## 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.
