NAME
node - Server-side JavaScript runtime
SYNOPSIS
node [options] [v8 options] [script.js | -e "script"] [arguments]
node debug [script.js | -e "script" | <host>:<port>] ...
node [--v8-options]
Execute without arguments to start the REPL.
DESCRIPTION
Node.js is a set of libraries for JavaScript which allows it to be used
outside of the browser. It is primarily focused on creating simple,
easy to build network clients and servers.
OPTIONS
-v, --version
Print node's version.
-h, --help
Print node command line options. The output of this option is
less detailed than this document.
-e, --eval "script"
Evaluate the following argument as JavaScript.
-p, --print "script"
Identical to -e but prints the result.
-c, --check
Syntax check the script without executing.
-i, --interactive
Opens the REPL even if stdin does not appear to be a terminal.
-r, --require module
Preload the specified module at startup. Follows `require()`'s
module resolution rules. module may be either a path to a file,
or a node module name.
--no-deprecation
Silence deprecation warnings.
--trace-deprecation
Print stack traces for deprecations.
--throw-deprecation
Throw errors for deprecations.
--trace-sync-io
Prints a stack trace whenever synchronous I/O is detected after
the first turn of the event loop.
--track-heap-objects
Track heap object allocations for heap snapshots.
--zero-fill-buffers
Automatically zero-fills all newly allocated Buffer and Slow-
Buffer instances.
--prof-process
Process v8 profiler output generated using the v8 option --prof
--v8-options
Print v8 command line options.
--v8-pool-size=num
Set v8's thread pool size which will be used to allocate back-
ground jobs. If set to 0 then v8 will choose an appropriate
size of the thread pool based on the number of online proces-
sors. If the value provided is larger than v8's max then the
largest value will be chosen.
--tls-cipher-list=list
Specify an alternative default TLS cipher list. (Requires
Node.js to be built with crypto support. (Default))
--enable-fips
Enable FIPS-compliant crypto at startup. (Requires Node.js to be
built with ./configure --openssl-fips)
--force-fips
Force FIPS-compliant crypto on startup. (Cannot be disabled from
script code.) (Same requirements as --enable-fips)
--icu-data-dir=file
Specify ICU data load path. (overrides NODE_ICU_DATA)
ENVIRONMENT VARIABLES
NODE_DEBUG=module[,...]
','-separated list of core modules that should print debug
information.
NODE_PATH=path[:...]
':'-separated list of directories prefixed to the module search
path.
NODE_DISABLE_COLORS=1
When set to 1 colors will not be used in the REPL.
NODE_ICU_DATA=file
Data path for ICU (Intl object) data. Will extend linked-in data
when compiled with small-icu support.
NODE_REPL_HISTORY=file
Path to the file used to store the persistent REPL history. The
default path is ~/.node_repl_history, which is overridden by
this variable. Setting the value to an empty string ("" or " ")
disables persistent REPL history.
