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. See src/node.js
for more information.
