# Global Objects
|
|
|
|
<!--introduced_in=v0.10.0-->
|
|
<!-- type=misc -->
|
|
|
|
These objects are available in all modules. The following variables may appear
|
|
to be global but are not. They exist only in the scope of modules, see the
|
|
[module system documentation][]:
|
|
|
|
- [`__dirname`][]
|
|
- [`__filename`][]
|
|
- [`exports`][]
|
|
- [`module`][]
|
|
- [`require()`][]
|
|
|
|
The objects listed here are specific to Node.js. There are a number of
|
|
[built-in objects][] that are part of the JavaScript language itself, which are
|
|
also globally accessible.
|
|
|
|
## Class: Buffer
|
|
<!-- YAML
|
|
added: v0.1.103
|
|
-->
|
|
|
|
<!-- type=global -->
|
|
|
|
* {Function}
|
|
|
|
Used to handle binary data. See the [buffer section][].
|
|
|
|
## \_\_dirname
|
|
|
|
This variable may appear to be global but is not. See [`__dirname`].
|
|
|
|
## \_\_filename
|
|
|
|
This variable may appear to be global but is not. See [`__filename`].
|
|
|
|
## clearImmediate(immediateObject)
|
|
<!-- YAML
|
|
added: v0.9.1
|
|
-->
|
|
|
|
<!--type=global-->
|
|
|
|
[`clearImmediate`] is described in the [timers][] section.
|
|
|
|
## clearInterval(intervalObject)
|
|
<!-- YAML
|
|
added: v0.0.1
|
|
-->
|
|
|
|
<!--type=global-->
|
|
|
|
[`clearInterval`] is described in the [timers][] section.
|
|
|
|
## clearTimeout(timeoutObject)
|
|
<!-- YAML
|
|
added: v0.0.1
|
|
-->
|
|
|
|
<!--type=global-->
|
|
|
|
[`clearTimeout`] is described in the [timers][] section.
|
|
|
|
## console
|
|
<!-- YAML
|
|
added: v0.1.100
|
|
-->
|
|
|
|
<!-- type=global -->
|
|
|
|
* {Object}
|
|
|
|
Used to print to stdout and stderr. See the [`console`][] section.
|
|
|
|
## exports
|
|
|
|
This variable may appear to be global but is not. See [`exports`].
|
|
|
|
## global
|
|
<!-- YAML
|
|
added: v0.1.27
|
|
-->
|
|
|
|
<!-- type=global -->
|
|
|
|
* {Object} The global namespace object.
|
|
|
|
In browsers, the top-level scope is the global scope. This means that
|
|
within the browser `var something` will define a new global variable. In
|
|
Node.js this is different. The top-level scope is not the global scope;
|
|
`var something` inside a Node.js module will be local to that module.
|
|
|
|
## module
|
|
|
|
This variable may appear to be global but is not. See [`module`].
|
|
|
|
## process

|
<!-- YAML
|
|
added: v0.1.7
|
|
-->
|
|
|
|
<!-- type=global -->
|
|
|
|
* {Object}
|
|
|
|
The process object. See the [`process` object][] section.
|
|
|
|
## require()
|
|
|
|
This variable may appear to be global but is not. See [`require()`].
|
|
|
|

|
|
added: v0.9.1
|

|
|
|
|
<!-- type=global -->
