're in the global scope var something will define a global variable. In Node this is different. The top-level scope is not the global scope; var something inside a Node module will be local to that module.

process
The process object. See the process object section.

require
To require modules. See the Modules section.

require.resolve
Use the internal require machinery to look up the location of a module, but rather than loading the module, just return the resolved filename.

require.paths
An array of search paths for require. This array can be modified to add custom paths.

Example: add a new path to the beginning of the search list require.paths.unshift('/usr/local/node');

__filename
The filename of the script being executed. This is the absolute path, and not necessarily the same filename passed in as a command line argument.

Example: running node example.js from /Users/mjr console.log(__filename); // /Users/mjr/example.js

__dirname
The dirname of the script being executed.

Example: running node example.js from /Users/mjr console.log(__dirname); // /Users/mjr

module
A reference to the current module. In particular module.exports is the same as the exports object. Seesrc/node.js for more information.

clearInterval(t)
The timer functions are global variables. See the timers section.
